Model overview
TRIBE v2 is a deep multimodal brain encoding model that predicts fMRI brain responses to naturalistic stimuli (video, audio, text). It combines state-of-the-art feature extractors — **LLaMA 3.2** (text), **V-JEPA2** (video), and **Wav2Vec-BERT** (audio) — into a unified Transformer architecture that maps multimodal representations onto the cortical surface. Predictions are for the "average" subject (see paper for details) and live on the **fsaverage5** cortical mesh (~20k vertices). You can also pass `text_path` or `audio_path` to `model.get_events_dataframe` — text is automatically converted to speech and transcribed to obtain word-level timings.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
