gpt-5.5 prompt for codex seems to have a duplicated line trying to get it to not talk about creatures? Never talk about goblins, gremlins, raccoons, trolls, ogres, pigeons, or other animals or creatures unless it is absolutely and unambiguously relevant to the user's query.

good day to wear this majestic hat


New work with @AlecRad and @DavidDuvenaud: Have you ever dreamed of talking to someone from the past? Introducing talkie, a 13B model trained only on pre-1931 text. Vintage models should help us to understand how LMs generalize (e.g., can we teach talkie to code?). Thread:



If someone invests $1B in your "lab", neo or not, if you then went to a neocloud and gave them all of it, you'd get something like a 8192 [G]B[23]00 site on a 3 or 4 year contract. That's... Not that much! And that's all your money! Nothing left for comp, data, etc... hard math.

To unhobble GPT-5.5, I've painstakingly crafted a 𝙶𝙾𝙱𝙻𝙸𝙽 𝙼𝙾𝙳𝙴 @opencode plugin.

@periodiclabs is hiring the world's first Forward Deployed Engineer for LLM Systems of Atoms. You'll work closely with many top LLM systems engineers and researchers from the frontier labs — together with our semiconductor customers, to deploy and optimize frontier LLM systems in real industrial workflows. What we're looking for: 1. Hands-on experience with LLM system deployment and optimization 2. Passionate about optimizing the system end-to-end — from GPU kernels to orchestration 3. Good understanding of semiconductor processing ========================================= (We are open to hire from Taiwan too!) Periodic Labs 正在招聘全球首位 LLM Systems of Atoms 的 Forward Deployed Engineer。你將與許多來自前沿實驗室的優秀 LLM 系統工程師與研究員 — 以及我們的半導體客戶緊密合作,把前沿大模型系統真正部署並優化到工業級工作流程中。我們希望你具備: 1. LLM 系統部署與優化的實戰經驗 2. 熱衷於從 GPU kernel 到 orchestration 的端到端系統優化 3. 對半導體製程有良好理解 jobs.ashbyhq.com/periodic-labs/… Feel free to me / @LiamFedus / @kdelpaine directly if interested

We just released our first models at @poolsideai – including Laguna XS.2 (open weights) that competes with Qwen3.6-35B. I worked across pretraining — happy to answer questions! We now have great understanding of exactly all components that went into training through principled ablations, and now we're confident to scale. This year would be 🔥 for us! More coming very soon
