GLM-5.3-Flash is 320B-A18B, multimodal and roughly 9x cheaper than GLM-5.2's 744B-A40B. A verified head-to-head on specs, benchmarks, cost and self-hosting — plus the cases where GLM-5.2 still wins.
GLM-5.3-Flash ships 320B parameters in a 328 GB native-FP8 checkpoint, so the 18B active count tells you nothing about the memory you need. Here are the real hardware requirements by quantisation, plus working vLLM, SGLang, llama.cpp and Apple Silicon setups.
Z.ai's GLM-5.3-Flash is the model that ran anonymously as Ox Alpha: a 320B-total, 18B-active natively multimodal MoE with a 1M-token context and MIT open weights. Here are the verified specs, pricing and benchmarks.
Ox Alpha was Z.ai's GLM-5.3-Flash, confirmed on 26 August 2026. The free stealth preview has ended and the OpenRouter listing is gone. Verified specs, MIT-licensed weights, real pricing, and how to use the model now.
Hardware virtualization is the CPU feature that lets Android emulators, Docker, WSL 2 and Hyper-V run at native speed. Here's what VT-x and AMD-V actually are, how to check whether yours is on, and what to do if it isn't.
Verified Grok 4.6 API and subscription pricing as of 23 August 2026 - the $2/$6 token rates, the 200K long-context cliff, per-call tool fees, and worked cost examples.
