@github @AnthropicAI @code Fable 5 pricing is missing here docs.github.com/en/copilot/ref…

@github @AnthropicAI @code 1000 Credit - #TokenTax @FTC we can’t afford this anymore.

@github @AnthropicAI @code With what tokens?

@github @AnthropicAI @code Yeah clearly will I use it that I reaching my rate limit from enterprise seat in 12 hours instead of 24h like at the 1.6? Nice 👍 @code @github

@github @AnthropicAI @code @burkeholland y'all need to redo your live stream competition now See what kind of bird this one makes

@github @AnthropicAI @code Fable 5 in Copilot now. The tools keep getting better faster than I can keep up.

@github @AnthropicAI @code $50 for Fable 5? That's a luxury price for a coding assistant...might as well hire a developer at that rate.

@github @AnthropicAI @code Yeah I've been using it pretty fast and it's very good. It's basically mostly for agentic work okay?

@github @AnthropicAI @code My AI credits are not emotionally or financially prepared for this.

WC soccer is here. Make your picks.

@github @AnthropicAI @code nice joke. please try and use but you can't lmao

@github @AnthropicAI @code Fable out price ($50) is kind of emotional damage even if you’re wealth person or live inside SF area.

@github @AnthropicAI @code FFS what's the point of enabling it when a single session will wipeout all credits

@github @AnthropicAI @code 1 prompt would cost 50 AI credits correct

@github @AnthropicAI @code I would need to sell both of my kidneys to use it

@github @AnthropicAI @code Anthropic's newly launched Claude Fable 5 (the first of their Mythos class) is rolling out in GitHub Copilot today for long-horizon, autonomous coding.

@github @AnthropicAI @code lol, u update very fast in this one github thanks

@github @AnthropicAI @code Github knows

Our delivery comes with a genius. Go learns what you like, builds your cart in seconds, and gets it all to your door in as fast as 15 minutes.

@github @AnthropicAI @code Claude Fable 5 accelerates autonomous coding

@github @AnthropicAI @code Good for long and complex coding tasks.

@github @AnthropicAI @code 长任务如果真稳了，日常写代码会省不少心力

@github @AnthropicAI @code Try it now in GitHub Copilot, if you have $5k to blow on usage in an afternoon.

@github @AnthropicAI @code copilot has become very costly. I closed my subscription there and switched to claude itself.

@github @AnthropicAI @code Copilot just went from useful to luxury item overnight. New policies made it insanely expensive not worth it anymore

@github @AnthropicAI @code One hi to Fable in github cleared my monthly budget, nice🤣🤣

@github @AnthropicAI @code We are still only getting a safeguarded version of Mythos. haybowena.com/claude-fable-5…

Homeowners overpay on property taxes every year because they don’t know how to challenge their assessment. The county won’t send you a check—and the appeal process is a pain. We make it easy. See how much you can save.

@github @AnthropicAI @code prolly at 39x usage. Might ask it to read Claude.md before you run out of usage if you’re lucky

@github @AnthropicAI @code Its available in copilot? Dayum whats the pricing? 30x per request? So 5 prompts and we're done

@github @AnthropicAI @code Is there anyone able to use this, I had a pro+ sub and got exhausted of credits on day one.

@github @AnthropicAI @code LOL you think people are still using github copilot, thats cute.

@github @AnthropicAI @code Claude Fable 5 is one of those releases that quietly changes product roadmaps overnight. But still the difference huge, can't even imagine mythos compare to fable

@github @AnthropicAI @code The whole tech community has gone bonkers with this absolutely crazy model from @AnthropicAI @claudeai

@github @AnthropicAI @code claude mythos (the ultimate tokens consumer) +github copilot (the worst heavy tasks token consumer)

@github @AnthropicAI @code Good luck sending a single prompt that burns your entire budget with your new billing system. Even Claude is cheaper. Thank God I didn't purchase the annual plan.
