Claude Code Proxy - NVIDIA NIM Implementation
|
|
|
|
This server acts as a robust proxy between Anthropic API requests and NVIDIA NIM,
|
|
enabling Claude Code CLI to utilize NIM models with full support for:
|
|
- Streaming with SSE (Server-Sent Events)
|
|
- Thinking/Reasoning blocks and Reasoning-Split mode
|
|
- Native and heuristic tool use parsing
|
|
- Automatic model mapping (Haiku/Sonnet/Opus to NIM equivalents)
|
|
- Fast prefix detection for CLI policy specifications
