Anthropic Launches Claude Opus 4.5: A Powerful AI Model Focused on Coding and Enterprise Tasks

Anthropic's New Claude Opus 4.5 AI Model Is Designed for Coding and Office Work

Expertise Artificial intelligence, home energy, heating and cooling, home technology. Anthropic's newest version of its most powerful generative AI model could upend how you manage your spreadsheets. The company said Claude Opus 4.5, announced Monday, is aimed at things you do on the job, like coding and office work. Google unveiled its powerful new Gemini 3 model last week, and OpenAI released GPT-5.1 the week before. Now it's Anthropic's turn. The company, which is popular with businesses and software workers, said Opus 4.5 is focused on getting work done, not generating content. Claude Opus 4.5 will be available everywhere and will be a default model for Pro (starting at $17/month), Max (starting at $100/month) and Enterprise users. Opus 4.5 is built to produce documents, spreadsheets and presentations and can automate menial office tasks by using your computer and browser. That includes its deployment in Claude for Chrome, a browser extension that lets Claude do internet tasks for Max users. This release puts all three Claude models in the 4.5 generation. Anthropic released Sonnet 4.5, its midlevel model, in September and Haiku 4.5, its smallest model, in October. Advanced reasoning models like Opus are designed to handle complex, demanding tasks. While a smaller, cheaper large language model will provide an answer based on the probabilities in its training data, a reasoning model will rerun and refine its operations to get a better or more complete answer. This takes longer, but it means the AI can handle more difficult operations. Reasoning models are particularly useful for complicated programming projects or intensive research. The downside is they are slower and more expensive to run, which is why companies often restrict them to paid plans or have strict limits on usage.

Anthropic's new model is its latest frontier in the AI agent battle -- but it's still facing cybersecurity concerns

But the model is still too new to have made waves on LMArena yet, a popular crowdsourced AI model evaluation platform. And it's still facing the same cybersecurity issues that plague most agentic AI tools. The company's blog post also says Opus 4.5 is significantly better than its predecessor at deep research, working with slides, and filling out spreadsheets. Additionally, Anthropic is also releasing new tools within Claude Code, its coding tool, and its consumer-facing Claude apps, which it says will help with "longer-running agents and new ways to use Claude in Excel, Chrome, and on desktop." Claude Opus 4.5 is available today via Anthropic's apps, API, and all three major cloud providers, per Anthropic.

Anthropic unveils Claude Opus 4.5, its latest AI model following $350 billion valuation

Dario Amodei, co-founder and CEO of artificial intelligence startup Anthropic. Anthropic on Monday announced Claude Opus 4.5, its latest artificial intelligence model that the startup says excels at coding, using computers and assisting users with complex enterprise tasks. Claude Opus 4.5 marks Anthropic's third major model launch in two months, and it serves as the latest example of the nonstop pace of development within the AI industry. The startup unveiled its Claude Sonnet 4.5 model in late September, followed by its Claude Haiku 4.5 model in October. "The amount that we're releasing to the market and the feedback loops that we're generating from it just make me so unbelievably excited," Scott White, product leader for Claude.ai at Anthropic, told CNBC in an interview. Anthropic is an AI startup that was founded by a group of former OpenAI researchers and executives in 2021. Microsoft and Nvidia announced multi-billion-dollar investments in Anthropic last week, boosting the AI lab's valuation to about $350 billion. The company is best known for developing a family of AI models called Claude. It assigns new numbers to the models as they advance across generations, but the largest model in the family is typically called Opus, the midsized model is called Sonnet and the smallest model is Haiku.

