GPT 5.6 SOL (Plus subscription) vs Fable (Pro subscription) - who gives you more tokens in chat?

I know, I know, this is a sub about local LLMs. I get it. But it is also the only sub I trust, because there are no OpenAI or Anthropic fanboys telling me what to choose from. (There are probably some here as well, but.. yeah)

So I wondering if It's worth to give GPT 5.6 a try with the Plus subscription in order to use a frontier model with more tokens per $ than I can with Fable?

OpenAI Plus costs 23€ and Pro from Anthropic costs 15€

I need it to discuss coding architecture with a lot back and forth and posting documents or code as well to discuss about.
