You can now filter dataset benchmark leaderboards by the number of model parameters. On any dataset leaderboard, pick a size range and the rankings refresh to that bucket. The top 3 models in each size category are marked with a 🏅.

Introducing Kernels

Kernels repositories provide an easy way to use kernels: precompiled, optimized for your exact hardware and PyTorch version, ready for torch.compile, and yields 1.7–2.5× speed-ups over baseline PyTorch.

You can now browse and load Kernels from the Kernels Hub.

Agent Traces on the Hub

You can now upload traces from your agents (Claude Code, Codex, Pi) directly to Hugging Face Datasets. The Hub auto-detects trace formats and tags your dataset as Traces, with a dedicated viewer for browsing sessions, turns, tool calls, and model responses.

No preprocessing needed, just upload the JSONL files from your local session directories as-is:

Agent Local session directory
Claude Code ~/.claude/projects
Codex ~/.codex/sessions
Pi ~/.pi/agent/sessions

Useful for sharing debugging workflows, benchmarking agent behavior across models, or building training data from real coding sessions.
