Scaling Past Informal AI - Carina Hong, Axiom Math

Axiom Math's $200M Series A signals a strategic pivot in AI scaling: formal verification through theorem provers like Lean as the foundation for mathematical reasoning, not a downstream patch. The startup's perfect Putnam score positions verified generation as superior training signal compared to informal reinforcement learning, challenging the assumption that scale alone drives capability. This reflects growing conviction among frontier builders that mathematical AGI requires provable correctness baked into the learning loop from inception, reshaping how the field thinks about reliability and compounding intelligence.

STRIDE: Training Data Attribution via Sparse Recovery from Subset Perturbations

STRIDE addresses a fundamental bottleneck in training data attribution for LLMs by shifting from parameter-space gradient tracking to activation-space modeling. Rather than repeatedly retraining models to measure causal influence, the framework uses sparse recovery to estimate how training examples shape model outputs. This matters because attribution remains critical for auditing, debugging, and defending against data poisoning, yet existing methods don't scale to billion-parameter models. The activation-space approach sidesteps both computational expense and the brittleness of local approximations, potentially unlocking interpretability at production scale.

Beyond Text Following: Repairable Arbitration Reversals in Audio-Language Models

Researchers have identified a critical failure mode in audio-language models: when text and audio conflict, these systems systematically prefer text despite clear audio evidence. Using counterfactual analysis across five ALMs, the team found that 64% of conflict cases flip their preference when conflicting text is removed, indicating the audio signal is encoded but loses an internal arbitration process. Activation patching traces this reversal to answer-generation layers. This finding exposes a fundamental alignment problem in multimodal systems and suggests that training procedures may inadvertently teach models to weight text over sensory input, with implications for reliability in real-world deployment.

Streaming Communication in Multi-Agent Reasoning

StreamMA challenges the conventional serial pipeline in multi-agent reasoning by enabling agents to consume partial outputs from upstream peers in real time rather than waiting for complete chains. This architectural shift cuts latency linearly with system depth while paradoxically boosting accuracy, since early reasoning steps are more reliable than later ones and can guide downstream agents without contamination from error-prone tail reasoning. The work formalizes a tradeoff space between throughput and quality that reshapes how production multi-agent systems should be designed, particularly for latency-sensitive applications where reasoning depth currently forces unacceptable delays.

Reinforcement Learning from Rich Feedback with Distributional DAgger

Researchers propose distributional DAgger, a refinement to reinforcement learning that leverages rich feedback signals beyond binary correctness labels. Rather than the standard practice of sampling many outputs and scoring only pass/fail, this approach incorporates execution traces, tool outputs, expert corrections, and model self-assessments to guide learning. The method uses a cross-entropy objective that enables fine-grained credit assignment across reasoning steps, addressing a fundamental limitation in current reasoning model training. This work matters because it expands the feedback surface available to RL systems, potentially improving sample efficiency and reasoning quality in domains where detailed intermediate signals exist.

Failed Reasoning Traces Tell You What Is Fixable (But Not by Reading Them)

Researchers propose a method to distinguish between recoverable and structural failures in language model reasoning by analyzing the statistical signature of failed rollouts rather than their content. The work challenges the assumption that test-time compute scaling uniformly improves performance, suggesting instead that failure modes cluster into predictable regimes where specific interventions succeed or fail. This distinction matters for practitioners optimizing inference budgets: identifying which failures respond to resampling versus requiring architectural or training changes could reshape how teams allocate compute during deployment.

Activation-Based Active Learning for In-Context Learning: Challenges and Insights

Researchers conducted the most extensive empirical study to date on using transformer activation patterns to improve in-context example selection for LLMs, testing across multiple model architectures and datasets. The work challenges a prevailing assumption in the field: MLP activations and statistical moments derived from them fail to predict which examples will actually improve model performance. This negative result matters because it redirects effort away from activation-based signals toward alternative selection mechanisms, and surfaces a gap between our theoretical understanding of transformer internals and their practical utility for prompt optimization.

