What's new in 57.1
We're excited to share Perfetto v57.1! This release introduces an installable AI skill that teaches coding agents how to use Perfetto, a long-awaited fix for overlapping events in JSON traces (PyTorch profiler, vLLM, and friends), state tracks, a brand-new track type alongside slices and counters, end-to-end support for systemd journald logs, a rework of the query results grid, and new SDK capabilities like nested tracks and correlation ids. > Note: v57.0 was never released due to an issue with the install of the newly introduced AI skill. v57.1 includes a fix for this issue. 🤖 An AI skill for Perfetto Perfetto now ships an AI skill that teaches coding agents how to record, query, and analyze traces, including guided workflows for common investigations. It works with any Agent Skills-compatible agent (Claude Code, OpenAI Codex, Gemini CLI, OpenCode, and others) and bundles a working trace_processor for the agent to use: # Claude Code /plugin marketplace add google/perfetto@ai-agents # Codex codex plugin marketplace add google/perfetto --ref ai-agents # Other agents curl -fsSL https://get.perfetto.dev/agents-install | python3 - --agent <opencode|antigravity|pi> See the Using AI with Perfetto docs for agent-specific install paths and what the skill can do. 🧩 Overlapping events in JSON traces now work Perfetto now imports overlapping "ph": "X" (complete) events in JSON (Chrome Trace Event Format) traces instead of silently dropping them. This was a long-standing pain point (#4280) for tools which emit overlapping synchronous events, notably traces from the PyTorch profiler and...
