ChatGPT vs Claude — Attribute Category Vocabulary
Taxonomy of attribute categories used to classify comparison data for ChatGPT vs Claude.
Which AI is better for analyzing long documents?
Claude is significantly better for long-form document analysis. Its 200,000 token context window can process approximately 150,000 words in a single request—equivalent to a full novel or 500-page research report. ChatGPT's 128,000 token limit handles about 96,000 words. For legal contracts, scientific papers, or codebase analysis, Claude's extended context is a decisive advantage.
Which is more accurate for factual questions?
Claude achieves 94.4% accuracy on the MMLU benchmark (a standard test of broad knowledge across 57 disciplines) compared to ChatGPT's 92%. More importantly, Claude demonstrates a 3-5% hallucination rate on factual queries versus ChatGPT's 8-12%. For tasks requiring high accuracy (research, legal analysis, medical information), Claude's Constitutional AI training provides measurably better reliability.
Which is more affordable for heavy API usage?
Claude's pricing is substantially lower, especially for high-volume use. Claude Haiku costs $0.80 per 1M input tokens versus ChatGPT's $15 for GPT-4 Turbo—an 94% cost savings. Even Claude Opus (the most capable model) at $3 per 1M tokens is 80% cheaper than GPT-4 Turbo. For developers processing thousands of requests monthly, Claude's pricing advantage could save thousands of dollars annually.
Can I use ChatGPT for image and voice interactions?
Yes, ChatGPT natively supports both capabilities. You can upload images for analysis, and ChatGPT can generate images using integrated DALL-E 3. Voice input/output is available on mobile and desktop apps for GPT-4 Turbo and newer models. Claude does not offer either feature—you would need to use separate tools for image generation or voice interaction.
Which has more third-party integrations?
ChatGPT has substantially more integrations due to its 13x larger user base and longer market presence. OpenAI's official directory lists integrations with 10,000+ applications across productivity, CRM, analytics, and development tools. Claude integrations exist but are fewer in number. If integration ecosystem is critical for your workflow, ChatGPT offers significantly more plug-and-play options.
