Short answer: you are cooked. The current old language model (it's in the process of being replaced, but we don't know when) has a 4k context window token, aprox 2 pages of text. This is the what the model can remember. Best option is to use the non-fancy AI Chat (https://perchance.org/ai-chat) put less than 1k tokens in your character description or even better just put the essential, and put the rest of your lore in the Scenario & Lore and pray to the Old Gods you don't exceed 3k-4k characters or you will experience a new universe of roleplaying...the goldfish memory experience. I love Perchance but I gave up months ago about doing roleplay with strong scenarios and world building because with 4k tokens it's simply impossible. We all hope the new model will have at least 10k tokens window so you will have the bare minimum to create cool worlds and scenarios without having to describe each character in one line of text. More than 20k tokens will be fucking amazing...but one only can dream.
