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.
The open platform where the machine learning community hosts models, datasets, and AI apps
Search, download, and publish across millions of models and hundreds of thousands of datasets, complete with model cards, versioning, and citations.
Deploy Gradio, Streamlit, or static apps directly from a repository to show off a model, run comparisons, or share a tool with a public link.
Transformers, Diffusers, Datasets, Tokenizers, Accelerate, PEFT, TRL, and smolagents give you end-to-end tooling for training, fine-tuning, and inference.
Inference Providers route a single API to tens of thousands of models from multiple vendors, while Inference Endpoints spin up dedicated GPU hardware on demand.
SpecialistA unified API gateway routing requests across hundreds of language models, but lacking dataset hosting.

Delivers ultra-fast serverless inference for open-weight models, prioritizing production throughput over community dataset sharing.
Provides low-cost serverless inference and GPU rentals for open models, though without community spaces and datasets.
Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.
