Which Cloud Platform Delivers the Fastest DeepSeek‑R1 API? A Comprehensive Benchmark

Is it the original DeepSeek?

When developers use third‑party platforms to call DeepSeek‑R1, they often wonder whether the model is authentic and can fully leverage its capabilities. Several evaluation agencies and media outlets have tested the model on various cloud services to answer this question.

AIME Math Test Results

Using elementary‑level AIME reasoning questions, SuperCLUE found that ByteDance Volcano Engine, SenseTime, and Alibaba Cloud all achieved a 100% response rate. In terms of accuracy, Volcano Engine led with 95%, followed by Silicon Flow (94.74%) and Microsoft Cloud (93.33%). Alibaba Cloud had the lowest accuracy at 70%.

The AI Model Factory evaluated the same AIME dataset and reported the following correct‑answer rates: Volcano Engine 83.33%, DeepSeek official 73.33%, Alibaba Cloud 71.67%, and Tencent Cloud 58.33%.

Response Speed Evaluation

Baseline tests show that Volcano Engine’s first‑token latency is only 0.712 seconds, while Silicon Flow follows at 0.714 seconds. Alibaba Cloud’s latency is 1.262 seconds, and the DeepSeek official API is the slowest at 7.753 seconds. In generation speed, Volcano Engine reaches 68 tokens/s, DeepSeek official 37.425 tokens/s, and Alibaba Cloud 11.849 tokens/s.

8‑Hour Continuous Performance Test

The China Software Testing Center performed hourly sampling from 9:30 to 17:30. Most platforms kept token latency under 2 seconds, but Silicon Flow showed instability at 14:00 with a spike in latency.

Overall, Volcano Engine consistently delivered the fastest response and highest throughput across different cities, operators, and hosts.

API Stability and Concurrency

Stability tests across multiple dimensions (city, operator, host, time) show Volcano Engine maintaining high availability, even during peak traffic. Concurrency tests reveal that ByteDance’s DeepSeek model can handle up to 38 simultaneous users, while Silicon Flow, Alibaba, and Tencent support only 2–5 concurrent users.

Final Verdict

For developers seeking a reliable DeepSeek‑R1 API and enterprises demanding stable, high‑throughput service, Volcano Engine consistently outperforms other providers in speed, stability, and overall effectiveness.
