- Gemini 4 Carbon: B 62.6, rank #555 of 1518 · https://www.anchorterminal.com/tools/gemini-4-carbon.min.md
- Prism Inference: C 59.6, rank #695 of 1518 · https://www.anchorterminal.com/tools/prism-inference.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 Agent ergonomics, 93 against 68; Maintenance & community, 83 against 49; Transparency & trust, 72 against 63.
- Prism Inference, good for Coding agents that want DeepSeek-V4.1-Flash at a low input price, with no retention, through whichever of the three wire formats the harness already speaks. Ahead on Reliability, 65 against 40; Security & auth, 68 against 55.
