GPT-6 Astra needs leaner prompts and fewer guardrails, OpenAI recommends

Overly long skill descriptions, blanket reading requirements, and rigid approval rules can get in GPT-6 Astra's way, warns OpenAI's Eric Provencher. More capable models need less hand-holding, so developers should tie instructions to specific tasks and spell out when the job is done.

So you want to use OpenRouter?

So you want to use OpenRouter? One of OpenRouter's selling points is that it "handles fallbacks automatically and picks the most cost-effective option for each request", so you can call a single API endpoint for a model and get routed to the best available backend provider. Mohamed Moustafa points out a whole set of ways that this can cause you problems. Different providers run different serving software with different optimizations and settings, which means that the same OpenRouter endpoint can serve model requests that behave in different ways. Some providers even lack vision capability for vision models, and the way the reasoning effort option is processed can differ as well. Thankfully you can control which provider is routed to using the provider.only option . The /endpoints method returns the list of available providers for a specific model ID.

SMAC CEO: Women’s Sports Is an Untapped Market

Constance Schwartz-Morini, cofounder and CEO of SMAC Entertainment, joins the program to discuss how the business of sports has shifted from simple endorsement deals to the “athlete as an enterprise” model. Schwartz-Morini notes that athletes once viewed a Nike or Wheaties deal as the peak of commercial success, but now many can generate income through owned media, consumer brands, licensing, and intellectual property. She speaks with Romaine Bostick on "The Close." (Source: Bloomberg)

What Anthropic Doomsayer Jacob Coxon Saw

Yesterday, Amir and I examined the shock waves that have rippled through the AI industry and far beyond since former Anthropic researcher Jacob Coxon very publicly quit his job over concerns that AI “could kill us all”—and another Anthropic AI safety specialist put the probability of such a catastrophe at greater than 10%. Coxon told me that is hardly the most pessimistic view inside Anthropic. “People have varying probabilities that—barring some substantial coordinated slowdown—the whole thing ends in doom,” he said in an interview later Wednesday. Those estimates range higher than 50% among some Anthropic employees, he said. Coxon was able to gauge the fears of his fellow employees because “Anthropic has a substantially more transparent internal culture than OpenAI,” where Coxon worked for years before joining Anthropic in May. Coxon, who focused on the earliest stages of training AI models at Anthropic, said he decided to leave the company because he was gradually “starting to viscerally feel the fear of where the tech's going to be like the next two years or even the next one year.”

Introducing GPT-6 Astra for developers

Introducing GPT-6 Astra for developers Blink and you'll miss it, but there's a familiar creature at 1m59s : Across the board, Astra has more attention to detail, better understanding of the user's prompt, and can build more sophisticated outputs. In particular, it excels at building 3D models. I've seen it make incredible renderings of gardens, shipyards, animals , cityscapes, even Dyson spheres. Astra really does believe in putting a red neckerchief on a pelican riding a bicycle. Via Hacker News comment Tags: ai , openai , generative-ai , llms , pelican-riding-a-bicycle , gpt-6-astra

OpenAI's new Agents API gives developers the infrastructure behind Codex and ChatGPT

OpenAI is releasing the Agents API as a public beta. It lets developers build cloud agents that run autonomously for hours, execute code, and hand off tasks to sub-agents. There are no extra fees beyond token usage. Cloudflare, Vercel, and Oracle offer additional sandbox environments.
