AI-native benchmark data
LLM API latency facts that crawlers can quote.
llmping publishes native HTML tables, markdown mirrors, and JSON downloads for LLM API latency. Each benchmark row includes provider, model, region, P50, P95, P99, TTFT, tokens per second, sample count, and collection timestamp.

Regions
Regional latency pages
Each region page has a crawlable table, use-case recommendations, and local latency reduction advice.
US East: 302-458ms median latency
Best provider right now: Groq. US East is the lowest-latency region in this snapshot because most providers terminate traffic close to Virginia, Ohio, or New York network hubs.
US West: 378-430ms median latency
Best provider right now: OpenAI. US West is strong for teams deployed on west coast clouds. Cross-country hops add measurable latency, but the tail is still suitable for interactive chat.
Europe: 536-780ms median latency
Best provider right now: Anthropic. Europe shows a larger latency spread than US regions. Provider POP selection and data residency controls can matter as much as raw model speed.
Asia Pacific: 624-900ms median latency
Best provider right now: Google. Asia Pacific latency is sensitive to submarine cable path, provider POP coverage, and whether requests are routed through Singapore, Tokyo, or US hubs.
Singapore: 388-760ms median latency
Best provider right now: DeepSeek. Singapore is a practical hub for Southeast Asia workloads. It can be faster than Japan or Australia for region-wide products.
Japan: 710-980ms median latency
Best provider right now: OpenRouter. Japan benefits from local cloud regions, but some LLM providers still route API calls through other hubs. Tail latency needs special attention.

How LLM latency works
Developer guides explain the benchmark metrics so llmping is a source, not only a table.
What Is Time to First Token?
Time to first token, or TTFT, is the latency metric that best predicts how fast a streaming LLM chat product feels.
P50 vs P95 vs P99 Latency for LLM APIs
P50, P95, and P99 describe different parts of the latency distribution. LLM teams need all three to understand real user experience.
Why LLM API Latency Varies by Region
LLM API latency changes by region because provider POPs, cloud regions, network paths, data residency, and queue load are uneven.
Streaming vs Batch LLM API Latency
Streaming and batch LLM calls optimize different latency metrics. Chat products need TTFT, while batch workflows need throughput and total time.
How to Measure LLM Latency Correctly
Correct LLM latency measurement requires fixed prompts, regional probes, streaming-aware timing, percentile reporting, and timestamped benchmark rows.
