New Benchmarks Target the Decision Agents Make Before They Answer
Two arXiv releases score the meta-decision of whether to answer, decompose, retrieve, execute code or delegate. A third replaces static persona prompts with synthesized lifelong memory.
Agentic systems spend most of their token budget on choices that precede the answer. MetaRoute-Bench formalizes exactly those choices, evaluating whether a controller should answer directly, decompose a task, call a tool, run code, delegate…

The Inference-Cost Efficiency Race
Techniques that cut tokens generated and KV-cache memory per query will keep compressing the marginal cost of serving reasoning models, making inference efficiency a recurring competitive axis alongside raw capability.
