Anthropic's Claude AI Models

Anthropic has developed AI models Claude, such as Haiku, Sonnet, and Opus, for various tasks. Sonnet, the most advanced, offers activatable reasoning. The models have different features and pricing, but there are risks related to the use of potentially copyright-protected data.

Anthropic's Claude AI Models

Anthropic is one of the leading companies in the artificial intelligence (AI) sector and has developed a series of generative models called Claude. These models can perform various tasks such as writing emails, solving math problems, and generating captions for images. With the rapid expansion of Anthropic's model ecosystem, it can be challenging to navigate the different versions of Claude and their functionalities. Therefore, it is helpful to have a guide summarizing the features of each model, which will be updated regularly with new versions and updates.

Claude models are named after literary works: Haiku, Sonnet, and Opus. The latest are Claude 3.5 Haiku, a lightweight model, Claude 3.7 Sonnet, a hybrid reasoning model that is currently Anthropic's flagship model, and Claude 3 Opus, a large model. Interestingly, while Claude 3 Opus is the largest and most expensive model, it is currently the least capable among the Claude models. However, this is expected to change with the release of an updated version of Opus. Claude 3.7 Sonnet stands out because it allows users to activate its reasoning capabilities, enabling the model to "think" for a short or long period before providing an answer.

When reasoning is turned on, Claude 3.7 Sonnet can take anywhere from a few seconds to several minutes to analyze the user's prompt, breaking it down into smaller parts and checking its answers. Even without reasoning enabled, Claude 3.7 Sonnet remains one of the top-performing AI models in the tech industry. In November, Anthropic launched an improved version of Claude 3.5 Haiku, which outperforms the previous Claude 3 Opus in several benchmarks, although it cannot analyze images like the other models. All Claude models have a standard context window of 200,000 tokens, which is equivalent to about 150,000 words. While they cannot access the internet or generate complex images, they can follow multistep instructions and produce structured output in formats like JSON.

Regarding pricing, Claude models are available through Anthropic's API and managed platforms such as Amazon Bedrock and Google Cloud's Vertex AI. The rates vary depending on the model, with Claude 3.5 Haiku costing 80 cents per million input tokens, while Claude 3.7 Sonnet and Claude 3 Opus have higher costs. Anthropic offers plans for individual users and businesses looking to interact with the models via web and mobile apps. Users can choose between free plans with limitations or paid subscriptions that offer additional features and higher limits. However, it is important to note that using generative models like Claude carries risks, including errors in summarizing and potential issues related to copyright of the data used for training.
