Cursor

Overview

Cursor (developed by Anysphere) is one of the largest products in the AI coding track by valuation and scale in 2026: reaching 1 million users + 360,000 paid customers in 16 months, with annualized revenue of approximately $2 billion. In May 2026, SpaceX secured an option to acquire Anysphere for $60 billion (preempting the a16z consortium that was raising $2 billion at a $50 billion valuation), with valuation multiplying 24 times in 16 months. The all-stock acquisition closed on 2026/8/14, making Cursor a wholly owned subsidiary of SpaceX. The Grok 4.7 model launched on 2026/9/21, alongside improved token efficiency for long-running agents.

The product itself is an "AI-native" code editor, deeply modified based on VS Code—Tab completion, Cmd+K inline editing, Composer multi-file refactoring, Agent mode, and terminal execution are all native capabilities, not plugins. The platform has since expanded well beyond the editor: on 2026/8/17 it opened the early beta of Origin, a code hosting service positioned as a GitHub alternative, to all paid plan users; on 2026/9/10 it launched Projects (beta), a coordinator agent that directs thousands of subagents on large development tasks; and on 2026/9/23 it released the Rollouts and Security Reviewer development bots for the software delivery pipeline.

Latest version Composer 2.5 (launched on 2026/05/18): Self-developed model upgrade, base model based on Moonshot's open-source Kimi K2.5 (trillion-parameter MoE, approximately 32 billion activated), with 85% of compute used for post-training + text feedback reinforcement learning + 25x synthetic data. SWE-Bench Multilingual 79.8% (at launch, only 0.7 percentage points behind Opus 4.7); CursorBench v3.1 surpasses Opus 4.7 (63.2% vs 61.6%); price only 1/10 of the contemporary Opus flagship ($0.50/$2.50 per M tokens). This release proactively disclosed the Kimi K2.5 base model source, significantly improving transparency.

2026/7/9 SpaceX×Cursor relationship materialized into a specific product: Both parties jointly trained and released Grok 4.5 (1.5T parameter V9 base model, incorporating trillions of real Cursor developer interaction data), and it has been natively integrated into the Cursor editor, becoming a new cost-effective model option—Token consumption for completing SWE-bench Pro tasks is only 1/4 of Opus 4.8. The model line has continued to advance: Grok 4.7 launched on 2026/9/21. On 2026/7/22 Cursor released Cursor Router, an intelligent model routing system that automatically assigns each coding request to the most suitable model; online A/B testing shows Auto Intelligence mode achieves user satisfaction close to Fable while reducing costs by approximately 60%, and Auto Balance mode surpasses Opus 4.8 in satisfaction with a cost reduction of about 36%. Note: Anthropic released Opus 4.8 on 5/28 and the more cost-effective Sonnet 5 on 6/30. The comparison benchmarks at the time of Composer 2.5's launch are no longer the latest flagships, but the price advantage logic still holds.

Since 2025-08 it moved from "request limit" to "usage-based credit system"; setting Composer 2 as the default in Auto mode helps keep credit consumption down. Cost-efficiency has continued to improve: Cursor Router (2026/7/22) cuts cost by roughly 60% in Auto Intelligence mode and about 36% in Auto Balance mode; the builds feature (2026/8/13) is enabled by default for all environments at no additional cost starting August 17; and on 2026/9/23 Cursor improved its agent harness, cutting user token costs by 7% without lowering agent quality.

Summary

Cursor is currently one of the top 2 AI coding products (the other being Claude Code), with almost no rival in daily coding / multi-file refactoring / rapid iteration scenarios, especially Composer 2 which brings top-tier coding capability price down to one-tenth of the contemporary Opus flagship. Starting 2026/7/9, a new Grok 4.5 option is added (jointly trained by SpaceX×Cursor, with overwhelming Token efficiency), further enriching the model matrix; the model line advanced again with Grok 4.7 on 2026/9/21, and Cursor Router (2026/7/22) automatically routes each request to the most suitable model. The platform has grown from an editor into a full delivery stack: Origin code hosting (2026/8/17), Projects (beta) coordinator agent (2026/9/10), Rollouts and Security Reviewer bots (2026/9/23), Self-Hosted Machines (2026/9/2), and remote control for local agents on iOS (2026/10/6). Selection advice: Choose Cursor for daily coding (can pair with Grok 4.5 for ultimate cost-effectiveness), Claude Code for complex autonomous tasks and deep reasoning, and Copilot for limited budgets.

