DIRECT: When and Where Should You Allocate Test-Time Compute in Embodied Planners?

arXiv:2606.12402v1 Announce Type: cross Abstract: Vision-Language Models (VLMs) are increasingly deployed as high-level planners for embodied agents, with an emerging strategy of scaling test-time compute to improve capability. However, we observe that doing so increases latency, token usage, and FLOPs while yielding uneven, often diminishing gains in downstream success, limiting where embodied agents can be deployed. We argue that choosing when and where to spend test-time compute is central to bringing frontier performance to the real world. We introduce DIRECT, a routing framework that uses

Why this matters
Why now

The proliferation of high-latency, high-cost Vision-Language Models in embodied AI necessitates immediate solutions for efficient compute allocation.

Why it’s important

Optimizing test-time compute for embodied planners directly impacts the economic viability and practical deployment of AI agents in real-world scenarios.

What changes

The focus in embodied AI shifts from merely increasing compute to strategically managing it, enabling more efficient and widespread adoption of VLM-driven agents.
