Streaming video models must notice instructions given visually, such as a hand wave, and respond in seven subtasks of visual instruction feedback.

Released with the ViSpeak-Instruct training set and the ViSpeak model. The scoring field is a guess.

In the authors’ words

Recent advances in Large Multi-modal Models (LMMs) are primarily focused on offline video understanding. Instead, streaming video understanding poses great challenges to recent models due to its time-sensitive, omni-modal and interactive characteristics. In this work, we aim to extend the streaming video understanding from a new perspective and propose a novel task named Visual Instruction Feedback in which models should be aware of visual contents and learn to extract instructions from them. For example, when users wave their hands to agents, agents should recognize the gesture and start conversations with welcome information. Thus, following instructions in visual modality greatly enhances user-agent interactions. To facilitate research, we define seven key subtasks highly relevant to visual modality and collect the ViSpeak-Instruct dataset for training and the ViSpeak-Bench for evaluation. Further, we propose the ViSpeak model, which is a SOTA streaming video understanding LMM with GPT-4o-level performance on various streaming video understanding benchmarks. After finetuning on our ViSpeak-Instruct dataset, ViSpeak is equipped with basic visual instruction feedback ability, serving as a solid baseline for future research.

Seed2.0 Lite (0428) leads with 87% among models released by April 2026

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in April 2026, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 Seed2.0 Lite (0428) 87%
  2. 2 Seed1.8 79%
  3. 3 Seed2.0 Pro 78.5%

2 models have held number one in labs’ own numbers since its release in March 2025

Lab claims count from the day the card came out, independent runs from the model’s release.

ByteDance Seed’s own number for Seed2.0 Lite (0428) passed 85% in April 2026

All the scores we have, one dot each, so a model tested at several settings appears more than once.
