Space Bunny Alpha
The Space Bunny Alpha is an AI model offered by stealth that supports multiple input modalities, including text, image, and video. It has a high context length of 1 million characters, allowing for long and detailed processing. Additionally, it supports tools and reasoning capabilities. Considering its free price point, the Space Bunny Alpha may be worth shortlisting for those who need to process multimedia inputs or require advanced reasoning capabilities without incurring costs. However, as benchmark coverage is currently at zero, its performance relative to other models cannot be directly compared.
