Cutoff Date

A knowledge cutoff date is the specific point in time after which an AI model no longer has updated information. This means that any data, events, or developments occurring after this date are not included in the model’s training data. For example, if the knowledge cutoff date for a model is April 2023, it will not have information on events that happened after this date.

Why Do AI Models Have Cutoff Dates?

AI models have cutoff dates for several reasons:

• Data Preparation: Gathering, cleaning, and formatting training data requires significant time and resources.
• Model Stability: A cutoff date ensures the model can be properly tested and stabilized without constant updates.
• Resource Management: Training large models is computationally intensive. Having a cutoff date helps manage these resources effectively.
• Version Control: It aids in maintaining clear version control by delineating what information is included in each version of the model.

Common Terms Explained

Deadline for the AI Model

The term “deadline for the AI model” typically refers to the final date by which an AI model must be completed, including its training and testing phases. This is not necessarily the same as the knowledge cutoff date but is related to project timelines and deliverables.

Cutoff Date for the AI Model

The cutoff date for an AI model is synonymous with the knowledge cutoff date. It indicates the last point at which the training data was updated. Any information beyond this date is not included in the model’s knowledge base.

Final Date for the AI Model

Similar to the deadline, the final date for an AI model can refer to the project’s completion date. It may also be used interchangeably with the knowledge cutoff date in some contexts, though it usually pertains to project timelines.

Last Date for the AI Model

This term is often used interchangeably with the knowledge cutoff date, signifying the last date up to which the AI model has been trained with updated information.

End Date for the AI Model

The end date for an AI model can refer to either the knowledge cutoff date or the project completion date, depending on the context. It generally indicates the end of a specific phase in the AI model’s lifecycle.

Cutoff Date for AI Model

This is another way of referring to the knowledge cutoff date. It marks the final point in time at which the AI model’s training data is considered current.

Knowledge Cutoff Dates for Popular AI Models

Here are the knowledge cutoff dates for some of the most popular AI models:

• OpenAI’s GPT-3.5: September 2021
• OpenAI’s GPT-4: September 2021
• Google’s Bard: May 2023 (Note: Bard can access real-time information from the web)
• Anthropic’s Claude: March 2023 (Claude 1) and January 2024 (Claude 2)
• Meta’s LLaMA: Generally around 2023 for the latest versions (specific dates may vary)
