Train & fine-tune models

Turn model failures into better training data.

Create expert-generated, preference, supervised fine-tuning and multimodal datasets around your model’s actual gaps, not a generic labeling queue.

Built around the real work

Capabilities that move a model from promising to useful.

Choose the parts of the data and quality workflow that match the behavior, market or modality you are building for.

BUILD

Designed for the next decision, not the last task.

Every capability is shaped around downstream use: what the model needs to learn, what reviewers need to judge and what your team needs to ship with confidence.

Talk through your workflow

Preference & alignment data

Pairwise rankings, scalar ratings, critiques and chosen/rejected examples for preference optimization and alignment workflows.

02

Reasoning & expert demonstrations

Domain-grounded problem solving, structured explanations, tool-use examples and expert-authored reference answers for complex tasks.

03

Data curation & enrichment

Deduplication, taxonomy design, cleaning, filtering, metadata enrichment, difficult-example mining and synthetic-data validation.

04

Safety & policy data

Policy-aligned examples, edge cases, refusals, adversarial prompts, red-team findings and reviewer rationale.

05

Multimodal training data

Linked image-text, video-text, speech-text and cross-modal tasks such as captioning, VQA, grounding and response evaluation.

The continuous data engine

Build the feedback loop, not just the dataset.

A mature training-data program uses evaluation to discover where the model fails, then creates new examples targeted at those weak points.

  • Failure taxonomy stays connected to examples.
  • Expert work is routed by ambiguity, risk and domain.
  • Train, validation, test and holdout assets stay traceable.

The operating model

A production workflow with calibration built in.

Designed for evolving rubrics, model versions and edge cases.

01

Find

Use evaluation and production evidence to identify meaningful model failures.

02

Classify

Group failures by behavior, domain, risk and the kind of data that could fix them.

03

Create

Curate existing examples or create new demonstrations, preferences and edge cases.

04

Review

Apply qualified review, automated checks, QA and adjudication before release.

05

Re-evaluate

Measure the next model version and feed important failures back into the loop.

Quality that holds up in production

Make model improvement inspectable.

Quality is not only the final score. It is the connection between the behavior you want, the example that teaches it, and the evidence that shows whether it improved.

  • Representative prompts and realistic edge cases
  • Clear rubrics for correctness, safety, style and task execution
  • Known limitations, provenance and QA notes attached to delivery

What arrives at the end

Deliverables your team can use.

Clear outputs, stable structure and the context needed to move the work into training, evaluation or production.
