RLHF in 2026: why quality concentration beats scale
High-profile breaches showed that black-box, low-context evaluation cannot scale safely. The alternative is concentrated, transparent expertise.
The wake-up call
The high-profile data breaches that hit AI evaluation platforms in 2026 were not outliers - they were predictable. When you build an AI evaluation platform on a US-housed, opaque, sub-contracted crowd, the failure modes compound.
The alternative
Quality concentration. Fewer evaluators, deeper expertise, full transparency on credentials and inter-rater agreement. EU/UK clients in particular cannot use platforms that hide who reviewed their AI.
What good looks like in 2026
- Verified credentials, disclosed per project
- Inter-rater agreement reported per project
- Error taxonomies tied to the AI's deployment risks
- A DPA on day one
