Open-weight does not mean license-free. Common 2026 license patterns: Apache 2.0 / MIT (truly permissive — Mistral, Qwen, Phi) with no commercial restrictions; Llama Community License (free up to 700M MAU, then requires Meta license); Gemma terms (Google-specific use restrictions); FLUX-1-Dev (non-commercial), FLUX-1-Schnell (Apache 2.0); Stable Diffusion 3 Medium (community license with revenue limits); custom 'Responsible AI' licenses with use-case restrictions. Production gotcha: legal must review before shipping; license terms can change between versions; some licenses prohibit competitive use (training models on outputs). Read the LICENSE file before integrating.

## When to use

- Before shipping any open-weight model in production.

## Common mistakes

- Skipping the LICENSE file — assuming permissive when it isn't.
- Not tracking license changes between versions — a v2 may have stricter terms than v1.
