. This new AI model represents a significant advancement in the field of AI-powered coding assistants, offering improved efficiency and accuracy for software developers.

Unique Features of Mellum

Unlike typical large language models, Mellum is built exclusively for coding purposes. Valerie Kazmina, product marketing manager at JetBrains, emphasized that Mellum is "a smaller, optimized model that significantly reduces latency, offering developers suggestions almost instantly"

. This specialized focus allows Mellum to outperform many third-party models currently available in the market in terms of efficiency.

Integration and Performance

Mellum has been integrated into the JetBrains AI Assistant, an intelligent coding companion available to users of the company's independent development editors

. These editors combine various tasks such as writing code, building, debugging, and testing software into a single platform.

According to JetBrains' testing, Mellum has demonstrated impressive performance improvements:

  1. Reduced suggestion time: The time taken to produce code suggestions has decreased by up to one-third compared to previous models

The availability of Mellum's features depends on the user's subscription:

  • Cloud-based code completion is available for users with an AI Pro subscription.
  • Local AI-powered code completion is bundled by default for users with paid versions of JetBrains' IntelliJ-based IDE
