Our take
Written Sep 29, 2026Llama 4 Maverick is a downloadable model you can run yourself, with text and image input and room for long documents in one request. Its measured quality sits in the bottom quarter of every board we hold, so it is a model to trial on work you can check, not a safe default.
Consider it only for experiments where a downloadable model with a custom licence is acceptable and you can judge the output yourself. The licence puts conditions on commercial use and redistribution, so it needs reading before you build on it. Skip it if you need fixes landed in an existing codebase without review, or if you need measured quality that stands near the top of a board.
The case for it
- You can download it and run it yourself, so a host is optional rather than the only route.
- The request capacity takes long documents without splitting them up first, though reliable recall across all of it is unverified in our data.
- Text and images go into the same request, so a screenshot does not have to be described in words first.
The case against it
- Weak across every board we hold: 134th of 168 on Arena Text (overall) as of 25 Sep 2026, with its Creative Writing and Coding placings also in the bottom quarter of their fields.
- Coding on real issues is near the bottom of its field: 40th of 42 on SWE-bench Verified via mini-SWE-agent as of 19 Feb 2026, which measures real GitHub issues resolved end-to-end inside that harness.
- The custom licence puts conditions on commercial use and redistribution, so it needs reading before you build on it.
How good is it?
An open text model for chat and code, though it trails most models on everyday questions and coding.

Room to spare. 121.2 GB spare means a 10% error in the size would not change the answer.

Across the 5 listings we hold: 4 say they do not train on prompts (1 of them only through OpenRouter), 0 say they do and 1 does not say. 4 appear in the zero-retention registry we check (1 of them only through OpenRouter); the rest are unknown to us.
What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet
- We hold no measured file for it, so all 3 sizes on this page are calculated from the parameter count.
- Nothing we hold says whether an endpoint streams, so we do not show it either way.
- 1 of 5 listings does not say whether it trains on prompts, and 1 answers only through OpenRouter, not for its own listing.
- We hold no batch or off-peak rate for any of its listings.
- We hold a decode speed for it, but no prompt-processing (prefill) figure, so how long the input side of a job takes is unknown to us.

Custom licence
This model ships custom license terms that don't map to a known template. We haven't parsed them, so commercial use, redistribution and derivatives are unverified — review the original terms before shipping.
