Accuracy Evaluations
Evidence
Throughput optimizations can sometimes quietly trade off accuracy (e.g. via aggressively relaxed acceptance rates, decoding tweaks, numerically unstable kernels, or endpoint misconfiguration)
Context After
Each representative throughput config now has an associated numerical accuracy check. Currently we are only using GSM8k, but being a very easy benchmark, the evaluation scores may not change much from differences in numerical calculation, and a harder benchmark may have a larger delta with respect to numerical accuracy. Thus, we plan to expand towards harder ones in the future, such as GPQA, HLE, MATH-500, SWE-Bench verified.
Another form of performance-accuracy tradeoff is quantization. Serving models at lower precision may result in worse model outputs. For DeepSeek R1, FP8 runs have very slightly higher evaluation scores than FP4. Note that GSM8k evals are saturated and often during QAT/PAT it is calibrated to common popular GSM8k, MATH-500, etc, leading to sometimes evals showing great results while real world end user evaluation being subpar. If we want to be part of the team to figure out how to properly evaluate inference engine accuracy, apply to join the mission here ↗.
② Atomic Claim
關於 InferenceX：Throughput optimizations 有時可能在不明顯的情況下犧牲 accuracy，例如過度放寬 acceptance rates、修改 decoding、使用數值不穩定 kernels，或 endpoint misconfiguration。