Anthropic reveals new Opus 4.5 model, brings Claude Code to the Mac app - 9to5Mac

Anthropic has announced its latest AI model with Claude Opus 4.5. The company has also expanded Claude Code availability to the Claude desktop app for the first time. Anthropic describes its new Opus 4.5 model as "intelligent, efficient, and the best model in the world for coding, agents, and computer use." It follows Opus 4.1, which Anthropic released in August. The company shares internal first impressions of new model: As our Anthropic colleagues tested the model before release, we heard remarkably consistent feedback. Testers noted that Claude Opus 4.5 handles ambiguity and reasons about tradeoffs without hand-holding. They told us that, when pointed at a complex, multi-system bug, Opus 4.5 figures out the fix. They said that tasks that were near-impossible for Sonnet 4.5 just a few weeks ago are now within reach. Overall, our testers told us that Opus 4.5 just "gets it." Claude Opus 4.5 is also said to be more efficient, requiring fewer tokens for similar tasks, making it more affordable. Additionally, Claude Code has been added to Anthropic's desktop apps including the Mac version. Claude Code was previously limited to mobile apps and the web. It allows software engineers to code, research, and update work with multiple local and remote sessions running at the same time. Anthropic also says that Claude app users will no longer hit a wall with long conversations as frequently. With today's updates, Claude can automatically summarize earlier parts of a conversation to allow more room for continuing the chat without hitting limits.

Claude Opus 4.5 is here -- Anthropic's most powerful version to date

Hot on the heels of Gemini 3, Anthropic has just released a new AI model. Claude Opus 4.5 is the newest, most powerful version in the Claude line-up, boosting its thinking and coding abilities drastically. Anthropic offers three different versions of its Claude AI system. Haiku is the fastest and most cost-effective, Sonnet sits in the middle, blending ability and efficiency, and Opus is its most intelligent and capable model, designed for the most challenging tasks. Both Haiku and Sonnet received updates in recent months, so an Opus update was widely expected. So what is new and how does it match up to its competitors? Claude Opus 4.5 -- what's new? Unlike some of its competitors, Anthropic isn't focused on the bells and whistles. That means there are no image or video generators, and no clever add-ons like ChatGPT's new group chats. Instead, Opus 4.5 is focused on developing an effective tool for coding, office tasks and agentic modes, without sacrificing safety in the process. It can produce documents, spreadsheets and presentations with consistency and polish, while also performing repetitive tasks that you would rather not do, using agentic modes, a feature that is seeing major development across all of the big AI chatbots. This version of Claude is mostly focused on two main roles -- coding and workplace activities. With this, Anthropic has claimed that Opus 4.5 offers state-of-the-art technology for code production, as well as new ways to use Claude in Excel, Chrome and on desktop. For all Max users on Claude, you will now be able to use Claude for Chrome, letting the AI tool take control of your Chrome browser and complete tasks on your behalf. This is similar to the likes of ChatGPT Agent, Perplexity's Comet agent or Gemini 3. Anthropic has also announced that it is dealing with one of the biggest complaints it had from users, eliminating context window limit errors. This is due to a new feature called 'Infinite Chats'. This will leverage memory to maintain context and consistency across different files. However, this is exclusively available to those on paid plans. What can you use Opus 4.5 for? At its core, Opus 4.5 is simply an upgraded version of its predecessor. That means improvements to its reasoning, context, speed and general performance. However, there are a couple of areas where the upgrade will be most notable. Agents Claude Opus 4.5 is Anthropic's biggest push into the world of agentic AI to date. This involves the AI tool taking on more tasks on your behalf, utilizing Chrome to complete searches, payments, reservations and more. Coding For Anthropic, one of the areas it's seen serious progress on with previous updates is coding. Claude Opus 4.5 becomes its best coding model to date. For Anthropic, they want this to work as well as a senior engineer would, no longer requiring hand-holding or assistance from the user. This, in theory, could include fixing its own bugs and developing structurally sound code, even on more complicated tasks. Complex tasks on Enterprise plans As mentioned above, Anthropic is looking to become the go-to AI system for companies. With its Enterprise plan, where you can securely connect Claude to your company knowledge, Anthropic claims Opus 4.5 is better than ever. In testing, Anthropic claims that it achieves state-of-the-art results in this area, combining information retrieval, tool use and deep analysis. Financial modeling Anthropic also claims that Claude Opus 4.5 sets a new standard for Excel automation. Early customers saw 20% accuracy improvements on internal evaluations, 15% efficiency gains, and complex tasks that were previously deemed unachievable. Who is this update for? Based on the improvements made, Claude Opus 4.5 is for the serious power users of AI. It sees big changes for developers, businesses and those who are primarily focused on coding and work. Unlike OpenAI, Anthropic has made a big push for the world of businesses, looking to solve complex reasoning problems and fixing large scale issues within a companies infrastructure. However, for those who like to make the most of powerful AI in their personal lives, this update shouldn't be discounted. This will become Anthropic's most powerful model to date, especially in its ability to code, and take on big thinking projects.

