Agentic SFT Dataset Overview

Updated 14 October 2025

Agentic SFT Dataset is a specialized fine-tuning corpus featuring multi-turn trajectories with explicit tool-use, internal reasoning, and identity maintenance.
It is constructed via automated workflows and manual curation to capture detailed stepwise actions, reflection, and error recovery in dynamic scenarios.
Its applications in autonomous decision-making, safety alignment, and multimodal interaction drive advances in robust and agentic AI systems.

An Agentic SFT Dataset is a specialized supervised fine-tuning dataset engineered to capture the multi-step interactions, tool-use events, reasoning processes, reflection, and identity-stabilizing features necessary for training LLMs and multimodal agents to exhibit robust agentic behaviors. Such datasets are distinguished from conventional single-turn or passive SFT corpora by their explicit inclusion of agentic trajectories: sequences of stepwise actions, internal reasoning, tool invocation, memory management, and outputs annotating intermediate decisions alongside final results. The development and use of Agentic SFT Datasets have been central to recent advances in agentic AI, autonomous reasoning systems, retrieval-augmented agents, and identity-consistent LLM scaffolding.

1. Conceptual Foundations and Defining Features

The Agentic SFT Dataset paradigm emerges as a response to the limitations of classic SFT, which typically exposes models to isolated input–output pairs without the context or reasoning steps inherent in true agentic workflows (Yu et al., 13 Oct 2025). Agentic SFT datasets are defined by several features:

Multi-turn, end-to-end trajectories: Each sample consists of full interaction histories—internal reasoning steps, pre-tool deliberation, tool invocation, error recovery, and self-calibration—rather than stitched or synthetic fragments (Yu et al., 13 Oct 2025).
Agentic behaviors: Trajectories are curated to showcase robust reasoning skills: information verification, authority evaluation, adaptive search, and error recovery (Jin et al., 8 Oct 2025).
Tool-use integration: Samples log not only reasoning but also explicit tool calls (e.g., code execution, web retrieval, database search), with detailed annotation of tool input, output, and agentic decisions (Shi et al., 11 Jun 2025, Shang et al., 28 Aug 2025).
Memory and identity management: Some datasets include mechanisms or probes for evaluating continuity, consistency, persistence, and recovery of agentic identity over long horizons (Perrier et al., 23 Jul 2025).
Reflective reasoning: Datasets sometimes record self-reflection, correction, and deliberation markers to support more strategic, less myopic agentic reasoning (Yao et al., 13 Oct 2025).

The intent is to create training corpora that allows SFT to initialize agentic models with adaptable, stable, multi-turn reasoning—serving as a foundation for reinforcement learning and other downstream alignment procedures.

2. Data Collection, Construction, and Structure

Agentic SFT Datasets are constructed via multiple strategies, depending on the targeted domain and agentic functions:

Automated workflow generation: Frameworks such as TaskCraft (Shi et al., 11 Jun 2025) synthesize testable atomic tasks involving tool use from unlabeled web, PDF, or image corpora. These atomic tasks are recursively extended via depth-based (multi-hop sequential steps) and width-based (subtask aggregation) strategies. Verification is performed using judge LLMs and rejection sampling to guarantee difficulty scaling and no leaking of answers.
Manual trajectory curation: Human annotators, domain experts, or strong teacher models generate multi-turn trajectories that go beyond the answer, logging intermediate thought processes, agentic decisions, and error corrections (Yu et al., 13 Oct 2025, Jin et al., 8 Oct 2025).
Embedded agentic events: Each sample is annotated with key event types: reasoning steps, tool invocations, memory updates, state changes, outputs, and, when relevant, agentic identity features.
Domain specialization: Examples span diverse application contexts, including query decomposition and chunk-aware retrieval over financial corpora (FinAgentBench (Choi et al., 7 Aug 2025)), safety policy reasoning (AIDSAFE (Kumarage et al., 27 May 2025)), adversarial red-teaming sequences (BAD-ACTS (Nöther et al., 22 Aug 2025)), and agentic information retrieval flows (Zhang et al., 13 Oct 2024).

Datasets are often hierarchical, with explicit trajectories (state $s_t$ , action $a_t$ , tool input/output, reasoning $r_t$ ) for each sample. Ground-truth verification steps and outcome signals are included to facilitate supervised learning and benchmarking.

3. Evaluation Metrics and Associated Benchmarks

Benchmark datasets and evaluation metrics have evolved to address both performance and agentic process fidelity:

Structural metrics: Node F1 Score and Structural Similarity Index (SSI) assess the faithfulness of agentic task decomposition graphs and transitions in autonomous multi-hop systems (Gabriel et al., 29 Oct 2024).
Tool-use metrics: Tool F1 Score computes precision and recall of correct tool invocation in both sequential and parallel task settings (Gabriel et al., 29 Oct 2024).
Reasoning quality: Pass@k, maj@k, average@k, and policy entropy are used to quantify the model’s exploration, test-time scaling, and accuracy in reasoning tasks (Jin et al., 8 Oct 2025, Yu et al., 13 Oct 2025).
Identity stability: Metrics formalized in LaTeX, such as the identifiability score $I(\Pi)$ and continuity score $C(\mathcal{A})$ , directly measure whether agentic models maintain identity under perturbation (Perrier et al., 23 Jul 2025).
Safety and adversarial robustness: Attack success rates, success/failure counts, and defense efficacy (e.g., via Guardian Agents) are provided for security-focused agentic data (Nöther et al., 22 Aug 2025).
IR and RAG performance: Standard IR metrics (nDCG, MAP, MRR) are used for datasets where agentic retrieval is validated separately at document and passage levels (Choi et al., 7 Aug 2025, Singh et al., 15 Jan 2025).