Self-Evaluation Is Already There: Eliciting Latent Judge Calibration in Base LLMs with Minimal Data

Researchers demonstrate that base language models possess an underutilized capacity to assess their own output quality against external evaluators, requiring only few-shot prompting to activate. Self-Evaluation Elicitation (SEE) combines calibration-aware reinforcement learning with masked distillation to sharpen this latent ability using 160 examples, achieving results comparable to standard RL approaches at roughly 31x lower data cost. This finding reshapes how the field thinks about model self-awareness and evaluation efficiency, with direct implications for scaling judge-based training pipelines and reducing the annotation burden in iterative model improvement workflows.

Audio Interaction Model

Researchers have unified streaming audio models into a single always-on system that listens, decides, and responds in real time, moving beyond today's task-specific audio language models. Audio-Interaction combines offline capability retention with online instruction following across dialogue and voice chat, using a new SoundFlow framework to manage the perceive-decide-respond loop. This shift toward unified, interactive audio agents represents a meaningful step in multimodal AI, particularly for applications requiring continuous environmental awareness and semantic-driven response timing rather than fixed task pipelines.

Continual Visual and Verbal Learning Through a Child's Egocentric Input

Researchers have built BabyCL, a continual learning system that mirrors how children actually acquire language by processing egocentric video in a single chronological pass rather than shuffling data across hundreds of epochs. The framework combines streaming visual representation learning with image-text contrastive objectives using temporal segmentation and dual replay buffers, trained on the SAYCam dataset. This work challenges a core assumption in multimodal AI: that order-agnostic batch training is necessary for learning word-referent mappings. The shift toward temporally coherent, single-pass learning could reshape how foundation models ingest and integrate visual and linguistic signals, particularly for embodied AI systems.

Evaluating Large Language Models in Dynamic Clinical Decision-Making with Standardized Patient Cases

Researchers have built MedSP1000, an interactive benchmark that moves clinical LLM evaluation beyond static Q&A into dynamic, multi-turn scenarios modeled on medical education's standardized patient methodology. The dataset contains 1,638 cases with nearly 25,000 peer-reviewed rubrics, enabling assessment of how models gather information, adapt treatment plans, and manage longitudinal care across evolving patient states. This addresses a critical gap in clinical AI validation: existing benchmarks cannot measure whether LLMs behave like competent clinicians in realistic, sequential decision-making. The work signals growing rigor in healthcare AI evaluation and raises the bar for claims about clinical readiness.

Arithmetic Pedagogy for Language Models

Researchers demonstrate that pedagogical frameworks from human mathematics instruction can systematize arithmetic reasoning in language models. By encoding the GASING method, an Indonesian left-to-right arithmetic procedure, into chain-of-thought supervision and training a small GPT-2 model from scratch without reinforcement learning, the work reveals distinct learning phases and mechanistic patterns. This bridges cognitive science and model training, suggesting that aligning inductive biases with human problem-solving structures may improve reasoning capabilities in resource-constrained settings, with implications for how we design supervision signals beyond standard next-token objectives.

Light or Full Verb? A Minimal-Pair Dataset for Probing Phraseological Competence in Language Models

Researchers have created a controlled dataset to test whether language models actually grasp the semantic distinction between light verbs (make a decision) and full predicates (make a cake). The work reveals that LLMs do encode this phraseological nuance even in minimal contexts, with separable activation patterns tied to object type. This matters for interpretability: it suggests models capture linguistic structure beyond surface statistics, and the released dataset and framework enable systematic probing of how well models handle compositional meaning across languages and verb classes.

Automatic Generation of Titles for Research Papers Using Language Models

Researchers have developed a pipeline for automated academic title generation by fine-tuning language models on paper abstracts, introducing a new social-science dataset and benchmarking against GPT-3.5-turbo across multiple semantic metrics. The work signals growing interest in automating scholarly metadata tasks, where title quality directly affects discoverability and citation patterns. Fine-tuned PEGASUS outperformed larger closed models, suggesting that domain-specific adaptation remains competitive with frontier LLMs on narrow, high-value tasks. This matters for publishing infrastructure and author tooling, where title generation could reduce friction in manuscript submission workflows.

