Performance Metrics Demonstrate Competitive Capabilities

DeepSeek V4-Flash achieved an impressive 82.7 score on Terminal Bench, surpassing DeepSeek's own Pro version by 10 points

4

. In cybersecurity assessments, the model scored 76.7, doubling the 38.7 achieved by its preview version

4

. The AI model also outperformed GLM 5.2 in software engineering tasks with a score of 52.7 compared to GLM's 46.2

4

. According to Artificial Analysis's Intelligence Index, V4-Flash scored 50 out of 100, tying with Google's Gemini 3.6 Flash and sitting just one point below Meta's Muse Spark 1.1 and Z.AI's GLM-5.2

Mixture-of-Experts Architecture Drives Efficiency

The model uses a Mixture-of-Experts (MoE) architecture with 284 billion total parameters while activating only 13 billion parameters during inference for greater efficiency

5

. This architectural approach allows DeepSeek V4-Flash to deliver high performance without increasing computational demands or modifying its core structure. The AI model supports a one-million-token context window, enabling developers to process significantly larger datasets and longer conversations

5

. The success demonstrates that post-training optimization focusing on strategic planning, error correction, and precise execution can yield better outcomes than simply increasing model complexity

2

. The flash model achieves up to seven times the performance of the original DeepSeek 2 in specific benchmarks, proving that smarter refinement can outperform traditional scaling approaches

Affordable AI Solutions Expand Market Accessibility

DeepSeek V4-Flash ranks 10th overall in AI benchmarks, a remarkable achievement for a model of its size and cost

3

. The input token pricing of $0.0028 per million tokens is lower than the $0.003625 charged for the Pro version, while output token pricing of $0.28 represents a significant reduction compared to the Pro version's $0.87

4

. This pricing strategy positions the model as an ideal choice for budget-conscious users requiring reliable AI capabilities without compromising performance. The cost efficiency delivers near Luna-level intelligence at a fraction of the cost, making it attractive for organizations aiming to maximize return on investment

3

. Artificial Analysis favors cost-per-test over sticker price because models that appear cheap per token may still accumulate large bills if they require many more steps to reach correct answers
