What comet [comet.ml] does
Comet (Comet ML, Inc.) is a New York–headquartered, privately-held software company that provides an AI developer platform for machine-learning experiment management and LLM application observability. The company serves AI/ML developers, ML research teams, and enterprise engineering organizations building and operating LLM-powered applications and coding agents. Its product surface comprises two integrated offerings: the Opik platform — covering LLM tracing and observability, automated prompt engineering via the Ollie diagnostic agent, Test Suites with 40+ LLM-as-a-judge metrics, Online Evaluation Rules, and Cost Intelligence for Claude Code and Codex — and a traditional MLOps stack including ML Experiment Management, Comet Artifacts for dataset versioning, a Model Registry, and Model Production Monitoring for data drift and custom metric alerting.
The platform is delivered through a Python SDK with TypeScript support, an MCP server for coding-agent integration, and 60+ native integrations with major AI/ML frameworks (OpenAI, Anthropic, LangChain, LlamaIndex, Hugging Face, PyTorch, TensorFlow, Keras, scikit-learn, XGBoost, Google ADK). Distribution is hybrid: a self-serve cloud product with a freemium tier (no credit card required) feeds an enterprise field-sales motion with custom Order Form pricing, Customer Hosted deployments (on-prem/VPC), and SOC 2 Type II, HIPAA, and ISO 27001 certifications. Revenue mechanics blend subscription access (priced on user count and feature tier) with usage-based billing on Span Usage and non-refundable Platform Credits for AI features that expire within 12 months.
Comet reports adoption by over 150,000 developers, 10,000+ teams, and 21,000+ GitHub stars on the open-source Opik repository. Named enterprise customers include Netflix, Uber, Stellantis, NatWest, Autodesk, AssemblyAI, Stability AI, Mobileye, Etsy, Google AI, Hugging Face, and Zencoder. The company does not disclose revenue, funding history, headcount, M&A activity, or a founding date in the available source material, and no parent company or institutional investor information is disclosed.
