Which one, for what

Cloudflare AI Gateway B

Good for Teams that already hold a Cloudflare account and want one token, one bill, logs, budgets and fallbacks in front of several model providers, or that want to keep their own provider keys behind a proxy with spend limits.

Ahead on

  • Reliability, 66 against 50
  • Security & auth, 75 against 66
  • Payments & pricing, 52 against 40

Watch for

API tokens are account-scoped. Any token with AI Gateway Run can send requests through every gateway in the account and spend its stored provider keys

Mistral AI API BB

Good 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

  • Schema & documentation, 93 against 75
  • Agent ergonomics, 91 against 73
  • Maintenance & community, 88 against 75
  • Transparency & trust, 80 against 73

Also in its favour

  • Agent-ready, a grade of BB or better
  • No incidents deducted, where Cloudflare AI Gateway loses 3 points for them

Watch for

Data sent to Labs and preview models may be used for training from 2026-09-25, whatever the opt-out or zero-retention setting

Verdicts

Cloudflare AI Gateway

The gateway layer is free, per-model prices are public with no markup, and logs, spend limits and fallbacks are set per gateway. API tokens cannot be limited to one gateway, the service terms take third-party models outside Cloudflare's DPA, no SLA names the product, and error codes changed on 6 October 2026 with same-day notice.

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 may be used for training from 2026-09-25, whatever the opt-out or zero-retention setting.

Before you call either

Cloudflare AI Gateway

  1. Use the REST API at api.cloudflare.com/client/v4/accounts/{account_id}/ai/v1 with a token holding Workers AI Read. A token with only an AI Gateway permission returns 401 with code 10000
  2. Send cf-aig-gateway-id on every Workers AI (@cf/) call and on dynamic routes. Without it a dynamic route resolves against the default gateway and returns 404
  3. Set cf-aig-collect-log: false or cf-aig-collect-log-payload: false on sensitive requests. Logging of prompts and responses is on by default
  4. Treat a 429 as a rate limit or a spent budget and a 401 with code 2009 as a rejected provider key. Do not retry a 2009
  5. Set byok_only on the gateway or send cf-aig-no-wholesale: true to stop a request without a provider key falling through to paid Unified Billing credits

Mistral AI API

  1. Stay off labs-* and preview models 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. Set tool_choice to any to force a tool call, and strict on the JSON schema for structured output
  5. Read docs.mistral.ai/openapi.yaml for the request shapes instead of guessing from OpenAI's
