SAGG, a DeepSeek gateway provider, published benchmark results measuring whether automatic failover across multiple providers actually reduces request failures in production. The numbers show it does, but unevenly: the gateway's value depends entirely on which provider tier is failing and whether your backup tier has better uptime than your primary.

How the Benchmark Worked

The test sent paired requests: the same prompt at the same instant, once directly to a proxygonka-deepseek endpoint and once through the SAGG gateway on the same connection. Pairing controls for prompt difficulty and provider conditions changing over the three-day run. A "request saved" means the direct path failed and the gateway succeeded on the same prompt at the same moment.

This is a more rigorous design than most gateway reliability claims. Sending identical prompts at identical times eliminates the variable of prompt complexity and isolates the gateway's failover behavior as the only difference between the two paths.

Standard Line: Clear Win

On SAGG's Standard line, 254 out of 720 direct requests failed, a 35.3 percent failure rate. The gateway failed on 152 of the same 720 pairs, a 21.1 percent rate. That is 126 requests saved, with a McNemar's exact p-value of 8.8 times 10 to the negative 13. The result is statistically unambiguous.

The gap is large enough to matter in production. If your application makes hundreds of DeepSeek API calls per day, a 14-percentage-point reduction in failure rate is the difference between a degraded afternoon and a normal one.

Super Deal Line: Smaller Benefit

Super Deal's numbers were worse across the board. Direct failures hit 37.2 percent, and the gateway still failed on 33.5 percent of pairs. Only 51 requests were saved, with a p-value of 0.0024. Still statistically significant, but the practical benefit is much smaller.

The explanation is in the provider data. Super Deal's backup tier is measurably less reliable than Standard's. When your primary fails and your backup also fails, the gateway has nothing to fall back to. Failover only helps if at least one tier in the chain is up.

Provider Reliability During the Test Window

SAGG ran 25 direct requests to each of the four providers individually to measure standalone reliability during the same three-day window. The results paint a picture of a network-wide condition, not isolated bad days:

  • proxygonka-deepseek: 68 percent failure rate, 71.5ms median latency
  • gonkaapiorg-deepseek: 36 percent failure, 726.5ms median latency
  • eterial-deepseek: 48 percent failure, 74ms median latency
  • deepinfra-deepseek: 4 percent failure, 5648.5ms median latency

All three Gonka-network brokers showed elevated failure simultaneously. DeepInfra, the only non-Gonka provider, stayed at 96 percent success. This is exactly the scenario a multi-provider gateway is designed for: when the primary network has a systemic problem, routing to a provider on a different network avoids the outage entirely.

The latency difference is notable. DeepInfra's median response time was 5.6 seconds, roughly 75 times slower than proxygonka-deepseek's 71.5 milliseconds. The tradeoff is clear: DeepInfra is dramatically more reliable but substantially slower. For applications where latency matters, this is a real cost of the fallback.

A Real Failover Trace

SAGG published raw JSONL trace data from production requests, including one that hit all three tiers before succeeding. The primary provider timed out after 3 seconds. The first backup timed out after 15 seconds. The second backup, DeepInfra, succeeded at 15.4 seconds total. Slow, but it completed instead of failing.

The trace shows the reality of failover: it is not free. The 15-second SLA per leg means a worst-case request takes 45 seconds before the gateway gives up. For applications with tight latency budgets, that worst case may be unacceptable even if it avoids a hard failure.

Provider Conditions Move Fast

In a separate check, proxygonka-deepseek went from 68 percent failure to 0 percent failure within roughly 10 to 15 minutes. Sixteen out of sixteen real gateway calls succeeded on the primary tier after the window improved. This means any single measurement is a snapshot, not a verdict. Provider reliability on the Gonka network fluctuates rapidly, which is both the problem and the argument for a gateway that can route around bad windows in real time.

What This Means for Teams Using DeepSeek

The benchmark confirms two things. First, automatic failover across providers measurably reduces failures when the primary network is degraded. The Standard line result is strong and statistically clean. Second, the benefit depends entirely on your backup tier being more reliable than your primary during the failure window. If both tiers are on the same degraded network, the gateway has nothing useful to fall back to.

For teams evaluating DeepSeek gateway providers, the practical questions are: what providers does the gateway actually route to, are they on different networks, and what is the latency cost of the fallback tier? The failure rate reduction is real, but it comes with a latency tradeoff that matters for interactive applications. A 15-second worst case is fine for batch processing and unacceptable for a chat interface.

The raw data, the McNemar test script, and all trace files are published alongside the benchmark, which is more transparency than most gateway providers offer. Whether the numbers represent a typical week or a particularly bad one for the Gonka network is the open question, and SAGG is honest that provider reliability moves fast enough that no single measurement should be treated as permanent.
