Feature Request: Context Window Warning / Meter before hitting "The conversation is too long"

Problem: Currently, when a conversation reaches the maximum token context limit, ChatGPT suddenly locks the chat input with the message: “The conversation is too long, please start a new one.”

Because there is no advance warning, users working on extensive projects (e.g., long-term document analysis, coding, or narrative writing) are often caught off guard. Once the error appears, the input box is essentially disabled, preventing the user from asking ChatGPT to generate a handoff summary of the accumulated state to copy into a new thread.

Proposed Solution:

  1. Visual Context Warning / Meter: Display a subtle indicator (e.g., a progress bar or warning banner at 80%–90% capacity) letting users know the conversation is approaching its length limit.

  2. Automated Handoff / Summary Prompt: When the limit is near, offer a one-click button such as “Summarize & Continue in New Chat” that automatically generates a concise project summary and opens a fresh thread pre-loaded with that context.

Benefits:

  • Prevents unexpected workflow interruptions during complex tasks.

  • Allows users to summarize key decisions and context before the thread is locked.

  • Improves user experience by making chat transitions seamless rather than reactive.
