GOOGLE RELEASES GEMINI 3.8 FLASH, ITS THIRD FLASH MODEL IN SIX WEEKS

Google has released its third Flash model in just six weeks in two variations. The standard model is good for agentic tasks and software development, while the Cyber model has been tuned for vulnerability detection and mitigation. The Cyber model is currently limited to trusted testers and governments. API access to the model is available at an introductory rate of $0.75 per million input tokens and $3.75 per million output tokens through until the end of the year.

THE RACE TO ENGINEER NEW KNOBS FOR THE HUMAN BRAIN

Chemogenetics is a powerful technique that modifies specific neurons so they can be controlled remotely by normally inert drugs. There are several ongoing clinical trials of chemogenetics in China. The research could result in new ways of treating epilepsy, Parkinson's disease, and pain. This post looks at chemogenetics, describes what those first clinical trials are doing, and looks at how they could be improved upon.

ROBOTAXIS TRY THEIR LUCK ON LONDON'S MEDIEVAL ROADS

The arrival of 15 robotaxis in London is an important step for the autonomous vehicle industry. Acceptance of the technology has been slower in European cities, where the driving environment can be complex, and regulation is stiff. The failure rate of a driver's license test in London is just over 50%. 15 cars will be available for ride-hailing through Uber's app during the safety testing period.

HOW WE MAKE AI CODING MORE COST EFFICIENT WITHOUT SACRIFICING TASK QUALITY

Token count alone isn't a meaningful measure of efficiency. The goal should be to use the right amount of context to move a task forward. Concise tool responses can sometimes require additional calls or work if they leave out information agents need. This ultimately makes tasks slower and more expensive, which is why it is important to optimize for the outcome rather than the tool call.

AI PRODUCTIVITY DOESN'T MEAN WHAT I THINK IT MEANS

One-shot prompt templates often fail. The current best working architecture is a closed-loop taste flywheel. AI raises the ceiling of what the same effort produces. Users should push for the higher-quality output AI now makes possible rather than just accepting the pre-AI baseline.

IN A BIG WIN, GOOGLE AVOIDS A BREAKUP OF ITS AD TECH BUSINESS

A federal judge has ruled that Google must make changes to its advertising business but will not have to break it up. The ruling will ensure that Google's power over the internet will remain largely unchanged. Google has been ordered to change its business practices to benefit competitors, but no specific instructions have been provided. The ruling is another sign that the federal government's attempts to rein in the power of big tech have faltered.

HOW TO PROTECT YOURSELF FROM WORKSLOP

Workslop is when your co-workers or managers communicate via big chunks of copy-pasted AI-generated text. The core problem with workslop is that the effort involved is asymmetrical. It costs almost no effort to produce slop, but it still costs effort to read. This post looks at different ways to handle this workslop so that you don't waste ten minutes of effort for every ten seconds of theirs.

UBER CUTS 10% OF EMPLOYEES IN SWEEPING REORGANIZATION

Uber is laying off around 3,300 people to create a leaner organization with clearer leadership, faster decisions, and more time spent building rather than coordinating.

MAKING THE INTERNET BORING
