S1-M-7B-Beta used for developing the algorithm "Simple Test-time Scaling in Multimodal Reasoning". By fine-tuning the base model Qwen/Qwen2-VL-7B-Instruct on data with thinking tags <think> and </think>, the model acquired the think first, then response paradigm, allowing for experiments on "Test-time Scaling".
Note: The current model is a development version, not the final official version.
