GPT Image 2 vs GPT Image 1.5: The Verdict
GPT Image 2 vs GPT Image 1.5, decided by the data: speed will not decide this one — both models answer in roughly ~8s. Price does: GPT Image 2 at 10 credits undercuts GPT Image 1.5 by 0 credits per image. GPT Image 1.5 carries the higher rating (★★★★☆ vs ★★★★★), which tends to show up in detail and instruction-following. Run the same prompt on both before committing — same-latency pairs are exactly where per-prompt fit decides.
Two Generations, One Vendor
Same vendor, two slots: OpenAI ships both GPT Image 2 and GPT Image 1.5 precisely so workloads can move between them. GPT Image 1.5 (10 credits, ~8s) and GPT Image 2 (10 credits, ~8s) exist because OpenAI priced them for different jobs: one for throughput, one for polish. Both draw from one UnitPic balance here, so there is no penalty for splitting work between them — draft on one, finish on the other.

High-volume iteration and drafts
Pick: GPT Image 2Both are quick, but GPT Image 2 edges out GPT Image 1.5 (~8s vs ~8s per image). At exploration scale — dozens of variations — even a couple of seconds per image decides which model keeps you in flow.

Try This Prompt on Both
"An open cookbook with fresh herbs scattered across a marble counter, natural daylight" — fine detail against soft light: compare the herb leaves, the marble veining, and how each model keeps the page legible.
Run it on both modelsPricing Difference, In Numbers
Both models cost the same 10 credits per image, so price is not a differentiator here — decide on speed and style fit instead. And however the GPT Image 2 vs GPT Image 1.5 pricing math lands for you, credits on UnitPic work across every model in the catalog: buy once, spend on GPT Image 2, GPT Image 1.5, or anything else — no vendor lock-in.
GPT Image 2 vs GPT Image 1.5: FAQ
Which is better, GPT Image 2 or GPT Image 1.5?
It depends on your use case. GPT Image 2 is best known for image editing and multi-quality, while GPT Image 1.5 leans toward image editing and style switch. The most reliable way to decide: run the same prompt on both and compare the outputs side by side.
How much do GPT Image 2 and GPT Image 1.5 cost?
GPT Image 2 costs 10 credits per image on UnitPic, and GPT Image 1.5 costs 10 credits per image on UnitPic. UnitPic keeps it simple: one balance, any model, including both of these.
Which is faster, GPT Image 2 or GPT Image 1.5?
GPT Image 2 typically takes ~8s per image, while GPT Image 1.5 takes ~8s. Both are fast enough for interactive iteration — the difference mostly matters when you generate in batches.
Can I try GPT Image 2 and GPT Image 1.5 for free?
Yes — new UnitPic accounts start with 10 free credits, enough to generate on both models (20 credits for one image each). Sign up once — no API keys, no per-platform accounts.
