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 🚀

@saaswarrior Congratulations on the launch! I’m curious, in what kinds of real-world use cases do you think the switching between modes will shine the most?

@jason123 I think- Customer Support & Agents

Non-Think mode → Fast, snappy answers to FAQs, order status, refunds.

Think mode → When a customer brings up a complicated issue (billing disputes, multi-step troubleshooting), the model can switch to deeper reasoning.

Saves cost and latency without losing problem-solving ability.

@jason123  @saaswarrior IDK if "non-think mode" is official feature name (probably hasn't been rolled to my DS account) but as a user I don't like it: I don't want my AI to be ...dumb.

@saaswarrior The hybrid Think & Non-Think modes are brilliant! Congrats on this impressive launch - excited to see how this shapes the agent era! 🚀

Love the hybrid thinking/non-thinking mode—switching between those on the fly is super smart, tbh. Gonna be wild to see what people build with this!

Congratulations on the launch! DeepSeek-V3.1 sounds like a really exciting step toward the agent era—especially the hybrid design of thinking and non-thinking modes. I’m curious, in what kinds of real-world use cases do you think the switching between modes will shine the most?

Hi just curious, is this from DeepSeek? Seems I can't see any difference in the website, is it because of the region (i'm based in UK)?
