RL-gyms for AI agents

Push your agent on context-rich simulated environments and specialized RL-gyms. Get high-fidelity trajectories and graded eval signals for training and evaluating AI agents at scale.

Harness-agnostic by design: use Toloka’s harness or yours — with grading hooks and user-LLM emulation.

How it works

Managed end-to-end environment and data operations.
Built by engineers, for engineers.

Requirements
& scope

Requirements & scope

You share your goals, constraints and success criteria. We translate them in environments, trajectory schemas, rubrics, and QA plans.

Environment
design

Environment design

Containerized testbeds with seeded data and instrumented trajectory capture, invariants,
and event log.

Calibration
and seed tasks

Calibration and seed tasks

Domain experts execute seed tasks; we validate invariants, success metrics, and telemetry
to stabilize the environment. 

Data
collection

Data collection

We run demonstrations, targeted eval tasks, and long-horizon workflows to generate trajectories and graded eval signals.

Hybrid QA
(AI Agent + human)

Hybrid QA (AI Agent + human)

QA AI Agent verifies trubric adherence, logical consistency, environment invariants, task completion, and structural integrity. Senior QAs audit complex, flagged, or sampled cases.

Delivery
and integration

Delivery and integration

Receive versioned datasets, eval reports, and structured outputs ready for training and benchmarking. Always audit-ready. 

Instrumentation and reproducibility 

Instrumentation and logging 

Complete trajectory capture with state-action sequences, tool/API interactions, timing signals, environment versions/seeds,

and screen/DOM diffs.

Deterministic replay 

Versioned environments, deterministic resets, and controlled seeds enable exact repro of agent runs and human trajectories.

Structured outputs 

Per-step/per-task labels, failure categorization, safety flags, and calibrated scores

for SFT and RLAIF workflows.

Where this applies 

Web agents

Enterprise automation

Code agents

On-device and constrained agents

Safety-conscious workflows

Domain-specific agents
(Tau-style RL-gyms)

Multi‑step navigation, e‑commerce workflows, and form completion in realistic site contexts.

Aligns with public web‑interaction benchmarks (e.g., WebArena/VisualWebArena, Mind2Web, WebShop/MiniWoB++), while adding enterprise‑grade context and replayable traces.

Enterprise automation

CRM updates, document processing, approvals, and cross‑tool workflows in MCP replicas.

Covers tool‑use and planning tasks similar in spirit to multi‑tool agent benchmarks; our replicas add real permission models and auditable telemetry.

Code agents

End‑to‑end SDLC tasks in human‑simulated virtual companies with full artifact capture.

Complementary to the SWE‑bench family (incl. Lite/+), adding multi‑actor context (tickets, reviews, CI) and long‑horizon workflows.

On-device and constrained agents

Lighter RL‑gyms and Tau-Bench/Tau2‑style micro‑tasks for resource‑limited settings; supports end‑state‑only checks when needed.

Safety-conscious workflows

Controlled sandboxes for policy adherence checks and red‑teamable flows; supports human, scripted, and LLM‑judge grading.

Domain-specific agents
(Tau-style RL-gyms)

For regulated or niche verticals (finance, healthcare, legal, and more), we offer a Tau-style RL-gym process designed to produce RL-useful datasets and discriminative evals:

Domain knowledge → Environment & grading engineering → Test-case design & calibration

Privacy, security, and reproducibility

PII scrubbing, policy-compliant use of foundation models,

and client-approved data handling.

Partner with Toloka

Why Data Partnership?

Technologies

Offload environment engineering, data collection, and QA operations

to a team that does this full-time.

Faster to first useful dataset; more flexible than hiring for bursty, specialized work.

Why Toloka

Diverse and scalable supply

Depth in agentic data: instrumented, stateful environments—not just annotation.

Hybrid QA that blends tool‑enabled checks with senior human judgment, tuned to your rubric.

A rigorously vetted expert network with measurable quality controls.

Audit-ready reproducibility: versioned environments,

deterministic resets, and comprehensive logs. 

For Tau-style RL-gyms: calibrated difficulty targeting

~50% pass rate and a dedicated tri-role expert pipeline.
