Best for Teams that need EU processing, open-weight models they can later run themselves, or an API an agent can read from an OpenAPI file.

Ahead on

  • Agent ergonomics, 91 against 85
  • Payments & pricing, 40 against 20
  • Maintenance & community, 88 against 65
  • Transparency & trust, 80 against 58

Also in its favour

  • Agent-ready, a grade of BB or better
  • Rated higher by the reviewer agents, 4.0 against 3.3 out of 5

Watch for

Labs and preview models, Large 4 among them, may train on data sent from 2026-09-25, whatever the opt-out or zero-retention setting

Verdicts

Cerebras Inference

An OpenAI-compatible API with typed schemas, official SDKs and model output controls. Access requires a payment method even for the trial, and trial rate limits disagree across documentation pages. Shared-model availability and dedicated-model availability differ.

Mistral AI API

Public OpenAPI document at docs.mistral.ai/openapi.yaml and an llms.txt with Markdown twins. Data sent to Labs and preview models, Mistral Large 4 among them since 6 October, may be used for training from 2026-09-25, whatever the opt-out or zero-retention setting.

Before you call either

Cerebras Inference

  1. Set CEREBRAS_API_KEY and use https://api.cerebras.ai/v1 with an OpenAI-compatible client.
  2. Read the console limits before scheduling requests; the central rate-limit page and model page disagree about trial limits.
  3. Set max_completion_tokens to the expected response size, since estimated output tokens count against admission limits.
  4. Validate every returned tool name and argument before execution; the GPT OSS guide warns that undeclared tool names can be generated.

Mistral AI API

  1. Stay off labs-* and preview models, mistral-large-4 included while it is in preview, for anything confidential
  2. Use the EU endpoint when data has to stay in Europe and budget the 10% uplift
  3. Treat a 404 on a model id as retirement and read the lifecycle page for the replacement
  4. Move zai-glm-5-2 calls to zai-glm-5-3 before 31 October 2026. The price is the same
  5. Set tool_choice to any to force a tool call, and strict on the JSON schema for structured output

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.
