Show HN: HiddenState – How I keep up with 500+ ML papers a day

https://hiddenstate.io/archive/2026-02-18

HiddenState monitors arxiv, Reddit, GitHub, HN, Bluesky, HuggingFace, OpenReview, PapersWithCode, and a handful of research blogs. Every few hours it pulls new items, throws most of them away (+95%), and clusters what survives by the specific technical constraint being attacked. Not by topic, not by domain.

Example from this week; 7 independent VLA papers dropped within 24 hours from 9 different orgs. Xiaomi, GigaBrain, RISE, all attacking sim-to-real transfer for robotic manipulation. None coordinating. That kind of convergence is hard to spot unless you're reading everything.

Each mechanism gets a 0-100 score across convergence, implementation evidence, engagement, and significance. Orgs are deduplicated so a single lab posting on five platforms doesn't inflate the signal.

Python, SQLite, Claude for clustering, Cloudflare Pages. Free, no tracking. Looking for any and all feedback and thoughts! Cheers!

From today's report: three separate papers on stabilizing RL fine-tuning for LLM reasoning landed from three different groups. STAPO silences rare token probability spikes during training, Experiential RL adds memory of past feedback to handle sparse rewards, and TAROT uses test-driven curriculum RL for code generation. Read individually they're three unrelated papers. Clustered together they tell you the field is stuck on the same problem.

Separately, a paper on "Learning to Configure Agentic AI Systems" and a Reddit post analyzing 44 agent frameworks both surfaced within hours, both independently identifying context management as the key bottleneck. Neither referenced the other.

That's what the site is built to find. Curious if these match what people here are seeing in their own work/pubs/research.
