Two of the most requested image models on Apifuse are Google's Nano Banana 2 and OpenAI's GPT Image 2. They overlap on quality but diverge on the details that matter for production work.
Text rendering
Both handle short labels well. GPT Image 2 edges ahead on dense, multi-line text and signage, where glyphs stay crisp at 4K. Nano Banana 2 is close behind and noticeably faster.
Prompt adherence
Nano Banana 2 follows compositional instructions — counts, placement, relationships — with fewer retries. GPT Image 2 is stronger on photoreal lighting and material detail.
Price and verdict
At Apifuse rates, Nano Banana 2 is the better default for high-volume generation; reach for GPT Image 2 when text fidelity or photoreal detail is the priority. Because both sit behind one key, you can route per request without changing clients.
