Gemini was a strange model, with unique tuning that raised different issues and needs new techniques to properly prompt. Even Google themselves had problems getting it right. This prompt was designed from scratch to maintain proactive, entertaining writing and prevent it from losing coherence over time.
Primarily tested and tuned for Gemini Pro 1.0 and 1.5..
Usage notes
Keep Streaming and Use system prompt disabled to prevent refusals and hard-blocks.
Temperature value was tested to minimize formatting and coherence issues; be aware that increasing it will cause more undesirable swipes.
