## Which one, for what

### DeepSeek API (E)

Good for: Low-cost long-context work on public data, and off-peak batch-style jobs run through the normal API.

Ahead on:
- Reliability, 60 against 15
- Agent ergonomics, 70 against 17
- Transparency & trust, 65 against 31

Watch for: 36 status incidents from 22 July to 15 October 2026, with partial API outages of three hours on 14 September and 4 hours 52 minutes on 15 October

### 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:
- Security & auth, 35 against 30
- Payments & pricing, 25 against 20

Also in its favour:
- No incidents deducted, where DeepSeek API loses 3 points for them

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

**DeepSeek API.** Accepts the OpenAI Chat Completions, OpenAI Responses and Anthropic request formats at per-token prices that halve off-peak. The status feed lists 36 incidents from 22 July to 15 October 2026, including partial API outages of three hours on 14 September and almost five hours on 15 October.

**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

### DeepSeek API

1. Send only data you'd be happy to publish
2. Schedule bulk work off-peak for half price. Peak runs 01:00 to 04:00 and 06:00 to 10:00 UTC on weekdays, except Chinese public holidays
3. Set `max_tokens` yourself. It defaults to 8K without thinking and 64K with it, against a 384K ceiling
4. For schema-checked tool arguments use base URL `https://api.deepseek.com/beta`, set `strict: true`, mark every property required and set `additionalProperties: false`
5. Keep a fallback provider and re-run evals after model changes. 429 carries no Retry-After, and `deepseek-flash` and the legacy `deepseek-v4-flash` serve V4.1-Flash-1017 since 17 October 2026

### 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.
