10.48550/arXiv.2603.26034A self-evaluation framework that dynamically coordinates LLM agents of varying capabilities to improve task efficiency and reasoning robustness.
Abstract
Autonomous agents powered by large language models (LLMs) perform complex tasks through long-horizon reasoning and tool interaction, where a fundamental trade-off arises between execution efficiency and reasoning robustness. Models at different capability-cost levels offer complementary advantages: lower-cost models enable fast execution but may struggle on difficult reasoning segments, while stronger models provide more robust reasoning at higher computational cost. We present AgentCollab, a self-driven collaborative inference framework that dynamically coordinates models with different reasoning capacities during agent execution. Instead of relying on external routing modules, the framework uses the agent's own self-reflection signal to determine whether the current reasoning trajectory is making meaningful progress, and escalates control to a stronger reasoning tier only when necessary. To further stabilize long-horizon execution, we introduce a difficulty-aware cumulative escalation strategy that allocates additional reasoning budget based on recent failure signals. In our experiments, we instantiate this framework using a two-level small-large model setting. Experiments on diverse multi-step agent benchmarks show that AgentCollab consistently improves the accuracy-efficiency Pareto frontier of LLM agents.

WHY NOW
LLM Agents moved forward this cycle; last verified April 2026. Public score 7.0/10. Production flags indicate code availability.
We present AgentCollab, a self-driven collaborative inference framework that dynamically coordinates models with different reasoning capacities during agent execution.
This is a core definition of the proposed framework, stated directly in the abstract.
partial
Instead of relying on external routing modules, the framework uses the agent's own self-reflection signal to determine whether the current reasoning trajectory is making meaningful progress, and escalates control to a stronger reasoning tier only when necessary.
This describes the self-evaluation mechanism central to the AgentCollab method, as stated in the abstract.
partial
To further stabilize long-horizon execution, we introduce a difficulty-aware cumulative escalation strategy that allocates additional reasoning budget based on recent failure signals.
This details a specific component of the AgentCollab method for stabilizing long-horizon execution, as described in the abstract.
partial
Experiments on diverse multi-step agent benchmarks show that AgentCollab consistently improves the accuracy-efficiency Pareto frontier of LLM agents.
This is a key experimental result reported in the abstract, summarizing the overall performance improvement.
partial
Similar trends are observed on HLE-math, where collaboration substantially improves reasoning accuracy (e.g., 8.0%→21.1% for DDV2) while still preserving clear speedup over the large-model baseline.
This provides specific quantitative results for a benchmark, demonstrating the accuracy improvement and efficiency preservation.
partial
Closed-source models such as GPT or Gemini are not included in the experiments because their API-based latency is less stable and difficult to control, which would introduce confounding factors when evaluating efficiency.
This explains a technical decision made in the experimental setup and the reasoning behind it.
partial
the middle system reaches nearly the same breadth and accuracy through collaboration
This is an interpretation of the experimental results presented in the analysis section, comparing AgentCollab to a large-model baseline.
