Gemini 4 Carbon scores 62.6 (B) on agent readiness against Muse Ember's 51.8 (D), and leads in 4 of 7 scored categories. Muse Ember leads on security & auth. Both do llm inference.

- Gemini 4 Carbon: B 62.6, rank #555 of 1518 · https://www.anchorterminal.com/tools/gemini-4-carbon.min.md
- Muse Ember: D 51.8, rank #1020 of 1518 · https://www.anchorterminal.com/tools/muse-ember.min.md
- Gemini 4 Carbon, good for Agents on the hardest long tasks (multi-step debugging, large codebases, open-ended research, security work) that can pay frontier prices and already use the Gemini API. Ahead on Schema & documentation, 85 against 60; Agent ergonomics, 93 against 72; Maintenance & community, 83 against 46; Transparency & trust, 72 against 53.
- 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 Security & auth, 64 against 55.
