    Anthropic warns GLM-5.3 has serious cyber capabilities and almost no guardrails

    Anthropic just published a red-team evaluation of Zhipu AI's open-weight GLM-5.3, revealing that it can autonomously develop end-to-end cyberexploits on par with Claude Mythos Preview. Even worse, researchers bypassed its safeguards up to 100% of the time, dropping refusal rates to roughly 2% for just $4,400 in compute. Why it matters: Frontier-level offensive cyber tools are now freely downloadable with virtually zero effective restrictions.

    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.
