☀️ On this day: On September 23, 1889, craftsman Fusajiro Yamauchi opened a small shop in Kyoto, Japan, to make and sell handmade hanafuda playing cards under the name Nintendo Koppai. The cards used pictures instead of numbers, which let them serve as a legal alternative to Western-style cards, then banned in Japan. Today, Nintendo turns 137 and is one of the world's biggest video game companies.

Hand-picked news:

📺 YouTube adds AI agent and video testing tools ↗️LINK

  • YouTube is adding an AI agent that monitors creators’ back catalogs, spots newly relevant videos, suggests title and thumbnail changes, and builds sponsor pitches using channel and audience data.

  • Creators can generate titles and thumbnails, test different images across audience segments, and compare three versions of a video. YouTube can automatically make the highest-performing version permanent after seven days.

  • YouTube says AI should handle efficiency work, not replace creators themselves, but it declined to share evidence that these tools increase views. For now, the clearest promised benefit is saving time.

💸 Anthropic and OpenAI cut AI costs ↗️LINK

  • Anthropic launched Claude Opus 5.5, which tops Artificial Analysis’ Intelligence Index at 58, while OpenAI introduced GPT-6 Sol and Luna with modest performance gains over their predecessors.

  • Both companies focused heavily on cost. Anthropic says Opus 5.5 costs 40% less than Fable 5.1, while OpenAI priced Sol and Luna 50% below the models they replace.

  • Anthropic also targeted Claude’s “Claudish” writing and reported stronger alignment results, while OpenAI prioritized cheaper access. Frontier AI competition now looks increasingly like a battle over price, not just benchmarks.

⌚ Apple is developing a screenless band ↗️LINK

  • Apple is prototyping a screenless fitness band similar to Whoop's, with a thin fabric strap and a sensor module, according to Bloomberg. Apple hasn't committed to launching it, and it wouldn't arrive before 2028.

  • Whoop and Oura now have millions of users each, and services chief Eddy Cue, who took over Apple's health efforts last year, has pushed his team to borrow features from these simpler rivals.

  • Garmin shares fell as much as 2.5% on the news, even though Apple's device remains an internal "technology investigation" that may never actually reach stores.

🧮 OpenAI recruits mathematicians to vet AI discoveries ↗️LINK

  • OpenAI says one internal model has resolved more than 100 open math problems since training began August 28, spanning most branches of mathematics and including its claimed Navier-Stokes breakthrough.

  • Nine mathematicians will advise OpenAI on vetting and releasing results through a Princeton-hosted group. Members receive no OpenAI pay and cannot advise on how quickly the company produces math research.

  • The move follows a letter from 27 Fields Medalists warning AI labs against rushing mathematical results without proper credit or understanding. OpenAI’s challenge now includes reviewing discoveries as quickly as AI generates them.

🧠 Alibaba unveils China’s most powerful AI chip ↗️LINK

  • Alibaba unveiled its Zhenwu V900 AI accelerator, claiming three times the performance of its predecessor and support for massive clusters containing as many as 500,000 chips.

  • CEO Eddie Wu says Alibaba designed the V900 to train frontier AI models, while the company plans a future system with 5 to 10 trillion parameters.

  • Alibaba says its T-Head chip unit has already shipped 560,000 Zhenwu chips to more than 400 external customers. Its planned public listing could turn China’s AI chip race into a much bigger business story.
