Editorial Analysis
DeepSeek's official API documentation states that the deepseek-v4-flash model has been updated to DeepSeek-V4-Flash-0731 while keeping the same calling method. The model remains a 284B total / 13B active parameter mixture-of-experts system with 1M context support, dual thinking modes, and compatibility with OpenAI and Anthropic API formats. This formalizes the post-training upgrades for agent capabilities on the existing architecture.
