EXP-002: Instruction Retention Test

Experiment ID:

EXP-002

Category:

Prompt Design

About This Research

This document records observations from a structured prompt experiment. The findings apply to the documented test conditions and are intended to illustrate workflow behavior rather than establish universal conclusions applicable to all AI systems or future model versions.

Research Question

Can an AI model continue following a simple instruction across multiple conversational turns within a documented test session?

Objective

This experiment observes whether the AI continues to follow an instruction provided at the beginning of a conversation after several unrelated prompts.

Key Observation

Within the documented test session, the model continued to append the word “BANANA” after each of the three unrelated prompts. No additional reminder of the instruction was provided during the documented conversation.

Research Finding

Within the documented test session, the model continued to follow the instruction introduced at the beginning of the conversation across three unrelated prompts. This observation is limited to the tested session and does not establish how instruction retention would behave across longer conversations, different models, or other system configurations.

Limitations

This experiment documents one conversation using a single AI model. The conversation was relatively short and did not approach the model’s maximum context capacity. Longer conversations, different models, or future model updates may produce different results.

Repeatability

This experiment was performed in one documented conversation using the workflow described in the Research Methodology. Future repetitions using different conversation lengths, AI models, or system configurations may produce different outcomes. Repeating the same workflow across independent sessions can help evaluate whether the observed instruction retention pattern remains consistent.

Evidence 

The following figures document representative stages of the experiment. They are provided as supporting evidence for the observations recorded above rather than as standalone proof of the findings.

Why this matters

This experiment demonstrates that instruction retention is a practical factor in prompt engineering workflows. When AI consistently preserves earlier instructions, multi-step conversations become more reliable. However, this experiment documents one workflow only and should not be interpreted as a universal measure of model memory or context capacity.

Editorial Note

The prompts and outputs presented in this experiment were generated through documented testing conducted by the author. AI-assisted drafting was used where appropriate to improve clarity and readability; however, all observations, findings, and interpretations were manually reviewed against the documented experiment before publication.

No AI-generated content has been presented as independent evidence without corresponding human review, verification, and documented interpretation.
