Scale AI is focused on data annotation for AI training and serves large tech companies like OpenAI, Google and Microsoft, which are developing large language models. It operates a distributed network of annotators and subcontractors via online platforms Remotasks and Outlier. The company also develops the "Scale Data Engine" platform for fine-tuning and reinforcement learning based on human feedback. Scale also has its own SEAL (Safety, Evaluations, Alignment Lab) research lab for evaluating and aligning AI models. At the exit it produces analytical reports on LLM performance, including quality metrics, safety and weaknesses. The company is 49% owned by Meta, that often raises concerns about independence, data leaks and client conflicts of interest.
