# Sonnet 5.5 in the model picker

By Steven Van · 2026-09-28

Base44 swaps Sonnet 5 for Sonnet 5.5 in the AI chat and agent editor at the same credit rate, and moves saved picks across automatically.

Sonnet 5.5 is now the Sonnet option in both the AI chat and the agent editor in [Base44](<https://creatorstoolbox.com/tools/base44>), at the same credit rate as before. Anyone who had Sonnet 5 saved gets moved to the new model automatically, with no change needed in the picker. The [changelog entry](<https://docs.base44.com/changelog/product#september-28-2026>) points to the "Choosing your model" docs for more.
