You can now download and tweak Grok 2.5 for yourself as it goes open source

Unhinged as Grok may be, it's now open source. xAI's CEO, Elon Musk, posted on X that the company made the older Grok 2.5 model available to the public and will do the same with the upcoming Grok 3. For now, anyone can download, run and even tweak Grok, whose source code was uploaded to the Hugging Face platform. However, there are restrictions to xAI's open-source license, which doesn't let people use Grok to train, create or improve other AI models. It's not the first time xAI has made its mo

SQLite (with WAL) doesn't do `fsync` on each commit under default settings

SQLite (with WAL) doesn't do `fsync` on each commit under default settings SQLite has a WAL mode (the default is journal mode), but you’re likely using it if you want higher write throughput. SQLite also has a PRAGMA called synchronous which configures how fsync is called. The default is NORMAL . This is what the docs say: [..] but WAL mode does lose durability. A transaction committed in WAL mode with synchronous=NORMAL might roll back following a power loss or system crash. In WAL mode when

The Hidden Ingredients Behind AI’s Creativity

The original version of this story appeared in Quanta Magazine. We were once promised self-driving cars and robot maids. Instead, we’ve seen the rise of artificial intelligence systems that can beat us in chess, analyze huge reams of text, and compose sonnets. This has been one of the great surprises of the modern era: physical tasks that are easy for humans turn out to be very difficult for robots, while algorithms are increasingly able to mimic our intellect. Another surprise that has long p

ThinkMesh: A Python lib for parallel thinking in LLMs

ThinkMesh ThinkMesh is a python library for running diverse reasoning paths in parallel, scoring them with internal confidence signals, reallocates compute to promising branches, and fuses outcomes with verifiers and reducers. It works with offline Hugging Face Transformers and vLLM/TGI, and with hosted APIs. Note: This is still in it's early development phase and breaking changes can sometimes occur Highlights Parallel reasoning with DeepConf‑style confidence gating and budget reallocation

AGI is an engineering problem, not a model training problem

Published: Aug 13, 2025 | at 11:00 AM We’ve reached an inflection point in AI development. The scaling laws that once promised ever-more-capable models are showing diminishing returns. GPT-5, Claude, and Gemini represent remarkable achievements, but they’re hitting asymptotes that brute-force scaling can’t solve. The path to artificial general intelligence isn’t through training ever-larger language models—it’s through building engineered systems that combine models, memory, context, and determ

Evaluating LLMs for my personal use case

Most models are excellent, so cost and latency dominate. It’s great that AI can win maths Olympiads, but that’s not what I’m doing. I mostly ask basic Rust, Python, Linux and life questions. So I did my own evaluation. I gathered 130 real prompts from my bash history (I use command line tool llm). I had Qwen3 235B Thinking and Gemini 2.5 Pro group them into categories. They both chose very similar ones, broadly (with examples): Programming - “Write a bash script to ..” Sysadmin - “With curl

ChatGPT-5 Impressions: Fast, but a Bit Impersonal

ChatGPT-5 likes getting straight to the point. For some, that's a reprieve from its chattier predecessor, GPT-4o. For others, something will certainly seem off. Despite the hype leading up to OpenAI's launch of GPT-5, it ultimately doesn't feel too different from 4o. The quality of responses in my ongoing testing seems to be at the level of past models, including the o3 "reasoning" model. The major difference is that some responses generate very quickly in relatively few words, while others ca

Apple trained a large language model to efficiently understand long-form video

Apple researchers have developed an adapted version of the SlowFast-LLaVA model that beats larger models at long-form video analysis and understanding. Here’s what that means. The nerdy bits Very basically, when an LLM is trained to also understand video, it learns to split videos into frames, apply computer vision to extract visual features, analyze how those features change over time, and align all of that with language so it can describe or reason about the video in the form of text. One v

College student’s “time travel” AI experiment accidentally outputs real 1834 history

A hobbyist developer building AI language models that speak Victorian-era English "just for fun" got an unexpected history lesson this week when his latest creation mentioned real protests from 1834 London—events the developer didn't know had actually happened until he Googled them. "I was interested to see if a protest had actually occurred in 1834 London and it really did happen," wrote Reddit user Hayk Grigorian, who is a computer science student at Muhlenberg College in Pennsylvania.

