New Update: GPT-5.4 is now in Shipper!

Hey guys!

Shipper now runs on GPT-5.4 for certain tasks.

The newest OpenAI model just shipped yesterday, and we’ve already started rolling it out inside Shipper.

For tasks that require deeper reasoning, complex coding, and longer planning, Shipper can now tap into GPT-5.4’s better context and improved agent workflows.

This means:

better architecture planning

cleaner code generation

stronger multi-step builds

fewer retries when apps get complex

It’s noticeably better at long workflows and reasoning across big projects.

Most people won’t see the model switch.

They’ll just notice Shipper getting things right more often.
