When to choose each
Grok 4.6
Best for
- Coding, agentic, and knowledge-work API evaluations with controlled long-context cost
Watch out for
- Published token rates increase for all tokens in a request once its prompt reaches xAI's 200,000-token long-context threshold
Muse Glimmer
Best for
- Local or on-device coding agents on a single GPU
- Fine-tuning an Apache 2.0 multimodal base
Watch out for
- Self-hosted only: Meta does not serve it over its Model API, so there is no first-party per-token price
- Audio is not supported and video is read as individual frames; the default context is 128K tokens
