A conversation with Boris Cherny and Cat Wu on the path from Claude Code to Claude Tag, and how it spread from engineering to the rest of Anthropic. Claude Fable 5 is now available in Claude Tag.

You guys are crossing the line from an inference provider to a straight up competitor to all your customers. Claude Tag just raises so many conflict on interests, privacy, security, and intellectual property concerns. It would be one thing if you guys offered this locally...

built this with Fable 5

Can you add claude tag to X so we can have it do a comment war vs @grok

It's wild how "engineering tools" always end up as the company's main product once the rest of the office realizes they can't live without them. Give it 6 months and we'll be hearing about how the HR team accidentally built a new feature using Tag.

usage limit reset please

I hope you are watching and realize that Fable 5 has been nerfed so much that nobody is going to miss it if and when it's gone this time.

Guys!!

the first 6 seconds (muted) freaked me out

I need a reset

Crazy how far we've come in a 3 year timespan Cant even imagine how far we will reach within 3 more years

can u please fix this i need to know thanks

Fix this! I can’t use Fable on LOW MAX!

Claude Tag’s leap from Claude Code to Claude Fable 5 redefines enterprise AI collaboration now engineering and every team can harness autonomous agents for complex workflows. Straightforward, powerful, and built for scale: this is the future of AI driven development. #ClaudeTag #ClaudeFable5 #Cybernorse

why is my usage gone every 15 mins 🫩

how many times fable is better than opus?

It would be better to talk about how to optimize their models and not eat all the tokens in one request with Fable 5🫪🥹🫪🥹

@Claude get 100Mil ARR, make no mistakes

Now can I please talk to someone in sales instead of your incessant "loop" that makes me fill out a form, says someone will be in contact and nothing. I've sent in 3 forms and waited 1.5 months. Your Fin is absolutely useless and loops me back to a fricking form too. Im already in Max, don't need enterprise I believe and use the api through AWS but would love the direct api via Anthropic but require a baa. I'm trying to scale my business so would love to speak with sales to determine the right path. DM if there is anyone besides Dario, Daniela and Boris at the company. @DarioAmodei @DanielaAmodei @bcherny

interesting. was Claude Tag built for non-engineers from day one, or did it grow out of internal usage?

fable 5 got export banned faster than most models get benchmarked. thats the real flex

Project Instructions are being misinterpreted as user messages. This started today and affects multiple Projects. Claude repeatedly thinks I am sending prompts and enters loops. Please fix this.

How much of Claude developments come from user projects? @grok

i'd like to see some actual metrics on how claude fable's performance has improved with the switch to claude tag, not just marketing fluff

Why do your models just start from scratch when the usage limit ends. Make it possible to continue working on the request in 5 hours

You're trying to limit open source models. Don't be evil.

After this point—when sufficient capacity allows us to do so—we aim to restore Fable 5 as a standard part of subscription plans. We intend to do this as quickly as we can.

My favorite part of this is how you guys act like you made this and didn’t just steal it from your users. Which you so obviously did. Who’s the striver Asian that found the chat

This dude is very funny, I guess Look at his PF @bcherny

Is #Claude TAGS really that great!? Initially I though it was not; but after hearing points from @theo - #TAGS seems simple but have some level of complexity that they have made accessible to everyone!

wait claude tag is actually what they called it the internal adoption arc is always the wildest part of these stories

This is... an odd coincidence, but my cat's (RIP) name was... Wu.

I have been using AI under Sudowrite and externally from it to help write my Fiction since 2022. It's been a bit rough around the edges to say the least kind of journey. Opus 4.8 took all those previous attempts and wrote something much more organized. Fable 5 just cleaned it up even more. Impressive.

From Claude Code to Claude Tag... watching internal tools evolve into entire ecosystems is fascinating 📈✨
