Gemini 4 Carbon scores 62.6 (B) on agent readiness against DeepSeek API's 46.7 (D), and leads in 5 of 7 scored categories. DeepSeek API leads on reliability. Both do llm inference.

- DeepSeek API: D 46.7, rank #1175 of 1518 · https://www.anchorterminal.com/tools/deepseek-api.min.md
- Gemini 4 Carbon: B 62.6, rank #555 of 1518 · https://www.anchorterminal.com/tools/gemini-4-carbon.min.md
- DeepSeek API, good for Low-cost long-context work on public data, and off-peak batch-style jobs run through the normal API. Ahead on Reliability, 60 against 40.
- 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 49; Agent ergonomics, 93 against 70; Security & auth, 55 against 35; Maintenance & community, 83 against 46; Transparency & trust, 72 against 65. Also No incidents deducted, where DeepSeek API loses 3 points for them.
