Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
Discover, download and generate with open-source AI models for image, video and 3D.
Browse one of the largest public libraries of open-source image, video and 3D AI models, with ratings, reviews, example images and download counts on every model page.
Generate images, video and 3D assets in the browser using hosted versions of featured models, no local GPU or setup required.
Search, collect and organize checkpoints, LoRAs, embeddings and ControlNet models, then compare outputs side by side before committing to a workflow.
Join challenges, events and creator leaderboards, follow top artists, remix images and share your own models with the community.
