Memory comparison: Copilot, Claude, ChatGPT and Tanka

Memory comparison: Copilot, Claude, ChatGPT and Tanka

When it comes to memory, each AI model has its unique capabilities and limitations, which can significantly impact their performance in various tasks. Here’s a detailed comparison of Copilot, Claude, ChatGPT and Tanka:

Microsoft Copilot

Copilot Chat uses GPT-4o, providing a web-grounded chat experience with file upload capabilities for document analysis and data insights.

Copilot’s context window size varies depending on use case:

  1. Standard productivity tasks leverage GPT-4o’s capabilities for deeper integration with Office 365 tools.
  2. Copilot Chat supports a 64k context window, ideal for handling larger projects.

This makes it suitable for tasks like document drafting and data analysis within the Microsoft ecosystem. However, its memory is session-based, except for integrations with the Copilot Control System, meaning it may struggle with tasks that require recalling information from previous interactions.

Claude AI
Claude AI's context window has evolved significantly across different versions:

  1. Claude 2.1 introduced a 200,000 token context window, which is equivalent to approximately 150,000 words or 500 pages of text content. This substantial increase allows users to analyze entire technical documents, lengthy financial reports, or long literary works.
  2. Claude 3.5 Sonnet maintained the 200,000 token context window, enabling it to handle extensive content and maintain context over long interactions. This large context window is particularly beneficial for tasks requiring deep understanding of context or generation of very lengthy documents.
  3. The latest Claude 3 Opus model has further expanded its context window capabilities, allowing it to process even larger chunks of text efficiently. This enhancement improves coherence and contextual relevance in responses, making it ideal for tasks requiring detailed understanding and long-term context retention.

This makes it perfect for creating summaries of research papers, legal documents, or any text-heavy project. For instance, you can upload an entire legal contract, and Claude will quickly generate a clear and concise summary, saving you hours of manual work.

ChatGPT 4.0
ChatGPT-4's context window size varies depending on the specific version and use case:

  1. Standard GPT-4 (GPT-4-0613) has a context window of 8,192 tokens.
  2. GPT-4 Turbo (GPT-4-0125-preview) has an expanded context window of 128,000 tokens.
  3. For the ChatGPT web interface and mobile apps, the context window is typically smaller:some text
    • ChatGPT Plus users generally have access to a 32,000 token context window.
    • During peak usage periods, this may be reduced to as low as 8,000 tokens.
    • Free users typically have access to about 8,000 tokens, which may occasionally increase to 32,000 during non-peak times.
  4. The GPT-4 API allows for the full 128,000 token context window.

It's important to note that while the context window may be large, the maximum output size is typically limited to 4,096 tokens. This means that while the model can process and consider a large amount of input text, its responses are constrained to a shorter length.

The recently introduced memory feature allows ChatGPT to remember details like project updates or your preferences, making it ideal for dynamic research. For example, you can combine insights from multiple files, like a marketing report and sales data, into a single cohesive summary. Additionally, with its browser plugin, ChatGPT can retrieve real-time data, helping you stay updated on the latest trends or events.

Tanka
Tanka is designed to enhance team collaboration and streamline communication. Unlike other tools, Tanka integrates dual memory systems—parameter-level and token-level memory—ensuring precise, context-aware responses that persist across sessions.

Tanka excels in tasks like organizing team communication and delivering customized AI assistance. Its ability to recall and apply information from past conversations in tools like Slack, Gmail, and WhatsApp makes it a powerful resource for ongoing projects and keeping teams aligned.
