OpenAI APICAUTIOUS-BUY
The default LLM API, with shrinking moats

Choose Claude Pro / Enterprise if...

For deep research, analyzing multiple documents simultaneously, complex reasoning tasks, or when you need more thoughtful/nuanced responses than ChatGPT.

Avoid Claude Pro / Enterprise if...

When you need real-time web search or multimodal capabilities (images, charts). Cannot execute code or access external tools.

Developers building AI products who want the largest ecosystem, most tutorials, and most third-party tooling. Best for multi-modal applications.

Avoid OpenAI API if...

Applications requiring the longest context window — Claude handles 200K tokens vs. GPT-4o's 128K.
