Anthropic ANTH.PVT https://finance.yahoo.com/quote/ANTH.PVT/ introduced Claude Fable 5.2 and Claude Mythos 5.2 AI models on Monday. The company's most powerful models, Anthropic says Fable 5.2 and Mythos 5.2 generate outputs 30% faster than their predecessors and offer improvements across coding, reasoning, and vision. Fable 5.2 is available across the company's platforms today. Mythos 5.2 is limited to organizations that are a part of Anthropic's Life Sciences and Cyber verification programs. The company says Fable 5.2 will also be less expensive to run than Fable 5.1. Fable 5.2 will now cost $8 per million input tokens and $40 per million output tokens. Fable 5.1 cost $10 per million inputs and $50 per million outputs. Tokens are a unit of measurement in AI that represent pieces of words or phrases you type or speak to a model and its responses. AI companies are engaged in a pricing war as models become more efficient and customers look for ways to save on AI services. Industry experts say that over time enterprises will likely rely on a mix of closed-weights models like Anthropic's and open-weights AI models to meet their needs. The idea is to avoid being locked into a single model vendor, while also being able to reduce overall costs.
