What Is the Difference Between ChatGPT and Claude?
ChatGPT (OpenAI) and Claude (Anthropic) are the two leading AI assistants in 2026. ChatGPT (GPT-4o family) is strongest at tool use, multimodal input, image generation, and broad ecosystem integrations. Claude (Sonnet/Opus family) is strongest at long-context document analysis, nuanced prose, careful reasoning, and reduced hallucination rates. Both cost ~$20/month on consumer plans or pennies per query via API. Prompt Anything Pro supports both with a one-click model switcher.
- ChatGPT (OpenAI, GPT-4o family) leads on tool use, multimodal input (images/audio/video), image generation, and the broadest plugin ecosystem.
- Claude (Anthropic, Sonnet family) leads on long-document analysis (200K+ token context), nuanced writing, careful reasoning, and lower hallucination rates.
- Consumer plans: ChatGPT Plus and Claude Pro both cost ~$20/month. API access via BYOK is typically $1-5/month for moderate use — meaningfully cheaper.
- You don't have to pick: Prompt Anything Pro supports both providers via BYOK, switching models per-prompt with a single click.

Key Strengths of Each Model
- 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)
- 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
