Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.
Llama 4 Maverick is clearly ahead on the aggregate, 42 to 31. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5 nano is also the more expensive model on tokens at $0.05 input / $0.40 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Llama 4 Maverick. That is roughly Infinityx on output cost alone. GPT-5 nano is the reasoning model in the pair, while Llama 4 Maverick is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Llama 4 Maverick gives you the larger context window at 1M, compared with 400K for GPT-5 nano.
Pick Llama 4 Maverick if you want the stronger benchmark profile. GPT-5 nano only becomes the better choice if mathematics is the priority or you want the stronger reasoning-first profile.
