Highlights
Best Overall
ChatGPT Plus presents the best mix of model intelligence and chatbot features. With access to GPT-4o and the widest range of features from web search to image generation to data analysis capabilities, ChatGPT Plus remains the best all-around paid chatbot.
Best Free
ChatGPT Free gives limited access to OpenAI's leading frontier-class model, GPT-4o, and near-unlimited access to GPT-4o mini. Within the ~6 messages per hour users are granted with GPT-4o, ChatGPT Free has full access to the wide feature set of ChatGPT Plus and is the best free AI chatbot experience.
Best For Images
Poe Pro includes access to FLUX.1 [pro], the leading image generation model in the Artificial Analysis Image Arena. Poe Pro supports a wide range of both AI language models and image generation models, including other leading image models such as Ideogram v2 and Playground v3 Beta.
Best For Coding
Claude Pro wins the 'Best For Coding' award with support for Claude 3.5 Sonnet, a foundation model with leading scores in coding benchmarks, and long context capability that lets developers work with extensive codebase context when programming with Claude.
Best For Long Context
Claude Pro supports by far the largest context window of any current consumer chatbot at 200k tokens (approx 150k words), alongside flexible file upload capabilities. With access to the Claude 3.5 Sonnet model, it is the best chatbot for long context reasoning and working with large files.
Best For Data
ChatGPT Pro combines the intelligence of GPT-4o with a Python code interpreter to deliver the best data analysis capability of all chatbots tested. Data files (eg. Excel and CSV) are uploaded directly into the code interpreter, and the model confidently writes code to analyze the data and create charts.

Intelligence
Quality Index: Foundation Model Intellingence and Reasoning
Effective Context Window
We found that the Effective Context Window available to many chatbot applications is much lower than the full context window of the underlying foundation model. Longer context windows allow users to input more information to the chatbot, including uploading longer documents.
Speed
Output Speed
For this comparison between chatbots, we manually measured the outputting time. We took multiple measurements at different times to attain a representative average but are not conducting ongoing real-time testing (unlike in our language model API benchmarking where we our systems test APIs 8x per day).
Features
Intelligence vs Feature Score
- Image Generation: 1 point
- Tools: 4 points (web search, code interpreter, data analysis, output HTML)
- Voice Features: 3 points (voice input, voice conversation, native voice-to-voice)
- Input Capabilities: 4 points (image upload, PDF upload, Excel/CSV upload, file source connect)
- Memory: 2 points (memory and chat history)
