TACO: Tool-Augmented Credit Optimization for Agentic Tool Use

cs.MA · 2026-06-29 · unverdicted · novelty 6.0

TACO combines Differential Answer-Probe Reward (DAPR) and Outcome-Gated Advantage Routing (OGAR) to assign credit to tool calls in agentic visual reasoning, producing accuracy gains on multimodal benchmarks.

Agent Explorative Policy Optimization for Multimodal Agentic Reasoning

cs.CL · 2026-05-27 · unverdicted · novelty 6.0

AXPO addresses the Thinking-Acting Gap in agentic RL training by targeted resampling of tool calls in all-wrong subgroups, delivering +1.8pp gains over GRPO on nine multimodal benchmarks with an 8B model beating a 32B baseline on Pass@4.
