Cursor Composer 2.5 vs Claude Code (2026)

The short version

Cursor's Composer 2.5 is still the cheaper, faster choice for everyday in-IDE editing, and Claude Code remains the stronger pick for full-codebase reasoning. What changed since March is how much smaller that price gap now is, since Claude Code defaults to a mid-tier model rather than its costliest one, and Composer's fast tier got pricier too.

Cursor shipped Composer 2.5 on May 18, 2026, and Anthropic has swapped Claude Code's default model twice since then, first to Sonnet 5 in June and then to Opus 5 in July.

That is two version changes to the exact tools this comparison was built around in March. Composer 2 beat Opus 4.6 on a couple of benchmarks back then, and that win no longer describes anything real: the older model is three releases behind, and the newer agent does not even default to a flagship model anymore.

The real question this quarter is not which March-era benchmark won. It is whether the cheaper tool still buys enough capability, and whether the pricier one's bigger context window is worth the extra seat cost.

The Verdict, Up Front

Composer 2.5 remains the pick for high-volume, in-IDE editing: multi-file refactors, boilerplate, and test generation, priced at $0.50 per million input tokens and $2.50 per million output on its standard tier, according to the vendor's own pricing page.

Claude Code, now on a mid-tier model by default with a pricier option for harder problems, is the pick when a task needs to reason across an entire codebase rather than edit inside one file at a time. That trade held true in March. What changed is the size of the price gap between the two choices, and it shrank.

What Actually Changed Since March

Anthropic made Sonnet 5 the coding agent's new default model on June 30, 2026, with a native 1-million-token context window, according to the tool's own changelog. Opus 5 followed on July 24, priced the same as its predecessor: $5 per million input tokens and $25 per million output.

Composer replaced its own prior version on May 18. It runs on the same base checkpoint as before but was retrained with 25 times more synthetic coding tasks, with most of the training budget spent on post-training and reinforcement learning, according to the release notes.

Neither company's naming makes any of this obvious from outside. A reader searching for this comparison today mostly finds older write-ups still benchmarking retired models on both sides.

The Price Gap Is Narrower Than the Headline

On paper, Composer is still the cheap option: $0.50 per million input tokens against $5 for Opus, a tenfold gap on the standard tier. But its fast variant, the one most users actually run, now costs $3.00 per million input tokens and $15.00 per million output, up from $1.50 and $7.50 on the prior version. That is a doubled price on the tier most developers use day to day.

Sonnet, not the flagship, is the model a Claude Code session runs on by default, at introductory pricing of $2 per million input tokens and $10 per million output through August 31, 2026, rising to $3 and $15 after that date. Compare the fast tier against the model each tool actually defaults to, and the tenfold gap the original comparison reported closes to somewhere between two and four times.

Subscription pricing tells a smaller version of the same story. Cursor's Pro plan costs $20 a month, Pro+ is $60, and Ultra is $200. Claude Code's Pro plan is $17 a month billed annually, or $20 billed monthly, and includes the coding agent outright, while Max plans start at $100 for five times the usage. Both companies' cheapest paid tiers land at the same $20 when billed monthly.

What the Benchmarks Show, and What They Don't

Neither vendor has published a benchmark comparing the two current models directly. The most recent independent number comes from Artificial Analysis's Coding Agent Index, measured before Opus 5 shipped: Composer 2.5 scored 62, third place, behind Claude Opus 4.7 at maximum reasoning effort, which scored 66 at $4.10 per task. Composer 2.5 finished the same tasks for $0.07 on standard and $0.44 on fast, a cost gap of roughly 10 to 60 times against the model ranked above it, per the firm's own write-up.

Anthropic's comparison point for Opus 5 leans on a rival's benchmark rather than its own. On CursorBench 3.2 at maximum effort, Opus 5 scores within half a percentage point of Fable 5's best result, its own top model, at half the cost per task, according to the July 24 launch announcement.

Neither company has run the two current models head to head on a shared benchmark, so the honest answer is that no independently verified ranking between them currently exists. What is measurable: Opus 5 leads the same firm's broader Intelligence Index and scored 1,720 Elo on its agentic knowledge-work benchmark, 146 points ahead of Fable 5's 1,574.

Where Composer 2.5 Wins

Composer 2.5 is still the faster, cheaper choice for the bulk of daily editing work: multi-file refactors under a few hundred lines, boilerplate generation, and test writing inside Cursor's Agent Mode. A four-person startup team running high-volume agent sessions all day spends a fraction of what the same volume costs against a rival's API, even after the recent price increase.

