## Key Implementations Verified

### 1. Dynamic base_url Parameter (NEW in v2.6.5) ✅
```json
{
  "model": "openai-compatible/model-name",
  "base_url": "http://localhost:1234/v1",
  "messages": [...]
}
```
- **Implementation**: `abstractcore/server/app.py` (ChatCompletionRequest model)
- **Logging**: Custom base URLs logged with 🔗 emoji
- **Priority**: POST parameter > environment variable > provider default
- **Status**: **WORKING PERFECTLY**

### 2. Model Listing Fix (FIXED in v2.6.5) ✅
```python
if self.model == "default":
    return  # Skip validation for registry placeholder
```
- **Implementation**: `abstractcore/providers/openai_compatible_provider.py`
- **Result**: /v1/models endpoint now lists all 27 models
- **Status**: **WORKING PERFECTLY**

### 3. Registry Instance Provider (ENHANCED in v2.6.5) ✅
```python
if provider_name in ["anthropic", "ollama", "lmstudio", "openai-compatible"]:
```
- **Implementation**: `abstractcore/providers/registry.py`
- **Result**: Proper base_url injection from environment variables
- **Status**: **WORKING PERFECTLY**
