## Summary

OpenAI’s ChatGPT desktop app now lets users import chats, settings, and projects from **Claude Code** via a new feature, but with key restrictions. The migration supports up to **50 chats from the last 30 days** and converts files like instruction files (`AGENTS.md`) and settings (`config.toml`), though some elements—such as **slash commands**—merge into different mechanisms (e.g., *Skills*). Authentication, environment variables, and permissions require manual verification after import, as the tool does not guarantee full functionality or real-time sync for migrated items.

Teams relying on long-term project memories or confidential data should audit the transfer carefully. The process involves **seven steps**, but the bulk of effort lies in post-migration checks, including validating **instruction files, project folders, and plugin permissions**. OpenAI’s new model, **GPT-6 Astra**, powers the destination environment, offering a **1.05M-token context window** and **128K-token output limit**. The article advises starting with the safest permission setting (*Ask for approval*) to avoid unintended actions during verification.

## Key points

- ChatGPT’s import feature moves up to 50 Claude Code chats from the last 30 days, plus settings and projects, but not one-to-one
- Authentication, environment variables, and permissions require manual recheck after migration—no full sync guaranteed
- GPT-6 Astra handles the imported content with a 1.05M-token context window and 128K-token output limit

## Why it matters

Teams switching from Claude Code must verify migrated settings and permissions manually, as OpenAI’s import tool lacks full compatibility or real-time sync. The move highlights gaps in cross-platform AI tool migration, forcing users to audit critical workflows post-transfer.
