Solutions
Synthium Labs provides the expert human layer through four products. Each one is a workforce, a workflow and a quality system — expertise is the product, not the headcount. Quality arbitrage, not labour arbitrage.
Expert post-training data
SFT, preference and reasoning data written and verified by domain experts — built to your specs, held to your quality bar.
Expert model evaluation
Hard model outputs judged by experts with calibrated rubrics — preference, critique and severity-rated scores your pipeline can trust.
Expert agent evaluation
Coding and reasoning agents assessed by engineers across correctness, architecture, security and failure modes — the signals that predict production trust.
Safety & adversarial testing
Domain experts probe safety boundaries, attempt jailbreaks and surface policy violations — calibrated signal, not crowd noise.
How we scope a solution
Every engagement follows the same disciplined path: define the bar, calibrate the people, produce with QA, then scale without drift.
We scope the task, the expertise required, and the exact quality bar your deliverable must hit.
Contributors are assessed and aligned to your rubric against gold standards before production.
Work is produced, then passes through multi-stage review against the agreed quality gates.
Throughput expands as your pipeline needs it, without the quality bar moving.
