Cursor and Claude Opus 4.5 is a game changer

The combination of the two delivers on the promise: fast and clever editing of multiple files in a codebase, with minimal human intervention.

No other model I tried in Cursor comes even close.

Question: did anyone tried Claude Codex: as good as Cursor?

Its even better when using claude code

Try Claude Code, especially with plugins and max plans.

All these AI coding tools make me feel like I have superpowers. It’s addictive.

If I had problems finding time and the mental power or motivation to work on projects a few years ago—projects I deemed too large a commitment of time and effort—today with Claude and Cursor I almost have too much time and bandwidth to take on new projects.

When I step back and realize this is the world we’re living in as programmers, I can barely believe it. I want to shout and laugh from joy.

It’s been months since I’ve manually written more than a few lines of syntax, and I can’t imagine ever going back.

If AI coding tools disappeared from the world today, tomorrow I would stop being a programmer—something I’ve done for over 20 years.

That thought makes me excited and scared

I haven’t written any single line of code but i have been able to plan and come up with new ideas faster

I’m more of a product manager than a coder due to these new AI coding tools

>> Claude Codex

Do you mean codex or Claude code standalone without cursor? Codex is OpenAI’s coding tool competing with Claude.

Based on my limited experimentation Claude code is better. I haven’t used any of these coding agents with an ide only from the cli.

What do you get with claude code that isn't already in cursor? I've only used it in cursor

Claude Code is amazing (I assume that is what you mean by Codex) it integrates into your terminal. The biggest advantage over Cursor is the use of Agents to automate your workflow. an Example is you can have a FileNaming Agent that you give a list of instructions to for whenever a new file is created so it is named a certain way, or a Comment Agent with instructions of whenever a comment is created in your code it puts certain information in. Maybe you can do this all in Cursor too but I dont know how. Also you dont need to pay for the API as you can just use your account to log into Claude Code.

Claude Code, thank you!

I hesitate trying Claude Code, there is a bit of fatigue installing new tools :-)

By the way: ChatGPT 5.1 Codex Max pro, which was rubbish when used directly inside Cursor, is actually very good once I access it via the OpenAI Codex extension installed within Cursor!

Mysteries of toolchains...

Anyway, that proved so useful when I maxed out my Claude credits.
