gemini-3.1-flash-imagegemini-3.1-flash-image is Google's GA release of its efficient image model — high-quality generation and conversational editing at low latency, built for speed and high-throughput apps. Priced by resolution: $0.04 (512), $0.06 (1K and 2K alike), $0.10 (4K). Against Google's list price the 2K tier is the standout: $0.06 vs $0.101, 40% less. Because 1K and 2K cost the same here, moving up to 2K is free — at Google it is a 50% increase. Measured on our own traffic, half of all requests return in 14 seconds (median of 5,802 successful calls, 97.2% success rate). Text-to-image and reference-image editing across every tier. For maximum fidelity see gemini-3-pro-image; both share the same unified endpoint, so switching is a one-string change.
Google lists $0.101 for the same tier — 40% less here
Same $0.06 either way; at Google 2K is +50% over 1K

On apimodels.app it is priced per image by resolution: $0.04 (512), $0.06 (1K), $0.06 (2K), $0.10 (4K) — flat per image, not per token. Google's list price is $0.067 (1K), $0.101 (2K), $0.151 (4K), so the 2K tier is 40% cheaper here, 4K is 34% cheaper, and 1K is 10% cheaper. The 2K tier is the one worth knowing: 1K and 2K both cost $0.06 here, so moving up to 2K costs nothing, while at Google 2K is 50% more than 1K.
Measured on apimodels.app over 5,802 successful calls in the last 14 days: the median is 14 seconds, i.e. half of all requests return within 14s, at a 97.2% success rate. The mean is 24.8s — a minority of heavy requests pulls the average up, which is why the median is the honest number for typical experience. p90 is about 55 seconds.
No Google Cloud account is needed. Sign up at apimodels.app for an API key and POST to /api/v1/images/generations with model="gemini-3.1-flash-image". There is no Google Cloud project to create, no billing account to attach to Google, and no region to configure; the endpoint is reachable from mainland China. The same key and endpoint also serve every other image, video and LLM model on the platform — switching models is a one-string change.
gemini-3.1-flash-image is the fast, cheap option ($0.06 at 2K, 14s median) and suits batch generation, interactive apps and high-throughput workloads. gemini-3-pro-image has the higher ceiling on fidelity and text rendering, from $0.10. Use Flash for everyday volume and Pro for finished deliverables. Both sit on the same endpoint at apimodels.app, so moving between them changes one string, not your integration.
Yes — conversational editing runs on the same endpoint at the same price. Send a reference image plus a natural-language instruction ("change the background to an evening beach") and the model edits while preserving the subject. Text-to-image and reference-image editing are both available at 512, 1K, 2K and 4K with no surcharge.
Three reasons: (1) $0.06 at 2K against Google's $0.101 — 40% less — with 1K and 2K priced identically; (2) no Google Cloud project, billing account or region setup, and the endpoint works from mainland China; (3) one key covers every image, video, audio and LLM model on the platform rather than one integration per vendor. The honest trade-off: we are an aggregator, so in the worst case availability depends on upstream, and a direct Google integration gives you a firmer SLA.
