Model
EventMemAgent uses a Qwen3-VL-8B-Instruct policy with hierarchical event-centric
memory and adaptive memory-retrieval, OCR and object-detection tools. Event
captions are generated separately by a frozen Qwen3-VL-4B-Instruct model;
event/query embeddings use Qwen3-Embedding-0.6B.
This upload contains the merged actor from training run 1-30_8B, step 150,
in standard Hugging Face format. It includes the model, tokenizer, processor and
chat template. Optimizer states, training logs and evaluation predictions are
not included.
Training
10K MovieChat samples annotated by VideoMarathon; multi-turn GRPO with group
size 8, global batch 64, PPO minibatch 32 and per-GPU microbatch 1. AdamW uses
a learning rate of 1e-6, five warmup steps, one epoch and no KL loss. Training
prompt/response limits are 8192 tokens each, with at most ten assistant turns.
Usage
Download the checkpoint and configure MODEL_PATH in the accompanying code:
hf download lingcco/EventMemAgent-8B --local-dir checkpoints/released/EventMemAgent-8B
Use the code repository's inference and evaluation entry points. The checkpoint
alone does not implement streaming memory or provide OCR and detection services;
these are separate components of the pipeline.

License and limitations
The model is released under Apache 2.0, following its Qwen3-VL-8B-Instruct
base model. The research model can
produce incorrect answers; memory captions and perception tools can also make
errors. It is not intended for safety-critical use.
