Key Points

The post announces that “Opus 4.7” has just been launched and is now available on Cursor for users building serious applications.
It argues that using Opus for complex logic can improve code quality and outcomes compared with standard models.
The author recommends using the upgrade to prioritize core architecture improvements and technical debt cleanup rather than simply adding features.
It also encourages teams to tackle previously “too complex” builds, framing the change as a rare case where better output can reduce overall cost.
The discussion invites readers to share what other LLMs they use to build or improve their apps.

If you're building a SaaS or any serious app, this is probably the cheapest way to level up your code quality fast.

I’ve seen a huge difference using Opus for complex logic vs standard models.

Use this time smartly:

Fix your core architecture (don’t just add features)

Clean up technical debt

Build things you were avoiding because “too complex”

This is one of those rare moments where better output costs less.

Curious — what other LLM do yoi use to build or improve your apps?
