If you've been following AI Dungeon for a while, you might have noticed that over the past two years our AI models have multiplied like hamsters. What started as a modest line-up of language models featuring just a baby griffin and a giant dragon has grown into quite an assortment of mythological beasts, ancient divinities and…spacecraft? It includes three sizes of snooty Pegasus siblings, two different versions of the recalcitrant flying Greek god with the sandals, a doddering, longwinded wizard and even a rickety old Imperial starfighter! While having lots of options sounds great in theory, the reality is that many of these models are showing their age. In AI terms, some of them are practically ancient—released way back in the mists of 2023.
Why Clean House?
For one thing, older AI models often can't compete with newer ones in terms of quality and efficiency. Models that were groundbreaking 18 months ago have been thoroughly outclassed by recent developments. Plus, maintaining all these models takes money and time that is better spent on developing and improving newer, more capable ones. There comes a point when a model is old enough—and little-used enough—that the resources needed to maintain it are no longer justified. A simpler line-up is easier for new users to navigate, making it more likely that players will find the models best suited to their interests.
Our Cleanup Strategy
We're making three types of changes today:
Rename
First, we're making some model names clearer and more intuitive. The most notable change is renaming "Dynamic Free" to "Dynamic Small" to reflect that many premium users also love the dynamic model at higher contexts (don’t worry—it’s still going to be available to free users!).
Deprecate
Some models are being marked as legacy options. They’ll still be available for now. Think of this as us saying, “Hey, there are better models out there!”
- Mixtral (superseded by Mistral Small)
- TieFighter (low usage, obsolete)
- MythoMax (obsolete base model)
- Pegasus 70b (superseded by our new finetunes of the Llama series)
- Original versions of Wayfarer and Mistral Small (making way for the updated versions)
Remove
Finally, we're “retiring” models that have been thoroughly outclassed:
- Pegasus 8B
- Pegasus 8x7B
We know a few of you will miss them, but their purpose is past, and it’s time for these winged friends to fly off into the sunset (plus their usage is low). Thank you, dear Pegasus, for the memories and adventures!
What This Means For You
If you're using any of the deprecated models, you don’t have to do anything for now, as they will continue to be available. If you’re using one of the deprecated or removed models, don't worry—we'll automatically transition you to a newer, more capable model. You're welcome to switch to a different model or back to a deprecated model if you prefer.
This cleanup makes room in our AI terrarium for new models…but I can neither confirm nor deny that other models are coming 😉
