- 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. Also No incidents deducted, where OpenRouter loses 3 points for them.
- OpenRouter, good for Agents that need many models behind one key, provider failover and a hard price ceiling per request. Ahead on Reliability, 55 against 40; Schema & documentation, 90 against 60; Agent ergonomics, 85 against 72; Payments & pricing, 40 against 20; Maintenance & community, 82 against 46; Transparency & trust, 72 against 53.
