GLM 4.5V or GPT-5.4 Mini: which to pick

Only GPT-5.4 Mini has a coding score, 35.8 on the Vibe Coding Index; GLM 4.5V has none, so the two cannot be ranked on coding.

Pick GLM 4.5V for output tokens 2.5x cheaper ($1.80 vs $4.50 per million) and work measured by Kagi LLM Benchmark, where it leads.

Questions

Is GLM 4.5V better than GPT-5.4 Mini for coding?

Only GPT-5.4 Mini has a coding score, 35.8 on the Vibe Coding Index; GLM 4.5V has none, so the two cannot be ranked on coding. Pick GLM 4.5V for output tokens 2.5x cheaper ($1.80 vs $4.50 per million) and work measured by Kagi LLM Benchmark, where it leads.

Which is cheaper, GLM 4.5V or GPT-5.4 Mini?

GLM 4.5V costs $0.60 per million input tokens and $1.80 per million output tokens; GPT-5.4 Mini costs $0.75 and $4.50. Cost per solved task is known for GPT-5.4 Mini only.

Which has the bigger context window, GLM 4.5V or GPT-5.4 Mini?

GPT-5.4 Mini, with 400K tokens against 66K.

How many benchmarks is the GLM 4.5V vs GPT-5.4 Mini comparison based on?

37 benchmarks have a result for both models as of October 21, 2026. GLM 4.5V's coding index rests on 0 independent benchmarks and GPT-5.4 Mini's on 5. Where only one model has a result, the page says so instead of naming a winner.
