Anthropic is an AI safety and research company founded by former OpenAI employees, including Dario Amodei and others. The company focuses on developing AI systems that are more interpretable, steerable, and aligned with human values. Their work primarily revolves around creating AI models that are safer and more transparent, with an emphasis on reducing risks that advanced AI systems might pose as they become more capable.

Their flagship model is Claude, which is an advanced language model designed to be more aligned with human goals and intentions, helping to avoid some of the potential misalignments or harms seen in other systems. Anthropic’s research also explores improving understanding of how these models work and ensuring they behave in predictable ways
Claude Models
Claude is the name of Anthropic’s family of language models. They’re designed to be more interpretable and steerable, with a primary focus on safety and alignment with human intentions. The Claude models aim to reduce harmful outputs or unintended behaviors that can arise in advanced AI systems.
Here’s a quick overview of the Claude models:
- Claude 1: Released in early 2023, this was the first iteration of the Claude model. It was a breakthrough in terms of natural language understanding and generation, with a particular emphasis on safe behavior and user control.
- Claude 2: Released in mid-2023, Claude 2 brought significant improvements over the first version, including better performance on tasks like summarization, reasoning, and more coherent dialogue. This model also incorporated feedback from real-world use to enhance safety and reduce harmful outputs.
- Claude 3: Released in 2024, Claude 3 further refined the model’s performance, making it more effective in handling complex tasks, like multi-turn conversations or nuanced reasoning, while still prioritizing safety. This version also integrated better fine-tuning to avoid generating biased or harmful responses.
Anthropic’s Claude models are built with a core focus on understanding and responding to human instructions in a way that aligns with ethical guidelines and reduces potential risks. Their design incorporates the principle of constitutional AI, where the models are trained with an ethical framework to ensure they are more likely to behave in desirable, human-aligned ways.
These models are often used for a variety of tasks, including conversation, coding assistance, content generation, and more.

Claude model pricing
The Claude models are available through Anthropic’s API and managed platforms such as Amazon Bedrock and Google Cloud’s Vertex AI.
Here’s the Anthropic API pricing:
- Claude 3.5 Haiku costs 80 cents per million input tokens (~750,000 words), or $4 per million output tokens
- Claude 3.7 Sonnet costs $3 per million input tokens, or $15 per million output tokens
- Claude 3 Opus costs $15 per million input tokens, or $75 per million output tokens
Anthropic offers prompt caching and batching to yield additional runtime savings.

Prompt caching lets developers store specific “prompt contexts” that can be reused across API calls to a model, while batching processes asynchronous groups of low-priority (and subsequently cheaper) model inference requests.
