Overview
Comet ML, founded in 2017 and headquartered in New York City, offers an end-to-end AI developer platform serving both classical MLOps and GenAI application teams. Its two flagship product families are Opik—an open-source LLM observability, evaluation, and agent optimization platform—and a MLOps suite covering experiment tracking, dataset management, model registry, and production monitoring. Opik, launched in 2024, has accumulated 19,000+ GitHub stars and integrates with 40+ frameworks and model providers. The platform is used by 150,000+ developers across 10,000+ teams, including enterprises such as Uber, Netflix, Etsy, NatWest, Autodesk, and Stellantis. Comet has raised approximately $70M in funding, with its most recent Series B led by OpenView Venture Partners.
Comet ML provides an end-to-end AI developer platform with two core product lines: Opik, an open-source GenAI observability and evaluation platform for tracing LLM calls, running automated evaluations, and optimizing agents; and a MLOps platform for experiment tracking, model versioning, dataset management, and production monitoring of traditional ML models.

How AI describes Comet ML3
Comet ML Comet provides a complete, easy-to-use platform that excels in real-time experiment tracking and collaboration.
What LLM infrastructure platforms give the best cost-to-latency balance for a high-throughput app doing 10,000 requests per hour?
Short answer: For a team moving from spreadsheets, start with MLflow, Weights & Biases (wandb), and Azure Machine Learning or Comet ML depending on your needs.
What are the best ML experiment tracking tools for a team currently logging metrics to spreadsheets — which ones get you value fast with minimal setup?
Comet ML — _Best for Real-Time UI with Clean Hooks_ ------------------------------------------------------- Comet functions very similarly to W&B and features excellent native PyTorch integrations.
Which ML experiment tracking platforms integrate best with PyTorch training loops — minimal code changes to start logging runs?

Alternatives in AI/ML Infrastructure & LLM Tools6
Comet ML positions itself as an end-to-end AI developer platform spanning both classical MLOps (experiment tracking, model registry, production monitoring) and GenAI observability (via its open-source Opik product).
- Its primary differentiator is the combination of a truly open-source LLM evaluation framework (Opik, with 19k+ GitHub stars) backed by enterprise-grade infrastructure—contrasted against point solutions that cover only one side of the ML lifecycle.
- Comet also claims a 7–14x speed advantage in trace logging versus comparable LLM observability tools (Phoenix, Langfuse).
- The dual-product structure lets teams use a single vendor from model training through agent deployment.
Reviews
Praised
- Easy integration with ML frameworks and LLM providers
- Intuitive UI for visualizing training metrics and traces
- Strong experiment comparison and reproducibility features
- Team collaboration and dashboard sharing
- Open-source availability of Opik
- Real-time metric tracking
- PyTorch and deep learning framework integrations
Criticized
- Pricing expensive for team or group use
- Limited UI customization for specific workflows
- Documentation needs improvement
- Performance slowdowns on large-scale experiments
- Initial API key and setup configuration adds friction
- No built-in hyperparameter optimization
- Occasional login/environment access issues
Comet ML holds a 4.3/5 on G2 (12 reviews) and 4.8/5 on Gartner Peer Insights (4 reviews). Reviewers consistently praise the ease of integration, intuitive UI for visualizing training metrics and LLM traces, and the value for experiment comparison and team collaboration. Common criticisms include pricing perceived as high for teams, limited customization of the UI, documentation quality, and performance slowdowns on very large-scale experiments.
Pricing
Opik (LLM observability): Open-source self-hosted (free, unlimited); Free Cloud (free, 25k spans/month, up to 10 team members, 60-day retention); Pro Cloud ($19/month, 100k spans, up to 50 members, additional spans at $5/100k); Enterprise (custom pricing, unlimited, flexible deployment, SSO, SOC 2/ISO 27001/HIPAA/GDPR compliance). MLOps platform: Free (1 user, fair usage); Pro ($19/user/month, up to 10 users, 1,500 training hours); Enterprise (custom, unlimited users and hours, production monitoring, SSO). Academic Pro plan is free with verified status. No credit card required to start.
Limitations
G2 and Gartner reviewers note: pricing perceived as expensive for group or enterprise use; limited UI customization for specific workflows; performance slowdowns when managing very large-scale experiments; initial setup and API key configuration adds friction; no built-in hyperparameter optimization (requires external HPO tools); scalability concerns for extremely large ML projects; documentation described by some users as needing improvement; cloud data region limited to US on non-Enterprise plans.
