Formalizes the "same query, different results" problem via MDPs. Identifies three variance sources: information acquisition, compression, and inference. Achieves 22% stochasticity reduction while maintaining quality. Structured output formatting and ensemble queries are the most effective controls. (arXiv)

A new system gives simple queries a fast single-pass while triggering exploration and verification for complex joins. Achieves new SOTA on Spider and BIRD text-to-SQL benchmarks. Addresses a real production problem: uniform compute wastes money on easy queries and underperform...
Helium models agentic workloads as query plans with LLM invocations as first-class operators, adding proactive KV cache pre-warming for static prefixes and cost-based, cache-aware scheduling. Achieves 1.56x speedup over state-of-the-art agent serving systems with no model chan...
6-category threat taxonomy for web-scale agent ecosystems. Reviews 6 defense strategies. Identifies 4 critical open challenges including interoperable identity and ecosystem-level response coordination. arXiv 2603.01564 ---
Frames uncertainty as a first-class software engineering concern. Identifies propagation through agent coordination, data pipelines, human-in-the-loop, and runtime logic. Provides engineering patterns for safety-critical deployments — treats multi-agent reliability as systems...
arXiv 2609.13356, 227 HuggingFace upvotes, releases a 7B dense model trained from scratch on the premise that small models can't memorize the web but can trade parametric capacity for deliberate thinking plus external tools. Fully open recipe: interleaved gated sliding-window...
Diffusion LMs decode many tokens per step but pay to interact with all suffix tokens every step, and existing fixes just keep a local window while re-initializing suffix tokens identically each timestep (arXiv 2608.23167). This method splits the suffix into local, middle and t...
