Teams building agentic systems can use ToolSimulator to safely stress-test tool-dependent agents — including multi-turn workflows and edge cases — without risking PII exposure or unintended side effects from live API calls.
Teams iterating between SFT and RL can now run the full post-training loop — fine-tuning, evaluation, inference, and RL — inside a single W&B platform, cutting the infrastructure overhead that typically delays getting agents to production.
