skamenan7 857496ea3e fix: Resolve Llama4 tool calling 500 errors (Issue #2584) ... This commit fixes the tool calling failures with Llama4 models that were returning 500 errors while Together API worked correctly. The root cause was that the system was using Llama3's JSON format for all models instead of Llama4's python_list format. Key changes: - NEW: llama_stack/models/llama/llama4/interface.py - Complete Llama4 interface with python_list tool format support - MODIFIED: prompt_adapter.py - Added model-aware decode_assistant_message() that uses Llama4ChatFormat for llama4 models and Llama3ChatFormat for others - MODIFIED: openai_compat.py - Updated to pass model_id parameter to enable model-specific format detection - MODIFIED: sku_list.py - Enhanced with provider alias support for better model resolution - NEW: tests/unit/models/test_decode_assistant_message.py - Comprehensive unit tests for the new decode_assistant_message function The fix ensures that: - Llama4 models (meta-llama/Llama-4-*) use python_list format: [func(args)] - Other models continue using JSON format: {"type": "function", ...} - Backward compatibility is maintained for existing models - Tool calling works correctly across different model families - Graceful fallback when Llama4 dependencies are unavailable Testing: - All 17 unit tests pass (9 original + 8 new) - Conditional imports prevent torch dependency issues - Comprehensive test coverage for different model types and scenarios Fixes #2584		2025-07-15 11:47:05 -04:00
