Month: 2025-11 — Across three repositories (tenstorrent/tt-forge-models, tenstorrent/tt-xla, tenstorrent/tt-forge), delivered a cohesive set of model bring-ups, robust inference pipelines, and scalable configuration improvements that advance reliability, performance, and experimentation velocity. Key features were delivered across DETR model loaders, end-to-end Arnold DQN RL in ViZDoom, Llama 3.2 Vision for VQA, and extensive inference-server enhancements (pre/post-processing, input/output normalization, and memory-conscious configurations). These efforts broaden model coverage, stabilize deployments, and provide reusable patterns for future model bring-ups, enabling faster validation and safer production rollouts.
