Claude

Claude Fable 5 and Claude Mythos 5 Today we're going to dive into Claude Fable 5, a "kitchen sink" model that's ready to tackle your prompts. Claude Fable 5 is available everywhere today. Claude Mythos 5 is restricted to researchers (strict usage and chemistry safeguards apply), only our enterprise customers. Pricing for both models is $15 per million input tokens and $60 per million output tokens. Developers can use Fable 5 via the Claude API. We expect Fable 5 and Mythos 5 to be high-performing, and we're rolling out the Claude API and consumption-based enterprise plans. Fable 5 is fully available on the Claude API and consumption-based enterprise plans. Fable 5 is mission-critical than Mythos, so we're rolling out more conservatively, in stages. From today through June 22, Fable 5 is included on Pro, Max, Touch, and will be available on the Claude API and consumption-based enterprise plans. On June 23, we'll remove Fable 5 from those plans. Using Fable 5 will require the Claude API or consumption-based enterprise plans. We expect that when sufficient capacity allows us to drive our rate up, we'll be able to offer a standard part of active workflows. We intend to drive our rate up as quickly as we can. Throughout this period, we'll communicate any changes ahead of time, so we know what to expect. Edit June 9, 2020: Updated the discussion of API to note that the candidate were developed by Opus, Prosumer.
