- Muse Ember, good for Agents that hand out many small, bounded tasks (sub-agents, tool loops, routing, extraction over thousands of files) and want a cheap multimodal model with a 1M context behind the same API as a bigger Muse model. Ahead on Schema & documentation, 60 against 29; Agent ergonomics, 72 against 10; Security & auth, 64 against 53. Also A hosted endpoint, with nothing to install.
- SWE-2 Flash, good for People already using Devin Desktop or Devin CLI who want a cheaper, faster model for routine coding work such as automations, reviews and small changes, while it is free in November 2026. Ahead on Reliability, 50 against 40; Maintenance & community, 53 against 46; Transparency & trust, 64 against 53.

Why the edge:
- Agent ergonomics, Muse Ember +62: Muse Ember 72 (Model reading.); SWE-2 Flash 10 (Model reading (tool use, structured output, caching, context, batch, SDKs).)
- Schema & documentation, Muse Ember +31: Muse Ember 60 (Model reading.); SWE-2 Flash 29 (Model reading.)
- Security & auth, Muse Ember +11: Muse Ember 64 (Platform readings are the meta-model-api listing's of 4 November.); SWE-2 Flash 53 (Read as a hosted model reached through Devin's local clients.)
- Transparency & trust, SWE-2 Flash +11: Muse Ember 53 (Editorial half.); SWE-2 Flash 64 (Editorial half.)
- Reliability, SWE-2 Flash +10: Muse Ember 40 (Model reading, for the surface it's called on, Meta Model API.); SWE-2 Flash 50 (Model reading, for the surface it runs on, Devin Desktop and Devin CLI.)
- Maintenance & community, SWE-2 Flash +7: Muse Ember 46 (Model reading.); SWE-2 Flash 53 (Model reading.)
