ChatGPT launched in November 2022 and became the fastest consumer product to reach 100 million users. Built on OpenAI's GPT series of models, it remains the world's most recognized AI assistant.
The GPT-4o model (released 2024) introduced native multimodal capabilities — understanding text, images, and audio in real time. The o1/o3 reasoning models offer breakthrough performance on complex math and scientific problems.
Claude is built by Anthropic, an AI safety company founded in 2021 by former OpenAI researchers. Anthropic's Constitutional AI training approach aims to make Claude more helpful, harmless, and honest than traditional RLHF methods.
The Claude 3 family (Haiku, Sonnet, Opus) offers tiered capability/speed trade-offs. Claude's 200K context window — equivalent to a full novel — is unmatched for document-heavy workflows.
Claude wins for long-form writing quality and nuanced tone. ChatGPT is better for image + text workflows.
