## Which one, for what

### GroqCloud (BB)

Good for: Many small, latency-sensitive calls on open-weight models, routing, extraction and classification, and agents that need to start free.

Ahead on:
- Reliability, 100 against 65
- Agent ergonomics, 80 against 68
- Security & auth, 77 against 65
- Payments & pricing, 40 against 30
- Maintenance & community, 72 against 49
- Transparency & trust, 85 against 61

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

Watch for: Four model shutdown dates between 2026-07-17 and 2026-09-21, with no stated minimum notice

### Prism Inference (C)

Good for: Coding agents that want DeepSeek-V4.1-Flash at a low input price, with no retention, through whichever of the three wire formats the harness already speaks.

Ahead on:
- Schema & documentation, 82 against 64

Watch for: Two models. The docs mark Gemma 4 31B as request access per organisation, while llms.txt and the keyless catalogue list it as available

## Verdicts

**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.

**Prism Inference.** Three wire formats, a public OpenAPI 3.1 file, per-token prices in a keyless catalogue and zero data retention by default on every tier. The service launched on 24 September 2026 with two models, one of them by request, from a two-person company. No rate-limit numbers, SLA document, free tier or deprecation policy was found.

## Before you call either

### 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

### Prism Inference

1. Call `GET https://api.prisminference.com/v1/models` at start-up, with no key, and use only ids it returns. Expect 403 on `gemma-4-31b` without organisation access
2. Use base URL `https://api.prisminference.com/v1` for OpenAI clients and `https://api.prisminference.com` with no `/v1` for Anthropic clients
3. Read `error.retryable` before retrying, and wait for `Retry-After` on 429, which covers both key limits and model capacity
4. Send `reasoning_effort: "none"` or `low` when latency matters. Reasoning is on by default and its tokens are billed as output
5. Keep conversation state yourself and send `store: false` on Responses. `previous_response_id`, stored responses and hosted tools aren't supported
