DeepSeek-V4-Flash API Public Beta: Agent Capabilities Boosted Purely via Post-Training
新智元 · wechat · 2026-07-31
DeepSeek has announced the public beta of the V4-Flash official API. The core breakthrough is that this version achieves massive improvements in Agent planning and coding capabilities purely through post-training, while keeping the model architecture and size completely unchanged.
Key Updates:
- Capability Upgrade: Significant score jumps in complex coding benchmarks like DSBench, with some results rivaling much larger models.
- Developer Integration: Natively supports the Responses API to solve JSON parsing failures with 100% stable structured output. It also fully adapts to OpenAI Codex for seamless integration into tools like VSCode.
- Roadmap: The more powerful V4-Pro official version is still under development and will be released at a later date.
