feat: add MiniMax as a new LLM provider

[octo-patch]

Summary

• Add MiniMax as a new LLM provider with OpenAI-compatible API support
• Register MiniMax-M2.5 (204K context) and MiniMax-M2.5-highspeed models
• Include GUI model selection, provider configuration, and documentation

Changes

New Files

• core/llm/llms/MiniMax.ts — Provider class extending OpenAI with:
  • Temperature clamping to (0, 1] range (MiniMax rejects 0)
  • response_format removal (unsupported)
  • Default API base: https://api.minimax.io/v1/
• packages/llm-info/src/providers/minimax.ts — Model metadata
• docs/customize/model-providers/more/minimax.mdx — Provider documentation

Modified Files

• core/llm/llms/index.ts — Register in LLMClasses
• packages/openai-adapters/src/index.ts — Register OpenAI-compatible adapter
• packages/config-types/src/index.ts — Add "minimax" to provider enum
• packages/llm-info/src/index.ts — Add to allModelProviders
• gui/src/pages/AddNewModel/configs/models.ts — Model entries
• gui/src/pages/AddNewModel/configs/providers.ts — Provider config with API key setup
• docs/customize/model-providers/overview.mdx — Add to hosted services table

Models

Model	Context	Max Output	Description
MiniMax-M2.5	204,800	192,000	Peak performance, complex reasoning
MiniMax-M2.5-highspeed	204,800	192,000	Same performance, lower latency

Test Plan

• Verified MiniMax API connectivity and response format
• Verified temperature constraint handling
• Code follows existing provider patterns (Groq, DeepSeek, Mistral)

Summary by cubic

Add MiniMax as an OpenAI-compatible provider with GUI and docs, including MiniMax-M2.5 and MiniMax-M2.5-highspeed (204K context). Adds a dedicated MiniMaxApi adapter to enforce MiniMax-specific request rules.

• New Features

  • New minimax provider using https://api.minimax.io/v1/ via a dedicated MiniMaxApi (OpenAI-compatible) with temperature clamping and response_format removal.
  • Registers provider and models in LLMClasses, config types, and llm-info.
  • GUI: provider setup with API key and model entries for MiniMax-M2.5 and MiniMax-M2.5-highspeed.
  • Docs: provider guide and overview entry.

• Migration

  • Configure provider: minimax with your API key, or set MINIMAX_API_KEY.
  • For China, set apiBase to https://api.minimaxi.com/v1/.

<violation number="1" location="packages/openai-adapters/src/index.ts:145">
P1: MiniMax is wired to generic `OpenAIApi`, which skips the repo’s MiniMax-specific request fixes (temperature clamping and `response_format` removal), creating a real incompatibility path in adapter-based runtime flows.</violation>
