Does FinchStory now support GPT6 Luna and Sol?

The most important change in this release is support for GPT6 Luna and GPT6 Sol. For users working with OpenAI / Codex inside FinchStory, that means the new models can be selected directly without manually maintaining a separate underlying environment.

The short answer

Yes. FinchStory 1.0.90 adds support for GPT6 Luna and GPT6 Sol, together with an updated managed Codex environment so the new models work within FinchStory's existing roles and workflows.

GPT6 Luna and Sol are now available directly in FinchStory

The new model support is integrated into FinchStory rather than requiring a separate setup. Existing roles, accounts, and workflows can continue to be used while gaining access to the new model choices.

New models should not require users to maintain the underlying environment

To support GPT6 Luna and Sol properly, FinchStory also updates its managed Codex CLI. FinchStory handles that environment itself, so users do not need to install or maintain the required version manually.

The upgraded environment is protected from accidental rollback

Alongside the upgrade, FinchStory adds an anti-rollback check to reduce the risk that a later installation or environment change falls back to an older managed Codex version and disrupts the new model support.
