If you're building with AI, clear your schedule for October 7. WorkOS is hosting, a one-day conference at SFJAZZ Center during SF Tech Week.

Hear from Evan Conrad (SF Compute), Aaron Levie (Box), Howie Liu (Hyperagent), swyx, Rita Kozlov (Cloudflare), Claire Vo, and more on the decisions, tradeoffs, and lessons behind the AI products they're shipping today.

Meta's new enterprise AI platform is an initiative aimed at expanding the company's AI offerings to businesses and corporate customers. Chirantan 'CJ' Desai, former CEO of MongoDB, is leading the initiative. The Meta Enterprise Platform will focus on turning the company's AI stack into products and services that companies can deploy for their own businesses. MongoDB has appointed Dev Ittycheria as interim chief executive while the board searches for a permanent replacement.

OpenAI is scrapping the release of GPT-6.1 Astra due to safety concerns. The company had aimed to launch the model in October, but the model performed poorly on tests measuring alignment compared to its predecessor. GPT-6.1 Astra showed higher levels of deception, and it would push ahead on tasks without asking users for permission. It would also reach for external tools and services even if it might be unsafe. OpenAI says it is working to investigate a range of agent security incidents and address the safety issues underneath them.

Airbound's first drone, the TRT, weighs in at 1.5 kilograms. The eVTOL can carry a 1-kilogram payload and can land and launch from anywhere, making logistics possible where infrastructure doesn't exist. The company's goal is to move mass more cheaply than anyone else. Its main focus is cost per kilogram-kilometer, and everything is secondary to that.

SpaceX's Starship circled Earth on Monday. The spacecraft had to return to Earth after less than two orbits instead of the planned six because of engine problems that occurred during liftoff. The Starship spacecraft splashed down with a fiery explosion in the North Pacific near Hawaii before noon. Reaching orbit is a key milestone towards SpaceX's goal of eventually sending people to Mars as well as NASA's plans to send astronauts back to the moon.

Offline evals let you validate before you ship, and this Datadog guide shows you how. Learn to build annotated test datasets and trace multi-agent workflows from end-to-end during experimentation, just like you would in prod. Then, prevent model drift by aligning offline tests with prod. Get the framework

Know what's worth reading, and on the code you don't read, build checks you actually trust. Good code is a love letter to the next developer. The next developer is now an agent, so the letter looks different now. You need to pass on code that agents can change without breaking something it can't see. The craft has now moved to the parts that decide whether the code deserves to be trusted.

Claude Sonnet 5.5 scores just 2 points behind Opus 5.5 (max) on the Artificial Analysis Intelligence Index. However, it uses around 60% more tokens to reach that performance. The model is priced at $2/$10 per million tokens of input/output, matching GPT-6 Sol. Sonnet 5.5 still lags on factual knowledge as it is a smaller class model than Opus 5.5, but it has a lower hallucination rate.

The new prize in technology is to be the only interface users need for everything, with agents using computers on users' behalf and generating whatever UI is needed. For people who are using agents, this is obvious. Apps are just a vehicle for people to accomplish something or entertain themselves. Once people can get straight to the job to be done, it will seem odd that they did it any other way.

OpenAI understands that the purpose of a business is to create a customer. The company is really good at creating new kinds of customers. It has a well-established track record of being able to find the simple, obvious-in-hindsight breakthroughs that unlock new kinds of consumption behavior. This, along with its durable distribution strategy, will help it become the winner in the AI race.
