Gemma 4 26B A4B vs GPT-4.1

Pick GPT-4.1 if you want the stronger benchmark profile. Gemma 4 26B A4B only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.

GPT-4.1 has the cleaner provisional overall profile here, landing at 58 versus 55. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

GPT-4.1's sharpest advantage is in knowledge, where it averages 66.3 against 49.2.

GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Gemma 4 26B A4B. That is roughly Infinityx on output cost alone. Gemma 4 26B A4B is the reasoning model in the pair, while GPT-4.1 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. GPT-4.1 gives you the larger context window at 1M, compared with 256K for Gemma 4 26B A4B.
