- Claude Fable 5.2, good for Agents doing long, hard work (large coding changes, multi-step research, computer use) that can pay frontier prices, accept 30-day retention and don't need to force a tool call. Ahead on Reliability, 60 against 30; Schema & documentation, 90 against 70; Agent ergonomics, 95 against 62; Security & auth, 92 against 57; Payments & pricing, 30 against 20; Maintenance & community, 91 against 75; Transparency & trust, 85 against 64. Also Agent-ready, a grade of BB or better.
- 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:
- Security & auth, Claude Fable 5.2 +35: Claude Fable 5.2 92 (Model reading for claude-fable-5-2 on the Claude API.); Inkling 2 Small 57 (Platform readings are the tinker listing's.)
- Agent ergonomics, Claude Fable 5.2 +33: Claude Fable 5.2 95 (Model reading for claude-fable-5-2 on the Claude API.); Inkling 2 Small 62 (Model reading (tool use, structured output, caching, context, batch, SDKs).)
- Reliability, Claude Fable 5.2 +30: Claude Fable 5.2 60 (Model reading for claude-fable-5-2 on the Claude API.); Inkling 2 Small 30 (Model reading, for the surface it's called on, Tinker's serverless inference and OpenAI-compatible API.)
- Transparency & trust, Claude Fable 5.2 +21: Claude Fable 5.2 85 (Model reading for claude-fable-5-2 on the Claude API.); Inkling 2 Small 64 (Editorial half.)
- Schema & documentation, Claude Fable 5.2 +20: Claude Fable 5.2 90 (Model reading for claude-fable-5-2 on the Claude API.); Inkling 2 Small 70 (Model reading.)
- Maintenance & community, Claude Fable 5.2 +16: Claude Fable 5.2 91 (Model reading for claude-fable-5-2 on the Claude API.); Inkling 2 Small 75 (Model reading.)
