Post-Training and RL Buildathon: The Builder Base
About this event
A one-day in-person buildathon for ML engineers, founders and researchers on post-training methods such as SFT, DPO and GRPO, reward models, RL environments and evals, organized by Devnovate with AWS.
Devnovate and AWS run a one-day buildathon in San Francisco for people who want to build with post-training techniques: supervised fine-tuning, RLHF and RLAIF, DPO and GRPO, reward models, RL environments and evals. Project ideas include fine-tuning open-weight models, training tool-using agents and designing preference datasets. A practitioner panel covers RL in production, and the day ends with demos. No prior expertise is required.
The Luma event data gives a 9:30 AM start and a 5:30 PM end, while the description text mentions a window to 7:00 PM, so confirm the finish time. The exact address is shown to registered guests only, and registration needs host approval. The AWS Builder Loft is a co-host and asks attendees to register on its own site as well.
