# MIT — what it permits, and which models carry it

7 of the 24 models in the AI Token Router catalogue are published under MIT: GLM-5.2, GLM-5.2 Air, DeepSeek V4 Pro, DeepSeek V4 Flash, MiniMax M2, HiDream-I1 and BGE-M3. Commercial use is permitted outright by the licence text.

MIT is a standard permissive licence: it allows commercial use, modification and redistribution of what it covers, and its only obligation is that the copyright and licence notice travels with any copy you distribute.

Canonical text: https://opensource.org/licenses/MIT

Commercial use: **Yes** — A standard permissive text that allows commercial use outright, with no user threshold and no field-of-use restriction.

## Permits

- Commercial use, including inside a product you charge for
- Modification, including fine-tuning, and redistribution of the result
- Redistribution and sublicensing
- Private use, with no obligation to publish anything you build

## Requires

- Keep the copyright notice and the licence text with any copy you distribute

## Restricts

- Nothing further. The text sets no user threshold, no field-of-use restriction and no separate acceptable-use policy
- The work is provided as is: the licence disclaims warranty and liability

## Models under MIT

**Availability:** 7 of the 24 catalogued models are callable today. The rest are listed at their intended rate but no configured upstream serves them, so a request naming one returns `no available channel`. Every table below marks which is which.

## Questions

### Can I use MIT models commercially?

Yes. MIT is a standard permissive licence: it allows commercial use, modification and redistribution of what it covers, and its only obligation is that the copyright and licence notice travels with any copy you distribute. This is a reference, not legal advice. It exists so you can arrive at your own counsel with a sharper question than whether you are allowed to use the model.

### What does MIT require me to do?

Keep the copyright notice and the licence text with any copy you distribute. Those are the conditions the standard text attaches; the text itself is the authority and is linked on this page.

### Which models under MIT can I call today?

3 of the 7: GLM-5.2, DeepSeek V4 Pro, DeepSeek V4 Flash. The rest are catalogued at their intended rate but not currently served by an upstream. Across the whole catalogue, 7 of 24 models are callable today.

This is a reference, not legal advice. It exists so you can arrive at your own counsel with a sharper question than whether you are allowed to use the model.
