2026/06月初,google新出了gemma4 12b,起初我認為它是最適合rtx5060ti 16GB的模型。但實測後Q4版本大概能跑到37~43 token/s,而Q6版本則是32 token/s左右,速度是還能接受,上下文也可以到131072,使用Qat的版本上下文能到256K,顯存能夠全開。
但是gemma-4-26B-A4B測試下來目前有兩個模型
gemma-4-26B-A4B-it-qat-q4_0-gguf
gemma-4-26b-a4b-it-ultra-uncensored-heretic-ud
他們能夠控制在16GB顯存內,使用gemma-4-26B-A4B Q4版本的模型,前陣子16GB顯存最多只能用Q3版本的。但最近新出了幾個版本讓Q4正好在16G顯存內。
不過使用它們,沒法將上下文全開,實測下來最多大概就是50K,linux版本估計能更好一些。
最令我興奮的是gemma-4-26B-A4B Q4版本,可以跑到77.79token/s 啊~~~

輸出的品質,我自己覺得兩者差不多,gemma-4-26B-A4B Q4略好一點,但要是這樣的話,無論是智力還是速度上,12B都輸了啊~ 只贏在上下文能到256K
但我真要上下文多的情況,估計也會挑別的模型,這新出的12B模型,反而被之前的模型給比下去了。不過它還是有它的用處,例如它適合給12GB顯存的顯卡使用
但這又得去比較一下,是gemma-4-12B厲害,還是qwen3.5-9B厲害了。
對了,gemma-4這次除了官方模型以外,其它模型在lm studio都會遇到錯誤,查了一下是jinja模板解析錯誤,我用官方那個模型的jinja替換這些出錯的模型就能使用了。
