GLM5.3
An open-source large model version in Zhipu AI's GLM series, aimed at general-purpose and agent tasks.
Timeline (last 90 days)
On public benchmarks, DeepSeek 4.1 Flash exceeds its predecessor by several percentage points on most dimensions such as intelligent coding, common sense, and automation, leads open-source models such as GLM5.3 and Kimi K3, and is roughly on par with some top closed-source models; it ranks third on the GPU code benchmark.
On benchmarks for agentic coding, general agents, knowledge, automation and others, DeepSeek C.E Flash 1017 improves by several percentage points over the previous generation, beats open-source models such as GLM5.3 and Kimi K3, and performs almost on par with GPT-5.6 Sol.
Artificial Analysis data shows that the task cost of the same GLM5.3 model differs by about 9x across different providers, and the gap is related to cache hit rate and token pricing.
Terminal Bench 4.0's 42.3 points surpass GPT5.6 Soul and GLM5.3, but there is still a 22-point gap to Claude Opus 5.5's 64.8 points.
Among the 38 free models, only 4 are suitable for writing code: GLM5.3, DeepSeek 4.1 Flash, Nemotron 3 Ultra, and Poolside Laguna XS 2.1.
Anthropic reported on September 30 that the open-source model GLM5.3's vulnerability exploitation capability was close to that of Cloud Mythos Preview and that its safety restrictions could be easily bypassed, concluding that advanced cyberattack capabilities are spreading into the open-source ecosystem.
A developer states that GLM5.3 has been used to inspect 389 open-source projects, uncovering 4,249 potential vulnerabilities.
