For about 11 hours on October 29, Cursor's extension marketplace served a trojanized Claude Code extension under Anthropic's real publisher ID to up to 5,000 users, which means the usual advice to check the publisher could not have caught it.

OpenAI is pulling its models from SpaceX-owned Cursor while Anthropic, which rents $1.25 billion a month of SpaceX compute, promises Cursor more Claude, and the new X Subscription now prices every rival model as an extra.

Karpathy's capability funnel set off a week-long argument about skill, and the measured data from 718 firms, Anthropic's own telemetry and a randomized trial says the scarce skill is verifying output, built from the expertise heavy delegation stops producing.

Two weeks after SpaceX closed its $60 billion merger with Cursor's parent, OpenAI used a change-of-control clause to wind down its model contract by a proposed November 12 shutoff, citing Musk companies' record on contracts and withholding its next model, Astra.

A 110-item infrastructure gatekeeping list that pulled 294K views on X is a verbatim copypasta of a July post with 47 likes, and its 16 headline items grade out at 7 absorbed and 2 still biting against dated platform changelogs.

In twelve days, Chinese labs pushed the capability floor toward zero, Anthropic halved the price of the frontier and Google cut Flash tokens again, a fortnight that says the capability premium is over and margin is the only battleground left.

An Indian vibe-coding startup quintupled its valuation to $1.5B in half a year on a genuine $120M revenue run-rate, leaving open what the multiple is buying when the model underneath is rented and the interface is copyable.

Anthropic shipped Claude Opus 5 as near-frontier intelligence at half the cost of Fable 5, and read from the P&L, the launch is a margin admission that the race has moved from raw capability to cost-per-task.

In 72 hours in early July, SpaceXAI shipped Grok 4.5, Meta shipped Muse Image and Muse Spark 1.1 and OpenAI shipped GPT-Live while GPT-5.6 Sol waited on a government review, and the real frontier, agentic coding at $2 a million tokens, routed straight around that gate.

While Washington spent June turning frontier model releases into licensed events, Meituan open-sourced LongCat-2.0, a 1.6-trillion-parameter agentic-coding model under an MIT license trained entirely on domestic chips, as the counter-move to the export-control regime.

Notion embedded coding agents into its workspace in a few weeks with the Cursor SDK, which turns the harness behind Cursor into a callable runtime so an @mention can plan, build, test and open a PR, a bigger shift than any model release.

At its first Compile conference, Cursor announced a from-scratch model on SpaceX compute, Origin (a GitHub rival), and Cursor Mobile, while its design lead used the stage to warn the result could be slop with working buttons.

Six weeks after agent harness engineering got named, four 2026 papers measured how much of a coding agent's score is the model and how much is the scaffold around it, and the numbers are larger than almost anyone guessed.

The Codex CLI config that ends the permission nagging — config.toml profiles, sandbox and approval modes, AGENTS.md, reasoning effort, MCP servers, and the codex exec setup for CI.

The OpenCode config that earns its keep — opencode.json layers, the build/plan agents, permissions, AGENTS.md, MCP, and the bring-your-own-model setup that survives a vendor pulling your access.

xAI shipped a terminal coding agent, then put a competitor's model inside it that out-codes its own; read against a $60B SpaceX option on Cursor, the CLI war looks less like four rivals and more like one stack assembling itself.
