White House Allows Anthropic's Mythos 5 Release as Chinese GLM 5.2 Matches Performance for 1/4 Cost

According to CNBC, on Friday, June 27, the White House allowed Anthropic to release its Mythos 5 model after a two-week shutdown due to export control directives, while OpenAI limited its GPT 5.6 rollout following government request.

Meanwhile, Chinese AI developer Zhipu's GLM 5.2, released earlier this month, performs on par with Mythos 5 on some cybersecurity benchmarks while costing roughly one-quarter per token. Major companies including Coinbase have begun shifting to Chinese open-weight models to reduce AI spending despite increased token usage.
