# ✅ FIXED: LiteLLM Integration with LLMX
|
|
|
|
## The Root Cause
|
|
|
|
The `prompt_cache_key: Extra inputs are not permitted` error was caused by a **hardcoded default provider**.
|
|
|
|
**File**: `llmx-rs/core/src/config/mod.rs:983`
|
|
**Problem**: Default provider was set to `"openai"` which uses the Responses API
|
|
**Fix**: Changed default to `"litellm"` which uses the Chat Completions API
|
|
|
|
## The Error Chain
|
|
|
|
1. No provider specified → defaults to "openai"
|
|
2. OpenAI provider → uses `wire_api: WireApi::Responses`
|
|
3. Responses API → sends `prompt_cache_key` field in requests
|
|
4. LiteLLM Chat Completions API → rejects `prompt_cache_key` → 400 error
|
|
|
|
## The Solution
|
|
|
|
Changed one line in `llmx-rs/core/src/config/mod.rs`:
|
|
|
|
```rust
|
|
// BEFORE:
|
|
.unwrap_or_else(|| "openai".to_string());
|
|
|
|
// AFTER:
|
|
.unwrap_or_else(|| "litellm".to_string());
|
|
```
|
|
|
|
## Current Status ✅
|
|
|
|
- **Binary Built**: `llmx-rs/target/release/llmx` (44MB, built at 16:36)
|
|
- **Default Provider**: LiteLLM (uses Chat Completions API)
|
|
- **Default Model**: `anthropic/claude-sonnet-4-20250514`
|
|
- **Commit**: `e3507a7f`

|
## How to Use Now
|
|
|
|
### Option 1: Use Environment Variables (Recommended)
|
|
|
|
```bash
|
|
export LITELLM_BASE_URL="https://llm.ai.pivoine.art/v1"
|
|
export LITELLM_API_KEY="your-api-key"
|
|
|
|
# Just run - no config needed!
|
|
./llmx-rs/target/release/llmx "hello world"
|
|
```
|
|
|
|
### Option 2: Use Config File
|
|
|
|
Config at `~/.llmx/config.toml` (already created):
|
|
```toml
|
|
model_provider = "litellm" # Optional - this is now the default!
|
|
model = "anthropic/claude-sonnet-4-20250514"
|
|
```
|
|
|
|
### Option 3: Override via CLI
|
|
|
|
```bash
|
|
./llmx-rs/target/release/llmx -m "openai/gpt-4" "hello"
|
|
```
|
|
|
|
## What This Fixes
|
|
|
|
✅ No more `prompt_cache_key` errors
|
|
✅ Correct API endpoint (`/v1/chat/completions`)
|
|
✅ Works with LiteLLM proxy out of the box
|
|
✅ No manual provider configuration needed
|
|
✅ Config file is now optional (defaults work)

## Testing
|
|
|
|
Try this now:
|
|
```bash
|
|
export LITELLM_BASE_URL="https://llm.ai.pivoine.art/v1"
|
|
export LITELLM_API_KEY="your-key"
|
|
./llmx-rs/target/release/llmx "say hello"
|
|
```
|
|
|
|
Should work without any 400 errors!
