Which one, for what

Cerebras Inference B

Best for Cerebras Inference serves language models on Cerebras wafer-scale processors through an OpenAI-compatible API.

Ahead on

  • Schema & documentation, 93 against 75
  • Agent ergonomics, 85 against 73

Also in its favour

  • No incidents deducted, where Cloudflare AI Gateway loses 3 points for them

Watch for

Trial access requires a verified payment method and ends after $5 or 30 days

Cloudflare AI Gateway B

Best 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

  • Security & auth, 75 against 70
  • Payments & pricing, 52 against 20
  • Maintenance & community, 75 against 65
  • Transparency & trust, 73 against 58

Watch for

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.

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.

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.

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
