Anthropic Claude 5.2 launch: new models claim edge over GPT-6
The Anthropic Claude 5.2 launch adds Fable 5.2 and Mythos 5.2, which Anthropic calls its most advanced models, with lower API prices and responses up to 30% faster.
Anthropic launched Claude Fable 5.2 and Claude Mythos 5.2 on November 9, calling them its most advanced AI models yet.
API prices are $8 per million input tokens and $40 per million output tokens, down from $10 and $50 for the predecessors.
Anthropic says the models generate responses up to 30% faster and outperform OpenAI's GPT-6 Astra in several benchmarks.
Fable 5.2 is for general users with added cybersecurity and biology safeguards; Mythos 5.2 is for approved organisations in cybersecurity and life sciences.
The speed and benchmark claims are Anthropic's own; no independent testing was reported.
