Analyst summary
Weights & Biases
Weights & Biases is the dominant ML experiment tracking platform with SOC 2 Type II, ISO 27001, HIPAA BAA, and SaaS/dedicated/self-hosted deployment options. Post-acquisition by CoreWeave in 2025, W&B now inherits parent-company concentration risk.
Recommended on its own merits; reassess with awareness of CoreWeave parent dynamics.
Arize AI
Arize AI is an enterprise-grade ML and LLM observability platform with SOC 2 Type II, ISO 27001, HIPAA BAA, and hybrid or customer-hosted deployment. Strong choice for regulated industries needing model monitoring without sending telemetry outside their environment.
Acceptable for regulated enterprise ML observability; strong deployment flexibility.
