# LLMX with LiteLLM Configuration Guide
|
|
|
|
## Quick Start
|
|
|
|
### 1. Set Environment Variables
|
|
|
|
```bash
|
|
export LLMX_BASE_URL="https://llm.ai.pivoine.art/v1"
|
|
export LLMX_API_KEY="your-litellm-master-key"
|
|
```
|
|
|
|
### 2. Create Configuration File
|
|
|
|
Create `~/.llmx/config.toml`:
|
|
|
|
```toml
|
|
model_provider = "litellm"
|
|
model = "anthropic/claude-sonnet-4-20250514"
|
|
```
|
|
|
|
### 3. Run LLMX
|
|
|
|
```bash
|
|
# Use default config
|
|
llmx "hello world"
|
|
|
|
# Override model
|
|
llmx -m "openai/gpt-4" "hello world"
|
|
|
|
# Override provider and model
|
|
llmx -c model_provider=litellm -m "anthropic/claude-sonnet-4-20250514" "hello"
|
|
```
|
|
|
|
## Important Notes
|
|
|
|
### DO NOT use provider prefix in model name
|
|
|
|
❌ Wrong: `llmx -m "litellm:anthropic/claude-sonnet-4-20250514"`
|
|
✅ Correct: `llmx -c model_provider=litellm -m "anthropic/claude-sonnet-4-20250514"`
|
|
|
|
LLMX uses separate provider and model parameters, not a combined `provider:model` syntax.
|
|
|
|
### Provider Selection
|
|
|
|
The provider determines which API endpoint and format to use:
|
|
|
|
- `litellm` → Uses Chat Completions API (`/v1/chat/completions`)
|
|
- `openai` → Uses Responses API (`/v1/responses`) - NOT compatible with LiteLLM
|
|
|
|
### Model Names
|
|
|
|
LiteLLM uses `provider/model` format:
|
|
|
|
- `anthropic/claude-sonnet-4-20250514`
|
|
- `openai/gpt-4`
|
|
- `openai/gpt-4o`
|
|
|
|
Check your LiteLLM configuration for available models.
|
|
|
|
## Troubleshooting
|
|
|
|
### Error: "prompt_cache_key: Extra inputs are not permitted"
|
|
|
|
**Cause**: Using wrong provider (defaults to OpenAI which uses Responses API)
|
|
**Fix**: Add `-c model_provider=litellm` or set `model_provider = "litellm"` in config
|
|
|
|
### Error: "Invalid model name passed in model=litellm:..."
|
|
|
|
**Cause**: Including provider prefix in model name
|
|
**Fix**: Remove the `litellm:` prefix, use just the model name
|
|
|
|
### Error: "Model provider `litellm` not found"
|
|
|
|
**Cause**: Using old binary without LiteLLM provider
|
|
**Fix**: Use the newly built binary at `llmx-rs/target/release/llmx`
|
|
|
|
## Binary Location
|
|
|
|
Latest binary with LiteLLM support:
|
|
|
|
```
|
|
/home/valknar/Projects/llmx/llmx/llmx-rs/target/release/llmx
|
