ChatGPT vs. Claude

Overview

The engine behind the fastest growing product of all time, ChatGPT is the successor to OpenAI's InstructGPT model. Originally based on GPT-3, ChatGPT now provides options for users to either use its GPT-3.5 or GPT-4 base model. In mid-2024, GPT-4o with multimodal support was released, topping various benchmarks. Following 4o, o1 and its successor o3 were released as reasoning models with adaptive inference-time compute.

Initial release: 2022-11-30

Overview

Created in part by several of the developers of OpenAI's GPT-3, Claude is Anthropic's LLM trained with its research in developing helpful and safe AI systems.

Claude is Anthropic's flagship LLM and, as of April 2024, the most competitive cloud LLM offering alongside OpenAI's GPT series. Highly capable, Claude was also originally trained using Anthropic's "Constitutional AI" feedback method. Since the initial release, Anthropic has continued to improve the performance and cost of Claude, most notably in March 2024 with the release of the Claude 3 model family: Haiku, Sonnet, and Opus, and more recently in June 2024 with the release of Claude Sonnet 3.5, surpassing Claude 3 Opus and at a much lower cost.

Initial release: 2023-03-14
