How does Claude Code latency vary by cloud provider? In April 2026, Anthropic Haiku is the fastest at 1.8s median provider latency. Opus latency is remarkably consistent across providers (4.5-4.9s). Vertex Sonnet is the slowest at 6.2s, roughly 40% slower than the same model on Anthropic direct.

Why it mattersProvider choice affects both latency and reliability for the same model. Anthropic direct offers the lowest latency for Haiku and Sonnet, while Bedrock provides higher cache hit rates. Vertex delivers the fastest TTFT for Sonnet but the slowest total completion time. These tradeoffs matter for coding agents that make 50-200 API calls per session.
