## Which one, for what

### DeepInfra (B)

Good for: Agents that want many open-weight models, embeddings, image and speech behind one OpenAI-style key at low per-token prices, with spend-capped tokens.

Ahead on:
- Reliability, 70 against 40

Watch for: A deprecated model gets at least one week's notice, and requests are then forwarded to a replacement model under the old id

### Gemini Developer API (B)

Good for: Cheap, long-context Flash calls for prototypes, public data and agents that need to start without a card.

Ahead on:
- Schema & documentation, 85 against 69
- Agent ergonomics, 90 against 77
- Payments & pricing, 40 against 20
- Maintenance & community, 83 against 65
- Transparency & trust, 72 against 67

Also in its favour:
- Free to start without a card

Watch for: Free-tier prompts and responses improve Google products and may be read by human reviewers

## Verdicts

**DeepInfra.** The model list, context sizes and per-token prices are readable without a key, and keys can carry an IP allowlist, a monthly spending cap and model-limited JWTs. Deprecated models get one week's notice and are then redirected to another model, there is no changelog or SLA, and an account needs a card or prepayment before any call.

**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.

## Before you call either

### DeepInfra

1. Call `GET https://api.deepinfra.com/v1/openai/models` at start-up for ids, context sizes and prices. No key is needed
2. Check the `model` field of each response. After a deprecation date, requests to the old id are served by a replacement model
3. Ask the account owner for a scoped JWT limited to the models and spend the task needs, not the full API key
4. Stay under 200 concurrent requests per model. On 429 `engine_overloaded`, retry after a delay, or send `models` with up to four fallbacks
5. Never inspect a JWT with `GET /v1/scoped-jwt?jwtoken=`, which puts the token in the URL. Keep credentials in the `Authorization` header

### Gemini Developer API

1. Never send customer data through a free-tier key. Link billing first
2. Don't request Gemini 4 Argon here. It has no Developer API model ID as of 5 October 2026
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
