Jefferies analyst calls Z.ai’s GLM-5.2 model ‘another DeepSeek moment’

Beijing-based Zhipu AI has rattled Silicon Valley with the release of GLM-5.2, a 744-billion-parameter open-weight model that rivals Anthropic's Claude Opus 4.8 on coding benchmarks at a fraction of the cost. Jefferies strategist Christopher Wood described the past week as "another DeepSeek moment" in a research note, while the model's launch helped fuel a broader global tech sell-off and sent Zhipu's Hong Kong-listed stock soaring past HK$1 trillion in market capitalization.proactiveinvestors+2

A New Contender at the Frontier

Released on June 13, GLM-5.2 is a Mixture-of-Experts model with roughly 40 billion active parameters per token, a usable one-million-token context window, and an MIT license allowing free commercial use. On independent benchmarks, it ranks as the strongest open-weight coding model available, scoring 62.1 on SWE-bench Pro and 81.0 on Terminal-Bench 2.1 — within a few points of Claude Opus 4.8's 85.0. On the GDPval-AA benchmark, which measures real-world agentic work, GLM-5.2 sits at third overall globally.felloai+4

The model's API pricing starts at $1.40 per million input tokens, roughly one-sixth the cost of comparable closed-source alternatives. Jefferies' research note, reported by ANI on June 26, stated that "GLM-5.2 proves enterprises no longer need to pay frontier prices for frontier-adjacent performance" and argued that falling token costs could increase rather than reduce demand for computing infrastructure.facebook+2

Market Tremors

The launch amplified existing jitters in global tech markets. On June 22, Zhipu AI's Hong Kong-listed shares surged as much as 42% intraday to HK$2,980, briefly pushing its market capitalization above HK$1 trillion ($128 billion) — a gain of roughly 2,000% since its January IPO at HK$116.20. The South China Morning Post reported that the rally was "fuelled by investor optimism as the company goes head-to-head with its American rivals".ichongqing+2

The following day, a global tech rout saw South Korea's Kospi plunge nearly 10%, with Samsung Electronics and SK Hynix both falling more than 12%. The Nasdaq Composite closed down more than 2% as the sell-off spread to US markets, according to The Washington Post.cnbc+1

Widening Implications

Goldman Sachs The Goldman Sachs Group, Inc. ↗ 0.14% noted that GLM-5.2 represents "another Chinese open model that appears highly competitive on software-engineering benchmarks relative to the latest private models," adding that "the gap between open and closed systems is narrowing". Zhipu is now considering a multibillion-dollar secondary share sale in Hong Kong as its lock-up period expires in early July, Bloomberg reported.investing+2

The episode echoes the January 2025 DeepSeek shock that briefly wiped hundreds of billions from US tech valuations. This time, the challenge comes not from a single viral chatbot but from an open-weight model that developers can download, modify, and deploy without licensing fees — raising questions about how long US labs can sustain premium pricing for comparable capabilities.
