Gemini 3.8 Flash เทียบกับ 3.7 Flash: เปลี่ยนไปแค่ไหน คุ้มค่าที่จะอัปเกรดไหม

Google has unveiled Gemini 3.8 Flash on November 2, 2026, just three weeks after the release of Gemini 3.7 Flash on September 13, 2026. Both models share the same pricing structure, with input costs ranging from $0.75 to $1.50 per 1 million tokens and output costs from $3.75 to $7.50 per 1 million tokens until December 31. The key change lies in the internal workings: Gemini 3.8 Flash utilizes a smaller reasoning step, self-checks its outputs, and calls itself repeatedly, resulting in higher benchmark scores but increased token usage.

The question is not whether Gemini 3.8 Flash is better, as the available data suggests it is, but whether the added performance is worth the additional token usage and potential compatibility issues with existing code. Key points to consider include the cost, changes in code functionality, and the decision-making process based on task type.
