What you likely need
You're a deep technical researcher at OpenAI with real publication credibility but limited public builder presence, so the events most valuable to you are those that accelerate your visibility in the ML open-source and research communities. You'd benefit most from small, high-signal gatherings where you can swap notes with other researchers turning papers into public artifacts, and where your NeurIPS work gets in front of the people who cite, star, and share. Think less networking-for-networking's-sake and more rooms where your technical depth is the entry ticket.

- positioningA NeurIPS '25 authors dinner for researchers actively promoting accepted papers on Hugging Face and Papers With Code to swap distribution tactics and cross-promote each other's work
- positioningAn OpenAI and DeepMind researcher roundtable for ML engineers shipping open-source repos alongside their day jobs, focused on crossing the 10-public-repo builder credibility threshold
- tacticalA Hugging Face model-release happy hour for researchers uploading weights and datasets from published papers to compare strategies for maximizing download metrics and community adoption
- positioningA Show HN alumni meetup for ML researchers who have launched or are planning their first 'Show HN' post, workshopping how to frame research projects for Hacker News karma and technical community recognition
- positioningA reinforcement-learning and alignment research dinner for authors working on RLHF, RLAIF, and reward-model papers adjacent to PeRL, to build the citation network and co-promotion relationships that push h-indexes past 50
- tacticalA researcher identity and scholarly profile office hours for ML engineers dealing with OpenAlex or Semantic Scholar attribution errors — like chemistry-field misattributions — to clean up publication records before job searches or grant applications
- positioningA GitHub open-source growth roundtable for ML researchers between 200–800 followers strategizing on repo launches, README quality, and community contribution patterns to break the 1,000-follower recognition threshold
- positioningA researcher-to-builder transition dinner for OpenAI, Anthropic, and Google DeepMind technical staff exploring how to build a public builder identity without leaving their research roles, sharing what open-source side projects have compounded fastest
