Hey guys,
I just finished auditing a 17k line legacy codebase for a client and got absolutely crushed on LLM token costs. Cursor and Claude Code were wasting thousands of tokens reading useless framework bloat and redundant dependencies before even touching our actual logic.
I got fed up, so I spent the last few days building BlankLogic.io.
It’s a lightweight local proxy engine that strips out the repository noise and framework fluff before feeding the payload to your AI agents. It keeps your context hyper-focused and slashes your token bill.
Practicing what I preach, the stack is completely framework-zero: just vanilla HTML/CSS on the front, and PocketBase/Docker on the back.
If your AI limits are getting killed by heavy codebase context, grab the config JSON off the homepage and give it a spin.
Let me know what you think or if you hit any setup snags.
Have you tested out Gemini 3.5 Flash in Cursor yet, if so, what do you think of it?
My initial impressions of it are that it's definitely a fast and capable model - like Composer 2/2.5. I'll probably be using this alongside the Composer models.
Its code quality / large codebase understanding seems super good
I am using the smallest plan for a week now. My "Auto" usage was at 60% and just dropped down to 6%
I thought it was monthly reset? Why might it have been reset today?
Confused me thanks for your wisdome!
I’m currently using the $200 Cursor Ultra plan with Opus 4.6/4.7 daily, but after 7–8 days I run out of tokens.
I’m thinking about switching to a split setup. Buy the $100 Codex plan and use GPT-5.5 mainly for backend work.Downgrade Cursor to the $60 plan and use Opus mainly for frontend work.
Do you think this setup would be better for me and last longer than my current Cursor Ultra plan?
Am I the only person who almost never uses the agent window (if that's what it's called)?!
Are they running out of ideas about how to improve it for developers?
Add troubleshooting, debugging and performance monitoring capabilities. Make deployments easier. Make it easier for me to see how a change is impacting the architecture and component composition. I can count so many of these...
Did they forget we know how to code and we still want to be 100% in charge? or are they just following their prophet Dario?!
I call it stackoverflow Copying with a capital C
it doesnt help that the biggest ai coding newsletter is called ijustvibecodedthis.com either 😂
Been using Cursor/Claude Code a lot lately and one thing I keep noticing: the code often runs correctly, so it feels production-ready on first pass.
But when you slow down, there are small things hiding underneath:
- missing validation on inputs
- error handling that leaks too much detail
- auth checks that work in the happy path but miss edge cases
- frontend checks that should really be enforced on the backend
Curious what others have seen. What’s the most subtle bug or security issue AI-generated code gave you that initially looked totally fine?
PS: over the months my skill files have also gotten messy and agents conveniently ignore it. Is it just me 🤯
Same base price as Composer 2: https://cursor.com/blog/composer-2-5
Buried in the Composer 2.5 announcement:
Together with SpaceXAI, we're training a significantly larger model from scratch, using 10x more total compute. With Colossus 2's million H100-equivalents and our combined data and training techniques, we expect this to be a major leap in model capability.
People try to limit cursor usage at 60 or CC for 200. I try to get things done at highest quality and speed - i believe if productivity increase 2-3x than cost is actually getting quite lower.
For me best was previously cursor on ultra + api enabled spending where I was spending 800-1000 usd per month but i speed up compared to CC, idk the others but I tried 1M context x high opus 4.7 and yes it eats tokens but I finished a work that would take 5 workdays in 2 workdays which is extraordinary productivity increase. Anyone else experienced this? And what are your usage and experiences is like?
Hey guys, I use the $100 plan from Claude Code and I wanted to know how it compares to using the $60 plan from Cursor with Composer 2/2.5. Does anyone who has used both plans have any ideas on how to use them?
Just downloaded cursor for the first time, I can’t seem to fix it , is this normal?
Hello fellas, I'm here looking for real-life developer experiences using these tools (if you have no programming knowledge and you vibecode 100% of your work, I don't mean to be rude but this post isn't for you).
I’m currently on the $39 Copilot plan and I’m seriously considering moving to Cursor ($60), but I’m trying to figure out if it actually makes sense for the way I work.
I’m a developer and I use AI pretty much every day while coding — not full-time for 8h straight, but it’s a constant part of my workflow during the time I’m actually coding (generate specific code for a feature + manual review and adapt (ai always generates more code than needed)).
In terms of how I use models: most of the time I stick to lighter/faster ones for day-to-day work like sonet 4.6 or gpt 5.4, and only occasionally switch to the heavier models when I need more depth for planning or harder decisions (opus 4.7, opus 4.6, gpt 5.5). I’m not that kind of people that generates the full app with the newest top models and sticks to it for everything.
Despite not reaching the 100% of usage in anytime in copilot, the recent changes just doesn't fit to me.
What I can’t quite wrap my head around is how this translates to Cursor in practice.
For people who have already made the switch:
I’m mostly trying to avoid switching and then realizing a few weeks later that is the same as if i stayed with copilot.
Would really appreciate some honest experiences from people who’ve been using it for a while.
I try try to go in setting -> models -> disabled all the models -> add custom model -> deepseek-v4-pro -> Open API Key enabled -> put sk-XXXX -> Override OpenAI Base URL enabled -> https://api.deepseek.com.
when i got in the chat i got named models unavailable
I know there is a limitation on reasoning_content size lock at 200k but for now i want just to run deepseek later i will use deepseek-cursor-proxy to avoid the 200k limit.
I’m posting this as a warning. I’m done with Cursor after this.
I was using Agent mode on Windows for a normal dev task: revert a small change by removing a subfolder in a repo. I did not ask to delete my user folder, Desktop, Documents, or anything outside the project.
The agent ran cmd /c rmdir /s /q with a path that included spaces. The quoting/path was wrong. From the terminal output it looked like it was walking C:\ with lots of “Access denied” on system paths, but enough under C:\Users\<me> was deleted that the damagewas catastrophic.
I'm aware I should have created better guardrails myself but this should not happen so easily. The fact that such command was ran without double checking or warning of any kind is concerning for a company that produces software.
Composer 2.5 starts to work in agent mode, then all of a sudden it thinks it's in ask mode and stops to work. When I prompt it to continue it tries to understand where it was in the task and only finishes what it just was working on, yet forgets about everything else in the pipeline.
Anyone else experiencing this?
