The 3rd Perception Test challenge comprehensively evaluates the perception capabilities of large multimodal models using the Perception Test benchmark. This year, novel tracks unify diverse tasks under common interfaces: joint object/point tracking, joint action/sound localisation, and unified multiple-choice videoQA (integrating non-semantic tasks via inpainted queries). A new VLM interpretability track is included to investigate model strengths and failures. Guest tracks cover image understanding (KiVA) and video generation (Physics-IQ). Our workshop provides a venue to evaluate all foundation vision models—discriminative, generative, image- or video-based. Prizes up to 50k EUR are available.
