MMSearch-OPD is a new approach for long‑horizon multimodal search agents that combines a controllable data refinement pipeline with joint reinforcement learning and on‑policy distillation. The refinement process expands reasoning chains from existing simple multimodal questions, allowing adjustable search depth and cross‑modal evidence requirements while reusing image–question pairs. Training uses answer rewards, behavior penalties, and a decaying distillation coefficient to guide the agent, and experiments demonstrate that both data refinement and joint training after supervised fine‑tuning improve long‑horizon multimodal search performance.
AHEAD is a step‑aware framework that augments reinforcement learning for multi‑turn LLM agents by matching different supervision sources to different step types. The teacher receives environment feedback on all steps and LLM‑generated corrective hints only on error steps, providing finer‑grained guidance than uniform trajectory‑level rewards. Across ALFWorld, WebShop, and Search‑based QA, AHEAD improves task success by 13.3 points on ALFWorld and 11.0 on WebShop at 7B, reaches target success rates faster, and solves tasks within tighter interaction budgets compared to outcome‑only RL and prior self‑distillation baselines.

The study compares supervised fine-tuning (SFT) and reinforcement learning (RL) as teacher training methods for on-policy distillation (OPD) in a single-teacher setting. Using Qwen3.5-9B models across Agentic, Reasoning, and Perception domains, RL-trained teachers consistently produce stronger students and better recovery of performance gains than SFT-trained teachers. The authors attribute this advantage to RL teachers’ smaller parameter shifts from the shared initialization, which facilitates learning through OPD.
