The docs mark Gemma 4 31B as request access per organisation, while llms.txt and the keyless catalogue list it as available\n\n\n## Score by category\n\n| Category | Weight | MiniMax API | Prism Inference | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 75 | 65 | MiniMax API +10 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 82 | 82 | even |\n| Agent ergonomics | 13% (16.2 this run) | 59 | 68 | Prism Inference +9 |\n| Security \u0026 auth | 14% (17.5 this run) | 30 | 65 | Prism Inference +35 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 30 | Prism Inference +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 45 | 49 | Prism Inference +4 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 64 | 61 | MiniMax API +3 |\n| Negative events | ≤15 | 0 | -2 | |\n| **Total** | | **55.2 · C** | **60.1 · C** | |\n\n## Facts side by side\n\n| Fact | MiniMax API | Prism Inference |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | MiniMax | Prism Technologies Inc |\n| Hosted endpoint | `https://api.minimax.io` | `https://api.prisminference.com/v1` |\n| Transports | HTTP | HTTP |\n| Auth | API key | API key |\n| Pricing | Pay per use | Pay per use |\n| x402 | no | no |\n| Licence | Proprietary API under MiniMax's platform terms.

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.\n\n**Prism Inference.** Three wire formats, a public OpenAPI 3.1 file, per-token prices in a keyless catalogue and zero data retention by default on every tier. The service launched on 24 September 2026 with two models, one of them by request, from a two-person company. No rate-limit numbers, SLA document, free tier or deprecation policy was found.\n\n## Before you call either\n\n### MiniMax API\n\n1. 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`\n2. 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`\n3. Don't rely on `stop_sequences` or `top_k`. The Anthropic-format endpoint ignores them\n4. Back off on 429 and 529 yourself. No Retry-After header is documented\n5. 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\n\n### Prism Inference\n\n1. Call `GET https://api.prisminference.com/v1/models` at start-up, with no key, and use only ids it returns. Expect 403 on `gemma-4-31b` without organisation access\n2. Use base URL `https://api.prisminference.com/v1` for OpenAI clients and `https://api.prisminference.com` with no `/v1` for Anthropic clients\n3. Read `error.retryable` before retrying, and wait for `Retry-After` on 429, which covers both key limits and model capacity\n4. Send `reasoning_effort: \"none\"` or `low` when latency matters. Reasoning is on by default and its tokens are billed as output\n5. Keep conversation state yourself and send `store: false` on Responses. `previous_response_id`, stored responses and hosted tools aren't supported\n\n## Questions\n\n### Which is better for AI agents, MiniMax API or Prism Inference?\n\nPrism Inference scores 60.1 (C) on agent readiness against MiniMax API's 55.2 (C), and leads in 4 of 7 scored categories. MiniMax API leads on reliability.\n\n### Do MiniMax API and Prism Inference need an API key?\n\nBoth need an API key.\n\n### Can an agent call MiniMax API and Prism Inference without installing anything?\n\nYes. MiniMax API has a hosted endpoint at https://api.minimax.io and Prism Inference at https://api.prisminference.com/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/minimax-api-vs-prism-inference.json, and with the fewest tokens: https://www.anchorterminal.com/compare/minimax-api-vs-prism-inference.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"minimax-api\", \"b\": \"prism-inference\"}`.