Anthropic's Claude Opus 4.5 is here: cheaper AI, infinite chats, and coding skills that beat humans

Anthropic released its most capable artificial intelligence model yet on Monday, slashing prices by roughly two-thirds while claiming state-of-the-art performance on software engineering tasks -- a strategic move that intensifies the AI startup's competition with deep-pocketed rivals OpenAI and Google. The new model, Claude Opus 4.5, scored higher on Anthropic's most challenging internal engineering assessment than any human job candidate in the company's history, according to materials reviewed by VentureBeat. The result underscores both the rapidly advancing capabilities of AI systems and growing questions about how the technology will reshape white-collar professions. The Amazon-backed company is pricing Claude Opus 4.5 at $5 per million input tokens and $25 per million output tokens -- a dramatic reduction from the $15 and $75 rates for its predecessor, Claude Opus 4.1, released earlier this year. The move makes frontier AI capabilities accessible to a broader swath of developers and enterprises while putting pressure on competitors to match both performance and pricing. "We want to make sure this really works for people who want to work with these models," said Alex Albert, Anthropic's head of developer relations, in an exclusive interview with VentureBeat. "That is really our focus: how can we enable Claude to be better at helping you do the things that you don't necessarily want to do in your job?" The announcement comes as Anthropic races to maintain its position in an increasingly crowded field. OpenAI recently released GPT-5.1 and a specialized coding model called Codex Max that can work autonomously for extended periods. Google unveiled Gemini 3 just last week, prompting concerns even from OpenAI about the search giant's progress, according to a recent report from The Information. Claude Opus 4.5 demonstrates improved judgment on real-world tasks, developers say Anthropic's internal testing revealed what the company describes as a qualitative leap in Claude Opus 4.5's reasoning capabilities. The model achieved 80.9% accuracy on SWE-bench Verified, a benchmark measuring real-world software engineering tasks, outperforming OpenAI's Sonnet 4.5 (77.2%) and Google's Gemini 3 Pro (76.2%), according to the company's data. But the technical benchmarks tell only part of the story. Albert said employee testers consistently reported that the model demonstrates improved judgment and intuition across diverse tasks -- a shift he described as the model developing a sense of what matters in real-world contexts. "The model just kind of gets it," Albert said. "It just has developed this sort of intuition and judgment on a lot of real world things that feels qualitatively like a big jump up from past models." He pointed to his own workflow as an example. Previously, Albert said, he would ask AI models to gather information but hesitated to trust their synthesis or prioritization. With Opus 4.5, he's delegating more complete tasks, connecting it to Slack and internal documents to produce coherent summaries that match his priorities. AI model outscores all human candidates on company's toughest engineering test The model's performance on Anthropic's internal engineering assessment marks a notable milestone. The take-home exam, designed for prospective performance engineering candidates, is meant to evaluate technical ability and judgment under time pressure within a prescribed two-hour limit. Using a technique called parallel test-time compute -- which aggregates multiple attempts from the model and selects the best result -- Claude Opus 4.5 scored higher than any human candidate who has taken the test, according to the press release. Without a time limit, the model matched the performance of the best-ever human candidate when used within Claude Code, Anthropic's coding environment. The company acknowledged that the test doesn't measure other crucial professional skills such as collaboration, communication, or the instincts that develop over years of experience. Still, Anthropic said the result "raises questions about how AI will change engineering as a profession." Albert emphasized the significance of the finding. "I think this is kind of a sign, maybe, of what's to come around how useful these models can actually be in a work context and for our jobs," he said. "Of course, this was an engineering task, and I would say models are relatively ahead in engineering compared to other fields, but I think it's a really important signal to pay attention to." Dramatic efficiency improvements cut token usage by up to 76% on key benchmarks Beyond raw performance, Anthropic is betting that efficiency improvements will differentiate Claude Opus 4.5 in the market. The company says the model uses dramatically fewer tokens -- the units of text that AI systems process -- to achieve similar or better outcomes compared to predecessors. At a medium effort level, Opus 4.5 matches the previous Sonnet 4.5 model's best score on SWE-bench Verified while using 76% fewer output tokens, according to Anthropic. At the highest effort level, Opus 4.5 exceeds Sonnet 4.5 performance by 4.3 percentage points while still using 48% fewer tokens. To give developers more control, Anthropic introduced an "effort parameter" that allows users to adjust how much computational work the model applies to each task -- balancing performance against latency and cost. Enterprise customers provided early validation of the efficiency claims. "Opus 4.5 beats