## Which one, for what

### Cerebras Inference (B)

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

Ahead on:
- Reliability, 70 against 15
- Schema & documentation, 93 against 51
- Agent ergonomics, 85 against 17
- Security & auth, 70 against 35
- Maintenance & community, 65 against 42
- Transparency & trust, 60 against 31

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

### Simplismart (F)

Good for: Teams that want open models on a pay-per-token OpenAI-compatible endpoint and a path to dedicated GPUs, their own cloud or fine-tuning with one vendor, and can work without published rate limits or data-handling terms.

Ahead on:
- Payments & pricing, 25 against 20

Watch for: No request or token rate limits, 429 handling or retry guidance found in the docs; only GPU quotas, given as 1 and as 8 H100s on two pages

## 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.

**Simplismart.** Simplismart exposes open models through an OpenAI-compatible endpoint with public per-token prices and expiring, revocable keys. Its public docs give no request rate limits, status page, retry guidance, tool-calling or structured-output reference, and its terms and privacy policy cover the website, not API data.

## 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.

### Simplismart

1. Point an OpenAI-compatible client at https://api.simplismart.live with SIMPLISMART_API_KEY as a Bearer token, and take model ids from the marketplace or the per-model API pages.
2. Set a key expiry and rotate before midnight UTC on the expiry date, because an expired key returns 401.
3. Cap retries yourself with exponential backoff, because no rate limits, 429 format or retry guidance are published.
4. Check that a model supports tools or JSON output with a test call before relying on it, because neither is documented.
5. Confirm the per-token price of the exact model in the console before running large jobs, because the public price list is incomplete.
