Claude Code median latency by provider and model, October 2026
Median provider latency in seconds for Claude Code traffic routed through Anthropic, Bedrock, and Vertex.
In October 2026 Vertex (Sonnet) was fastest at 2.6s median provider latency.
How does Claude Code latency vary by cloud provider? In October 2026 Vertex (Sonnet) was fastest at 2.6s median provider latency. Bedrock (Opus) was slowest at 6.1s.
Why it mattersThe same Claude model can run on Anthropic, Bedrock or Vertex. Latency differences between them are a reason to route by measured speed instead of pinning one cloud.
