Verdicts

Cloudflare Workers AI

Per-model prices, rate limits and JSON Schemas are public, 10,000 neurons a day are free, and x402 payment is in beta on /ai/run for four models. No SLA was found, three models moved to paid-only access on 28 July 2026 with no notice, and several docs pages still use a model retired in May.

GroqCloud

Free plan with no card, at 30 requests a minute and 1,000 a day on gpt-oss. Four model shutdown dates between 2026-07-17 and 2026-09-21, with no stated minimum notice.

Before you call either

Cloudflare Workers AI

  1. Check the model page before calling. Seven models need Workers Paid or AI Gateway credits and return 403 with code 5035 on the Free plan
  2. Read the internal code on a 429. 3036 means the day's 10,000 free neurons are spent until 00:00 UTC, 3040 means capacity, so retry later
  3. Set options.rejectIfBusy to fail fast, or add ?queueRequest=true for the batch route when the answer can wait
  4. Send the same x-session-affinity value on every turn of a session to reach the prefix cache and the cached-input price
  5. Keep paid frontier models under 20 requests a minute per model, or 50 with prepaid AI Gateway credits

GroqCloud

  1. Call /models at start-up. Four model ids stopped working this quarter
  2. Read retry-after on a 429 and the x-ratelimit-remaining-tokens header before the next call
  3. Free plan allows 8,000 tokens a minute on gpt-oss, so keep prompts small or batch them
  4. Don't build on Qwen 3.8 27B. It's a preview and previews can go at short notice
  5. Treat a 498 as Flex capacity and retry later; 5xx responses aren't billed
