OpenAI announced on 8/28 that it is winding down its contract to supply models to Cursor, triggered by a change-of-control clause after SpaceX acquired the coding editor. The proposed shutoff date is 2026-11-12, about 10 days from now. After that, Cursor users will need their own OpenAI API key (BYOK) to keep using GPT models, and OpenAI says future models like GPT-6.1 Astra won't be offered to Cursor at all. OpenAI cited Musk-owned companies' history of breaking contract terms as its reasoning; Cursor's CEO responded that OpenAI models account for only about 5% of its traffic and that the two companies are still talking.
Cursor switched new-signup pricing to The X Subscription on 10/12: Free, Plus $8 (Grok only), Premium $30, Super $100, Ultra $200. The old $20 Pro plan is grandfathered for existing subscribers only. New users who want Claude/GPT/Gemini now need Premium at $30 (up 50% from Pro's $20); third-party model token rates are unchanged, still billed separately at API list price.
pstack is an MIT-licensed set of agent skills from Cursor engineer Lauren Tan. One entry point, /poteto-mode, picks one of 23 playbooks per task and calls other skills and 24 principles as steps need them. Install takes one command and one model setup; the price is extra tokens for subagents and review panels.
Cursor engineer Lauren Tan (poteto) says she merges roughly 2,000–2,500 PRs a month, a self-reported figure no one has audited. Her method is three moves: build a verification skill first, turn repeated mistakes into lint and type constraints, and sample-review after merge. The method transfers if your domain can be verified by code.
Nine coding agents have taken at least four different paths for long-term memory: Claude Code and Codex use Markdown files (agent-written, human-readable), Antigravity CLI inherits Gemini CLI's approval inbox (agent proposes, human decides), and Copilot uses citations with JIT verification (auto-deleted after 28 days unverified). Cursor removed its Memories feature and fell back to human-written Rules. Hermes Agent, OpenClaw, and Letta Code treat memory as a core harness component, not a plugin. Their choices on write timing, forgetting, and cross-team sharing are completely different — and none has published a controlled experiment on whether their memory system actually helps.
The local products post (order 6) of the Sandbox Series. How OpenCode, Codex CLI, Cursor and other CLI agents and IDEs set up local sandboxes, where the isolation boundary lies, common pitfalls, and security best practices.
BytePlus ModelArk Coding Plan offers Lite ($10/month) and Pro ($50/month) subscriptions covering models such as DeepSeek-V4, GLM-5.2, and Seed-2.0 in tools including Claude Code and Cursor. Lite includes about 24,000 requests per month; Pro includes five times as many.
Agent Plugins 1.0 is a packaging format that bundles Agent Skills (markdown instructions) and MCP server configs into a single directory, loadable by ChatGPT, Cursor, GitHub Copilot, Kiro, and VS Code. It's not a new protocol — it's the wrapper above protocols. Vercel initiated it, OpenAI/AWS/Microsoft/Cursor co-authored it, and Google joined on launch day. Anthropic isn't on the governance board, but MCP is a core primitive of the spec.
AI agents can operate video generation tools through three approaches — Skills, MCP Connectors, and direct APIs. Choosing the right integration method matters more than choosing the right tool.
Spin up a local OpenAI-compatible endpoint at localhost:20128 that automatically routes requests from Claude Code / Cursor / Cline / Codex / Copilot through a Subscription → Cheap → Free 3-tier fallback to 40+ providers. Built-in RTK compresses tool_result (saving 20–40% input tokens), Caveman mode compresses output, OAuth auto-refresh, multi-account round-robin — install with npm install -g 9router and two commands.
Cursor CLI brings the IDE agent to the terminal with an interactive TUI and headless mode, Plan/Ask/Agent modes, Cloud Handoff, and CI/CD integration. Billing now runs on two separate usage pools: Cursor's own models (Grok 4.6/4.5, Composer 2.5) and third-party models (Pro includes $20, Pro+ $70, Ultra $400).
A comparison of six agent CLI subscriptions (Claude Code, Cursor CLI, Codex, Kiro, Antigravity/Gemini CLI, OpenCode) plus the multi-model routing pattern — cheap models for simple work, strong models for hard work. Nearly every one of these changed its billing in the first half of 2026; this version was re-verified on 8/18.
