Toloka

AI agent

TendemAI 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.

Platform

Toloka ArenaPlatform

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.

Toloka TrainPlatform

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.

Writer

AI agent

WRITER AgentAI agent

An agent that plans and carries out multi-step work across a customer's own data and tools, under enterprise governance controls.

Platform

WRITER Knowledge GraphPlatform

WRITER's retrieval layer. A specialised LLM reads a customer's own documents, spreadsheets, slides and PDFs and builds a graph of the semantic relationships between them rather than storing vector embeddings, so retrieval can follow multi-hop connections, break a broad question into sub-questions and return specific source citations before WRITER's Palmyra models generate the answer.

WriterPlatform

Enterprise platform for building AI applications and agents on Writer's own models.

No counterpart

Toloka sells these in a stack layer with no product recorded for Writer yet — nothing on the other side to compare them against.

Data service

Off-the-shelf DatasetsData 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.

Toloka Physical AIData service

Human-in-the-loop data programs -- demonstrations, annotation and evaluation -- for training robotics and physical AI systems.

Toloka PlatformData service

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.

Writer sells these in a stack layer with no product recorded for Toloka yet — nothing on the other side to compare them against.

Application

WRITER Enterprise BrainApplication

Universal context layer that grounds AI agents in a company's Agent Memory (captured decisions and preferences) and Company Standards (brand, tone, compliance), listed in WRITER's own top-level product navigation alongside Models, AI Studio, WRITER Agent and WRITER for Slack.

WRITER PlaybooksApplication

Reusable, repeatable workflows in WRITER, so a piece of work done once can be run the same way again.

Agent platform

WRITER AI StudioAgent platform

WRITER's build surface: business teams assemble agents on an interoperable platform while technology teams keep visibility and governance over what ships.
