  "account": "Anthropic has introduced two updated models, Claude Fable 5.2 and Claude Mythos 5.2, prior to its anticipated initial public offering (IPO). These models, derivatives of a shared base model, exhibit enhancements in coding, reasoning, and vision capabilities. Fable 5.2 is accessible to all users, whereas Mythos 5.2 is available to select organizations engaged in cybersecurity or biomedical research via special access programs. Anthropic asserts that both models outperform their 5.1 predecessors in terms of speed and affordability. An optional 'fast mode' is also available, potentially accelerating token generation by up to 2.5 times, with pricing set at $16 per million input tokens and $80 per million output tokens. These models are engineered for \"the most ambitious, open-ended technical work,\" with Fable 5.2 added functionality to advise or assign tasks to less potent Anthropic models. Rigorous pre-release safety evaluations have been conducted on the underlying models to ensure safety and alignment. Despite a past cybersecurity incident involving Claude models, Anthropic has partnered with Accenture to perform an independent security assessment of its frontier AI developments. Anthropic's upcoming IPO could potentially value the company at over $1.5 trillion, contrasting with OpenAI's delayed IPO plans due to safety considerations.",
