- Best-of-N spends the same verification compute on easy and hard candidates alike.
- Generative verifiers are accurate but expensive, which limits how often they can be called.
- Verifier training and verifier-guided search are usually studied separately.
2. Key ideas
- FlexiVe is a generative verifier that...

original1. Problems / challenges / motivations
- Retrieval-style memory injects a blob of past experience ahead of time, most of which is irrelevant to the current step.
- Irrelevant memory costs tokens, adds latency, and actively distracts the policy.
- Vector recall quality is not the same thing as memory being useful to an acting agent.

original1. Problems / challenges / motivations
- Multi-agent debate and collaboration results were mostly established on weaker base models and assumed to hold as models improve.
- Teams have no decision rule for when to add agents versus when a single strong model suffices.
- Collaboration adds cost and latency that need justification.
2. Key ideas
- Quantifies...

original1. Problems / challenges / motivations
- Multi-agent systems are adopted on the assumption that more agents means better results, with little controlled evidence.
- Comparisons across papers confound topology, model, and token budget.
- Errors propagate differently depending on how agents are wired together, and that effect is rarely measured.

original1. Problems / challenges / motivations
- Long context windows are marketed as capacity, and teams treat "fits in the window" as "will be used correctly."
- Needle-in-a-haystack tests use high semantic similarity between question and needle, which is the easy case.
- Without evidence of degradation, there is no case for the engineering cost of compaction and...
