## Verdicts

**Gemini Developer API.** Free tier on 3.8 Flash and Flash-Lite with no billing account. Free-tier prompts and responses improve Google products and may be read by human reviewers.

**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

### Gemini Developer API

1. Never send customer data through a free-tier key. Link billing first
2. Budget 3.8 Flash at $1.50/$7.50 from 2027-01-01, not the introductory price
3. Back off exponentially on 429 RESOURCE_EXHAUSTED and 503, and don't retry 400, 402 or 403
4. Stop sending temperature, top_p and top_k. They've been deprecated since 2026-07-21
5. Validate structured output yourself. The docs don't promise schema-constrained decoding

### 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
