Feb 1, 2025February 2025 was focused on expanding model compatibility, stabilizing core functionality, and improving developer-facing documentation to accelerate deployment and reliability. Key work included enabling DeepSeek-R1-Distill-Qwen family models (1.5B, 7B, and 14B variants) and broad ModelExport support for llama3 and qwen2_vl families, along with templating updates to accommodate qwen2_vl and qwen2_5_vl. In addition, a series of robustness fixes improved chat and image handling, reduced TypeError occurrences, and enhanced overall system stability. These efforts enhance production readiness, enable broader model deployment, and reduce maintenance overhead.
