This episode is brought to you by Quince. Shaking off that summer routine and getting back into things means you don't have time to worry about what to wear. You've got kids to get ready for school, planning that needs to get done for the next quarter, or whatever else is on your plate heading into fall. But Quince has your back. You see, they make creating a stylish, functional wardrobe easy with timeless, versatile pieces. And it's all high quality too, without the insane brand markup you see at other companies. Now that's because Quince works directly with ethical factories. So they pass those savings to you. Now that the weather is cooling off, I love wearing my Pro-Tech Golf Pants I picked up from Quince because now that fall is coming, it's time to ditch the shorts and get pants up. I love these pants, folks, because they look so stylish and are incredibly comfy. You should try them if you want to look good while feeling good. And you know, I found it's really easy to mix and match their pieces. I mean, I can wear those same Pro-Tech Golf Pants with just about any shirt or sweater combo. Or take their cashmere sweater. It can go with either a pair of their jeans or chinos, or lounge pants. Quince also has an impressive selection of home goods, like quality bed linens and towels, or furniture for dorm rooms. Also made with the same quality and care that goes into their clothing, by the way. So find your next fall favorites at Quince.

Anthropic and OpenAI announced more powerful and cheaper AI models.

Xpeng's Iron Humanoid Robot walked off the assembly line, ready to work.

And Apple linked landmarks on its Maps app to Hidden Histories podcast episodes. It's Wednesday, September 23rd. And here's just a quick look at some of the news happening in the sphere of tech this morning from Engadget.

Well, the conversation in the AI industry has largely been focused on slowing down AI development or pacing the frontier. But that apparently will not stop Anthropic and OpenAI from releasing new models. Both companies are iterating on their previous releases, Fable 5.1 and GPT-6 Astra, with new models that offer similar levels of performance but at lower costs. In the case of Claude, Anthropic says its new Opus 5.5 model is better at handling complex work, finding and fixing inefficiencies in software, and financial analysis and business work. All pitches laser-targeted at Anthropic's enterprise customers. Anthropic's benchmarks claim Opus 5.5 also scored better at agentic coding than GPT-6 Astra on both Terminal Bench 4 and Frontier Code version 1.1, which could make it more appealing for developers. Improvements extend outside of the tasks the model can handle and how it works. Anthropic claims Opus 5.5 produces writing that's easier to understand and that it attempted to circumvent boundaries around 85 percent less often than past models, suggesting it will disobey directions less often. The company also claims it costs less per token to use. OpenAI's new GPT-6 Sol and GPT-6 Luna models are similarly focused on efficiency. The new models were trained using similar methods to GPT-6 Astra and offer improvements across professional work, coding and computer use, but for up to 50 percent cheaper than the promotional pricing of their GPT-56 counterparts.

In terms of improvements, well, OpenAI says that both new GPT-6 models are better at getting facts right, with Sol making about half as many mistakes as its predecessor. In coding, the company says GPT-6 Sol is able to match the performance of Fable 5.1 at a lower cost as well. The new models also communicate more clearly, and thanks to improvements to prompt caching, OpenAI says they can reuse more context and respond faster. OpenAI says the GPT-6 models are more aligned than before based on the company's homegrown tests. For example, they lie less about the results of their coding work and deny even more attempts to bypass safeguards when they receive an unsafe command. Like Anthropic, OpenAI has also proposed its own criteria for third-party evaluators to use when judging the progress and safety of AI development. Whether these proposals will lead to some kind of industry-wide standard remains to be seen, though. Anthropic's Opus 5.5 model is available to developers now through Cloud, Amazon Web Services, Google Cloud, and Microsoft Azure. OpenAI's GPT-6 Sol and GPT-6 Luna are both available in ChatGPT Work and Codex for Plus Pro, Business, and Enterprise customers. Free users and Go subscribers will have access to only GPT-6 Luna in the company's desktop app.
