How Cohere buys data
Runs a large in-house annotation workforce: Ashby department 'Data Quality (Contract)' with teams such as 'STEM Annotation - Engineering' and 'Code Annotation - Data Science' (Apr–Jul 2026), plus Generalist, Safety and Mandarin annotation specialists. Command A tech report (Apr 2025) says safety annotation uses 'internal annotators and specialist external vendors', multilingual annotation uses internal and external annotators, preference data uses majority vote of ≥3 annotators on a customised in-house platform, and human pairwise evals use ~65 annotators per run. Hired a 'Product Manager, Human Data' (removed Oct 2025) for 'model in the loop' annotation at scale; 'MTS, Data Analysis and Evaluation' (London, Dec 2025) designs data-collection tasks.
Modeling org (post-training, multimodal, synthetic data, evaluation, multilingual) under Chief AI Officer Joelle Pineau (since Aug 2025) and Chief Scientist Phil Blunsom; a separate Data Quality (Contract) org houses in-house annotators; Cohere Labs (research, now led by Marzieh Fadaee) publishes on multilingual/multimodal data.
