## In short

Fireship looks at Claude Fable 5.2 and Claude Mythos 5.2, which Anthropic released in the middle of its IPO roadshow, and at what the new models can do.

## What it is

'Did Anthropic just save its $1 trillion IPO?' went up on Fireship on 10 November 2026. The video covers Claude Fable 5.2 and Claude Mythos 5.2, which Anthropic released during a rocky IPO roadshow, and walks through what the two models can do.

## How it works

Anthropic's announcement describes Mythos 5.2 as the same underlying model as Fable 5.2 with lighter safeguards, open only to vetted cybersecurity and biomedical organizations. Fable 5.2 is the generally available version, priced at $8 per million input tokens and $40 per million output tokens.

## Why it matters

The title ties a model launch to Anthropic's stock-market debut: how well Fable 5.2 lands is part of the story Anthropic tells investors during the roadshow.
