Fable 5 and GPT-5.6 Check-In

What has your experience been with these models so far?

Tell me:

What are you building or testing?
Which model are you using?
What does one model do noticeably better than the other?
Where does the model still need the most improvement?
Which harness are you using? Cursor, Claude Code, Codex, or something else?

If you can, include a screenshot of the result. The most helpful screenshots show the task or prompt, the model’s output, and any errors or unexpected behavior.

Even a quick note helps everyone learn what these models are genuinely good at and where they still struggle.
