Nova 2 Lite vs GPT-5 Mini
Updated October 21, 2026. 29 benchmarks have a result for both. Coding is ranked on the Vibe Coding Index; every other board is shown as published.
Decision reading
Only GPT-5 Mini has a coding score, 34.2 on the Vibe Coding Index; Nova 2 Lite has none, so the two cannot be ranked on coding.
Nova 2 Lite has the edge where the context window is larger, 1M against 400K tokens, and where what matters is LMArena Text: software and IT or LMArena Text: hard prompts in English, where it leads.
