PASK: Toward Intent-Aware Proactive Agents with Long-Term Memory
Pith reviewed 2026-05-10 18:01 UTC · model grok-4.3
The pith
A streaming model for demand detection combined with hybrid long-term memory lets proactive agents infer latent user needs and intervene under real-time constraints.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The authors argue that a closed-loop proactive system becomes feasible once demand detection runs in a streaming fashion, memory is maintained as a hybrid of workspace, user-specific, and global stores, and the three elements feed one another continuously. In their Pask instantiation, the IntentFlow model performs demand detection while the memory component grounds longer-horizon actions, and the overall loop is evaluated on LatentNeeds-Bench, a dataset constructed from real consented interactions and refined by thousands of human edits. Under this setup the detection model matches the speed of leading fast language models while identifying more latent needs.
What carries the argument
The DD-MM-PAS paradigm, a three-part structure in which streaming demand detection infers latent needs, hybrid memory maintains context across time scales, and the proactive agent system executes grounded interventions in a closed loop.
If this is right
- Agents built this way can maintain continuous awareness of user context without requiring explicit commands at every step.
- Hybrid memory stores allow actions to be conditioned on both short-term workspace state and longer-term user patterns.
- The closed loop supports ongoing refinement because detected needs and executed actions update the memory stores in turn.
- The same paradigm can be re-instantiated with different detection models or memory back-ends while preserving the overall flow.
Where Pith is reading between the lines
- If the approach scales, personal assistants could shift from responding to stated requests toward preempting routine friction points in daily workflows.
- The memory modeling component could be extended to handle shared or multi-user contexts where needs are distributed across participants.
- Because the benchmark emphasizes real-time constraints, the design implies that similar systems could be embedded in always-on devices without draining resources.
Load-bearing premise
The benchmark built from user-consented data and repeated human editing is representative enough of real-world depth, ambiguity, and timing pressures to confirm that the closed-loop system works outside the lab.
What would settle it
Deployment logs from the system running live with actual users showing either higher latency than reactive baselines or no measurable improvement in anticipating needs that users later confirm as relevant.
read the original abstract
Proactivity is a core expectation for AGI. Prior work remains largely confined to laboratory settings, leaving a clear gap in real-world proactive agent: depth, complexity, ambiguity, precision and real-time constraints. We study this setting, where useful intervention requires inferring latent needs from ongoing context and grounding actions in evolving user memory under latency and long-horizon constraints. We first propose DD-MM-PAS (Demand Detection, Memory Modeling, Proactive Agent System) as a general paradigm for streaming proactive AI agent. We instantiate this paradigm in Pask, with streaming IntentFlow model for DD, a hybrid memory (workspace, user, global) for long-term MM, PAS infra framework and introduce how these components form a closed loop. We also introduce LatentNeeds-Bench, a real-world benchmark built from user-consented data and refined through thousands of rounds of human editing. Experiments show that IntentFlow matches leading Gemini3-Flash models under latency constraints, while identifying deeper user intent.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes the DD-MM-PAS paradigm (Demand Detection, Memory Modeling, Proactive Agent System) for streaming proactive AI agents that infer latent needs from context and ground actions in long-term user memory under latency and long-horizon constraints. It instantiates the paradigm in the PASK system using the IntentFlow model for demand detection, a hybrid memory architecture (workspace, user, global), and PAS infrastructure to form a closed loop. The work also introduces LatentNeeds-Bench, a benchmark constructed from user-consented data refined via thousands of rounds of human editing, and reports that IntentFlow matches leading Gemini-3-Flash models under latency constraints while identifying deeper user intent.
Significance. If the experimental claims are substantiated with full methodology and end-to-end metrics, the work could meaningfully advance proactive agents beyond laboratory settings by addressing real-world requirements for depth, ambiguity, precision, and real-time performance through intent-aware systems with persistent memory. The introduction of a general paradigm and a real-world benchmark represents a constructive contribution, though the current manuscript provides limited verifiable evidence for these advances.
major comments (3)
- [Experiments] The experimental evaluation section provides no methodology details, baselines, metrics (e.g., exact latency thresholds, accuracy or F1 scores), error analysis, or data splits to support the claim that IntentFlow matches Gemini-3-Flash models under latency constraints while identifying deeper intent. This absence makes it impossible to assess or reproduce the reported performance.
