The release retires the monitors feature flag and raises the org limit to 20 while pushing multiple v4 data-pipeline reads to the events table, advancing Langfuse's v4 architecture migration for both cloud and self-hosted users.
Teams building agentic systems can now iterate between SFT and RL on managed CoreWeave infrastructure without manually shuttling model artifacts, cutting the operational overhead that typically delays getting fine-tuned agents into production.
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.
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.
