Frequestly Asked Questions
What are tokens? The units of what the AI sees
Tokens are the units of information that our AI models see when they look at text. Before the text is fed to the model, it's chopped up into discrete units, slightly shorter than words. For context, a 100-page book is about 30,000 tokens.
What is context window? How much text the AI can see
The “context window” determines how much of the story or role-play the AI can consider when generating its next response. It's like the AI's short-term memory.
We always give the AI the scenario definition (plot, characters, etc.) first. Then, the remaining tokens in the context window are filled with the most recent parts of the role-play or story. In role-play, you can even mark certain interactions as “sticky,” so they'll always be included, even if they're older.
Keep in mind that your stories and role-plays can be longer than the context window. The AI just won't be able to see all of it at once when generating new responses.
What are the different DreamGen models?
We've got three AI models ready to bring your stories to life:
- 🐣 opus-v1-sm (small): Swift, nimble, and perfect for simpler adventures. Plus, it has the longest context window on our paid plans.
- 🐓 opus-v1-lg (large): The balanced choice. Not too big, not too small, just right for most adventures.
- 🦚 opus-v1-xl (extra large): The heavyweight champ. Ideal for intricate, epic narratives.
Each model has its own unique “personality” and writing style, so make sure to experiment with all of them to find your favorite. And don't underestimate the small model - it's still got plenty of storytelling chops!
To pick a model, go to the “Model” settings. On the desktop the settings are in the sidebar, while on mobile you can access them via the “gearbox” button in the corner.
What are credits? Your AI adventure fuel
To generate responses, the models use “credits.” Different models use different amounts of credits per input & output token.
If you run out of credits, don't fret! Your monthly credits get reset at the start of each calendar month, and our credit fairy 🧚♀️ sprinkles extra credits into your account every day, so you can keep the adventure going all month long! This applies to all plans, including the free one.
Want to keep an eye on your credit usage? Check out your usage page to see how many credits you've used and how many you have left.
Also checkout our credit calculator on the pricing page, to estimate how many credits you'll need.
Example:
Assume you are writing a story.
On average, each "Continue" will require ~2500 input tokens and ~250 output tokens. This will cost 0.11 tokens with the opus-v1-sm model (as of 2024/04/01).
Therefore, if you have 200 credits, you can generate (200 / 0.11) * 250 ~= 45454 output tokens, which is roughly ~150 pages of an average book.
Is DreamGen Free?
Yes! DreamGen offers a generous free plan that lets you try out all of the features and models. The free credits reset at the start of each calendar month, and you also get extra credits every day if you run out.
