From SFT demonstrations to RLHF rankings and red-teaming, we supply the human signal generative models need.
Trained raters and domain experts compare responses against your rubric to produce clean preference data — with calibration to keep judgments consistent.
See LLM servicesGenerative AI training data is the human signal — ranked preferences, written demonstrations, prompts and expert judgments — that teaches a base model what a good answer looks like. Graveiens produces this generative AI training data with trained raters and STEM subject-matter experts across 25+ languages, then runs it through a four-stage QA workflow so every label is consistent and defensible. Pair it with our data annotation services and LLM fine-tuning to close the loop from raw data to a shipped model.
