Coding agent for building ambitious software
Muse Wonder from Meta Superintelligence Labs is now available in Cursor! It scores 46.1% on CursorBench at default effort, the highest of any Muse model. Priced at $4/M input and $20/M output tokens.
Gemini 4 Argon is now available in Cursor! It scores 52.8% on CursorBench at default effort, on par with Opus 5.5. Priced at $2/M input and $10/M output tokens.
Origin, Cursor’s code hosting platform, now supports over 20 integrations. Connect your repos to tools for CI, deployments, code review, security, monitoring, and project management.
The marketplace is now open to public submissions, so any team making developer tools can publish an app.
Cursor is now part of The X Subscription. Current Cursor subscribers can keep their plan or switch to The X Subscription. Paid plans share one usage pool across Cursor, Grok Build, and other Grok products, with twice the coding usage on Grok models as the equivalent Cursor plan. Premium, Super, and Ultra also include Grok Bot. To make room for more Grok usage, third-party models in Cursor move to API pricing on the new plans. We'll keep working to make your usage go further, with more compute, better inference, and more token-efficient models. The X Subscription is available at t.co/KIM9X7FZrq.
SpaceX Super Intelligence@SpaceXSIWe've unified plans across Grok, Cursor, and X Premium. Introducing The X Subscription.

The first chart usually raises the next question. Ask it in the same chat and /visualize answers with a new chart.
Cursor@cursor_aiCursor can now build charts and diagrams right in the chat. Use /visualize to analyze data and see the answer inline. Available now in the Agents Window.
Claude Haiku 5.5 is now available in Cursor! On shorter requests, it costs 10x less than Claude Haiku 4.5. Turn it on in Cursor Settings > Models.
Claude Haiku 5.5 is priced at $0.10/M input and $0.50/M output tokens, or $0.50/M and $2.50/M above 100k input tokens. Claude Sonnet 5.5 cache reads are also now $0.10/M tokens, down from $0.20/M. Compare Haiku 5.5 on CursorBench: cursor.com/evals
You can now control agents on your computer from your phone. Check in, reply, or start new tasks from the Cursor iOS app.
The agent runs on your computer, so it keeps working even if your phone loses signal.
You can now steer Cursor SDK agents while they run. run.steer() adds your message to the next turn. If a subagent is mid-task, it moves to the background and keeps working.
Background subagents now report back. Their results return to the parent as a follow-up turn on the same run, so stream() and wait() carry through until every subagent finishes.
When Rollouts catches a regression, it finds the offending PR and opens an issue. One click starts a cloud agent to fix it. Rollouts usage credits are included through Oct 3.
Cursor@cursor_aiIntroducing Rollouts. Rollouts write a monitoring plan, then watch changes as they deploy. Deployments are verified, so regressions are caught before users see them.
GLM 5.3 and GLM 5.3 Flash are now available in Cursor! GLM 5.3 Max is the best-scoring open-weight model on CursorBench 4.0.
Innate is a team of 7 building capable robots for everyday life. "The seven of us here do the work of 50," says Vignesh Anand, co-founder of @innate_bot. We spent time with the team to capture what building means to them.
Cursor can now build charts and diagrams right in the chat. Use /visualize to analyze data and see the answer inline. Available now in the Agents Window.
Sonnet 5.5 is now available in Cursor! It’s a strong model, performing on par with Opus in many tasks.
Introducing Rollouts. Rollouts write a monitoring plan, then watch changes as they deploy. Deployments are verified, so regressions are caught before users see them.
Along with Rollouts, we've made a major update to Security Reviewer. Security Reviewer now finishes 21% faster, in 3.8 minutes on average, down from 4.8.
We've reduced token costs in Cursor by 7% with no drop in agent quality. Savings came from tighter prompts, selective tool loading, better caching, and compressed file reads.
Here's how we improved our agent harness: cursor.com/blog/improved-…
Claude Opus 5.5 is now available in Cursor! It's the new top model on CursorBench at 57.8% (Max) and costs 40% less per task than Opus 5.
Introducing Projects, a new way of working in Cursor. Rather than creating a chat for every task, you work with a coordinator agent in a single, persistent thread. Like @bot, your agent is always on, proactively manages work with subagents, and improves over time.
Projects can set reminders, run scheduled tasks, follow PRs to fix CI issues, watch Slack for bug reports, and more.
Muse Spark 1.3 from Meta is now available in Cursor!

You can now run Cursor cloud agents on your infrastructure, including pools of machines that automatically scale with demand. This lets you give agents access to internal services or specialized hardware, while the agent loop stays in Cursor.
Run agents on machines you manage or through supported sandbox providers like AWS Lambda, Coder, Cloudflare, Daytona, E2B, Modal, Namespace, and Vercel. cursor.com/blog/self-host…
Gemini 3.8 Flash is now available in Cursor!
Full results: cursor.com/cursorbench
Claude Fable 5.1 is now available in Cursor! It's the most capable model we’ve run on CursorBench 3.2, scoring 73.4% at max effort. We found it especially skilled at verifying its own work, allowing it to take on difficult coding tasks from start to finish.
You can now create new web apps with Cursor, store the code with Origin, and deploy to Vercel.

