deepseek-ai/DeepSeek-V4-Flash-0731 (via) The latest release in DeepSeek's V4 family, "with substantially enhanced agentic capabilities". It's 304 billion parameters - 167GB on Hugging Face - but it appears to punch well above its weight.
Artificial Analysis rank it ahead of MiniMax M3 - a 428B model. It's $0.14/million input and $0.27/million output pricing means this may currently be the best value-per-intelligence model out there. It's looking very good on the Intelligence Index vs. Cost per Intelligence Index Task chart:
I got a disappointing pelican from it using the default reasoning level via OpenRouter:
But when I bumped reasoning level up to high I got something much better:
