CHATGPT 5.6 IS OUT AND IT COULD COMPLETELY CHANGE THE BALANCE OF POWER The main feature is a context window of 1.5 million tokens Claude Fable 5 only has 1 million This means you can upload entire books massive PDFs and knowledge bases and the model performs just as well without losing quality On top of that GPT-5.6 is three times cheaper than Fable 5 more context better quality lower price For developers and companies working with large volumes of data this changes everything paying less for a model that holds more in its head at once is not just convenient it is a different economy And yes Fable 5 was just unblocked after government restrictions so now the two most powerful models are back in the game at the same time the competition is just getting started