Sonnet 4.5 and competition on our internal benchmarks, using fewer tokens to solve the same problems," said Michele Catasta, president of Replit, a cloud-based coding platform, in a statement sent to VentureBeat. "At scale, that efficiency compounds." GitHub's chief product officer, Mario Rodriguez, said early testing shows Opus 4.5 "surpasses internal coding benchmarks while cutting token usage in half, and is especially well-suited for tasks like code migration and code refactoring." Early customers report AI agents that learn from experience and refine their own skills One of the most striking capabilities demonstrated by early customers involves what Anthropic calls "self-improving agents" -- AI systems that can refine their own performance through iterative learning. Rakuten, the Japanese e-commerce and internet company, tested Claude Opus 4.5 on automation of office tasks. "Our agents were able to autonomously refine their own capabilities -- achieving peak performance in 4 iterations while other models couldn't match that quality after 10," said Yusuke Kaji, Rakuten's general manager of AI for business. Albert explained that the model isn't updating its own weights -- the fundamental parameters that define an AI system's behavior -- but rather iteratively improving the tools and approaches it uses to solve problems. "It was iteratively refining a skill for a task and seeing that it's trying to optimize the skill to get better performance so it could accomplish this task," he said. The capability extends beyond coding. Albert said Anthropic has observed significant improvements in creating professional documents, spreadsheets, and presentations. "They're saying that this has been the biggest jump they've seen between model generations," Albert said. "So going even from Sonnet 4.5 to Opus 4.5, bigger jump than any two models back to back in the past." Fundamental Research Labs, a financial modeling firm, reported that "accuracy on our internal evals improved 20%, efficiency rose 15%, and complex tasks that once seemed out of reach became achievable," according to co-founder Nico Christie. New features target Excel users, Chrome workflows and eliminate chat length limits Alongside the model release, Anthropic rolled out a suite of product updates aimed at enterprise users. Claude for Excel became generally available for Max, Team, and Enterprise users with new support for pivot tables, charts, and file uploads. The Chrome browser extension is now available to all Max users. Perhaps most significantly, Anthropic introduced "infinite chats" -- a feature that eliminates context window limitations by automatically summarizing earlier parts of conversations as they grow longer. "Within Claude AI, within the product itself, you effectively get this kind of infinite context window due to the compaction, plus some memory things that we're doing," Albert explained. For developers, Anthropic released "programmatic tool calling," which allows Claude to write and execute code that invokes functions directly. Claude Code gained an updated "Plan Mode" and became available on desktop in research preview, enabling developers to run multiple AI agent sessions in parallel. Market heats up as OpenAI, Google race to match performance and pricing Anthropic reached $2 billion in annualized revenue during the first quarter of 2025, more than doubling from $1 billion in the prior period. The number of customers spending more than $100,000 annually jumped eightfold year-over-year. The rapid release of Opus 4.5 -- just weeks after Haiku 4.5 in October and Sonnet 4.5 in September -- reflects broader industry dynamics. OpenAI released multiple GPT-5 variants throughout 2025, including a specialized Codex Max model in November that can work autonomously for up to 24 hours. Google shipped Gemini 3 in mid-November after months of development. Albert attributed Anthropic's accelerated pace partly to using Claude to speed its own development. "We're seeing a lot of assistance and speed-up by Claude itself, whether it's on the actual product building side or on the model research side," he said. The pricing reduction for Opus 4.5 could pressure margins while potentially expanding the addressable market. "I'm expecting to see a lot of startups start to incorporate this into their products much more and feature it prominently," Albert said. Yet profitability remains elusive for leading AI labs as they invest heavily in computing infrastructure and research talent. The AI market is projected to top $1 trillion in revenue within a decade, but no single provider has established dominant market position -- even as models reach a threshold where they can meaningfully automate complex knowledge work. Michael Truell, CEO of Cursor, an AI-powered code editor, called Opus 4.5 "a notable improvement over the prior Claude models inside Cursor, with improved pricing and intelligence on difficult coding tasks." Scott Wu, CEO of Cognition, an AI coding startup, said the model delivers "stronger results on our hardest evaluations and consistent performance through 30-minute autonomous coding sessions." For enterprises and developers, the competition translates to rapidly improving capabilities at falling prices. But as AI performance on technical tasks approaches -- and sometimes exceeds -- human expert levels, the technology's impact on professional work becomes less theoretical. When asked about the engineering exam results and what they signal about AI's trajectory, Albert was direct: "I think it's a really important signal to pay attention to."

