Longer context means higher time-to-first-token (TTFT), and token count is directly linearly correlated with inference costs.

UnverifiedHigh aggregate throughput often comes at the cost of larger batch sizes, and large batches drive up the time-to-first-token (TTFT) latency for individual requests.77% similarVerifiedThe KV cache VRAM usage of ultra-long context windows grows linearly with context length, causing inference latency and costs to rise significantly.72% similarUnverifiedThe High configuration with extended chain-of-thought reasoning needs to process a large number of internal reasoning tokens during the prefill stage, so TTFT is typically several to tens of times that of the standard version.71% similarVerifiedInference latency is typically decomposed into two core metrics: time to first token (TTFT) and subsequent token generation throughput.71% similar
