Verdicts

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.

MiniMax API

M3.1 Flash costs $0.15 in and $0.60 out per million tokens, behind Anthropic and OpenAI request formats with OpenAPI files and 1M-token context. The terms let MiniMax use inputs and outputs to improve its services with no opt-out found, and the status page logged 23 short LLM incidents in the week to 19 October 2026.

Before you call either

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

MiniMax API

  1. Use the Anthropic-format base URL https://api.minimax.io/anthropic for tool calls. The OpenAI-format schema has no tool_choice or response_format
  2. Set output_config.effort (or reasoning_effort) below max for routine calls. M3.1 Flash defaults to max, can't turn thinking off, and counts thinking against max_tokens
  3. Don't rely on stop_sequences or top_k. The Anthropic-format endpoint ignores them
  4. Back off on 429 and 529 yourself. No Retry-After header is documented
  5. Use a pay-as-you-go key for production. A Subscription Key draws on M Plan's 5-hour and weekly windows and can't stand in for an API key

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