With new Opus 4.5 model, Anthropic's Claude could remain the best AI coding tool

Claude Code is already widely used by developers, and with a new brain, it may fend off Google's new Antigravity tool. Anthropic launched its newest model, Claude Opus 4.5, putting the company back atop the benchmark rankings for AI software coding. Opus 4.5 scores over 80% on the widely-used SWE-bench, which tests models for software engineering skill. Google's impressive Gemini 3 Pro, launched last week, briefly held the top score with 76.2%. Anthropic's Claude product lead Scott White tells Fast Company that the model has also scored higher than any human on the engineering take-home assignment the company gives to engineering job candidates.

Anthropic releases new flagship Claude Opus 4.5 model - SiliconANGLE

Anthropic PBC today launched Claude Opus 4.5, its new flagship large language model. The company says Opus 4.5 is its safest and most capable LLM yet. The model is rolling out a few weeks after the two other entries into the Claude 4.5 series: Sonnet 4.5 and Haiku 4.5. The LLMs are positioned as midrange and entry-level alternatives to Opus 4.5, respectively. According to Anthropic, Opus 4.5 is better than the competition at powering artificial intelligence agents that use tools to automate work. When agents based on the model encounter a task they can't complete on their first try, they can iteratively refine their capabilities. Anthropic says that Opus 4.5 reaches "peak performance" after four iterations, while other LLMs require 10 attempts. Opus 4.5 also brings other improvements. Compared to Anthropic's other models, it provides better support for long-running agents. That should make the LLM more useful for tasks such as rewriting applications that can take several hours. Developers often automate complex, long-running tasks using not one but several agents that coordinate their work. According to Anthropic, software teams pursuing such projects can use Opus 4.5 to power the lead agent and the entry-level Haiku 4.5 to power sub-agents. Assigning simple processing steps to a lightweight LLM lowers inference costs. Programming is another area where Optus 4.5 provides better performance than its predecessors. According to Anthropic, the model requires less human guidance and handles ambiguity better. A developer could, for example, ask Opus 4.5 to troubleshoot a bug without specifying that fixing it requires the model to review multiple systems. The model's new reasoning features are complemented by integrations with Excel and Google Chrome. Anthropic first introduced the Excel integration last month as a research preview. The add-on rolled out to Claude for Financial Services, a feature bundle geared towards financial professionals. It makes Claude accessible through a sidebar in the Excel interface. The integration is now generally available for users with Max, Team, and Enterprise subscriptions. Anthropic has added support for pivot tables, tables that are used to summarize information spread across a large number of spreadsheet fields. Additionally, users can now upload files and generate charts. Claude's Chrome integration debuted two months before the Excel add-on. It's a browser extension that enables the chatbot to perform actions in web applications on the user's behalf. At the time of its introduction, Anthropic