Originally published on Simon Willison's Weblog by Simon Willison

Summary & Key Takeaways
• DeepSeek-V4-Flash-0731 is a new 304 billion parameter LLM. • It boasts substantially enhanced agentic capabilities. • Artificial Analysis ranks it ahead of the larger MiniMax M3 model. • Its pricing suggests it might be the best value-per-intelligence model available. • Initial tests show improved results when using higher reasoning levels. • The model is available on Hugging Face and OpenRouter.
Our Commentary
Another day, another massive LLM. What really catches my eye here is the "value-per-intelligence" aspect. We're seeing these models get incredibly powerful, but the cost often makes them prohibitive for smaller projects. If DeepSeek can genuinely deliver top-tier performance at a lower price point, that's a game-changer for accessibility. I'm also intrigued by the "enhanced agentic capabilities" – that's where the real innovation is happening right now.
