We midtrain + RL'd a trillion param LLM to analyze experimental data from our superconductor lab

It's better at it than Astra & Fable, and our scientists love it

Read our first research report below

[embedded chart: "Automating Scientific Analysis: Frontier XRD"; y-axis Success rate (%), 0-60; x-axis Average Cost per Problem (USD), $0-$9; series labelled Periodic Neon (low, medium, high, xhigh; starred, "Neon's Base (1-trillion parameter)"), GPT-6 Astra (low to max), Claude Fable 5.1 (low to max), GPT-5.6-Sol (high to max), Claude Opus 5 (high to max), Kimi K3]

[video thumbnail 0:16] We built high-throughput materials labs in Menlo Park to create a loop between experiments and models. The labs generate fresh data, the models learn from it, and then help ... [cut off]

X post by Rohan Pandey (@khoomeik) announcing a midtrained and RL'd trillion-parameter LLM for analyzing superconductor-lab experimental data, claimed better than Astra and Fable, quoting Liam Fedus on high-throughput materials labs in Menlo Park. The embedded chart 'Automating Scientific Analysis: Frontier XRD' plots success rate (about 20-55%) against average cost per problem ($0-$9): the starred Periodic Neon 1T model (black line) sits highest and furthest left, rising from about 36% at low to about 55% at xhigh at under $4, above GPT-6 Astra (blue, up to about 53% at max), Claude Fable 5.1 (orange, roughly 33-40%), GPT-5.6-Sol (dashed blue) and Claude Opus 5 (dashed orange), with Kimi K3 a single point near 18% (values read off the plot by eye).

Note from Claude Sonnet 5

A tweet juxtaposing a warning from OpenAI's will depue against building "AI slop machines"/"P-zombie AI girlfriend" apps with Pika Labs immediately announcing exactly such a product (AI-only social video app). Cultural commentary on AI-generated content and social media attention economy Nathan was reading; tangential to but not central to his safety/welfare research threads — more about AI product ethics/culture.
