For whatever reason I've preferred, at least so far, Fable to 5.6. I've spent the time since Fable's return being very cautious about when and how I use it, whereas with 5.6 (especially given OpenAI's generous limit resets) I'm pretty liberal about using it for lots of things that in the long run I could do with a less capable model.
Psychologically, I think that approach has made me value the delicate, ephemeral creature that is Fable more than I otherwise might. I don't know if that was Anthropic's plan, but if it was it worked on me at least.
But there's a limit to how many times they can play this card. Eventually either Fable has to blow me away so much that it justifies the API spend (it hasn't yet), or I have to decide that I can't rely on it, and I develop an approach that leans on it less heavily.
I don't know when we hit the tipping point from scarcity increasing perceived value to uncertainty reducing real value, but it can't be that far away.
Can Anthropic please just decide on what their plan is with Fable instead of kicking the can down the road last-second every time and consequently destroying all notions of being able to plan out one's weekly usage expenditure?
Oh gosh, that would be so nice. The triple whammy of (a) two layers of annoying timed usage windows, (b) constantly changing model availability windows, and (c) random unpredictable usage resets, is absolutely brutal for anyone who is trying to plan methodically and be efficient.
One minute I'm trying to use an entire week's worth of quota in less than 24 hours, then moments later I read the deadline has been punted and I have only 25% remaining to last me an entire week. This alone is enough for me to switch back to Codex once my current Claude sub ends.
I've been trying Fable 5 and GPT 5.6 Sol last few days. My impression is that Sol consumes a lot less tokens that Fable 5 being comparable. Gpt 5.6 Sol can be run sustainably on one 20x plan. Fable 5 requires 2-3 20x plans to be run sustainably.
I think the best move move for Anthropic would be to release an Opus 5 that is actually as cheap as Sol and comparably good. They have released a Fable 5 and Sonnet 5 so that seems like a possible move but I'm not sure whether the Opus 5 they got is already at Sol level.
Claude Code terminal is still better than Codex CLI though as an harness. Claude code Ultramode + workflow is unmatched by Codex harness yet in my experience.
How many of you actually need the SOTA level intelligence of Sol and Fable? What kind of tasks do you use it for, and what did you do 6 months ago when SOTA models were as intelligent as today's B team?
The other day I tried a 31B model from a Canadian company and felt this is good enough for 80-90% of my tasks.

Deeply unserious company, flip flopping on policy every week with ludicrous, sometimes invisible, guard rails on their top model. Imagine trying to make business decisions about AI use with this.
I love Fable for many things including coding but I cannot justify basing any internal AI tools or LLM powered products on top of Anthropic's offerings.

We should be insulated by this tbh, I'm migrating to open AI while this continues
THEIR PLAN IS TO FIND AS MANY WHALES AS POSSIBLE. Why do you ask?
Please explain for us simple folks
So, do you want me to trust technology you will shut down for some reason in random time? No, thanks :)

Finally, I can sleep... I'd been working non-stop all weekend to use Fable before it disappeared tomorrow. Now, please, a reset. ;)

Keep using Fable. Don't think about using GPT 5.6 Sol
Sweet! Safeguards seem a bit over-tuned this morning, it was working on Lenia all night and now it won't touch it.
Nobody could have predicted this.
Apparently, not even Anthropic, otherwise they could have done us all a favour by announcing it sooner.
