Anthropic paused Agent SDK billing after agents hit the price list

Anthropic paused its June 15 plan to move Claude Agent SDK, claude -p and some third-party agent use into a separate credit pool. Teams running automations get a short reprieve, not a settled answer on long-running agent costs.

SpaceX buys Cursor for $60 billion and enters enterprise AI through developers

SpaceX is buying Anysphere, the maker of Cursor, in a deal valued at $60 billion, according to The Verge and Bloomberg. Musk is aiming at enterprise AI through a tool developers already use to write production code, not through another standalone chatbot.

ChatGPT fell to 46.4 % share as Gemini and Claude gained ground

Sensor Tower says ChatGPT's share of the AI assistant market fell to 46.4 % by the end of May, even as it still has more than 1.1 billion monthly users. The bigger story is market fragmentation, where Google's distribution and Claude's paid conversion are starting to matter.

Anthropic hit an export brake that shut Fable 5 off for every customer

Anthropic says US officials ordered access to Fable 5 and Mythos 5 suspended for foreign nationals, so the company disabled both models for all customers. Buyers of frontier AI now have to price in a risk that sits outside the model: the state kill switch.

The US move against Fable and Mythos takes the same blade from defenders and attackers

The US government told Anthropic to restrict Fable 5 and Mythos 5 for all foreign nationals, so Anthropic switched the models off for all customers. A protest by 76 security experts exposes the weak point: export control is bad at separating an offensive exploit from defensive testing.

Claude Opus 4.8 sells judgment, not just another benchmark

Anthropic released Claude Opus 4.8 at the same standard price as Opus 4.7, with a focus on coding, agentic tasks and longer work. The more important shift is a model that is supposed to say more often when it is unsure.

The Mythos suspicion turns export control into an access control problem

The Verge, citing Semafor, says the White House restricted exports of Anthropic Mythos partly over suspicions that a China linked group had access to it. For AI labs, the warning is blunt: frontier model security is not just about public APIs, but every path to access.

Claude Fable 5 turns safety into a question of access to the best model

Nathan Lambert reads the Claude Fable 5 release as a dispute over who gets to use a frontier model without routing and filters. The important layer is not only model capability, but the governance system that decides when the user is really talking to the strongest model.

Agent cost is no longer a footnote. It is an engineering expense

Simon Willison shows how he manually added pricing for Claude Fable 5 in AgentsView and immediately saw the cost of local coding agents by project. The small trick points to a bigger shift: AI coding is starting to look like infrastructure consumption, not an app subscription.

datasette-agent-edit tackles the boring part of agents: safe text edits

Simon Willison released datasette-agent-edit 0.1a0, a base plugin for Datasette Agent with view, str_replace and insert tools. It is not a flashy AI demo. It is the layer that decides whether an agent can edit text without casually breaking the file.

Zvi’s AI week shows why one grand narrative is not enough

Zvi Mowshowitz's AI #171 is not one clean trend, but a signal map: Claude Opus 4.8, US frontier model testing, OpenAI's policy blueprint and PAC politics.

A service worker intercepts HTTP requests and handles them in a Python ASGI app running entirely in the browser

Simon Willison experiments with running Python ASGI apps directly in the browser using Pyodide and a service worker. FastAPI and a complete Datasette 1.0a31 both ran successfully. The point is distribution: demos or data tools as self-contained web pages without a server.

Opus 4.8 misses code flaws four times less often and introduces mid-conversation instruction updates

Anthropic shipped Opus 4.8 with one concrete metric: the model is four times less likely to miss code flaws than its predecessor. It also adds mid-conversation system messages and reduces the minimum prompt cache size from 4,096 to 1,024 tokens.
