Scale AI (Evaluation)
Enterprise AI data and evaluation platform powering frontier LLM development with RLHF, human preference annotation, model red-teaming, safety testing, and capability benchmarking. SEAL lab runs private evaluations for AI labs including Meta and OpenAI. Offers self-serve pay-as-you-go data labeling alongside fully managed enterprise contracts for large-scale model evaluation pipelines.
Viable option — review the tradeoffs
You need to validate that your LLM or generative AI model behaves safely and performs reliably across edge cases before production deployment, but you lack the infrastructure and expertise to run rigorous red-teaming and capability benchmarking internally.
Turnaround is 1–3 weeks for comprehensive evaluations depending on model size and test scope. Results are detailed but not real-time; this is a batch evaluation service, not continuous monitoring. Quality is high (Scale's QA improves annotation accuracy by 35% vs. industry baseline), but you're dependent on Scale's annotation queue capacity during peak demand.
You're fine-tuning a foundation model on proprietary data and need high-quality preference annotations and RLHF feedback data to align the model to your specific use case, but generating that feedback data in-house is slow and inconsistent.
Annotation quality is high and consistent (human-in-the-loop with ML validation), but cost scales with volume. Expect $0.10–$1.00 per annotation depending on complexity. Turnaround is 3–7 days for standard batches. Edge cases and nuanced preferences may require multiple annotation rounds for convergence.
Evaluation turnaround is batch-based, not real-time
Scale AI evaluations run on a managed schedule (1–3 weeks typical). If you need rapid iteration cycles or continuous monitoring of model behavior in production, you'll need supplementary tools. Scale is designed for pre-deployment validation and periodic re-evaluation, not live monitoring.
Data security and IP handling in managed evaluations
When you submit a model or dataset to Scale for evaluation, it passes through Scale's infrastructure and annotation workforce. For highly sensitive proprietary models or data, confirm Scale's data handling agreements and NDA terms upfront. Enterprise contracts include VPC deployment options and data residency guarantees; self-serve tier does not. Clarify data retention and deletion policies before submitting confidential work.
Scale AI is a managed service for evaluation and RLHF data; CAI is a methodology you implement yourself. Choose Scale if you lack red-teaming expertise or want outsourced evaluation; choose in-house if you need full control and have the team.
You want expert-run evaluations, don't have a large safety team, or need third-party validation for regulatory/stakeholder confidence.
You have deep safety expertise in-house, need complete control over evaluation methodology, or are building a proprietary safety framework.
