OpenAI has released the GPT-5.1 family of models. GPT-5.1 Instant is a high-volume model that uses adaptive reasoning - it can decide when to think longer on hard prompts. GPT-5.1 Thinking can vary its deliberation for each question, so simple tasks are faster and complex work gets deeper analysis. GPT-5.1 Auto routes queries between models. ChatGPT has gained stronger personalization controls - users can now pick between different personalities.

The Steam Frame is a new wireless VR headset with pancake optics, a 110-degree field of view, and inside-out tracking. It will not require a gaming PC to work. The Steam Machine is a more powerful but less portable follow-up to the Steam Deck designed to fit into a standard-sized shelving unit to connect to a display. The Steam Controller is designed to replace a mouse. All of the new products will be released in 2026. No prices have been announced yet.

Waymo has started offering robotaxi rides on freeways for customers in Los Angeles, Phoenix, and the San Francisco Bay Area. It is the first company to offer fully autonomous freeway rides without a human specialist in the car to fare-paying riders in the US. Freeways are more controlled environments in some respects, but the higher speed poses a much higher risk. Cars need to be able to predict what happens much farther down the road. Waymo has announced plans to more than double the number of cities it operates in.

Dark excitons are exotic light-matter states found in atomically thin semiconductors. They usually remain invisible because they emit light very weakly. Researchers have found a way to make these previously hidden light states shine brightly and controllably. This discovery opens up a new frontier for faster, smaller, and more energy-efficient technologies.

Creativity is not like productivity - you can't just work harder and expect creativity to appear. Sprinkle in new inputs instead, and see what new outputs appear. This post lists 12 inputs that help increase creativity.

Coinbase plans to leave Delaware and reincorporate in Texas because Texas' legal framework is more predictable and efficient. Delaware has long been the legal home of most big companies in the US, but the state's courts appear to be biased against founders and their boards. Texas has capitalized on executives' frustrations with Delaware by establishing the Texas Business Court and passing laws to make it more difficult to sue board members at companies incorporated in Texas and more challenging for shareholders to file stockholder proposals against companies.

Software engineering isn't a formal club - if you do the work, you get to say you did the work.

Template interpreters generate machine code for each bytecode op handler and create an instruction dispatch table that maps bytecode opcode to machine code to execute it, allowing developers to do interesting things like keep important/hot variables in dedicated registers or use the hardware call-stack instead of simulating the stack.

Making art for a living requires running a business, usually alone.

OpenAI reportedly spent $8.7 billion serving its models on Microsoft Azure alone in the first three quarters of 2025.
