Z.ai drops GLM-5.3-Flash at one-tenth the cost
Z.ai just launched GLM-5.3-Flash, a 320B-parameter multimodal model that activates just 18B parameters and costs $0.045 per task—about a tenth of comparable alternatives. It crushes GLM-5.2 on coding and agentic benchmarks to near Claude Opus 4.8 levels, all while running entirely on Chinese AI silicon.
