Questions about alternatives to Gemini 3.1 Deep Think

What is the best open source alternative to Gemini 3.1 Deep Think?

DeepSeek-V3.2-Speciale is listed first. Choose DeepSeek-V3.2-Speciale when you want open weights for hard maths and coding problems without a Google AI Ultra subscription.

Is there a free alternative to Gemini 3.1 Deep Think?

Yes. The code of all 3 is public under MIT or Apache 2.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

How do I choose between them?

Start from the job you use Gemini 3.1 Deep Think for. Choose Nomos 1 when you want an Apache-licensed maths reasoning model you can download, not a Google AI Ultra plan. Choose NousCoder-14B when you want a 14B Apache-licensed model for competitive programming that you can run locally.

Which Gemini 3.1 Deep Think alternatives can I host on my own server?

All 3: DeepSeek-V3.2-Speciale, Nomos 1 and NousCoder-14B. Each tool's page says what it needs to run.

What licences do they use?

Apache 2.0 (2), MIT (1). MIT, BSD and Apache let you change and reuse the code freely.

What do I lose by leaving Gemini 3.1 Deep Think?

The hosting. Gemini 3.1 Deep Think's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