It also inherited its predecessor's compaction-in-the-loop training, which compresses its own working context during long sequences rather than depending on a very large context window, so it holds up better on long single-file edits than a model built to keep everything in memory at once.

Where Claude Code Wins

Its edge is reasoning across a codebase that Composer was never trained to hold in view at once. Both current Claude models ship with a native 1-million-token context window by default, up from the 200,000-token window Claude Code used in March.

That matters for architectural review, cross-repo refactors, and Dynamic Workflows, a feature added in May 2026 that fans a single task out across up to 100 parallel subagents. One developer reported using it to complete an eleven-day migration spanning roughly 750,000 lines of code. Composer has no equivalent multi-agent mode.

Claude Code also connects to Figma's MCP server for two-way design-to-code work, capturing a running interface and sending it back as editable layers. The design tool's own community forum has open reports of this specific integration failing mid-session with a "couldn't send" error, so treat that workflow as promising rather than dependable today.

The Case Against This Verdict

The strongest objection to everything above is that it will be wrong again within weeks. Anthropic changed its coding agent's default model twice in five weeks this summer, and Cursor has already shipped one update since March. Comparing tools by version number means comparing a moving target to another moving target, and a reader landing on this page in October will find some of these prices out of date.

That is fair, and it is why the more durable comparison is architectural rather than numerical. One side bets on a compact, cheap, IDE-bound model with aggressive context compression. The other bets on very large context windows and parallel agents at a materially higher price. Those two bets do not change every time a version number ticks up, even when the prices attached to them do.

What Switching Actually Costs

Moving from one tool to the other is not free, and neither vendor advertises the friction. Agent Mode workflows, keyboard shortcuts, and background-indexing habits do not carry over to a terminal tool. A team switching loses in-editor diffs and gains a CLI learning curve, plus the work of wiring up connections to outside services that were already built in before. Moving the other way means giving up cross-file reasoning and parallel agents for a faster, cheaper single-file loop.

Windsurf, the other IDE-native option this comparison used to list as the cheap alternative, no longer exists under that name. Its parent company folded it into a rebranded desktop product on June 2, 2026, months after acquiring it, and retired its original in-house agent in favor of one built from scratch. A team that picked this tool specifically for its brand five months ago is, whether it noticed or not, now running a different product.

For a team that only cares about raw token cost and does not need either tool's coding-specific tuning, DeepSeek undercuts both by a wide margin: its cheapest current model prices output at $0.28 per million tokens, according to the company's own pricing documentation. Neither rival's editor or terminal integration runs on top of it without separate tooling, and it was not built for either kind of workflow.

What Would Change This Answer

Anthropic has now changed its coding agent's default model three times since February, and Cursor has changed its own pricing twice since March. Whichever company skips a release cycle first is the one whose numbers in this comparison stay true the longest.

Frequently asked questions

Is Cursor Composer 2.5 still cheaper than Claude Code?

On raw per-token pricing, yes: Composer 2.5's Standard tier costs $0.50 per million input tokens against $5 for Claude Opus 5. But Sonnet 5, not Opus 5, is Claude Code's default model, and it prices input at $2 per million tokens through August 31, 2026. Measured against the model most Claude Code sessions actually run, the price gap is closer to 2x to 4x than the 10x figure many older comparisons still repeat.

What model does Claude Code use in 2026?

Claude Code has defaulted to Sonnet 5 since June 30, 2026, with a native 1-million-token context window. Opus 5, released July 24, 2026, is available as the flagship option for harder reasoning tasks at $5 per million input tokens and $25 per million output tokens.

Is Windsurf still a separate product from Devin?

No. Cognition AI rebranded Windsurf to Devin Desktop on June 2, 2026, following its acquisition of the company in December 2025. Windsurf's original agent, Cascade, was retired on July 1, 2026, and replaced by Devin Local.

Does Composer 2.5 or Claude Code score higher on coding benchmarks?

On Artificial Analysis's Coding Agent Index, the most recent independent measurement, Composer 2.5 scored 62 against Claude Opus 4.7's 66, both recorded before Opus 5 shipped. Neither Anthropic nor Cursor has published a head-to-head benchmark of Composer 2.5 against Opus 5 or Sonnet 5, so no independently verified current ranking exists between them.

Can I use Cursor and Claude Code together?

Yes, and it remains the practical answer for most teams: Composer 2.5 for high-volume in-IDE editing at a fraction of the cost, Claude Code for cross-file reasoning and Dynamic Workflows tasks that span many files at once. Both tools also connect to Figma's MCP server for design-to-code work, though Claude Code's implementation has open bug reports on Figma's community forum as of this writing.
