Re Flare pairs its quality gains with a much shorter wait for images and edits, with GPT Image 2.5 Flare (max) having a ~63% faster latency than GPT Image 2 (high)
In our independent inference speed benchmarking, our preliminary results show similar improvements to OpenAI's claim of 50% lower latency for Flare versus GPT Image 2:
➤ Flare (max) reduced median generation time by 63%, from 142.9 to 52.7 seconds
➤ Sunburst (max) reduced median generation time by 24% to 108.9s
Our testing used 1024 × 1024 PNG outputs and represents a median across several testing runs including inference and image transfer.
