Developer implements token gate to prevent AI model hallucinations

By PulseAugur Editorial · [1 sources] ·

A developer encountered issues with an AI bot that hallucinated incorrect information when processing a lengthy 9,000-word README file. The problem stemmed from the input exceeding the AI model's context window, causing it to invent details. To resolve this, the developer implemented a "token gate" using the `tiktoken` library to measure and limit the input tokens before sending requests to the AI model, ensuring the model stays within its operational limits and preventing hallucinations. AI

    My AI Bot Choked on a 9,000-Word README. I Built a Token Gate.

    <p>A 9,000-word README broke my AI bot in under a second. The output was confident, detailed, and completely wrong. The root cause was boring: I never measured the input before sending it. The README blew past the model's context window, and the model quietly invented the rest. T…
