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

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