GPT-5 usage limitations: what are they, how does this compare to GPT-4 family?

Edgar Cervantes / Android Authority GPT-5 arrived a few weeks ago, though its rollout hasn’t been entirely smooth. While the model shows plenty of promise, its debut also meant the abrupt removal of every other GPT model from ChatGPT’s user-facing UI. Since then, some old models have returned, and there have been a few other changes to the way the system works. Furthermore, many of the initial GPT-5 usage limits have been temporarily enhanced since launch. Let’s dive in and take a closer look

Building AI products in the probabilistic era

I was recently trying to convince a friend of mine that ChatGPT hasn't memorized every possible medical record, and that when she was passing her blood work results the model was doing pattern matching in ways that even OpenAI couldn't really foresee. She couldn't believe me, and I totally understand why. It's hard to accept that we invented a technology that we don't fully comprehend, and that exhibits behaviors that we didn't explicitly expect.

I Gave GPT-5 Some Work Tasks in Copilot. Here's What's New

OpenAI's latest GPT-5 model promises to be the most advanced AI assistant yet, but for the millions of workers using Microsoft Copilot for their daily routines, the reality is a bit more nuanced. Microsoft announced last week that GPT-5, OpenAI's latest ChatGPT AI model, is now integrated across its Copilot services, including Microsoft 365 Copilot, Copilot Studio, GitHub Copilot and the standalone Copilot app. While GPT-5 does deliver some noticeable improvements in polish, detail and helpfuln

Meet Surya, a New AI Model From NASA and IBM That Can Predict Solar Flares

Today's solar flare forecasting is pretty straightforward. Earth has several instruments pointed at the sun that monitor it, and when a solar flare erupts, NOAA predicts whether it'll hit Earth and reports it via the Space Weather Prediction Center. But NASA and IBM may be able to do this faster and with a little more accuracy thanks to a new artificial intelligence model named Surya. Surya, which is Sanskrit for "Sun," is a 366M-parameter AI model developed to analyze the various cool things t

Honor's Magic V5 Boasts On-Device Live AI Call Translation for Guaranteed Privacy

"Hola! ¿Hablas inglés?" I asked the woman who answered the phone in the Barcelona restaurant. I was calling in a futile attempt to make a reservation for the CNET team dinner during Mobile World Congress this year. Unfortunately, I don't know Spanish (I learned French and German at school). And as it turned out, she didn't speak English either. "No!" she said, and brusquely hung up. What I needed in that moment was the kind of AI call translation feature that's becoming increasingly prevalent

Microsoft AI chief says it’s ‘dangerous’ to study AI consciousness

AI models can respond to text, audio, and video in ways that sometimes fool people into thinking a human is behind the keyboard, but that doesn’t exactly make them conscious. It’s not like ChatGPT experiences sadness doing my tax return… right? Well, a growing number of AI researchers at labs like Anthropic are asking when — if ever — might AI models develop subjective experiences similar to living beings, and if they do, what rights should they have? The debate over whether AI models could on

ChatGPT-5 Lets You Choose Your AI Model. These Are Your Options

The biggest pushback after OpenAI announced its new GPT-5 model for ChatGPT came from devotees of older models who felt the new generative AI chatbot lacked the panache of its predecessors. Now you have more choices of pre-GPT-5 models (although you'll have to hunt for some of them) and better control over which components of GPT-5 handle your questions. OpenAI is still sorting through a somewhat rocky launch of GPT-5, led by complaints about the lack of model choices. The model has been antic
