Verified trajectories for frontier agents

Human intelligence, engineered into better models.

DeepLLMData builds verified training and evaluation data for frontier agents: software-engineering trajectories, enterprise computer-use workflows, and expert-designed model-stumping evaluations for AI labs and enterprises.

Capabilities

Beyond annotation. We build the work models learn from.

Hard environments, consequential decisions, and outcomes that can be checked — built with the experts who understand the work.

01Agent trajectories

Repository-level software work with executable verification

End-to-end traces across real codebases: planning, tool calls, multi-file edits, terminal execution, and tests. Built for the class of long-horizon work measured by SWE-bench and Terminal-Bench.

02Model stumping

Expose the reasoning failures hidden by general benchmarks

Domain experts design adversarial tasks, evaluation rubrics, and failure analyses for consequential workflows in finance, healthcare, research, and operations.

03Computer use

Enterprise workflows that cross tools, screens, and decisions

Long-horizon trajectories for browser and desktop agents: navigating business systems, resolving exceptions, and completing work under policy constraints.

04Professional multimodal

Video and image data evaluated beyond surface-level labels

Professionally curated visual data with scene-level semantics, spatial and temporal reasoning, physical consistency checks, and artifact evaluation.

05Post-training

Expert preference data that captures why one response is better

SFT examples, preference pairs, critiques, and rubric traces for coding, STEM, multilingual, and professional reasoning.

06Domain data

Ready-made and custom packs grounded in professional work

Finance, healthcare, law, technical, and multilingual datasets spanning reasoning, retrieval, evaluation, and multimodal tasks.

Approach

How does DeepLLMData build training-ready data?

The sequence is deliberate. Each gate turns an ambiguous capability gap into stronger, more measurable training signal.

InputA model capability that needs to improve
01

Define the target behavior

We translate your model goals into concrete task specs, difficulty bands, and acceptance rubrics — so every example has a job.

02

Match the right experts

Domain specialists — engineers, researchers, clinicians, analysts — are screened and assigned to the work that needs their judgment.

03

Calibrate and verify

Gold sets, inter-rater checks, executable tests, and iterative feedback keep the signal grounded as the program scales.

04

Deliver training-ready signal

Clean schemas, documented fields, and export formats your training pipeline can ingest without another cleanup pass.

OutputVerified data, metadata, and failure analysis
