TLDR:
- Cursor launched Composer 2 on March 18, 2026. A code-only AI model built to rival OpenAI and Anthropic at a fraction of the cost
- It outperforms Claude Opus 4.6 on CursorBench and starts at just $0.50 per million input tokens
- With over 1M daily active users and $2B+ in annual revenue. Cursor is no longer just a code editor. It’s an AI company
I’ve been watching the AI coding space closely for the past two years. Every few months, something comes along that reshuffles the deck. Composer 2 is one of those moments.
Cursor dropped it on March 18, 2026 and the developer community immediately took notice not because of the hype. But because of two very specific things: the benchmark numbers and the price. When a model beats Claude Opus 4.6 and costs $0.50 per million input tokens, people pay attention.
What Is Composer 2?
Composer 2 is Cursor’s third in-house AI model, built exclusively for code. It doesn’t write blog posts, summarize meetings or answer general knowledge questions. It writes, debugs and refactors code and it does it really well.
This isn’t a bolt-on feature or a rebranded API call to OpenAI. Cursor trained this model from scratch, including a continued pretraining run that gave it a stronger foundation before reinforcement learning was applied. The result is a model purpose-built for long-horizon agentic coding. Tasks that require hundreds of back-to-back decisions across an entire codebase.
For developers who’ve tried AI agents that fall apart after five or six steps, that matters a lot.
What the Benchmarks Actually Show
Numbers on paper mean nothing without context. So here’s what’s worth paying attention to.
On Cursor’s internal CursorBench, Composer 2 scores 61.3. Composer 1.5 — the previous version scored 44.2. That’s not an incremental update. That’s a significant jump in real coding capability.
On the same benchmark, Anthropic’s Claude Opus 4.6 scores 58.2. Composer 2 beats it. OpenAI’s GPT-5.4 Thinking edges ahead at 63.9. But the margin is close, and the price gap between the two is massive.
On Terminal-Bench 2.0 and SWE-bench Multilingual. Two third-party benchmarks that the broader developer community actually trusts. Composer 2 also shows strong improvements over its predecessor.
The Pricing Is Where Things Get Interesting
Here’s a side-by-side look at what you’re paying per model:
| Model | Input (per 1M tokens) | Output (per 1M tokens) |
|---|---|---|
| Composer 2 Standard | $0.50 | $2.50 |
| Composer 2 Fast | $1.50 | $7.50 |
| Claude Opus 4.6 | $5.00 | $25.00 |
| GPT-5.4 | $2.50 | $15.00 |
The Fast variant is the default option inside Cursor. Cursor says it delivers the same output quality as Standard — just at higher speed. Even at the Fast tier pricing, you’re spending 3x less than Claude Opus 4.6 on output tokens alone.
For startups or dev teams running thousands of agentic calls per day, that’s not a small line item.
Why Cursor Needed to Build This
This is the part that often gets glossed over in coverage of Composer 2.
For most of Cursor’s history, the product ran on top of API access from OpenAI and Anthropic. Those same companies are now building their own developer tools. Claude Code, Codex and more and competing head-to-head with Cursor for the same users.
That’s a precarious position. You’re paying your competitors to power your product and those competitors can raise prices, restrict access or simply build a better version of what you’re selling.
Composer 2 changes that dynamic. Cursor now controls its own model. Its own pricing and its own roadmap. That’s a strategic move as much as a technical one.
The Market Context
Cursor isn’t operating in a quiet corner of the tech world. This is one of the most competitive segments in software right now.
OpenAI spent roughly $3 billion to acquire Windsurf. Anthropic is pushing Claude Code aggressively. Google previewed Antigravity, a free AI-native IDE. Microsoft’s GitHub Copilot is still deeply embedded across enterprise teams worldwide.
Against that backdrop, Cursor’s numbers are striking. Over one million daily active users. More than seven million monthly active users. Adoption across more than half of the Fortune 500. Stripe alone has rolled it out to 3,000+ developers.
Revenue hit $2 billion annualized in February 2026 — doubling in three months. Bloomberg reported in mid-March that the company is in preliminary talks for a new funding round at approximately $50 billion. That’s up from its last valuation of $29.3 billion just months earlier.
Should You Actually Use It?
If you’re a developer already inside the Cursor ecosystem. Composer 2 is available now no waitlist, no special access required. It also runs inside the new Glass interface. Which is in early alpha but already drawing positive early feedback from power users.
If you’re evaluating AI coding tools for a team. The pricing model alone justifies running a test. The benchmark performance puts it legitimately in the conversation alongside much more expensive options.
Cursor has spent two years building trust with developers through product quality. Composer 2 is the company’s clearest statement yet that it’s playing the long game and it’s not planning to stay dependent on anyone else to get there.
