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.

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

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?

Keep using Fable. Don't think about using GPT 5.6 Sol

Question to HN:

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.

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.
