Many users expressed excitement over Anthropic's planned Claude Mythos 5 model as a major capability jump, while others worried about high costs, vague timelines, and slow speeds in existing Claude versions.

@ai_with_gregor We may see a new Haiku at some point too as it is powering their voice mode afaik

@testingcatalog HERE WE GO

@testingcatalog Mythos is coming 🔥
Positioned in @mythosrouter

@testingcatalog I just noticed that Mythos actually made sense in the Haiku/Sonnet/Opus/Mythos logical progression ("Mythos is a worldview-based traditional story or body of mythology")

@testingcatalog Mythos 5 = Opus 5, and the current Opus models (since 4.7) are nothing but a new generation of Sonnet models.

@testingcatalog We know it will be beautiful but expensive :/

@testingcatalog it will be back soon...

@testingcatalog @grok verify

@testingcatalog it directly starts from claude mythos 5 ?
like seriously 5 ?
does that mean opus family is dead?

@testingcatalog Let's gooo, what's your prediction guys, next week or?

@testingcatalog they did say weeks... 😉

@testingcatalog seen it since 1h+

@testingcatalog haiku and sonnet are depreciated?

@testingcatalog mythos has entered the chat!

@testingcatalog wonder what slot a fourth family fills, haiku sonnet opus felt like a complete ladder already

@testingcatalog "Claude Mythos is planned to be released as its own model class, besides Haiku, Sonnet and Opus model families." what else did u except, sir?

@testingcatalog Ugh can we please get an update to Sonnet too? I really love the model and at this point my biggest issue with Claude is how slow Opus is compared to GPT.

@testingcatalog If Mythos is a separate Claude class, the naming alone hints Anthropic may be carving out a very different behavior profile.

@testingcatalog Imagine if this was just a prank to stir up hype on social media lol
