RL infrastructure vendors

These core-list vendors offer infrastructure alongside environments, data, evals or another eligible offering. Infrastructure-only providers are excluded. Hosting a customer’s dataset does not mean the infrastructure vendor supplies that data.

RL infrastructure vendors

25 vendors. 7 state they have a SOC 2 Type I or Type II report and 15 state they can run in a customer's cloud or on-prem. These are sourced statements, not independent verification. Pending and unspecified SOC 2 claims are excluded.

How to read domain and SOC 2 labels

Multi-domain means work across several task areas, not every area. Vendors appear in a specific domain filter only when that area has supporting evidence. SOC 2 entries are vendor statements, not independently verified audits: Unspecified means claimed without a stated type; Pending means in progress; Not publicly listed means we found no public statement. None of those means a completed Type I/II report. SOC 2 and deployment details remain on profiles and in comparison.
