The model generates responses to complex reasoning tasks-as demonstrated with GSM8K-by predicting sequences of tokens in chunks ranging from one to seven, achieving an average chunk size of 3.04 through a confidence-adaptive decoding strategy set at a 90% threshold.

A new training approach allows language models to generate text faster by learning to predict multiple tokens at once, without sacrificing quality.

The Art of the Deal: Can AI Agents Negotiate Like Humans?

08.02.2026 by qfx

AgenticPay establishes a negotiation framework wherein autonomous agents-acting as buyers and sellers-engage in diverse market structures, including one-to-one bargaining, one-to-many auctions, and complex many-to-many matching markets, ultimately facilitating multi-round dialogues driven by user-defined product requirements and culminating in finalized agreements.

New research introduces a challenging benchmark for evaluating artificial intelligence in complex buyer-seller scenarios, revealing crucial differences in negotiation abilities between leading AI models.

Beyond Domain Boundaries: Making Graph Neural Networks Truly Adaptable

08.02.2026 by qfx

EdgeMask-DG probes the limits of graph neural networks by iteratively pruning connections-augmenting the initial graph with [latex]kNN[/latex] and spectral edges, then pitting a network designed to sparsify those connections against one tasked with maintaining accuracy, ultimately revealing how robustly the system can perform under extreme structural stress.

A new framework, EdgeMask-DG*, enhances the ability of graph neural networks to generalize to unseen environments by focusing on core structural features.
