AI Executive Synthesis
Achieving seamless, non-destructive integration of custom AI models into an existing desktop application's model picker, while preserving all user-specific data (profiles, chats, projects).
This issue exposes critical integration fragility within the `codex-shim` solution. Despite the shim indicating a loaded state, its core function—exposing custom models—fails, and, more critically, it causes data loss by making existing chats and projects disappear. The user's extensive pre-installation cleanup process underscores the inherent instability and potential for state conflicts. This highlights a significant developer pain point: the inability to reliably extend proprietary desktop applications with custom AI models without compromising existing user data or requiring complex, error-prone setup. For B2B SaaS, this level of integration friction and data integrity risk is unacceptable, hindering adoption of BYOK model strategies and demanding more robust, isolated, and non-destructive integration architectures.