Comprehensive evaluation frameworks incorporate both outcome- and process-centered metrics, ensuring balanced performance measurement in real agentic workflows.

4. Agentic SFT in Model Training and Post-Training

Agentic SFT Datasets are leveraged for two primary training phases:

High-fidelity SFT initialization: Models first undergo supervised fine-tuning on agentic corpora, learning coordinated action selection, multi-step planning, tool-use heuristics, agentic identity maintenance, and reflection protocols. Key findings (Yu et al., 13 Oct 2025) show that SFT on real, end-to-end agentic trajectories yields stronger initialization, supporting higher exploration and eventual RL efficacy (compact models, e.g. 4B, can outperform previous 32B models given agentic data).
RL optimization and alignment: Agentic SFT is foundational for subsequent reinforcement learning, where agentic behaviors (rather than only outcome correctness) serve as strong inductive priors, resulting in efficient scaling and robust test-time exploration (Jin et al., 8 Oct 2025). RL recipes—such as GRPO styles with sequence- and token-level loss, higher clipping bounds, overlong reward shaping, and entropy maintenance—are optimized on top of agentic SFT (Yu et al., 13 Oct 2025, Shang et al., 28 Aug 2025).
Safety alignment and adversarial training: Policy-embedded reasoning chains, adversarial examples and belief augmentation are integrated into SFT (e.g., via AIDSAFE and BAD-ACTS) to fortify agents against jailbreaks, over-refusal, and adversarial manipulation (Kumarage et al., 27 May 2025, Nöther et al., 22 Aug 2025).

Performance is assessed across challenging agentic benchmarks (AIME2024/2025, GPQA-Diamond, LiveCodeBench-v6, GAIA, WebWalker, HLE), with agentic SFT frequently cited as providing the most substantial improvements in reasoning robustness and tool efficiency (Jin et al., 8 Oct 2025, Shi et al., 11 Jun 2025).

5. Agentic SFT for Multimodal and Specialized Domains

Surveyed datasets for Agentic Multimodal LLMs (MLLMs) (Yao et al., 13 Oct 2025) extend the agentic SFT paradigm into vision, video, audio, and interactive environments. Datasets are structured to support agentic internal intelligence (reasoning, reflection, memory), external tool invocation (search, code, visual ops), and environment interaction (GUI, navigation, manipulation). Examples include:

Vision reasoning and CoT: MAVIS (834K math visual samples), LLaVA-CoT-100K, Mulberry-260K (Monte Carlo Tree Search trajectories).
Code and search integration: MathCoder, ToRL, rStar-Coder (Shang et al., 28 Aug 2025), FVQA for multimodal search.
Environment interaction: GUI-World, VLA-IT for physical manipulation, VLN-Ego and InternData-N1 for navigation.

Agentic multimodal datasets and SFT extend the model’s ability to proactively plan, invoke tools, and adapt actions to dynamic environments.

6. Challenges, Best Practices, and Future Directions

Several key challenges and insights for Agentic SFT design and use are documented:

Data diversity and realism: Diverse, model-aware real agentic trajectories sustain exploration and more effective RL scaling (Yu et al., 13 Oct 2025). Synthetic, stitched trajectories lacking continuity and error correction yield weaker performance.
Annotation and scalability: Automated frameworks like TaskCraft and AsyncHow facilitate scalable generation and verification of agentic corpora across complexity levels (Shi et al., 11 Jun 2025, Gabriel et al., 29 Oct 2024).
Reasoning process vs. correctness: Recent work (Jin et al., 8 Oct 2025) demonstrates that SFT data capturing desirable reasoning behaviors outperforms data filtered for final correctness alone—a critical insight for data selection and training.
Identity stability: Embedding identity probes and recovery events during SFT prevents loss of agentic identity over long interactions and supports trustworthiness (Perrier et al., 23 Jul 2025).
Safety and adversarial robustness: Wide taxonomies of adversarial actions inform agentic SFT curation, ensuring robustness against coordinated attacks and manipulation (Nöther et al., 22 Aug 2025).
Regulatory and transparency requirements: Methods such as the Agentic Classification Tree (ACT) (Grari et al., 30 Sep 2025) allow agentic datasets to include explicit decision paths for compliance and auditability.

A plausible implication is that the agentic SFT paradigm will continue evolving to accommodate multi-agent, multi-tool, and multimodal settings; improving realism, identity stability, and safe behavior; and facilitating alignment and scaling of agentic systems.

7. Applications and Impact

Agentic SFT Datasets underpin advancements in agentic search, information retrieval, scientific reasoning, code execution, safety alignment, and multimodal interaction. Their integration is foundational to:

Autonomous decision-making agents in business, finance, healthcare, and scientific research (Zhang et al., 13 Oct 2024, Choi et al., 7 Aug 2025, Singh et al., 15 Jan 2025).
Interpretable and auditable AI systems for regulatory and ethical deployments (Grari et al., 30 Sep 2025).
Robust and general agentic systems that maintain effective reasoning, tool-use, and identity properties across dynamic, long-horizon environments (Yao et al., 13 Oct 2025, Zhang et al., 2 Sep 2025).

The curated, annotated, and scalable structure of agentic SFT datasets is central to the development of next-generation agents able to interact fluently with information, tools, and environments, thereby catalyzing progress across AI research and real-world deployment.
