- Gemini 4 Carbon: B 62.6, rank #555 of 1518 · https://www.anchorterminal.com/tools/gemini-4-carbon.min.md
- SWE-2 Flash: F 36.4, rank #1396 of 1518 · https://www.anchorterminal.com/tools/swe-2-flash.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 29; Agent ergonomics, 93 against 10; Maintenance & community, 83 against 53; Transparency & trust, 72 against 64. 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.

Why the edge:
- Agent ergonomics, Gemini 4 Carbon +83: Gemini 4 Carbon 93 (Model reading for gemini-4-carbon on the Gemini API.); SWE-2 Flash 10 (Model reading (tool use, structured output, caching, context, batch, SDKs).)
- Schema & documentation, Gemini 4 Carbon +56: Gemini 4 Carbon 85 (Model reading for gemini-4-carbon on the Gemini API.); SWE-2 Flash 29 (Model reading.)
- Maintenance & community, Gemini 4 Carbon +30: Gemini 4 Carbon 83 (Model reading for gemini-4-carbon on the Gemini API.); SWE-2 Flash 53 (Model reading.)
- Reliability, SWE-2 Flash +10: Gemini 4 Carbon 40 (Model reading for gemini-4-carbon on the Gemini API.); SWE-2 Flash 50 (Model reading, for the surface it runs on, Devin Desktop and Devin CLI.)
- Transparency & trust, Gemini 4 Carbon +8: Gemini 4 Carbon 72 (Model reading for gemini-4-carbon on the Gemini API.); SWE-2 Flash 64 (Editorial half.)
