What Is the Difference Between ChatGPT and Claude?
ChatGPT (by OpenAI) and Claude (by Anthropic) are the two leading AI assistants, each with distinct strengths. ChatGPT excels at coding, tool use, and creative tasks, while Claude is known for longer context handling, careful reasoning, and nuanced writing. With Prompt Anything Pro, you can use both models side by side and switch between them depending on the task.

Company Background and Philosophy
OpenAI created ChatGPT and the GPT model family. They pioneered the consumer AI assistant space and have the largest user base. OpenAI focuses on building increasingly capable models with broad functionality. Anthropic created Claude and was founded by former OpenAI researchers with a focus on AI safety. Anthropic's approach emphasizes helpfulness, harmlessness, and honesty — which shows in Claude's tendency to be more measured and transparent about its limitations.
Key Strengths of Each Model
Both models are highly capable, but they shine in different areas.
- ChatGPT (GPT-4o) strengths — Code generation, tool/function calling, image generation (DALL-E), browsing the web, plugin ecosystem, multimodal input (images, audio, video)
- Claude (3.5 Sonnet) strengths — Long document analysis (200K token context), nuanced writing, careful reasoning, reducing hallucinations, following complex multi-step instructions
- Coding — Both are excellent. GPT-4o is slightly preferred for code completion and debugging. Claude excels at explaining code and writing documentation.
- Writing — Claude tends to produce more natural, less formulaic prose. ChatGPT is better at creative formats and structured content.
- Analysis — Claude's longer context window makes it better for analyzing entire documents, contracts, or codebases in a single prompt
- Accuracy — Claude is generally more conservative and will say "I'm not sure" rather than confidently stating incorrect information
Pricing Comparison (API vs Subscription)
Both providers offer subscription plans ($20/month for ChatGPT Plus, $20/month for Claude Pro) and API access with pay-per-token pricing. With Prompt Anything Pro's BYOK approach, you use API pricing, which is significantly cheaper for most users.
- GPT-4o API — $2.50 per million input tokens, $10 per million output tokens
- Claude 3.5 Sonnet API — $3 per million input tokens, $15 per million output tokens
- GPT-3.5 Turbo API — $0.50 per million input tokens, $1.50 per million output tokens (budget option)
- Practical cost — Most users spend $1-5/month on API usage vs $20/month for either subscription
