It is theorized that OpenAI may time the release of GPT 5.6 in Codex to convert people who have lost access to Fable, so this is an interesting game theoric consequence.
It is, many people are hungry for GPT-5.6, considering it is supposed to be Fable class, with lower costs. Many Claude users were ready to jump ship.
It was foreseen.
It's also possible that giving access to Fable when lots of people have been taking time away from working on things (4th July, World Cup, etc) meant they didn't spend much time with it.
