Jun 1, 2026June 2026 highlights for sophgo/LLM-TPU (Gemma4): focused on robustness and multi-modal support. Delivered two targeted changes: (1) a bug fix for Vision Transformer attention_mask handling in Gemma4, removing unnecessary pre-computation for bidirectional groups and ensuring correct masking on ViT tokens (commit b3d541bbc5273ec27a4cb13f5cfa8504140d75de); (2) a feature enabling per-layer token embeddings separation with an external embedding file to improve processing of multi-modal inputs (audio, video, text) (commit 95bc8c5ed7eba47a8e34a733f94a73f8ac6b3bdc). These updates enhance model correctness, flexibility, and readiness for broader multi-modal deployment.

Mar 1, 2025March 2025 focused on improving build stability and maintainability in the sophgo/LLM-TPU repository by gating the media processing pathway behind the ENABLE_MEDIA feature flag. This prevented build-time failures when media support is disabled and aligned with feature-flag driven development practices, reducing CI churn and easing future configuration changes.
