Zhipu GLM-5.3-Highspeed Hits 490 tokens/s in Zcode Gray Test

KEY FACTS

  • Zhipu has launched the GLM-5.3-Highspeed model, now in random gray release to subscribers on Zcode 3.15.1.
  • A user measured the model's output speed at 490 tokens/s.
  • The model has a context window of 1 million tokens and a maximum generation limit of about 128k.
  • The model offers three thinking intensity settings: low, high, and max.
  • Zhipu's GLM-5.1-highspeed, released in May this year, ran at 400 tokens/s.

PHYSIX OBSERVATION

If 490 tokens/s holds up, it will set a new speed ceiling for domestic large-model APIs, with long-horizon tasks and agent scenarios benefiting most directly. But the figure comes from a single user measurement, and the model is only in random gray release, so real-world stable throughput and pricing have not been announced. Zhipu's repeated use of high-speed versions to play the speed card shows that inference efficiency is becoming a new focal point of large-model competition.
