GLM-5.3-Flash (EXL3 High)
GLM-5.3-Flash is a multimodal open-weight model by Z.AI. As a Mixture-of-Experts (MoE) architecture with 320B total and 18B active parameters, it combines efficiency with high performance. It supports a context window of 1 million tokens and processes text, image, and video inputs. The model is particularly optimized for complex agentic and coding tasks and is available under a permissive MIT license.

Sovereign Risk: MEDIUM The model was developed by Z.AI, a company headquartered in China (CN). The risk is classified as ‘medium’ rather than ‘high’ because the weights have been released under the very permissive MIT license. This reduces vendor dependency and mitigates some of the risks associated with Chinese jurisdiction. Nevertheless, a residual risk remains regarding training data provenance and potential regulatory influences.

Score
- Total Score
- Overall score derived from Routine and Reasoning scores. Basis for the fleet rank and tier assignment (Gold / Silver / Bronze / Standard).
- Routine
- Score for standard tasks: code generation, text transformation, structured outputs. Weighted by task complexity.
- Reasoning
- Score for analytical and logical tasks: multi-step problem solving, mathematical reasoning, structured argumentation.
- Rank
- Position in the fleet comparison, sorted by Total Score. Refers to the snapshot at the time of testing.
LLM Judge
- LLM Judge Ø
- Average quality rating by an independent judge model on a scale of 1–5.
- Coverage
- Share of tasks for which a judge rating is available. 100% means all responses were evaluated.
Latency & speed
- Avg. Task Duration
- Average time per task from the first to the last token of the response, measured across all benchmark tasks.
- Token Rate
- Output speed in tokens per second. Relevant for interactive applications and real-time streaming.
- P95 Latency
- 95th percentile of response times — shows outliers. Lower values mean fewer long wait times in edge cases.
Cost
- Cost per 1K
- API price per 1,000 output tokens in US dollars. Basis for cost calculation in production use.
- Benchmark Cost
- Total cost for the complete benchmark run of this model.
