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

  • Reliability, 60 against 28
  • Schema & documentation, 90 against 62
  • Agent ergonomics, 95 against 72
  • Security & auth, 92 against 65
  • Maintenance & community, 91 against 62
  • Transparency & trust, 85 against 56

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

Novita AI D

Good for Agents that want many open-weight models at per-token prices behind one OpenAI-style key, with keys that can be limited by model, IP and expiry.

Ahead on

  • Payments & pricing, 35 against 30

Watch for

No status page or SLA was found on the home page, the docs index or the docs site map. The home page states 99.5% uptime with no supporting document

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.

Novita AI

Per-token prices for about 140 language models are public, and each key can carry an expiry, a model allowlist and a source IP allowlist. No status page, SLA or security.txt was found, the per-model rate limit figures are drawn by script, and both vendor SDK repositories are archived while the docs still point to them.

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

Novita AI

  1. Set the OpenAI client base URL to https://api.novita.ai/openai and send the key as Authorization: Bearer. Keys start with sk_
  2. Do not close a connection to stop generation. A request that reached the model is billed in full under status 499, so cap output with max_tokens
  3. On 429, check whether the code is RATE_LIMIT_EXCEEDED or TOKEN_LIMIT_EXCEEDED and back off exponentially. No Retry-After header is documented
  4. Read the changelog for retirement notices before pinning a model id. One retirement in October 2026 came with 11 days' notice
  5. Ask the account owner for a key with an expiry, a model access policy and an IP allowlist. Keys are created and deleted only in the console

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.
