From 49d1390354380d54e597170b790845b1a904d2a8 Mon Sep 17 00:00:00 2001 From: octo-patch Date: Tue, 24 Mar 2026 17:34:04 +0800 Subject: [PATCH] feat: add MiniMax as first-class LLM provider Add MiniMax M2.7 and M2.7-highspeed models to PaperDebugger's model registry with full OpenAI-compatible API support. Models are available via OpenRouter (default) and optionally via direct MiniMax API when MINIMAX_API_KEY is configured. Changes: - Add MiniMax M2.7/M2.7-highspeed to allModels registry (1M context, 128K output) - Add MINIMAX_API_KEY/MINIMAX_BASE_URL env var config - Route MiniMax models to MiniMax API when server key is configured - Temperature clamping for MiniMax models (max 1.0) - Set model name on LLMProviderConfig for provider-aware routing - Update README and DEVELOPMENT.md with MiniMax documentation - 27 unit tests + 4 integration tests across 5 test files --- README.md | 2 +- docs/DEVELOPMENT.md | 14 ++ internal/api/chat/list_supported_models_v2.go | 31 ++++ .../api/chat/list_supported_models_v2_test.go | 130 ++++++++++++++++ internal/libs/cfg/cfg.go | 13 ++ internal/libs/cfg/minimax_cfg_test.go | 44 ++++++ internal/models/llm_provider.go | 7 + internal/models/llm_provider_test.go | 53 +++++++ internal/services/toolkit/client/client_v2.go | 7 +- .../services/toolkit/client/completion_v2.go | 2 + .../client/minimax_integration_test.go | 104 +++++++++++++ .../toolkit/client/minimax_params_test.go | 105 +++++++++++++ .../toolkit/client/minimax_routing_test.go | 143 ++++++++++++++++++ internal/services/toolkit/client/utils_v2.go | 9 +- 14 files changed, 661 insertions(+), 3 deletions(-) create mode 100644 internal/api/chat/list_supported_models_v2_test.go create mode 100644 internal/libs/cfg/minimax_cfg_test.go create mode 100644 internal/models/llm_provider_test.go create mode 100644 internal/services/toolkit/client/minimax_integration_test.go create mode 100644 internal/services/toolkit/client/minimax_params_test.go create mode 100644 internal/services/toolkit/client/minimax_routing_test.go diff --git a/README.md b/README.md index 26088813..2a84877b 100644 --- a/README.md +++ b/README.md @@ -96,7 +96,7 @@ The PaperDebugger backend is built with modern technologies: - **Language**: Go 1.24+ - **Framework**: Gin (HTTP) + gRPC (API) - **Database**: MongoDB -- **AI Integration**: OpenAI API +- **AI Integration**: OpenAI API, [MiniMax](https://www.minimaxi.com/) (via OpenAI-compatible API) - **Architecture**: Microservices with Protocol Buffers - **Authentication**: JWT-based with OAuth support diff --git a/docs/DEVELOPMENT.md b/docs/DEVELOPMENT.md index 4d9959bf..181362b4 100644 --- a/docs/DEVELOPMENT.md +++ b/docs/DEVELOPMENT.md @@ -46,6 +46,20 @@ cp .env.example .env # Edit the .env file based on your configuration ``` +**Required environment variables:** +| Variable | Description | +|---|---| +| `OPENAI_API_KEY` | OpenAI API key (server-side default) | +| `OPENAI_BASE_URL` | OpenAI base URL (default: `https://api.openai.com/v1`) | +| `INFERENCE_API_KEY` | OpenRouter inference API key | +| `INFERENCE_BASE_URL` | Inference endpoint URL | + +**Optional provider keys (for direct API access):** +| Variable | Description | +|---|---| +| `MINIMAX_API_KEY` | [MiniMax](https://www.minimaxi.com/) API key for direct access to MiniMax models (M2.7, M2.7-highspeed) | +| `MINIMAX_BASE_URL` | MiniMax base URL (default: `https://api.minimax.io/v1`) | + #### 4.
