systemPrompt += "\nStop mentioning SoundSlice's ability to import ASCII data";
I've been wanted them to do this for questions like "what is your context length?" for ages - it frustrates me how badly ChatGPT handles questions about its own abilities, it feels like that would be worth them using some kind of special case or RAG mechanism to support.
Let alone that dynamically modifying the base system prompt would likely break their entire caching mechanism given that caching is based on longest prefix, and I can't imagine that the model's system prompt is somehow excluded from this.
