Weights & Biases celebrated crossing 1 billion logged runs by overhauling Weave for agent session observability and launching CoreWeave ARIA, an engine that autonomously formulates hypotheses and executes RL fine-tuning runs.
Key Takeaways
- ✓Introduces an MCP server for coding agents to inspect metrics, pinned baselines, and diffs programmatically;
- ✓Weave evolves into a production agent observability suite with governed registries for prompts and datasets;
- ✓ARIA engine automates hypothesis generation and serverless RL/SFT execution without manual cluster management.
