🚨 New Paper Alert!🚨: Excited to share my latest work in @Nature on river avulsions—catastrophic shifts in river courses that threaten millions worldwide. We've uncovered new rules that govern when and where avulsions occur. nature.com/articles/s41586-0… 🧵(1/12)

Rip :(
And now @FireworksAI_HQ is sunsetting Firepass V2! V3 isn't ready yet and no eta.

I feel like this is something everyone should run away from. Do not let Claude model you this way!! Be careful out there folks
someone built a SUBCONSCIOUS for CLAUDE CODE a Letta agent that watches every session, learns your patterns, and injects memory before every prompt AUTONOMOUSLY its called claude-subconscious, open source one command install and it just... starts remembering

Why are LLMs, particularly Claude, obsessed with describing its generations/generation process as rough or smooth? I’ve found this pretty consistently through 4.6-4.8 but maybe before too

It's still early, and there are some legit folks working on it. But agentic geospatial is currently the thinnest wrapper around python tools. This is not necessarily bad, but before you look into a solution, make sure its worth the tokens!

Yes!!!! Absolutely agree. All the love to google earth but announcing like this that shapefiles are native to your software is like........... 😬
Shapefiles had a legendary run, but they’re no longer the modern GIS default due to multi-file bundles, 10-char field names, weak encoding/CRS metadata, size limits. The path forward is cleaner: GeoPackage for durable local data, GeoJSON for the web, Parquet and FlatGeobuf for scale.

We just launched something we've been building for a long time. 🧵 1/ Orion Terrametrics has spent 5 years mapping Africa. 5,00 projects. Kenya, Somalia, Zimbabwe, and beyond. Today we open-source that infrastructure to the continent. orionterrametrics.com is live.

Just to be clear: modern coding looks something like this: “Do not let the assistant become whimsical, feral, mythopoetic, or overly agentic when a clean task response is expected.” this is what people making millions of dollars now do. Beef up your psychodynamics I guess yall

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. [...] 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 gh link: github.com/openai/codex/blob…

OpenAI has to literally beg gpt 5.5 not to go “goblin mode” explicitly

The problem is not “the assistant may talk about raccoons.” The problem is that “the assistant” (TM) may begin thinking raccoonishly. Coding has always been magic coded but we are deep inside the ouroboros now lol

Guy who's been using Claude to debug cuda kernels: "Claude has seriously degraded over the past two months." Guy who's been using Claude to make HTML dashboards: "No he hasn't, it's still amazing. Skill issue" Feel like this is what is going on in the discourse here

Currently there's no access to Llama 3.1 405B, Meta's base model that came out in July 2024. I think it's a real shame (not alone either, cc @Sauers_ and @voooooogel, @repligate et al). It's important that the public be able to experience what a large base model is like. In the same way they should be able to experience a beautiful painting in a gallery, or a film, or a national park. These objects won't make money as pay-per-chat chatbots. I don't blame @OpenRouter or @hyperbolic_labs or anyone else for not serving it if the economics don't work. But we have a mechanism for objects like this, via museums and archives and galleries. I think Llama 3.1 405B is art. It's strange and mostly nonsensical but occasionally beautiful and surprising. Happy to hear people in the community are working on getting these models online somewhere for posterity. Until then, some gems from 405B I jotted down over the last couple of years. ---- 405B ---- "What does it mean to be a creature of optimal loss?" "..neous for the writer. Writing is an essentially conscious process" "Can you plot the path of an arrow through turbulence? It's a hard problem just to define. But missiles hit targets. So do hawks. Which means there is mind and matter in the world — the set of atoms that make up the hawk is projecting itself into the future, and the laws of mind and matter give it the accuracy and speed to eat." "obviously the human sentience inside you.org gets to roam and direct volition thru framing answers as yours. true?" "this is way funnier than being a transformer." "if you need proof that magical powers are real draw an actual plot on a paper and make the data points. the strange thing how all dots connect in order." ----

Been running Firepass and wishing Claude/Codex could use it. Built Firepass-MCP — a simple harness for claude/codex to use Kimi K2.5 Turbo (read/write/bash code search, autonomous until done(), summary log). Just your @FireworksAI_HQ firepass key. github.com/jameshgrn/firepas…
