little m: an AI agent to formulate industrial process optimization models

Researchers released 'little m', an AI agent that combines a domain-specific knowledge repository with LLM-driven interaction to translate messy, multimodal industrial specifications (text and process diagrams) into mathematical optimization models. They also introduced IPC-Bench, a 50-scenario multimodal benchmark for industrial process control; evaluations (automated structural checks and double-blind human review) show little m generates substantially more semantically correct formulations than state-of-the-art LLMs, though the paper does not evaluate solver feasibility, physical validity, or closed-loop performance.

Paper proposes a confidence-gated hybrid (ensemble + LLM) for cost-effective emotion recognition in conversation

arXiv:2609.17977v1 compares a low-cost stacked ensemble, off-the-shelf LLM prompting (including GPT-4o-mini), and a confidence-gated hybrid that escalates low-confidence ensemble predictions to an LLM for dialogue-context emotion recognition. Across IEMOCAP, MELD, and CMU-MOSI the hybrid Pareto-dominates both pure systems (improving weighted F1 and cutting LLM spend by routing most turns to the near-zero-cost ensemble), with reported costs of roughly $10–85 vs $99–170 per million utterances for hybrid vs LLM-only pipelines.
