Gemini 4 Carbon scores 62.6 (B) on agent readiness against Beam 1.0's 53.4 (D), and leads in 6 of 7 scored categories. Beam 1.0 leads on reliability. Both do llm inference.

- Gemini 4 Carbon: B 62.6, rank #555 of 1518 · https://www.anchorterminal.com/tools/gemini-4-carbon.min.md
- Beam 1.0: D 53.4, rank #953 of 1518 · https://www.anchorterminal.com/tools/reflection-beam.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 67; Security & auth, 55 against 45; Payments & pricing, 20 against 10; Maintenance & community, 83 against 50; Transparency & trust, 72 against 57.
- Beam 1.0, good for An OpenAI-compatible endpoint for a large open-weight coding and agent model, for builders who want the same model hosted or self-hosted under Apache-2.0. Ahead on Reliability, 52 against 40.

Why the edge:
- Maintenance & community, Gemini 4 Carbon +33: Gemini 4 Carbon 83 (Model reading for gemini-4-carbon on the Gemini API.); Beam 1.0 50 (Model reading.)
- Agent ergonomics, Gemini 4 Carbon +26: Gemini 4 Carbon 93 (Model reading for gemini-4-carbon on the Gemini API.); Beam 1.0 67 (Model reading (tool use, structured output, caching, context, batch, SDKs and defaults, errors).)
- Transparency & trust, Gemini 4 Carbon +15: Gemini 4 Carbon 72 (Model reading for gemini-4-carbon on the Gemini API.); Beam 1.0 57 (Weights under Apache-2.0, an OSI licence, per the model card, which says the licence doesn't restrict distillation or training on outputs.)
- Reliability, Beam 1.0 +12: Gemini 4 Carbon 40 (Model reading for gemini-4-carbon on the Gemini API.); Beam 1.0 52 (Hosted lines, for the Reflection API.)
- Security & auth, Gemini 4 Carbon +10: Gemini 4 Carbon 55 (Model reading for gemini-4-carbon on the Gemini API.); Beam 1.0 45 (Model reading.)
- Payments & pricing, Gemini 4 Carbon +10: Gemini 4 Carbon 20 (Model reading for gemini-4-carbon on the Gemini API.); Beam 1.0 10 (Graded on the Reflection API.)
