Synthetic data

Datasets engineered to a specification, not sampled and hoped for.

You tell us what your model must do. We define the schema, distribution and acceptance criteria first, generate to that spec, and return data verified against it.

What we generate

Instruction and chat data

Single-turn and multi-turn examples for supervised fine-tuning, with controlled difficulty, tone and format.

Grounded Q&A for RAG

Questions and reference answers generated from your documents, each linked to the passage that supports it.

Agent trajectories

Tool-calling traces and multi-step workflows, including failure and recovery paths, validated against your tool schemas.

Extraction and classification

Structured-output and labeling data with a fixed label schema and measured label accuracy.

Indic and code-mixed text

Hindi and Hinglish data with native-speaker review. Other languages are scoped per project once reviewer coverage is confirmed.

Edge cases and adversarial inputs

Rare, ambiguous and hostile inputs that real traffic produces too seldom to train or test on.

Methods

Established techniques, applied with controls.

Seed-based expansion

Grow a small set of real or expert-written examples into a larger one, the approach popularized by Self-Instruct, with similarity filtering to drop near-copies.

Persona and scenario matrices

Systematically combine user types, intents, constraints and difficulty levels so coverage is designed rather than left to chance.

Grounded generation

Generate from source documents and keep the link to the supporting passage, so factual claims can be verified.

Rejection sampling

Over-generate, score against a rubric and keep only what passes, rather than shipping everything the generator produced.

Acceptance criteria

What "done" means is agreed before we start.

Thresholds depend on your task and risk tolerance, so we set them with you during scoping and report against them at delivery. A dataset that misses them is revised, not shipped.

Schema validity. Every record parses and matches the agreed schema.
Duplication. Exact and near-duplicate rates stay under the agreed limit, within the set and against your existing data.
Label accuracy. Measured on a human-audited sample and held to the agreed target.
Coverage. Each scenario, difficulty tier and rare category you care about is represented.
Real-data fit. Distribution and downstream performance compared against human-labeled data where it exists.

Describe the task. We will tell you what the data should look like.
