May 2025 performance highlights: Key features delivered: Implemented automated Community Labeling workflows across seven repositories (tt-kmd, luwen, tt-umd, tt-exalens, tt-tvm, tt-forge, tt-llk) by adopting a centralized labeling action from tenstorrent/tt-github-actions, including relocation for stability, naming adjustments, and reliability fixes to ensure proper triggering. Major bugs fixed: Stabilized labeling by addressing misplacements and misconfigurations via targeted reverts and path corrections to restore correct labeling behavior across all affected repos. Overall impact and accomplishments: Accelerated issue triage, improved contributor onboarding, and consistent labeling across communities, reducing manual overhead and enabling faster community contributions. Technologies/skills demonstrated: GitHub Actions and reusable workflows; cross-repo automation and CI/CD discipline; abi3 compatibility for Python 3.11+ in pyluwen; ProtoBuf build improvements to prefer system protoc, reducing vendored dependencies.

In March 2025, the development team's focus was on clarifying Tenstorrent's licensing posture across the product portfolio through a broad, cross-repo documentation effort. The team implemented a standardized LICENSE_understanding.txt across 11 repositories, establishing consistent guidance on software usage, hardware, models, and IP licensing. This proactive policy documentation reduces legal ambiguity, accelerates developer onboarding, and reinforces responsible product usage for customers and partners. There were no high-severity bug fixes; the month emphasized policy clarity, transparency, and governance alignment.
