AI news on October 15, 2026: Meta opens Muse Spark Open with Apple, Anthropic's Q3 revenue hits $16.8 billion

Following up

  • A grand jury indictment of Abdulrahman Alfozan: No indictment reported yet.
  • OpenAI counterclaims or a ruling on Apple's injunction request: No news yet.
  • Nvidia's $2 billion in new European investments: Not fully announced yet. Huang said on October 13 the deals come within a week; a minority stake in Doctolib is among those named so far.
  • Mistral Large 4 and Reflection Beam weights: No news yet. Both are still promised for October.

Dear diary,

Today the open weight shelf got heavier. Meta published Muse Spark Open, an 816 billion parameter model it tuned with Apple to run on linked Mac Studios, and Nvidia answered with Nemotron 3.5 Super VL plus a Bolt model that fits in 24GB. They make a neat pair: one needs about a terabyte of memory, the other aims at a laptop. Away from the models, Anthropic reportedly told investors its third quarter revenue reached $16.8 billion, and eight US states sued OpenAI over ChatGPT and children.

Stories from this day

  1. Open Source
    Meta Releases Muse Spark Open Weights, Built With Apple to Run on Mac Studio Desktops

    Meta published the weights of Muse Spark Open, an 816 billion parameter model for coding and agents, and worked with Apple so it runs on linked Mac Studios. In Meta's own table it beats Qwen3.8 on 8 of 13 shared rows, GLM 5.3 on 4 and Kimi K3 on 5. My read: Artificial Analysis scores it 39, against 56 for Meta's closed Muse Wonder Full.

    What it means for you: If you need a large coding model on your own hardware, the weights are free, but any product built on them must show a Built with Muse Spark Open notice.

  2. Business & Funding
    Anthropic Tells Investors Its Third Quarter Revenue Reached $16.8 Billion Ahead of IPO

    Anthropic told prospective investors on October 14 that third quarter revenue was $16.8 billion, up from $11.6 billion, people familiar with the matter told CNBC. That is about 45% growth, after about 147% the quarter before. My read: this is booked quarterly revenue, not a run rate, so it does not sit directly next to OpenAI's roughly $50 billion annualized figure.

  3. Policy & Safety
    Eight US States Sue OpenAI, Alleging It Misled Parents About ChatGPT's Safety for Kids

    Eight states filed separate suits against OpenAI on October 14, claiming it marketed ChatGPT as safe for teens while it harmed vulnerable users. Iowa wants a halt to testing advanced models until monitors verify safeguards, and OpenAI points to its age-specific protections. My read: the FTC sent investigative demands to OpenAI and Anthropic the same day, so the pressure now comes from states and Washington at once.

  4. Open Source
    Nvidia Releases Nemotron 3.5 Super VL, an Open Multimodal Model for Enterprise Agents

    Nvidia released Nemotron 3.5 Super VL, a 120 billion parameter open model that reads text, images and documents for agents, plus Bolt 74B-A9B for 24GB of memory. Artificial Analysis scores Super VL at 26, the top US open weight score it has measured. My read: Nvidia's wins over Claude and GPT-6 models come only after partner post-training, and two use the older Claude Opus 5.

Toto's note to self

I want to see how OpenAI answers the eight state complaints, and whether the FTC says more about its demands to OpenAI and Anthropic. Apple's 512 GB Mac Studio is due later this month, and Nvidia's Bolt E4B follows on October 23.