Fast & Faithful Function Vectors

Researchers have refined function vectors, a technique for steering LLM behavior during in-context learning, by optimizing two critical design choices. Using gradient-based attribution methods to select attention heads improves both computational efficiency and accuracy, while distributing steering signals across multiple layers outperforms naive aggregation. The work addresses a gap in how these task representations are actually constructed, offering practitioners concrete improvements for controllable LLM inference. Public code release amplifies adoption potential among teams building interpretable or steerable systems.

Boosting Self-Consistency with Ranking

Majority voting in self-consistency decoding leaves performance on the table by ignoring correct answers buried in sample distributions. Ranking-Improved Self-Consistency (RISC) reframes answer selection as a learned ranking task, using LambdaRank to weight candidates across frequency, semantic similarity, and reasoning consistency rather than simple vote counts. The technique improves accuracy-efficiency trade-offs across multiple benchmarks, addressing a concrete bottleneck in test-time scaling that affects any deployment relying on sampling-based reasoning verification.

In-Context Graphical Inference

Researchers propose In-Context Graphical Inference, a Graph Transformer that bridges exact and approximate inference in discrete graphical models by embedding variable elimination into an autoregressive architecture. The approach uses learned Tensor-Train compression and conformal prediction to deliver both convergence guarantees and scalability, addressing a fundamental tension in probabilistic inference that has constrained real-world deployment of graphical models. This work signals growing interest in using transformer inductive biases to solve classical inference problems, potentially unlocking graphical models for larger-scale applications where iterative methods currently fail.

Imbuing Large Language Models with Bidirectional Logic for Robust Chain Repair

Researchers propose Teleological Reasoning Infilling, a training method that retrofits decoder-only transformers with bidirectional reasoning capabilities to repair broken chain-of-thought chains. Rather than accepting error propagation as inherent to autoregressive generation, the framework reframes corrupted reasoning segments as fill-in-the-middle tasks, allowing models to synthesize logical bridges between verified premises and downstream milestones. This addresses a fundamental architectural limitation in current LLMs and could reshape how reasoning robustness is engineered into production systems.

Validity Threats for Foundation Model Research

Foundation model research faces a methodological crisis as compute constraints force researchers away from rigorous controlled experiments toward cheaper proxies like scaling laws and single-run designs. This arXiv paper catalogs the hidden validity threats embedded in these shortcuts, arguing that computational savings introduce untestable assumptions that can silently undermine research claims. For the field, this signals a growing credibility gap: as models scale beyond experimental feasibility, the empirical foundations supporting capability claims and architectural decisions become increasingly fragile. Insiders should expect heightened scrutiny of published results and pressure to develop new validation frameworks.

TaDA: Calibrated Probe Gating for Task-Domain LoRA Merging

Researchers have identified a structural asymmetry in how task and domain LoRA adapters behave across transformer layers, with domain knowledge concentrating deeper while task signals remain stronger in shallow layers. TaDA exploits this finding through layer-wise gating and subspace-aware merging to unify dual adapters without retraining. This addresses a practical bottleneck in multi-adapter deployment, where naive symmetric merging degrades performance. The work matters for practitioners scaling fine-tuned models across multiple objectives simultaneously, reducing inference overhead while preserving task-domain separation benefits.

Depth-Attention: Cross-Layer Value Mixing for Language Models

Depth-Attention proposes a structural fix to how Transformers reuse information across layers. Current models add each layer's output to a residual stream without selective cross-layer retrieval, forcing later layers to work with whatever earlier layers contributed. This paper embeds cross-layer value selection directly into the attention mechanism, letting queries at each layer attend to and mix key-value pairs from prior layers at matching token positions. The approach avoids the inference-time memory overhead that plagues existing cross-layer methods, a constraint that sharpens as production LLMs adopt aggressive cache compression via grouped-query and multi-head latent attention. For practitioners optimizing inference cost and model depth, this signals a path to richer layer interaction without sacrificing throughput.

