AI Model Comparison
Side-by-side comparison of pricing, context window, benchmarks, capabilities, and license. Every figure comes from the developer's own pages, last checked on ; each model's page lists its sources. A figure we could not source shows as a dash.
Model A — Z.ai (Zhipu AI)
GLM-5.3-Flash is the first natively multimodal model in Z.ai's GLM-5 series, with 320B total and 18B activated parameters and a hybrid of linear and sparse attention. Its weights are released under the MIT licence.
Model B — Alibaba
Qwen3.8-Flash is a multimodal Qwen model with a million-token context window, aimed at coding assistance, agentic workflows and visual understanding. It is the hosted version of Qwen3.8-Flash-Next, which Qwen describes as an experimental preview of the architecture that will underpin Qwen4.

Bold green values indicate the winner on that dimension where comparison is meaningful (lower price wins; bigger context wins; more open license wins; newer date wins). Prices are the ones each developer lists today; a model it no longer prices has none.
