Every week, I organize 400 to 700 links into roughly 60 categories as part of my ongoing effort to learn about AI. This is my personal notebook, which I enjoy sharing with friends… a hobby and a labor of love, rather than a commercial publication or product.

If you arrived here through a search or shared link, this page collects the links I found for Anthropic for the week ending July 24, 2026.

As part of my learning process, I like to automate the category covers. It gives me a chance to learn Python and APIs.

This week’s cover prompt was written using Claude Opus 4.7, and the image was generated using Gemini 3.1 Flash Image Preview.

Category cover image prompt:

A single glowing parchment scroll unfurling and twisting through deep cosmic purple-black space, its surface rendered as a flowing rainbow ribbon of hot magenta, electric orange, acid yellow, lime, turquoise, and violet, lit from above by a golden mothership beam with chrome starburst sparkles dancing along its curves, with the bold funk display word ANTHROPIC arcing across the top in fat rounded chrome and glitter letters with stacked multicolor drop shadows, 1970s psychedelic Afrofuturist concert poster style, one clear central subject with generous negative space.

This Week in Anthropic News

Here’s a quick AI-generated summary by Claude Sonnet 5.5, based on the headlines and excerpts accompanying this week’s links:

  • Fable 5 access and tooling: Anthropic put Claude Fable 5 into Max and Team Premium plans at 50% of limits, with credits for Pro users. Claude Managed Agents gained per-agent effort levels and webhooks, and Claude Code desktop can now run the iOS simulator beside the conversation.
  • Distillation fight over Kimi K3: A White House official said Moonshot AI distilled Fable to build Kimi K3, and TechCrunch reported that Treasury threatened sanctions. Skeptics, such as Elie Bakouch, noted only 15 days separate the Fable ban removal and K3's release.
  • Fable is not plug and play: Ethan Mollick argued that frontier models are growing more different, so swapping them is harder. He said Opus-era skills can make Fable's output worse, and he judged Fable ahead of Kimi K3 and GPT 5.6 Sol Pro on an Odyssey poem.

This summary was generated by Claude Sonnet 5.5 to help you explore the links below. Rest assured, I select, organize, and check the links by hand in Google Sheets, and write the introduction and personal commentary in The Main Newsletters myself each week as a labor of love.

This reads to me as if preparations are being made to ban models like Kimi K3 in the future. I would be very interested in the evidence that leads to the assumption that Fable 5 was distilled for Kimi K3.”

I have been searching for the most anti-Fable writing. I feel like I need to clear my mind after reading FableProse all day, with its “naming” this & “earning” that. I think it may be John McPhee, non-fiction without pointing at each important thing. And spare & beautiful, too.”

“Generate a fake, but believable, witty Churchill insult at a party and explain the context. It should be very clever and original” This time, I think GPT 5.6 Sol Pro wins, but Fable is good too, and you could argue for it taking the prize. Kimi & Gemini miss by a mile.”

At the moment that everyone is talking about switching models often for cost or sovereignty or optionality or whatever, the most advanced models are growing more and more different from each other. Fable responds very differently than Kimi K3 or Sol, you can’t just plug & play”

Fable, Sol Pro, Kimi K3: “write me a short but good poem using the Odyssey as a basis, think Tennyson or Cavafy” I think this is a Fable victory. Kimi’s is literally a blend of Tennyson’s & Cavafy’s poems themes with some odd bits, and Sol is pretty thematically incoherent.”
https://x.com/emollick/status/2079024884315828351

there are only 15 days between fable 5 ban removal and kimi K3 release. i don’t think claiming that K3’s performance comes from fable distillation (even if they did it) makes sense technically”

Unfortunately for the “distillation = IP theft” theory, raw LLM outputs are not protected by copyright according to the US Copyright Office. Or is this saying that K3 is an infringing copy of Fable? On what basis? (Copyright protection of model weights is not guaranteed either.)”
https://x.com/aviskowron/status/2080000721580364166

A big thing about Fable (and Sol, though a little bit less) is that you need to be really careful about treating it the way you would a less capable model. Skills that worked well for Opus often make Fable outputs worse, and too many lists of negative instructions can do the same”

An issue with Codex and Claude Code is that users need more control over the particular configurations of subagents that orchestrator AIs use. I want to decide whether to delegate research or writing or user testing, and to which models. Otherwise it is a router problem again.”

One of the weird things about AI is some models just turn out to be much better than others and then the next model in line falls back to the mean. A great historical example was Updated Sonnet 3.5 (sometimes called Sonnet 3.6), it was a anomalous jump over what had come before.”
