Byte-Prefix Marginalization enables cross-tokenizer on-policy distillation between heterogeneous LLM families
A new arXiv preprint introduces Byte-Prefix Marginalization (BPM), a technique for distilling knowledge from teacher LLMs into a student model when the two use different tokenizers. BPM re-expresses the teacher's next-token distribution in a shared byte space, preserving probability mass and producing a vocabulary-complete alignment target. Evaluated with Qwen3-32B, GLM-Z1-9B-0414, and MiniMax-M2.7 as teachers, BPM improves six-benchmark average scores by 3.7–6.6 points over the strongest cross-tokenizer baselines on math and programming tasks. The method addresses a practical bottleneck in consolidating complementary open-weight models into compact students.
MedDDC-Eval: Diagnosis-Decoupled Evaluation Framework for Multi-Turn Medical Consultation Agents
Researchers introduce MedDDC-Eval, a benchmark framework that decouples history-elicitation quality from diagnosis generation in multi-turn medical consultation agents, using a shared frozen reader to hold the history-to-diagnosis mapping constant. The paper demonstrates that varying only the diagnostic reader shifts diagnosis F1 by 2.2–19.0 points and reverses 18–36% of pairwise policy orderings, exposing confounds in coupled evaluation. The authors also apply Group Relative Policy Optimization (GRPO) to post-train Qwen3-32B using diagnosis-result and trajectory feedback, achieving 9.7 and 4.6 total-score point improvements on two evaluation splits. The work addresses a methodological gap in evaluating medical dialogue agents by enabling controlled attribution of policy quality.
Program-as-Weights: compiling natural-language specs into compact neural adapters for local execution
Researchers introduce 'fuzzy-function programming' and its instantiation Program-as-Weights (PAW), a paradigm where a 4B compiler model converts natural-language function specifications into parameter-efficient adapters for a frozen lightweight interpreter. A 0.6B Qwen3 interpreter running PAW programs matches the performance of direct prompting with Qwen3-32B while using ~1/50th the inference memory and running at 30 tokens/s on a MacBook M3. The approach reframes large foundation models as one-time 'tool builders' rather than per-input solvers, targeting tasks like log triage, JSON repair, and intent-based ranking that resist rule-based implementation. The authors also release FuzzyBench, a 10M-example training dataset.
OpenThoughts-Agent: Open data curation pipeline for broadly capable agentic models
The OpenThoughts-Agent (OT-Agent) project releases a fully open data curation pipeline for training agentic language models, addressing the gap left by prior efforts (SWE-Smith, SERA, Nemotron-Terminal) that target single benchmarks. The team conducts over 100 controlled ablation experiments and assembles a 100K-example training set, fine-tuning Qwen3-32B to achieve 44.8% average accuracy across seven agentic benchmarks — a 3.9 percentage point improvement over the strongest existing open agentic model (Nemotron-Terminal-32B at 40.9%). Training data, pipeline, experimental data, and models are publicly released at openthoughts.ai.
HyperTool: Unified executable MCP-style interface reduces step-wise tool call overhead for LLM agents
HyperTool introduces a unified executable interface that allows LLM agents to invoke multiple tool calls within a single code block, hiding intermediate dataflow from the main reasoning trace. This addresses an 'execution-granularity mismatch' where step-wise atomic tool calls waste context and force models to manage low-level operations. On the MCP-Universe benchmark, HyperTool more than doubles accuracy for Qwen3-32B (15.69% → 35.29%) and Qwen3-8B (9.93% → 33.33%), outperforming GPT-OSS and Kimi-k2.5.
HiViG: History-aware visually grounded critic improves computer use agents across GUI benchmarks
Researchers introduce HiViG, a test-time framework for Computer Use Agents that addresses two weaknesses in existing critic models: short-sighted decision loops and lack of visual grounding. The system trains a multimodal critic on real GUI trajectories to maintain a compact macro-action history and verify execution coordinates against live screenshots before action execution. Evaluated on web, mobile, and desktop benchmarks, HiViG improves average success rates by 5.8% over the strongest baseline with Qwen3-VL-32B and 9.0% with Gemini-3-Flash, with both history and grounding components shown to be independently necessary.
Activation Capping Technique Stabilizes LLM Assistant Personas Against Drift and Jailbreaks
Researchers from MATS, Oxford, and Anthropic introduced the 'assistant axis,' a vector derived from LLM layer outputs that quantifies how closely a model adheres to its trained assistant persona. They developed 'activation capping,' an inference-time method that corrects deviations from this axis when similarity falls below a threshold. Testing on Gemma 2 27B, Qwen3 32B, and Llama 3.3 70B showed harmful response rates to jailbreak prompts dropped by roughly half (e.g., 83% to 41% for Qwen3 32B) without degrading benchmark performance. The technique targets character-based jailbreaks that bypass system prompts by manipulating a model's internal representational state.
