Highly filtered and consequential AI developments.
The ladder of intelligence is the ladder of abstraction. L1: Memorizing answers (no generalization) L2: Interpolative retrieval of answers, pattern matching, memorizing answer-generating rules (local generalization) L3: Synthesizing causal rules on the fly (strong…
The universe is a beautifully consistent system of rules. Intelligence is the efficiency with which you can go from the output of these rules (what you can observe) back to the rules themselves.
Super excited to announce SIMA 2! It’s a general agent that can understand & reason about complex instructions and complete tasks in simulated game worlds, even ones it has never seen before. Incredible to see how it can learn just from self-play… a crucial step towards AGI
The reason it is so important for everyone to keep pretending that AGI is definitely right around the corner is that there is now over $1T of investment riding on this belief (either already expended, or committed) Current (and recent past) capex cannot be justified by current…
Technically, reasoning isn't needed. The model, when reasoning, doesn't have access to any additional information, so all it needs to answer your question or solve your task is already there in the weights. Reasoning is a duct tape patch that we use because it provides a better…
Alibaba’s updated Qwen3 Max is the most intelligent non-reasoning model, placing ahead of Kimi K2 0905! Key takeaways: ➤ Intelligence uplift: Intelligence increased by +6 points to 55 in our Artificial Analysis Intelligence Index. Qwen3 Max is currently the most intelligent…
Today, multiple users discovered a shocking fact: After explicitly selecting GPT-4o in the ChatGPT interface, the system actually returns responses from GPT-5. By clicking the "regenerate" button, users can clearly see which model is actually being called in the backend. This is…
Introducing two new Gemini 2.5 models (Flash and Flash-Lite) which are more intelligent, cost effective, and token efficient. You can keep up with our latest models through `gemini-flash-latest` and `gemini-flash-lite-latest`!!
"AI isn't replacing radiologists" good article Expectation: rapid progress in image recognition AI will delete radiology jobs (e.g. as famously predicted by Geoff Hinton now almost a decade ago). Reality: radiology is doing great and is growing. There are a lot of imo naive…
In 2016 Geoffrey Hinton said “we should stop training radiologists now" since AI would soon be better at their jobs. He was right: models have outperformed radiologists on benchmarks for ~a decade. Yet radiology jobs are at record highs, with an average salary of $520k. Why?
In 2023 there was a big uptick in companies marketing their products as “AI powered”. 2026 will be the year of companies marketing their products as “AI free” (a trend already underway)
based on the full video, it looks like it's just running through a sequence of fighting actions as he's disrupting it
New SOTA on ARC-AGI - V1: 79.6%, $8.42/task - V2: 29.4%, $30.40/task Custom submissions by @jerber888 and @_eric_pang_ are now the best known solutions to ARC-AGI Both: * Are open source * Use Grok 4 * Implement program-synthesis outer loops with test-time adaptation
OpenAI just published their official prompting guide for GPT-5. Master these 6 critical prompting techniques:
Gemini 2.5 Flash Image (Nano Banana) best practices 🍌🍌🍌 - Be hyper-specific: The more detail you provide, the more control you have. Instead of "fantasy armor," describe it "ornate elven plate armor, etched with silver leaf patterns, with a high collar and pauldrons shaped…
Continuing the journey of optimal LLM-assisted coding experience. In particular, I find that instead of narrowing in on a perfect one thing my usage is increasingly diversifying across a few workflows that I "stitch up" the pros/cons of: Personally the bread & butter (~75%?) of…
Grok 4 is still state-of-the-art on ARC-AGI-2 among frontier models. 15.9% for Grok 4 vs 9.9% for GPT-5.
the openai IMO news hit me pretty heavy this weekend i'm still in the acute phase of the impact, i think i consider myself a professional mathematician (a characterization some actual professional mathematicians might take issue with, but my party my rules) and i don't think i…
1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).
Introducing the world's best (and open) speech recognition models!
Grok 4 got just released with SOTA results in ARC-AGI-2, Humanity Last Exam and select other benchmarks (but not coding). It's $30 on grok.com. It's available in Cursor. There is API.
