W&B Launches ARIA: Auto-Analyzing Experiments to Launch Next Training Run
wandb · x · 2026-08-13
Weights & Biases (W&B) announced that its platform has been used to improve models a billion times. To shorten the AI development loop, W&B partnered with CoreWeave to introduce ARIA. The agent automatically reads experiment data, forms hypotheses, launches the next run, and scores it against baselines. The underlying compute is handled by Serverless Inference, Serverless RL, and Serverless SFT, freeing developers from infrastructure concerns.
