## What happened

GPT-6 Astra is rolling out in GitHub Copilot, with a focus on long-running coding and agent tasks.

## Why it matters

A model change can alter how your agent plans, validates and finishes work.

## For builders

GitHub reports stronger long-horizon performance in its internal tests. Treat that as a vendor claim until it survives your own repository.

## Try this

Compare one real bug fix against your current model. Measure passing tests, review effort and total cost.
