Google Cloud and Reflection report up to 5× higher performance and 8× lower latency for Beam using llm-d with vLLM or NVIDIA Dynamo with SGLang. The serving recipes and reported gains are relevant to teams running large models for agent workloads.

What
Beam is an open-weight model for software engineering and long-horizon agentic tasks, with about 501B total and 23B active parameters.
How
The serving setups pair llm-d with vLLM or NVIDIA Dynamo with SGLang, using techniques including KV-cache-aware routing and prefill/decode disaggregation.
Why it matters
Google Cloud reports up to 5× higher throughput and 8× lower latency on A4X Max instances for the optimized serving setup.
with with Beam llm-d NVIDIA Dynamo vLLM SGLang
Beam is served through either of the two described inference stacks. Sketched from the article's own text.
