Comet ML
Platform
Comet's production-monitoring product for tracking deployed-model performance and data drift across the ML lifecycle.
GenAI observability and agent-testing platform from Comet, for tracing, evaluating and debugging LLM applications.
Toloka
Platform
An independent evaluation platform that ranks frontier LLMs on agentic tool-use tasks using private, non-contaminated benchmarks across industry domains, scored on a pass^5 reliability metric, with the underlying RL Gyms and evaluation datasets available to license.
A self-serve service that lowers per-request inference cost through two tools - fine-tuning LoRA adapters on frozen Qwen3 base models to replace a frontier API on a narrow task, and prompt gisting that compresses long instruction prefixes into learned tokens.
No counterpart
Comet ML sells these in a stack layer with no product recorded for Toloka yet — nothing on the other side to compare them against.
Application
Opik feature that tracks and attributes AI/coding-agent token spend (Claude Code, Codex) across engineering teams, surfacing recoverable-spend opportunities.
Developer tool
Opik feature (also available as an open-source SDK) that automatically iterates and tunes system prompts across seven optimization algorithms before freezing them for production.
Comet's dataset- and model-versioning product for tracking artifacts and lineage from training through production.
Comet's experiment-tracking product for logging, comparing, visualizing and reproducing machine-learning training runs.
Toloka sells these in a stack layer with no product recorded for Comet ML yet — nothing on the other side to compare them against.
AI agent
A hybrid AI-plus-human agent that takes a delegated task - research, data analysis, copywriting, design or development - has AI do the first pass, then routes it to one of 10,000+ vetted experts for verification and multi-layer QA, returning results in 2-24 hours.
Data service
Toloka's catalogue of ready-made training datasets sold outright — three named at the time of writing (Tau-bench Dataset Extension, University-level Math Reasoning, Multimodal Conversations) — as distinct from the custom data work its Platform sells.
Human-in-the-loop data programs -- demonstrations, annotation and evaluation -- for training robotics and physical AI systems.
A self-serve platform where an AI agent turns a described data goal into a full human-annotation pipeline - RLHF and preference data, data collection, instruction tuning, model evaluation, synthetic-data validation and content-moderation QA - with LLM-based quality checks on the output.