stated that the feature includes mitigations against malicious prompts embedded in web content. The Chrome extension initially rolled out to 1,000 users of Claude's top-end Max plan. Today, Anthropic made the feature generally available to all Max subscribers. The company also released a number of other enhancements as part of today's update. The Claude Code programming assistant is now available in Anthropic's desktop client, while the Max and Teams plans have received higher usage caps. Claude Chat, in turn, is gaining the ability to summarize information from earlier parts of a chat session. Opus 4.5 is available through Claude Chat, Claude Code and application programming interfaces. Developers who use the APIs have access to a new "effort" setting that makes it possible to adjust the amount of time and computing capacity the LLM uses to perform a task. The more infrastructure is allocated to a task, the higher the output quality. Opus 4.5 is priced at $5 per million input tokens and $25 per million output tokens.

Anthropic Tipped to Launch the Claude Opus 4.5 AI Model This Week

Anthropic could release the frontier model of its Claude 4.5 family soon. As per the tipster, the Claude Opus 4.5 artificial intelligence (AI) model was spotted on another platform, while the model's release table was also spotted separately. Based on the leaks, it is said that the large language model could arrive on Monday, bringing improvement across various parameters. Not a lot is known about the AI model at present, but based on the improvements in Claude 4.5 Sonnet and Claude 4.5 Haiku, coding performance and agentic capabilities could be a major focus area. Anthropic Could Release Claude Opus 4.5 Soon Tipster @kimmonismus on X (formerly known as Twitter), claimed in a post that Anthropic's Claude Opus 4.5 was being readied for release and it was spotted on Poe, an AI chatbot platform that hosts third-party models. Later, in a separate post, the tipster shared a release table of the LLM, claiming it is scheduled to be released on Monday, November 24. Social media on Sunday wa abuzz with rumours about the release of Anthropic's frontier model. Founder of Zenjoy, Peter Dedene, also shared a screenshot of the release table that mentions that "Claude Kayak" is releasing on Monday. It is said that Kayak is an internal nickname for Opus 4.5. Apart from leaks about its release date, no other reliable information about the AI models is currently known. It has been speculated that the AI model will further improve code generation and bring greater agentic capabilities to users; however, upgrades in other areas are not known. Notably, Anthropic released Claude 4.5 Sonnet in September and Claude 4.5 Haiku, the fastest model in the family, arrived in October. These models displayed improvements in coding, agentic operations, computer use, reasoning, and domain-specific knowledge. Sonnet also managed a score of 77.2 percent on the SWE bench-Verified benchmark, which tests AI models on their coding capabilities. This score was higher than what OpenAI's GPT-5 and Google's Gemini 2.5 achieved. Meanwhile, recently, Claude was used to conduct a large-scale agentic cyberattack. In a detailed analysis, Anthropic claimed it to be first-of-its-kind incident where the AI carried out most of the hacking, with minimal input from a human operator.