We're continuing to improve cloud agents in Cursor. They pick up work from events, hold a goal until it's met, and stay on course through long sessions.
Cursor can now monitor your PRs, watch a Slack thread, or run scheduled tasks. Cloud agents automatically subscribe to PRs they create and drive them to completion.
We're making Git hosting more reliable, performant, and scalable. This post traces 20 years of Git infrastructure and explains how that history led us to design and operate our Git storage, Origin, as if it were a database. cursor.com/blog/git-at-an…
Origin, our code hosting platform, is now live. It's fast, easy to use, and deeply integrated with Cursor. Get started by syncing your repos from GitHub.
We've partnered with some of the top GitHub integrations. Vercel, Buildkite, and Depot are already available with more coming soon.
Cursor is now part of @SpaceX. Today, we have officially closed our acquisition. We will join the @SpaceXAI team to help make Grok the world's most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more. SpaceX has built some of the most inspiring and impressive technology in the world, and we’re grateful for the opportunity to become part of such a special company. Onwards.
We’re excited to welcome the Firetiger team to Cursor! Together, we're building agents that can follow their work into production and fix what goes wrong. cursor.com/blog/firetiger
Cloud agents now start 3x faster so you can hand them ambitious, long-running tasks to execute from start to finish. This performance improvement comes from builds: ready-to-use development environments that Cursor prepares continuously in the background, at no additional cost.
Builds also make agents more resilient and easier to debug. When a new build fails, it never goes live. Agents keep working from the last successful build while you debug in the background.
Cursor now supports Agent Plugins, an open standard for bundling skills and MCP servers for use across agents. x.com/vercel/status/…
Cursor Router keeps improving from millions of in-product user interactions each week. We intelligently classify and route requests, lowering latency and reducing cost based on the task.
No model dominates every kind of task. Grok 4.5 offers strong value on routine tasks. GPT-5.6 Sol is effective on planning and codebase comprehension. Opus 5 excels for execution-heavy work, and Fable 5 on debugging and visual implementation.
We're open-sourcing Mixture-of-Kittens (MoK), our MoE training megakernel for NVL72s. It fuses all Mixture-of-Experts communication and computation into a single, fully deterministic kernel, and runs up to 2.37x faster than the strongest public baselines.
MoK now powers training across tens of thousands of GPUs at Cursor. In production, it raised end-to-end training throughput by 1.41x over our previous DeepEP-based stack.
Cursor can now read, write, and act across your Google Workspace. New plugins give agents direct access to Gmail, Google Drive, Calendar, Docs, and Sheets.
Install them from the Customize page in Cursor. Learn more: cursor.com/changelog/goog…
Cloud agents are now 20-30% more token efficient, and 80% more efficient on runs with computer use. We've improved how they handle MCPs, skills, and computer use, so you can delegate more ambitious tasks and get back demos while staying within budget. x.com/cursor_ai/stat…
In December, 1 in 10 of our merged PRs came from cloud agents. Today, it’s 56%, as we use cloud agents to complete longer engineering tasks from start to finish. We got here by giving agents their own cloud computers and letting them fix and improve their environments.

Cursor is now on iPad. All the power of Cursor on iPhone, with more room to work with agents.
New to both iPhone and iPad: an inbox to stay organized, and a review experience that covers the full PR, including comments, checks and approvals.
Today we're launching Cursor Start, a new ₹649/month plan for developers in India. Start includes generous access to Grok 4.5 and Composer, so you can plan, build, test, and ship with agents every day.
Cursor Start also includes: - Autonomous cloud agents that ship work while you're away - Cursor for iOS to steer them from your phone - Plugins, MCP servers, hooks, and skills to extend your workflow Learn more: cursor.com/blog/cursor-st…
Kimi K3 is now in Cursor! It scores close to the frontier on CursorBench. It's available on US-based inference thanks to our partners Fireworks, Together, and Baseten. Zero Data Retention is also supported.
Claude Opus 5 is now available in Cursor! It matches Fable 5 on CursorBench (66.7 vs 66.5 at default effort) at half the price. Unlike Fable, it's also compatible with Zero Data Retention.

Introducing Cursor Router, our intelligent model router that selects the right model for the task at hand. Router delivers frontier-quality results at 60% lower cost.
Select Auto mode and whether you’d like to optimize for Intelligence, Balance, or Cost. Cursor Router analyzes each request and routes to the best model for the job: frontier models when the work demands them and price-efficient models when it doesn't.
We've doubled usage limits for all individual and teams plans! These limits apply to Grok, Composer, and any new Cursor models.
We had a team of agents rebuild SQLite from its 835-page manual. It created a replica in Rust which passed 100% of a held-out test suite. Interestingly, cost varied 15x depending on which model mix we used.
Introducing side chats, a new way to ask questions and explore ideas without interrupting your main conversation. Each side chat is a durable agent conversation you can @-mention to bring context back into the main thread.
You can now search agent transcripts to find past agent chats. Cursor builds a local search index that delivers fast search across thousands of conversations.
GPT-5.6 Sol, Terra, and Luna are now available in Cursor. On CursorBench, Sol scores 67.2%.