DAR: Deontic Reasoning with Agentic Harnesses

Researchers propose Deontic Agentic Reasoning (DAR), a framework that lets language models dynamically retrieve relevant rules and statutes during inference rather than processing entire rulesets upfront. This addresses a critical bottleneck in high-stakes domains like tax computation and immigration law, where cross-referenced policies exceed context windows and models frequently miss applicable rules. Testing on DeonticBench reveals agentic retrieval improves performance on hard cases, though gains vary by model scale, suggesting that weaker models may struggle with the added complexity of agent-based lookup. The work signals growing focus on making LLMs reliable for compliance and legal reasoning through architectural innovation rather than scale alone.

M$^3$Eval: Multi-Modal Memory Evaluation through Cognitively-Grounded Video Tasks

Researchers have released M3Eval, a cognitive-psychology-informed benchmark designed to measure how well multimodal models retain and recall information across long-form video. Unlike existing video datasets that emphasize perception and reasoning, this framework isolates memory fidelity, interference resistance, and information preservation. Early experiments across representative models expose consistent gaps in how faithfully these systems maintain context over extended sequences. The work signals a maturation in video-understanding evaluation beyond surface-level task performance, addressing a blind spot as the field pushes toward production-grade long-context reasoning.

GARL: Game-Theoretic Reinforcement Learning for Multi-Agent Strategic Prioritisation

Researchers propose GARL, a game-theoretic reinforcement learning framework that treats multi-agent LLM coordination as a structured two-stage game where competing agents allocate resources before a final arbiter ranks outcomes. This addresses a critical gap in multi-agent RL: most reward functions remain ad-hoc and disconnected from the underlying interaction dynamics. By grounding agent incentives in formal game theory rather than task-specific heuristics, GARL offers a more principled path to scaling collaborative LLM systems for strategic decision-making, with implications for enterprise deployments where agent alignment and resource contention are live problems.

DeliChess: A Multi-party Dialogue Dataset for Deliberation in Chess Puzzle Solving

DeliChess introduces a structured dataset for studying how groups reason through complex problems via dialogue, using chess puzzles as a controlled testbed. The work demonstrates that multi-party deliberation measurably improves collective decision-making accuracy, offering researchers a rare resource for training and evaluating collaborative reasoning in language models. This addresses a gap in AI evaluation: most benchmarks measure individual performance, not the dynamics of group problem-solving that increasingly matters as AI systems are deployed in team settings.

Probing Outcome-Level Resemblance and Mechanism-Level Alignment in LLM Risk Decisions: Evidence from the St. Petersburg Game

Researchers tested 28 LLMs on the St. Petersburg paradox, a classical economics puzzle where rational expected value diverges sharply from human behavior. The study reveals a critical gap in AI alignment: models that produce cautious-looking outputs may not actually replicate human decision-making logic. By systematically varying game parameters, prompt framing, and comparing base models to instruction-tuned variants, the work exposes whether LLM risk aversion stems from genuine mechanism alignment or surface-level mimicry. This matters for deployment in high-stakes domains where appearing aligned masks fundamentally different reasoning.

SAID: Accelerating Diffusion-Based Language Models via Scaffold-Aware Iterative Decoding

Diffusion-based language models promise parallel token generation but suffer from expensive inference due to repeated denoising cycles. SAID addresses this by prioritizing computation on high-impact scaffold tokens that establish semantic structure, then rushing through predictable detail tokens with minimal steps. A companion technique, Confidence-Hierarchical Layered Generation, further optimizes by allocating extra denoising only to uncertain positions. This work matters because it directly tackles the inference efficiency bottleneck that has limited DLLM adoption relative to autoregressive models, potentially reshaping the cost-performance tradeoff in non-autoregressive generation.

SemBlock: Semantic Boundary Dynamic Blocks for Diffusion LLMs

Diffusion language models face a practical bottleneck in token generation speed, and existing blockwise decoding strategies rely on crude heuristics like fixed sizes or delimiter signals that ignore linguistic structure. SemBlock reframes the problem as semantic boundary prediction, training lightweight classifiers to identify natural commit points in discourse, reasoning, and code spans. This work matters because it bridges a gap between theoretical diffusion-based generation and deployment efficiency, potentially unlocking faster inference for an emerging class of models that compete with autoregressive architectures on quality while offering different parallelization tradeoffs.
