DeepSeek-V3.1 is the latest AI model from DeepSeek, designed specifically for China-made chips with a “Think/Non-Think” hybrid inference system, faster responses, and updated API pricing from September 6, 2025.
What’s New in DeepSeek-V3.1?
Hybrid Inference Architecture
DeepSeek-V3.1 introduces a “Think / Non-Think” toggle—meaning one model handles both reasoning-heavy and routine tasks, all switchable via a “deep thinking” button on its app and web interface.Faster and Smarter
The “Think” mode delivers quicker answers than the previous DeepSeek-R1-0528, while maintaining output quality. [Source]

People Also Ask
What does “hybrid inference” mean in DeepSeek-V3.1?
It means the model offers two modes—’Think’ for complex, reasoning tasks, and ‘Non-Think’ for lighter ones—selectable via a toggle.
How is DeepSeek-V3.1 optimized for Chinese chips?
It adopts the UE8M0 FP8 precision format, tailor-made for next-gen Chinese semiconductors, enabling efficient, faster operation.
What changes to DeepSeek’s API pricing start Sept 6, 2025?
DeepSeek will implement revised pricing for API access on that date, though specific rates haven’t been publicly released yet.
What is UE8M0 FP8 precision?
A highly efficient 8-bit floating precision format designed to optimize memory usage and speed for domestic Chinese chips.
Can I still use DeepSeek’s older models?
Yes, R1 and earlier V3 versions remain available, though V3.1 offers better speed and chip compatibility.
Will the “Think” mode cost more in API usage?
Official pricing hasn’t specified mode-based costs yet—expect details around September.
Which Chinese chip brands support V3.1?
DeepSeek hasn’t named specific chips yet—UE8M0 is just labeled for “next-gen domestic chips”.
Is DeepSeek-V3.1 open-source?
V3 was MIT-licensed; V3.1 has open-source weights available via Hugging Face.
DeepSeek-V3.1 marks a major step in China’s march toward AI self-sufficiency. With hybrid inference and chip-optimized performance, plus an API cost reset in September, it’s both more powerful and pragmatic. Whether you’re a developer or just curious, keep an eye on V3.1—it’s where AI meets national strategy.
I am not sure where youre getting your info but good topic I needs to spend some time learning much more or understanding more Thanks for magnificent info I was looking for this information for my mission
I have been surfing online more than 3 hours today yet I never found any interesting article like yours It is pretty worth enough for me In my opinion if all web owners and bloggers made good content as you did the web will be much more useful than ever before
