Decision reading

GLM 5V Turbo and GPT-4.1 Mini are level for coding, 28.8 against 28.5 on the Vibe Coding Index, so price and context decide.

Pick GPT-4.1 Mini when output tokens cost 2.5x less, or when the context window is larger, 1.05M against 203K tokens. Pick GLM 5V Turbo when what matters is Terminal-Bench Hard (Artificial Analysis run) or LMArena Text: coding, where it leads.
