What changed
Tracy Profiler 0.14 reworked Tracy Assist around modern llama.cpp integration, lets users attach captured call stacks and trace context to chats, and says small 4B local models can handle simple analysis tasks.
Why it matters
It brings model-assisted diagnosis closer to profiler-native evidence while allowing sensitive performance traces and source analysis to remain local.
What to do
Test it on a non-sensitive trace: attach one expensive or crashed call stack, request a falsifiable bottleneck hypothesis, then verify every claim against samples, zones, timings, and source.
Caveat
The 4B usability claim is qualitative and maintainer-reported; no accuracy, latency, privacy, or adversarial benchmark is published, and Tracy Assist still requires a user-managed local model setup.
