The Problem We Were Actually Solving
In reality, we were tasked with solving a complex problem of keeping users engaged without sacrificing their experience. We had a finite set of resources to work with, and our team was comprised of experienced engineers with varying degrees of familiarity with AI. What was clear was that we needed a system that could generate unique puzzles under the constraints of tight latency and reliability.
To achieve this, we started by scouring the internet for off-the-shelf AI solutions. We were told that we needed to integrate a cutting-edge AI engine that could generate puzzles at scale. What we didn't realize was that this would lead us down a rabbit hole of unrealistic expectations and poor architecture decisions.
What We Tried First (And Why It Failed)
We started by integrating a popular large language model (LLM) into our system. We thought that this would solve our problem of generating engaging puzzles automatically. What we quickly discovered was that the output was not only unengaging but also often nonsensical. We were seeing hallucination rates of over 20%, which was unacceptable given our requirement for reliability.
We tried to tweak the model, adjusting parameters and hyperparameters to fit our specific use case. However, this led to more problems. We started seeing oscillations in the output, with the model producing identical puzzles repeatedly. We thought that we were making progress, but in reality, we were just masking the underlying issue of overfitting.
The Architecture Decision
It wasn't until we took a step back and reevaluated our architecture that we began to see real progress. We realized that our LLM was not the solution to our problem but rather a symptom of it. What we needed was a more robust architecture that could take into account the nuances of the puzzle generation problem. We decided to implement a hybrid approach, combining rule-based generation with a scaled-down version of our LLM.
This decision paid off in spades. Our hallucination rates dropped to under 5%, and our engagement metrics saw a significant boost. What was more important, however, was that we learned a valuable lesson about the importance of architecture in AI systems.
What The Numbers Said After
After deploying our revised system, we saw significant improvements in our key metrics. Our engagement rates increased by 25%, and our puzzle generation rate saw a 30% boost. More importantly, our users reported a significant improvement in their overall experience, citing puzzles that were not only engaging but also challenging and fun.
In terms of actual numbers, our system was generating an average of 500 puzzles per minute, with a latency of under 200ms. This was a far cry from the 5-second latency we had been aiming for, but it was a significant improvement over the 30-second latency we had seen with our original LLM-based approach.
What I Would Do Differently
Looking back on our experience with the Treasure Hunt Engine, there are a few things that I would do differently. Firstly, I would have taken a more nuanced approach to our AI integration from the start. We could have avoided the pitfalls of over-promising and under-delivering by taking the time to understand our specific use case and requirements.
Secondly, I would have invested more time in evaluating our architecture decisions. We could have avoided the pitfalls of oscillations and hallucination rates by taking a more thoughtful approach to our system design.
Lastly, I would have prioritized testing and validation from the start. Our original LLM-based approach would have been rejected at the first sign of trouble if we had taken a more rigorous approach to testing and validation.
