GPT-5.4 vs GLM-4.5VWhich is better in 2026?

Comparing GPT-5.4 and GLM-4.5V across benchmarks, pricing, and capabilities.

Verdict: GPT-5.4 vs GLM-4.5V — which is better?

GPT-5.4 (by OpenAI) and GLM-4.5V (by Zhipu AI) are two of the AI models people compare most. Here is how they stack up on benchmarks, price and capabilities, and which one to pick in 2026.

On price, GLM-4.5V is roughly 5.9x cheaper per token on a blended 3:1 input/output basis, which adds up quickly at production volume.

GPT-5.4 also accepts a larger context window (1,000,000 input tokens), making it the stronger choice for long documents and large codebases.

Choose GPT-5.4 if…

  • you process long inputs — it offers a 1,000,000 token context window
  • you want the most recent training data — it shipped Mar 2026

Choose GLM-4.5V if…

  • cost matters — it's about 5.9x cheaper per token
  • you need open weights you can self-host or fine-tune
