Quick Navigation
How are GLM benchmarks tested in 2026?
Our 2026 GLM benchmark results are derived from rigorous testing across diverse scenarios. GLM benchmark results depend on consistent environments, so we used NVIDIA A100 GPUs in Beijing and Shanghai data centers to ensure uniform conditions. Test prompts were categorized into coding (Python/JavaScript), logical reasoning (math/ontology), and multilingual (10+ languages) workloads. For each model, including Doubao-Seedance-2-0-Fast, we ran 1,000 randomized queries to capture average performance and variability. Metrics tracked included First Token Latency (TTFT), tokens per second, and response accuracy. This methodology mirrors real-world API gateway usage patterns while maintaining scientific rigor.
