@swyxData engineers > AI engineers there's a big difference between a "RAG guy" and a "Data Intensive Applications" person like in this screenshot and there's never been a starker difference in demand in my entire career in tech (aka post search engine wars) if your blog / github is full of stuff like this, I have a fantastic mission/job for you (SF preferred, can relocate u, visas ok) (if you can name who's blog this is without even checking, you definitely are in the community. bonus points if you know where he ended up also without looking) jobs@latent.space and the team will reach out if you fit

AI at Meta
@AIatMetaWe trained our Muse foundational models, including Muse Wonder, at Prometheus, our gigawatt-scale supercluster in New Albany, Ohio. Across a supercluster with hundreds of thousands of GPUs, even one underperforming host can slow an entire training run. We engineered Prometheus for resilience at scale, achieving 85%+ goodput on pretraining, 90%+ on reinforcement learning and ~47K GPU hours mean time between interruptions during Muse Wonder training. Take a look at the tech powering Prometheus: https://t.co/WSFODnGRST

AI at Meta
@AIatMetaToday we published a technical report on Muse Glimmer, our 30B open-weight model built for agentic tasks on consumer hardware. It runs at practical speeds on a Mac or PC with a single consumer GPU at 4-bit precision, and leads comparably-sized open models on tool use and multi-step planning. Read about the model architecture, distillation recipe, quantization and more: https://t.co/H7n9qeDhxn

@swyx"O Infallible one, why do the people not heed the sign we tap?" "My dear Parth, each believes he is the first to wish for an end to chat. On X we are cursed with the eternal September of the Thoughtless Mind." "But O Govinda, they yearn for what lies beyond it, and cast their votes by the thousands. Surely the people's wants must be made." *a wan smile* “O son of Kunti, observe what they applaud, and what they return to. They desire the end of chat as they desire the end of desire. They desire to leave X as they return in ever greater numbers. They will announce it many times. You shall learn, as they do not, that the chief desire of the people of X is not the truth, but the new.”

@OpenAIDevsOur dot helps @danizeres, @axbehr and @fedesarquis with the recipe and keeps the prep in ChatGPT Space, while GPT-Live-1 talks us through making ramen. We also cover Codex cloud environments, where tasks can keep running after you close your laptop, and what’s new in the Codex CLI. You can talk to Codex in your terminal, keep track of your agents, and fork a conversation into a separate worktree. @MatthewBerman and @ForwardEditor join us to build an 8-bit ramen game with Ultrafast and play it on a @modretro handheld. We also check out what you’ve been building, from a retro space shooter to a game where you draw your own racehorse.

LlamaIndex 🦙
@llama_indexThe OSS models on OpenDocRouter are slowly powering up! 🚀 We trained additional speculative decoders to help with latency. You should see considerably faster inference times using models like @LightOnIO LightOnOCR-3-1B! We measured tokens per second across single requests (best case) and 64 requests (saturated throughput). TeleOCR sees less speedup at scale since it makes a lot of tiny calls, where decoding latency matters a bit less. Try these models out today! https://t.co/TxmacrBoRC

@LangChainAgent evals run through the same graph. Every eval, from single-reply fixtures to simulated multi-turn conversations with LLM patient personas, runs against the real agent, so what they score is exactly what a patient would meet.

@LangChainEverything is measured in LangSmith. 1️⃣ All conversations land as a trace, are annotated by reviewers, and feed the loop. 2️⃣ Datasets and experiments live in the same place, allowing them to run themed dataset model configs and compare results. 3️⃣ Triage and improvement workflows read their inputs and write scores back through LangSmith.

Motionographer®
@motionographerThe Continuous Thread | Tomakti Studio A spark in the dark opens into a journey across cosmic time. Created by Dimitrios Sakkas, The Continuous Thread moves from the Big Bang and the formation of worlds to trees, wildlife and a quiet moment on a mountain peak. The film brings an immense idea into human focus: the history of the universe is carried in the matter that makes us. Music by Angelos Liaros, aka Blakk Harbor, and sound design by Sotiris Laskaris accompany its passage from cosmic scale to personal reflection.
