Gemini 4 Carbon scores 62.6 (B) on agent readiness against Inkling 2 Small's 52.1 (D), and leads in 5 of 7 scored categories. Both do llm inference.

- Gemini 4 Carbon: B 62.6, rank #555 of 1518 · https://www.anchorterminal.com/tools/gemini-4-carbon.min.md
- Inkling 2 Small: D 52.1, rank #1004 of 1518 · https://www.anchorterminal.com/tools/inkling-2-small.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 Reliability, 40 against 30; Schema & documentation, 85 against 70; Agent ergonomics, 93 against 62; Maintenance & community, 83 against 75; Transparency & trust, 72 against 64.
- Inkling 2 Small, good for Developers who want a capable multimodal open-family model through an OpenAI-compatible API today, or to fine-tune it on Tinker, and who can live with a beta surface until the weights are published.

Why the edge:
- Agent ergonomics, Gemini 4 Carbon +31: Gemini 4 Carbon 93 (Model reading for gemini-4-carbon on the Gemini API.); Inkling 2 Small 62 (Model reading (tool use, structured output, caching, context, batch, SDKs).)
- Schema & documentation, Gemini 4 Carbon +15: Gemini 4 Carbon 85 (Model reading for gemini-4-carbon on the Gemini API.); Inkling 2 Small 70 (Model reading.)
- Reliability, Gemini 4 Carbon +10: Gemini 4 Carbon 40 (Model reading for gemini-4-carbon on the Gemini API.); Inkling 2 Small 30 (Model reading, for the surface it's called on, Tinker's serverless inference and OpenAI-compatible API.)
- Maintenance & community, Gemini 4 Carbon +8: Gemini 4 Carbon 83 (Model reading for gemini-4-carbon on the Gemini API.); Inkling 2 Small 75 (Model reading.)
- Transparency & trust, Gemini 4 Carbon +8: Gemini 4 Carbon 72 (Model reading for gemini-4-carbon on the Gemini API.); Inkling 2 Small 64 (Editorial half.)
