Oct 1, 2025October 2025 (quic/efficient-transformers): Focused on expanding and stabilizing multimodal vision-language model (VLM) capabilities across PyTorch and ONNX Runtime, broadening model compatibility, and improving reliability for scalable production deployment. Key work includes multi-image inference support, improved head_dim handling, and enabling newer model series (InternVL_3_5 and Qwen3ForCausalLM) with robust vision embedding processing. CI validation covered Qwen3-0.6B, and input handling was hardened for dual QPC configurations.
