Fastest LLM API 2026

Real benchmark rankings by tokens/second and time-to-first-token

This page ranks LLM APIs by measured throughput and latency using automated benchmarks run against the live production endpoints. Data reflects rolling averages — not vendor claims. Last updated: 2026-06-11. For real-time data, see the live cloud benchmarks.

Key Insights

  • Inference-optimized providers (Groq, DeepInfra, Fireworks) consistently deliver 100–300+ tokens/second — 3–10× faster than direct OpenAI/Anthropic APIs.

  • High throughput does not equal low latency: time-to-first-token (TTFT) is what matters for streaming UX. Groq and DeepInfra often have near-zero TTFT.

  • AWS Bedrock Nova Micro reaches ~118 tok/s with ~380ms TTFT — the fastest option if you need AWS-native data residency and compliance.

  • For most coding assistants and chatbots, 60–80 tok/s is imperceptibly fast in streaming mode. Chase lower TTFT before chasing higher throughput.

  • Benchmarks reflect rolling averages from automated runs. Provider speeds change week-to-week; check the live data before committing to a provider.

How to Choose

Need the absolute fastest response?

Use Groq or DeepInfra. Both consistently top the throughput charts with near-zero TTFT. Best for real-time voice, gaming, or low-latency chat.

Need speed + frontier model quality?

Fireworks runs many of the same open-weight models as Groq with competitive speeds. For proprietary frontier models, OpenAI GPT-5 Nano reaches ~91 tok/s with high quality.

Need AWS-native compliance?

AWS Bedrock Nova Micro hits ~118 tok/s — best-in-class for VPC-native, SOC2-compliant workloads within the AWS ecosystem.

Batch processing / cost-sensitive?

High throughput providers are also cheaper per token. Compare pricing on each provider page alongside speed.

Frequently Asked Questions

Groq and DeepInfra lead raw throughput benchmarks, regularly exceeding 150 tokens/second on mid-sized models. For the absolute highest speed on a capable model, Groq's Llama-3.3-70B at ~154 tok/s is a strong choice as of June 2026.

60–80 tok/s is generally imperceptible for streaming output. Above 100 tok/s is excellent. Below 30 tok/s starts to feel slow in interactive chat. For batch processing, throughput matters more than TTFT.

Yes — Groq's inference hardware consistently delivers 3–10× higher throughput than OpenAI's API for equivalent model sizes. The tradeoff is model selection: Groq offers fewer frontier models than OpenAI.

TTFT is the delay between sending your API request and receiving the first token of the response. It determines how quickly a streaming response starts appearing. For interactive UX, TTFT under 500ms is preferred.

Methodology

All benchmarks are collected by automated scripts that send standardized prompts to each provider's production API and measure wall-clock time from request dispatch to final token. Tokens per second is calculated from the completion length and total generation time. TTFT is measured as the gap between request start and first streaming chunk. Runs are aggregated over a rolling window; the table above shows means from the most recent 7-day window. Providers are not notified before benchmark runs.
