Free Access Conditions: The bet resolves YES if OpenAI offers GPT-4 (including variants like "GPT-4-lite" or similar) for free to ChatGPT users before April of 2024 under any of these conditions:

• Permanent free access with limited usage (e.g., capped messages)

• Limited trial access totaling four weeks (not necessarily consecutive)

• Access through custom GPTs using GPT-4 on the GPT-Store.

Exclusion Criteria

• Trials requiring credit card information and leading to automatic charges after the trial do not count towards this bet's resolution.

• Access to GPT-4 through other platforms like Bing does not count.

Edge Cases

• If a trial that doesn't lead to automatic charges starts in March and ends in April, this would count towards resolving the market to Yes.

• If OpenAI requires a payment method for verification and doesn't apply automatic charges, then this would count toward resolving this question as Yes. However, this is highly unlikely since they use phone numbers for verification.
