GLM-5.3 Flash
A large language model in the GLM series developed by Zhipu AI, belonging to the Flash (lightweight and fast) variant. The model features code comprehension and repair capabilities.

Timeline (last 90 days)
Zro released two uncensored model variants, Dolly 1 Security and Dolly 2 Security, based on GLM-5.3 Flash and GLM-5.3 respectively for abliteration processing.
GLM-5.3 and GLM-5.3 Flash are two specifications of the GLM series: the former has more complete capabilities and greater parameter count and inference overhead; the latter has undergone distillation or structural simplification, has lower inference cost, and is suitable for high-concurrency or resource-constrained deployments.
According to user measurements, GLM-5.3 High Speed generates at about 493 tokens per second, more than twice the peak of GLM-5.3 Flash.
If GLM is used to generate 10 drafts and the best one is selected, the result would be extremely close to Opus 5.5, while still being 20 times cheaper.
GLM 5.3 Flash's input price is only $0.15 per million tokens and output is $0.50, making it approximately one-twentieth to one-thirtieth the price of GPT-5.
Under the condition of only one attempt per task, GLM-5.3 Flash scored 85%.
With two to three attempts, GLM-5.3 Flash scored 82%, which is within the margin of error of GPT-5.6 Luna's 81%.
GLM-5.3 Flash relies entirely on domestically produced chips for training and inference, without depending on overseas AI chips such as those from NVIDIA.
GLM-5.3 Flash achieved nearly 20% weekly token call share on the OpenRouter platform, ranking first among all models.
The domestic chip route is an important enabler of GLM-5.3 Flash's 1/100 pricing, as freedom from dependence on imported computing power allows for a redesigned inference cost structure.
