Zhipu ships GLM-5.3-Flash: frontier intelligence at flash pricing
Zhipu's official blog announced GLM-5.3-Flash (the renamed ox-alpha the community had been tracking): ~321B-total MoE at FP8 mixed precision, MIT-licensed weights, zh/en with 400K context. A hands-on megathread opened on r/LocalLLaMA the same day, and third-party comparisons put it near Claude Opus at roughly a tenth of the price — a price-anchor event for the frontier market worth sustained tracking.
[Evidence provenance: official blog and HF card plus third-party retelling] The "Opus-level at a tenth of the price" framing follows AlphaSignal's comparison, not an independent review; local hands-on numbers await the megathread, and attention is not proof.