- [LatentNeeds-Bench] The LatentNeeds-Bench description lacks any disclosure of task distribution, inter-annotator agreement statistics, or concrete test cases exercising workspace/user/global memory retrieval under streaming real-time constraints. Without these, it is unclear whether the benchmark validates the closed-loop DD-MM-PAS claims.
- [Closed-loop system] No end-to-end metrics for the full closed-loop system—such as intervention precision, memory-retrieval accuracy over multi-hour sessions, or user-level success rates—are reported. The central claim that IntentFlow + hybrid memory + PAS infrastructure handles streaming latent-need inference therefore rests on an untested assumption.
minor comments (1)
- [Abstract] The abstract refers to 'Gemini3-Flash' without specifying the exact model version or release; this should be clarified for reproducibility.
Simulated Author's Rebuttal
Thank you for the thorough and constructive review. We appreciate the identification of areas where additional detail is required to substantiate the claims. We will revise the manuscript to include expanded experimental methodology, benchmark statistics, and available end-to-end metrics. Point-by-point responses follow.

Referee: [Experiments] The experimental evaluation section provides no methodology details, baselines, metrics (e.g., exact latency thresholds, accuracy or F1 scores), error analysis, or data splits to support the claim that IntentFlow matches Gemini-3-Flash models under latency constraints while identifying deeper intent. This absence makes it impossible to assess or reproduce the reported performance.
Authors: We agree that the experimental section requires substantially more detail for reproducibility. In the revised manuscript we will add the full methodology, including the exact latency thresholds applied, accuracy and F1 scores for IntentFlow versus Gemini-3-Flash, the complete set of baselines, error analysis, and the train/validation/test splits used. These additions will directly support the reported performance claims. revision: yes

Referee: [LatentNeeds-Bench] The LatentNeeds-Bench description lacks any disclosure of task distribution, inter-annotator agreement statistics, or concrete test cases exercising workspace/user/global memory retrieval under streaming real-time constraints. Without these, it is unclear whether the benchmark validates the closed-loop DD-MM-PAS claims.
Authors: We acknowledge the need for greater transparency on the benchmark. The revision will include task distribution statistics, inter-annotator agreement figures from the multi-round human editing process, and concrete test-case examples that exercise workspace, user, and global memory retrieval under streaming constraints. This will clarify how the benchmark supports the DD-MM-PAS paradigm. revision: yes
-
Referee: [Closed-loop system] No end-to-end metrics for the full closed-loop system—such as intervention precision, memory-retrieval accuracy over multi-hour sessions, or user-level success rates—are reported. The central claim that IntentFlow + hybrid memory + PAS infrastructure handles streaming latent-need inference therefore rests on an untested assumption.
Authors: The current manuscript emphasizes component-level results and the benchmark; however, we recognize that end-to-end evaluation is essential. In the revision we will report all available end-to-end metrics (intervention precision and memory-retrieval accuracy) from the benchmark runs. For multi-hour session metrics we will add a discussion of current limitations and any preliminary aggregated results we can provide, while noting that full user-level longitudinal studies remain future work. These additions will strengthen the support for the closed-loop claims. revision: partial
Circularity Check
No significant circularity; claims rest on empirical description without self-referential reduction
full rationale
The paper introduces the DD-MM-PAS paradigm and its Pask instantiation as a descriptive framework for proactive agents, along with the LatentNeeds-Bench constructed from user data and human editing. No equations, derivations, fitted parameters, or mathematical predictions appear in the abstract or described components. Experimental claims (IntentFlow matching Gemini-3-Flash under latency while identifying deeper intent) are presented as direct results rather than reductions to prior inputs by construction. No self-citations, uniqueness theorems, or ansatzes are invoked as load-bearing steps in the provided text. The derivation chain is therefore self-contained and non-circular, with central claims depending on external benchmark validation instead of internal redefinition.
