What is the best open source alternative to MiniMax M2.1?
GLM-4.7 is listed first. Z.ai's MIT-licensed model for coding with 200K context.
Is there a free alternative to MiniMax M2.1?
Yes. The code of all 2 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.
Which MiniMax M2.1 alternatives can I host on my own server?
All 2: GLM-4.7 and Qwen3-Coder-Next. Each tool's page says what it needs to run.
What licences do they use?
MIT (1), Apache 2.0 (1). MIT, BSD and Apache let you change and reuse the code freely.
What do I lose by leaving MiniMax M2.1?
The hosting. MiniMax M2.1'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.
