GLM-5.2 Performance Benchmark: A New Paradigm for Multimodal Inference on GB10 Clusters

Event Core

Zhipu’s GLM-5.2 (Int4/Int8) demonstrates exceptional inference efficiency on an 8× GB10 GPU cluster, achieving a prefill speed of ~1,200 t/s and a sustained decode throughput of 33–54 t/s, while maintaining sufficient VRAM headroom to concurrently run the Mimo 2.5 multimodal model.

Bagua Insight

• ▶ Shift in Compute Efficiency: The GB10 architecture, when paired with TP8 (Tensor Parallelism), proves that high-throughput inference no longer requires dedicated hardware silos. The ability to stack models suggests a shift toward more dense, multi-model deployment strategies in enterprise production.
• ▶ Engineering Multimodal Synergy: Running GLM-5.2 and Mimo 2.5 simultaneously on the same cluster validates the feasibility of unified compute orchestration for complex AI Agents, effectively reducing the TCO (Total Cost of Ownership) for multimodal pipelines.

Actionable Advice

• Optimize Deployment Density: Organizations should audit their current inference workloads. With high-end hardware like the GB10, focus on maximizing VRAM utilization by co-locating complementary models rather than scaling individual instances.
• Prioritize Quantization: The 33-54 t/s decode performance confirms that Int4/Int8 quantization is now production-ready for latency-sensitive applications. Shift focus from raw precision to throughput-optimized serving architectures.
