Cursor Composer 2.5: What Changed and Who Should Switch

Composer 2.5 is now the default Composer model in Cursor. This page summarizes only what Cursor states on its official changelog—no third-party benchmark claims.

What Changed

According to Cursor's official Composer 2.5 changelog (May 18, 2026), Composer 2.5 is available in the editor and is positioned as a substantial improvement over Composer 2 for intelligence and day-to-day collaboration.

Cursor highlights three practical themes developers care about:

• Longer-running work — better sustained performance on multi-step coding tasks.
• Complex instructions — more reliable following of detailed prompts.
• Collaboration quality — Cursor describes the model as more pleasant to work with, not only stronger on paper.

The changelog also notes that Composer 2.5 is the new default in the model picker (Composer 2 remains available if you prefer it).

Who Should Switch

Consider moving to Composer 2.5 if you already rely on Cursor's Composer for multi-file edits, refactors, or agent-style tasks that span many tool calls. The official positioning targets teams that felt Composer 2 was capable but inconsistent on long horizons or nuanced instructions.

You may want to stay on Composer 2 temporarily if you have a pinned workflow, custom evals, or billing guardrails tied to the older model name—switch only after confirming the picker and any API identifiers in your environment.

Usage Pricing (Official)

Composer 2.5 usage pricing on Cursor's changelog (product-model usage, not the same as public LLM API list prices on our LLM API pricing compare):

• Standard: $0.50 per million input tokens, $2.50 per million output tokens.
• Fast (default): $3.00 per million input tokens, $15.00 per million output tokens.

Promotions such as limited-time usage boosts can change; always confirm on the changelog before budgeting.

vs Composer 2

Cursor frames Composer 2.5 as the successor default—not a separate product line. If you used Composer 2 for multi-file agent work, you should expect the same Composer panel workflow with an updated underlying model. The meaningful decision is whether the changelog's emphasis on long tasks and instruction following matches your workload, not whether the UI changes.

We do not reproduce third-party benchmark tables here; verify any performance claims on official Cursor materials only.

FAQ

Where is the primary source?

The authoritative page is cursor.com/changelog/composer-2-5.

Does this replace my ChatGPT or Claude models inside Cursor?

No. Composer 2.5 is Cursor's Composer-family model. You can still pick other frontier models in Cursor when the task calls for them.

Is Composer 2.5 the same as API pricing on OpenAI or Anthropic sites?

No. Those are separate vendor API list prices. Composer usage billing follows Cursor's product-model rates above.
