• [2026/08/05] We release Video-DeepResearch paper! Video-DR extends Vision-DR to continuous video streams. Code lives under Video-DeepResearch/.

• [2026/06/08] We released Vision-DeepResearch-30B-A3B.

• [2026/05/24] We have released the subset of our used benchmark subset and detailed evaluation guidance! Please see VQA Benchmark Subset and Eval Guidance.

• [2026/05/01] Vision-DeepResearch has been accepted by ICML 2026! Nice to see you at the conference!

• [2026/02/03] We released SFT code, RL code! We will finish the guidance later, stay tune!

• [2026/02/02] We released Cold-start Dataset (demo), RL Dataset (demo), Vision-DeepResearch-8B (SFT-only), VDR-Bench (full), VDR-Bench (testmini)!

Download the Cold-start dataset (Demo 1K).

You need to convert the data in Parquet format into the JSONL training format supported by ms-swift. We provide a conversion script for this purpose: ms-swift/run/data_prepare/convert_parquet2jsonl.sh.

You need to provide an --image_dir, where images stored as bytes in the Parquet file will be converted to .png/.jpg files and saved to disk.

Download the RL dataset (Demo 1K).

First, you need to convert the data in Parquet format into the JSONL format. We provide a conversion script for this purpose: rllm/vision_deepresearch_async_workflow/data_prepare/convert_parquet2jsonl.sh.

Then, you need to run rllm/vision_deepresearch_async_workflow/data_prepare/register_rl_dataset.sh to register the RL dataset.

cd ms-swift
bash run/vision_deepresearch_SFT_30B_A3B_megatron_lr2e5_2ep.sh

First, deploy the Extract model (used to summarize web page contents) and the Judge model:

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 vllm serve \
 Qwen/Qwen3-VL-30B-A3B-Instruct \
  --host 0.0.0.0 \
  --port 8001 \
  --tensor-parallel-size 8 \
  --gpu-memory-utilization 0.8 \
  --served-model-name "Qwen3-VL-30B-A3B-Instruct" \
  --max_model_len 160000 \
  --mm-processor-cache-gb 0 \
  --no-enable-prefix-caching

Then, modify the vLLM URL service endpoints for JUDGE_MODEL and EXTRACT_MODEL in rllm/.env, and enter your SERP_API_KEY, JINA_API_KEY, and OSS configuration.

Run RL train.

cd rllm
bash vision_deepresearch_async_workflow/run/vision_deepresearch_30B_A3B_grpo_plus_bfloat16_sglang_megatron_128batch_128mini_8n.sh

Run the command below to start an OpenAI-compatible API service:

Vision-DeepResearch model:

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 vllm serve \
 Osilly/Vision-DeepResearch-8B \
  --host 0.0.0.0 \
  --port 8001 \
  --tensor-parallel-size 8 \
  --gpu-memory-utilization 0.8 \
  --served-model-name "Vision-DeepResearch-8B" \
  --max_model_len 160000 \
  --mm-processor-cache-gb 0 \
  --no-enable-prefix-caching

Extract model (used to summarize web page contents) and Judge model:

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 vllm serve \
 Qwen/Qwen3-VL-30B-A3B-Instruct \
  --host 0.0.0.0 \
  --port 8001 \
  --tensor-parallel-size 8 \
  --gpu-memory-utilization 0.8 \
  --served-model-name "Qwen3-VL-30B-A3B-Instruct" \
  --max_model_len 160000 \
  --mm-processor-cache-gb 0 \
  --no-enable-prefix-caching

Modify the vLLM URL service endpoints for JUDGE_MODEL and EXTRACT_MODEL in rllm/.env, and enter your SERP_API_KEY, JINA_API_KEY, and OSS configuration.

Modify the base-url and model (the Vision DeepResearch vLLM service endpoint and model name) in rllm/eval/run_eval.sh. For the data format of test.parquet, refer to rllm/eval/README.md.

Run rllm/eval/run_eval.sh to start inference.

bash rllm/eval/run_eval.sh
