Bypassing inference bottlenecks: Accelerating complex AI search
This bypasses the heavy autoregressive "thinking budget" to instantly generate a cohesive, expert-level slate of AI search results. Quick links Paper Share Copy link × Modern search or recommendation applications are increasingly expected to return a coherent set of results rather than a single best match. For example, when a user searches for "camping gear", they don’t want ten slight variations of four-person tents.
