Agent-World scales agent training by mining 1,978 real-world environments with 19,822 tools from the web. Using multi-environment reinforcement learning, Agent-World-8B achieves 61.8% on τ2-Bench and outperforms larger models across reasoning and coding benchmarks.
核心问题
How can we build scalable, realistic training environments for general-purpose agents and develop robust training methods for long-horizon, state-intensive tasks that require multi-tool orchestration and state tracking?
核心方法
{'approach': 'Agent-World unifies two components: (1) Agentic Environment-Task Discovery, which collects real-world themes, mines topic-aligned databases and executable tools from the web, and synthesizes verifiable tasks through graph-based and programmatic approaches; (2) Continuous Self-Evolving Agent Training, which uses multi-environment reinforcement learning (GRPO) with executable rewards and a diagnostic arena that identifies capability gaps to drive targeted environment expansion.', 'key_components': ['Agent-World unifies scalable environment-task discovery with continuous self-evolving agent training in a closed-loop system.', 'The Agentic Environment-Task Discovery component autonomously mines topic-aligned databases and executable tool interfaces from the web to form a realistic environment ecosystem.', 'The Continuous Self-Evolving Agent Training component uses multi-environment reinforcement learning with executable rewards for state-aware supervision.', 'The environment ecosystem serves as a dynamic diagnostic arena that identifies capability gaps and drives targeted environment-task expansion.', 'The two components enable co-evolution of agent policies and environments through iterative feedback.'], 'section_ids': ['sec_2']}

The paper fully specifies the Agent-World system with two tightly coupled components (Section 3.1 and 3.2) and provides extensive experimental validation across 23 benchmarks (Table 1, Figure 6). The system architecture is detailed, and its effective
The paper provides concrete statistics: 1,978 environments retained after filtering, 19,822 distinct tools (p_44, Figure 4). The methodology for environment-theme collection (p_11-p_14), database mining (p_15-p_18), and tool generation (p_19-p_25) is
The paper fully specifies the multi-environment RL training methodology (p_49-p_60) with executable rewards (p_56-p_58). Training results are demonstrated with GRPO curves (Figure 9) and benchmark improvements (Table 1).
The three sources are clearly specified (p_11-p_13), but the paper provides no justification for why these specific three sources were chosen, no comparison to alternative sources, and no ablation showing the contribution of each source. This is a de
The agentic workflow is specified (p_15-p_16) with policy model and toolset, but there's no justification for why this particular design was chosen over alternatives, no ablation comparing different toolsets, and no analysis of the workflow's effecti
The complexification process is described (p_17-p_18), but there's no ablation comparing different N values, no analysis showing that N rounds produces better databases than alternatives, and no quantitative evidence that this process improves qualit
The filtering criteria are clearly specified (p_21-p_24), but the specific thresholds (Acc > 0.5, at least one valid tool/test case) are not justified through ablation or comparison. Why 0.5 and not 0.6 or 0.4? The paper doesn't provide evidence for
Concrete quantitative evidence is provided in p_27 and Figure 3: 20 first-tier labels, 50 second-tier labels, and over 2K third-tier labels. The taxonomy construction methodology is also described.
The two synthesis strategies are described (p_28-p_42), but there's no ablation comparing graph-based vs programmatic approaches, no analysis of their relative contributions, and no justification for why these two specifically are optimal. The ration
The reverse-engineering paradigm is described (p_29), but there's no comparison to forward-generation approaches, no ablation showing this is better than alternatives, and no analysis of its advantages. The design choice is stated but not empirically
The three edge types with weights (3, 2, 1) are specified (p_30-p_33), but there's no justification for these specific weight values. Why 3, 2, 1 and not 4, 2, 1 or 3, 2, 0? No ablation or sensitivity analysis is provided.
The sandbox execution process is described (p_35), but there's no comparison to alternative refinement approaches, no ablation showing this improves task quality, and no quantitative analysis of the refinement's effectiveness.
The stability check (5 runs, ≥2 consistent) is specified (p_36), but there's no justification for these specific thresholds. Why 5 runs and not 3 or 10? Why ≥2 and not ≥3? No ablation or analysis is provided.
The difficulty scaling strategies are described (p_37), but there's no controlled ablation showing each strategy's individual contribution, no comparison of different scaling parameters, and the effectiveness is inferred from aggregate results rather
Concrete quantitative statistics are provided in p_44 and Figure 4: over 2,000 environments (1,978 retained), average >10 tools per environment, some with >40 tools, 19,822 distinct tools total. These are specific, measurable claims with supporting d
Concrete quantitative evidence in p_45 and Figure 4(e): all tasks have at least 7 interaction turns, average over 20 turns, some exceeding 40 turns. Specific numbers are provided.
Pass@10 evaluation results are reported in p_45 and Figure 4(f): only small fraction solved in all 10 attempts, most solved only once, some not solved at all. This provides quantitative evidence for difficulty scaling effectiveness.
The two reward types are specified (p_56-p_58), but there's no ablation comparing different reward designs, no analysis of their relative effectiveness, and no justification for why these specific reward mechanisms were chosen.
GRPO is adopted (p_59) with reference to prior work [84], but there's no comparison to other RL algorithms (PPO, DPO, etc.), no ablation showing GRPO's advantages for this specific setting, and the choice is justified only by citation rather than emp
K=5 environments per category is specified (p_62), but there's no justification for this specific value, no sensitivity analysis comparing different K values, and no analysis of coverage vs cost tradeoffs.

局限性(作者自述)
- From 500 to 2000 environments, the trend remains upward but the marginal improvement gradually decreases, indicating diminishing-yet-positive returns at larger scales.
- Second-round gains are smaller than first-round gains but remain positive, reflecting diminishing yet still effective returns.
