# Cursor Composer

214 Hacker News commenters recommended Cursor Composer and 79 criticized it, November 2025 to November 2026. It was recommended in 12 of 13 months; owners who said how long report a median of 0.1 years (11 owners). It meets the Hacker Approved badge rule.

**Verdict:** Cursor's in-house coding model is recommended for being very fast and cheap with solid results on planned or simple tasks, though critics say it trails frontier models on complex work.

## Why people recommend it

- Extremely fast responses (12 comments): "It enables a totally different way of AI coding - instead of giving the LLM a long prompt and waiting minutes for it to finish, you give it a shorter prompt to just write one small thing and it finishes in seconds." ([source](https://news.ycombinator.com/item?id=45884991)) "ended up progressing with the composer code because it was easier to progress with improvements due to its faster response time" ([source](https://news.ycombinator.com/item?id=48760031)) "Composer is clearly dumber than the rest but then I only ask it dumb questions and it answers them really quickly." ([source](https://news.ycombinator.com/item?id=47857332))
- Cheap and token efficient (7 comments): "it's apparently quite token efficient, so why would it be impossible for a Chinese lab to achieve something similar?" ([source](https://news.ycombinator.com/item?id=48986390)) "Incredibly token efficient, fast, and gets the same quality as if you worked the whole thing with Fable/Opus/GPT" ([source](https://news.ycombinator.com/item?id=48812372)) "When you normalise for time and money, Composer 2.5 is way, way, way, way better than anything else out there." ([source](https://news.ycombinator.com/item?id=48760071))
- Quality close to frontier models (5 comments): "Composer 2.5 worked just as well for me as opus 4.6, and was faster and actually worked better for quick bugfixes" ([source](https://news.ycombinator.com/item?id=48557724)) "Incredibly token efficient, fast, and gets the same quality as if you worked the whole thing with Fable/Opus/GPT" ([source](https://news.ycombinator.com/item?id=48812372)) "It's a model that runs inexpensively in their coding workflow that is creating results similar to opus or gpt." ([source](https://news.ycombinator.com/item?id=48186666))
- Follows plans well (4 comments): "composer 1 is great at following plan instructions so after some careful time providing the right context and building a plan, it basically never messes up the implementation" ([source](https://news.ycombinator.com/item?id=46329449)) "I actually really like Composer 2. For my use case, between the planning tool, and getting it to ask a lot of clarifying questions, I regularly get very good results." ([source](https://news.ycombinator.com/item?id=47856360)) "Composer did a competent but not amazing job with a good plan. What I really liked though is it was fast" ([source](https://news.ycombinator.com/item?id=48764278))

## What people warn about

- Noticeably weaker than frontier models (5 comments): "which was decent but still a step back from GPT 5.5 and Opus 4.8. Though it's really good at UI." ([source](https://news.ycombinator.com/item?id=48557767)) "they set themselves up for flack when they use whatever these evals are" ([source](https://news.ycombinator.com/item?id=48183081)) "Just like with Composer 2, it's fast, but quality is nowhere near what Cursor claims with their benchmarks." ([source](https://news.ycombinator.com/item?id=48193131))
- Struggles with complex multi-file changes (3 comments): "it is surprisingly lacking in the actual coding department once you go for edits that need changes in multiple files" ([source](https://news.ycombinator.com/item?id=47860847)) "not tuned to be that agentic, so it's better for one-shot code changes than long-running tasks" ([source](https://news.ycombinator.com/item?id=45969099)) "just lightning fast compared to the others...but sometimes don't find the solution if it's too complicated" ([source](https://news.ycombinator.com/item?id=46849399))
- Benchmark claims seem overstated (3 comments): "they set themselves up for flack when they use whatever these evals are" ([source](https://news.ycombinator.com/item?id=48183081)) "Just like with Composer 2, it's fast, but quality is nowhere near what Cursor claims with their benchmarks." ([source](https://news.ycombinator.com/item?id=48193131)) "This blog post doesn't really give any reason to use it besides "it's better on Cursor's internal benchmark"" ([source](https://news.ycombinator.com/item?id=46951912))
- Trust concerns over Kimi base, data (3 comments): "That doesn't appear to be the case here (Kimi's license requires publicly acknowledging Kimi is used for anyone operating at Cursor's scale)." ([source](https://news.ycombinator.com/item?id=47452668)) "Seriously, this seems like cool work and enjoyed the post. But my basic trust in them has completely tanked." ([source](https://news.ycombinator.com/item?id=47551145)) "Seems like a promising and useful model but its probably scary how much customer data they fed into it" ([source](https://news.ycombinator.com/item?id=48190928))
