Hey Hunters 👋

I am excited to hunt DeepSeek-V3.1 — our first step toward the agent era!

✅ Hybrid inference: Think & Non-Think — one model, two modes

✅ Faster reasoning: DeepSeek-V3.1-Think answers quicker than R1-0528

✅ Stronger agent skills: Improved tool use + multi-step task handling

✅ 128K context for both chat & reasoner modes

✅ Strict Function Calling support in Beta API

✅ Better performance on SWE/Terminal-Bench + complex reasoning tasks

✅ Open-source weights available for the community

You can even toggle between Think & Non-Think modes via the new DeepThink button.

We’d love your thoughts as we continue building toward smarter, faster, and more capable AI agents 🚀