Version History

• Cloud Agent Canvases and Environments API (2026-10-16): Cloud agents can now build interactive canvases and share finished ones with the team via a link; the Environments API enters beta for programmatically creating and managing cloud environments; environments now support up to 300 repositories and large environments load 5x faster.
• Remote control for local agents on iOS (2026-10-06): Cursor shipped remote control for local agents in its iOS app, letting users view and reply to agents running on their computer. It is on by default for everyone except enterprise organizations, computers on the signed-in account appear automatically, and approving pairing in the desktop app is all that is needed. Agents still run on the local machine, so the computer has to stay on and connected, with a prevent-sleep option in settings and an admin toggle in organization settings
• Cursor launches Rollouts and Security Reviewer development bots (2026-09-23): Cursor released two bots for the software delivery pipeline: Rollouts moves code to production faster, while Security Reviewer handles pre-release security review, aiming to let teams ship quickly without giving up reliability.
• Ships the Rollouts and Security Reviewer bots (2026-09-23): Cursor released two software development bots, Rollouts and Security Reviewer, the first watching every deployment and the second handling security review, to help teams get secure and dependable code into production faster. Cursor also improved its agent harness, cutting user token costs by 7% without lowering agent quality.
• Cursor acquired by SpaceX; launches Grok 4.7 model; improves token efficiency for long-running agents. (2026-09-21): Cursor acquired by SpaceX; Grok 4.7 model launched; improved token efficiency for long-running agents.
• Cursor launches Projects (beta), a coordinator agent directing thousands of subagents on large development tasks (2026-09-10): Cursor launched Projects in beta, rolling out to all users. You chat with a project's coordinator agent, which writes no code itself but delegates tasks to thousands of subagents running in parallel, so it is never blocked and always responsive. A project runs on its own cloud computer by default and keeps working when you close your laptop; when something needs local testing, the coordinator spins up a local agent. Each project maintains shared context synced across cloud and local machines, so research findings, codebase knowledge and user preferences recorded by one agent are reused by future agents. It also supports subscriptions: watching a Slack channel, running on a schedule, or following all your PRs to fix CI automatically. Internally, Cursor users who primarily use Projects merge about six times as many PRs, and new users merge 30% more.
• Cursor launches Self-Hosted Machines, letting cloud agents run on a company's own machines (2026-09-02): Cursor releases Self-Hosted Machines, migrating the tool execution of cloud agents to machines within the enterprise's own network. The agent loop, reasoning, and planning remain on Cursor's cloud, connected via outbound HTTPS from workers, and Cursor does not proactively connect into the enterprise network.
• Cursor responds to OpenAI's plan to block its model access (2026-08-29): We regret to see that OpenAI has issued a statement announcing plans to block Cursor users from accessing OpenAI models within three months. OpenAI models carry approximately 5% of Cursor's user traffic, and we are communicating with the OpenAI team to resolve this matter. Cursor has been one of OpenAI's earliest users, and over the years we have worked closely with their team, consistently trusting their platform as neutral infrastructure for our business.
• OpenAI decides to cut off model access to Cursor over compliance risks following the SpaceX acquisition (2026-08-28): OpenAI has notified SpaceX that it will terminate the contract to provide OpenAI models to Cursor, with a proposed shutdown date of November 12, 2026, and has given the longest notice period allowed under the contract. OpenAI stated that this move stems from its inability to be confident that SpaceX will comply with the terms of service, citing precedents of Musk's companies previously violating contracts and xAI violating OpenAI's service terms. OpenAI expressed that it will make every effort to support affected developers during the transition.
• Cloud Agents can now create projects from scratch without connecting GitHub or other third-party repositories, and save them to Cursor Origin (2026-08-27): Cloud Agents now supports creating projects from scratch without connecting to third-party repositories such as GitHub, and allows saving them to the Cursor Origin repository.
• Cursor posts a Changelog update enhancing Cloud Agents and Cursor Harness: cloud agents can respond automatically (2026-08-19): Cursor released a Changelog update, enhancing Cloud Agents and Cursor Harness capabilities: cloud agents can automatically respond to events and pick up work, persistently hold goals until completion, and support long-running sessions; a new Subscriptions feature is added, enabling monitoring of PRs, Slack threads, or running scheduled tasks.
• Cursor launches Origin, a code hosting service positioned as a GitHub alternative (2026-08-17): Starting today, Cursor is opening the early beta of Origin code hosting to all paid plan users, offering repositories, pull requests, code browsing, and GitHub sync features. Users can create repositories prefixed with cursor.com/codebase/ or sync GitHub repositories to Origin, with bidirectional sync of comments and reviews. Integrations with Vercel, Depot, and Buildkite are now available, with agent features coming soon.
• Cursor launches builds: cloud agents now start up to 3x faster (2026-08-13): Cursor launches the builds feature, which continuously prepares ready-to-use copies of development environments in the background, allowing cloud agents to start without building from scratch and improving response speed by up to 3 times. Internal environments start 10 times faster, and the first token is generated 3 times faster; agents always start from the most recent successful build, so dependency updates or installation script errors won't affect runtime. Starting August 17, builds will be enabled by default for all environments at no additional cost.
• Cursor releases Cursor Router, an intelligent model routing system (2026-07-22): Cursor has launched Cursor Router, which automatically assigns each coding request to the most suitable model. Online A/B testing shows that the Auto Intelligence mode achieves user satisfaction close to Fable while reducing costs by approximately 60%; the Auto Balance mode surpasses Opus 4.8 in satisfaction, with a cost reduction of about 36%.
• Cursor Router Intelligent Model Routing (2026-07-22): Automatically assigns coding requests to the most suitable model; Auto Intelligence reduces cost by ~60%, Auto Balance satisfaction exceeds Opus 4.8 with 36% cost reduction
