Anthropic launched a new AI model Thursday which it says is its “most intelligent model yet.” The new model, Claude 3.5 Sonnet, is reportedly twice as fast as Claude 3 Opus, the company’s previous best-in-class AI, and five times cheaper to run. Following a trend set by its competitor OpenAI—which just last month released the newest version of ChatGPT, GPT-4o—Claude 3.5 Sonnet is free for all users on the web and iOS to access.
