February 2026 focused on hardening the chat workflow in ggml-org/llama.cpp, with emphasis on Step-3.5-Flash parsing, separation of API reasoning content from outputs, and more robust tool-call handling. Implemented detection improvements for Step-3.5-Flash XML tool calls, introduced thinking_forced_open handling, and routed Step-3.5-Flash through the Nemotron v3 PEG parser for streaming and robust parameter parsing. Added a dedicated test suite validating basic messages, tool calls with/without thinking content, optional closing tags, and JSON schema responses to ensure robustness across input scenarios. Removed dead thinking code and aligned XML handling across Qwen3-Coder and Nemotron paths to reduce misrouting and improve reliability. This work reduces latency in API responses, improves correctness of reasoning separation, and lays groundwork for future feature work.
