Ben’s Bites publishes a wide-ranging AI industry roundup and a personal note from Ben.

Big headlines

Kimi K3 from Moonshot AI is said to beat Fable and GPT-5.6-Sol on Arena’s frontend coding leaderboard, while being half the price per token but twice as token-hungry as Sol. It supports images and a 1M-token context window, and its weights are promised open by July 27. New subscriptions are paused because of GPU shortages.
Fable 5 is now included in Claude’s Max and Team plans, and the model is also credited with disproving the 87-year-old Jacobian conjecture.
Sierra’s Horizon is pitched as agents that work toward business outcomes over days or months, spanning calls, texts, email, and internal systems, with pricing tied to outcomes rather than tokens.
NotebookLM has been renamed Gemini Notebook and now has Collections to organize notebooks.

Quick links and product notes

Cursor reportedly rebuilt SQLite from an 835-page manual with multiple agent-swarm setups, with costs ranging from $1,339 to $10,565 depending on the model combo.
Notion AI now has browser access in early access.
Ramp Router sends each request to a relevant model and reportedly saves 30% internally.
Other mentions include OpenShip, Lucy 2.5, Linear Loops, Rivet, Hilos, tldraw offline, and self-driving-company writeups from Replit and Gumroad.

The issue reads like a fast-moving snapshot of the current AI product and company landscape.
