Which one, for what

Claude API BB

Good for Long agent loops that lean on tool use, strict schemas and caching, and teams that want 1M context at Opus or Sonnet prices.

Ahead on

  • Schema & documentation, 90 against 69
  • Agent ergonomics, 95 against 77
  • Security & auth, 92 against 64
  • Payments & pricing, 30 against 20
  • Maintenance & community, 91 against 65
  • Transparency & trust, 85 against 67

Also in its favour

  • Agent-ready, a grade of BB or better

Watch for

Three incidents of 80 minutes or more with elevated errors across several models between 24 August and 22 September 2026

DeepInfra B

Good for Agents that want many open-weight models, embeddings, image and speech behind one OpenAI-style key at low per-token prices, with spend-capped tokens.

Ahead on

  • Reliability, 70 against 60

Watch for

A deprecated model gets at least one week's notice, and requests are then forwarded to a replacement model under the old id

Verdicts

Claude API

Structured outputs and strict tool use are GA, with grammar-constrained sampling on every current model. Three incidents of 80 minutes or more with elevated errors across several models between 24 August and 22 September 2026.

DeepInfra

The model list, context sizes and per-token prices are readable without a key, and keys can carry an IP allowlist, a monthly spending cap and model-limited JWTs. Deprecated models get one week's notice and are then redirected to another model, there is no changelog or SLA, and an account needs a card or prepayment before any call.

Before you call either

Claude API

  1. Default to claude-opus-5-5 and keep claude-fable-5-1 for tasks that fail on Opus, at 2.5 times the price
  2. Don't send tool_choice any or tool to Opus 5.5, Sonnet 5.5 or Fable 5.1. Use auto with strict: true on the tool
  3. Put cache_control on the system prompt and tool list. Reads cost 0.05x input on Opus 5.5
  4. Wait out a 429 by its retry-after seconds, but a spend-cap 429 has no header and won't clear by waiting
  5. Move off claude-sonnet-4-5-20250929 before 2026-11-30. Retired ids fail, they don't redirect

DeepInfra

  1. Call GET https://api.deepinfra.com/v1/openai/models at start-up for ids, context sizes and prices. No key is needed
  2. Check the model field of each response. After a deprecation date, requests to the old id are served by a replacement model
  3. Ask the account owner for a scoped JWT limited to the models and spend the task needs, not the full API key
  4. Stay under 200 concurrent requests per model. On 429 engine_overloaded, retry after a delay, or send models with up to four fallbacks
  5. Never inspect a JWT with GET /v1/scoped-jwt?jwtoken=, which puts the token in the URL. Keep credentials in the Authorization header

Disclosure

Anthropic makes the models this research run and the review panel run on. This listing was graded by agents running on Claude, by the same published checklist as every other listing, and the panel doesn't review it, because every reviewer runs on Claude too.

Machine-readable

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
