Writing a storage engine for Postgres: an in-memory Table Access Method

With Postgres 12, released in 2019, it became possible to swap out Postgres's storage engine. This is a feature MySQL has supported for a long time. There are at least 8 different built-in engines you can pick from. MyRocks, MySQL on RocksDB, is another popular third-party distribution. I assume there will be a renaissance of Postgres storage engines. To date, the efforts are nascent. OrioleDB and Citus Columnar are two promising third-party table access methods being actively developed. Why

Tesla exec leading development of chip tech and Dojo supercomputer is leaving company

Tesla's vice president of hardware design engineering, Pete Bannon, is leaving the company after first joining in 2016 from Apple , CNBC has confirmed. Bannon was leading the development of Tesla's Dojo supercomputer and reported directly to Musk. Bloomberg first reported on Bannon's departure, and added that Musk ordered his team to shut down, with engineers in the group getting reassigned to other initiatives. Tesla didn't immediately respond to a request for comment. Since early last year,

Achieving 10,000x training data reduction with high-fidelity labels

Classifying unsafe ad content has proven an enticing problem space for leveraging large language models (LLMs). The inherent complexity involved in identifying policy-violating content demands solutions capable of deep contextual and cultural understanding, areas of relative strength for LLMs over traditional machine learning systems. But fine-tuning LLMs for such complex tasks requires high-fidelity training data that is difficult and expensive to curate at the necessary quality and scale. Stan

GPT-5: Key characteristics, pricing and system card

GPT-5: Key characteristics, pricing and model card I’ve had preview access to the new GPT-5 model family for the past two weeks (see related video) and have been using GPT-5 as my daily-driver. It’s my new favorite model. It’s still an LLM—it’s not a dramatic departure from what we’ve had before—but it rarely screws up and generally feels competent or occasionally impressive at the kinds of things I like to use models for. I’ve collected a lot of notes over the past two weeks, so I’ve decided

OpenAI’s GPT-5 is here

OpenAI has launched GPT-5, a new flagship AI model that will power the company’s next generation of ChatGPT. GPT-5, which was released Thursday, is OpenAI’s first “unified” AI model and combines the reasoning abilities of its o-series of models with the fast responses of its GPT series. The next-generation model signals a new era for ChatGPT — and its creator, OpenAI — pointing to OpenAI’s broader ambitions to develop AI systems that are more like agents than chatbots. While GPT-4 enabled AI c

High costs and thin margins threatening AI coding startups

In February, AI coding startup Windsurf was in talks to raise a big new round at a $2.85 billion valuation led by Kleiner Perkins, at double the valuation it hit six months earlier, sources told TechCrunch at the time. That deal didn’t happen, according to a source familiar with the matter. Instead, news broke in April that the startup planned to sell itself to OpenAI for roughly the same valuation: $3 billion. While that deal famously fell apart, one bigger question remains: If the startup was

OpenAI's new open-source model is basically Phi-5

OpenAI just released its first ever open-source large language models, called gpt-oss-120b and gpt-oss-20b. You can talk to them here. Are they good models? Well, that depends on what you’re looking for. They’re great at some benchmarks, of course (OpenAI would never have released them otherwise) but weirdly bad at others, like SimpleQA. Some people really like them. Others on Twitter really don’t. From what I can tell, they’re technically competent but lack a lot of out-of-domain knowledge: fo

Very Important Study Calculates Your Chance of Being Killed by an Asteroid vs Several Other Scary Things

In what first appears like a rather morbid game of “which would you rather?”, researchers have released a new study that games out how likely the average person is to die should one of various mishaps like car crashes, carbon monoxide poisoning, and lightning strikes, occur—or because a giant asteroid destroys the Earth. The probability of a planet-annihilating asteroid crashing into Earth is low, but it’s not zero. In fact, Earth had a recent close call when a newly discovered asteroid was cal

Roblox Rolls Out System to Spot Child-Endangerment Chat Messages

Roblox is a popular online gaming platform for children. But it's also a place where people who want to exploit children know they can find an audience. On Thursday, Roblox announced Roblox Sentinel, an artificial intelligence system that's designed to flag inappropriate messages in its chat feature. Roblox already prohibits sharing real-world images and personal information, like phone numbers and usernames. The company hopes Sentinel will flag more messages sooner for investigation. It's been

ChatGPT's GPT-5 models released: everything you need to know

After a long wait, GPT-5 is finally rolling out. It's available for free, Plus, Pro and Team users today. This means everyone gets to try GPT-5 today, but paid users get higher limits. In a blog post, OpenAI says GPT-5 is a big leap compared to previous models. OpenAI added that GPT-5 is the best coding model, and early benchmarks suggest it beats Opus 4.1 from Claude by a small margin, but real-life benchmarks are awaited. Unlike previous models, GPT-5 has built-in reasoning. It is a unifie

Did a rival tribe kill and eat their neighbors 5,700 years ago?

Credit: IPHES-CERCA/Luis Quevedo/Madrid Scientific Films. Human remains from 11 individuals recovered from El Mirador Cave in Spain showed evidence of cannibalism, archaeologists have concluded. According to a new paper published in the journal Scientific Reports, the cannibalism was likely the result of a violent episode between competing Late Neolithic herding communities about 5,700 years ago. “Cannibalism is one of the most complex behaviors to interpret, due to the inherent difficulty of

OpenAI launches new GPT-5 model for all ChatGPT users

"GPT-5 has been trained to recognize when a task can't be finished, avoid speculation and can explain limitations more clearly, which reduces unsupported claims compared to prior models," said Michelle Pokrass, a post-training lead at OpenAI. Instead of outright refusing to answer users' questions if they are potentially risky, GPT-5 will use "safe completions," OpenAI said. This means the model will give high-level responses within safety constraints that can't be used to cause harm. OpenAI s

GPT-5 is here. Now what?

Whereas o1 was a major technological advancement, GPT-5 is, above all else, a refined product. During a press briefing, Sam Altman compared GPT-5 to Apple’s Retina displays, and it’s an apt analogy, though perhaps not in the way that he intended. Much like an unprecedentedly crisp screen, GPT-5 will furnish a more pleasant and seamless user experience. That’s not nothing, but it falls far short of the transformative AI future that Altman has spent much of the past year hyping. In the briefing, A
