Nano Banana 2 Lite API — The Fastest, Lowest-Cost Gemini Image Model

Nano Banana 2 Lite (Gemini 3.1 Flash-Lite Image) generates images in about 4 seconds — roughly 2.7× faster than Nano Banana 2 — at native 1K across 14 aspect ratios. Built for rapid ideation and high-volume pipelines.

Around $0.034 per image at Google's published rate. Reach it through a single OpenAI-compatible EvoLink key — no Google Cloud project, billing, or quota setup.

Capabilities of the Nano Banana 2 Lite API

~4-second generation for high-velocity pipelines

Nano Banana 2 Lite delivers text-to-image in about 4 seconds — roughly 2.7× faster than Nano Banana 2 — so it fits interactive editors, chat-driven design tools, and high-volume batch pipelines. Faster round-trips mean tighter feedback loops and lower cost per iteration when you don't need 2K/4K output.

Generation, editing, and multi-image composition

The model natively handles text-to-image, image editing, and multi-image composition. Send a prompt and one or more images, get an edited or composed result in a single call. Fast multi-turn local edits — swap colors, create stickers, adjust backgrounds — happen inline without masks or layers.

14 aspect ratios with consistent characters

Cover 14 aspect ratios — 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, and 21:9 — across social, portrait, landscape, and cinematic formats. Character consistency and legible in-image text rendering carry over from the Nano Banana family.

Why developers choose Nano Banana 2 Lite API

When throughput and cost matter more than maximum resolution, Nano Banana 2 Lite is the Nano Banana 2 tier that keeps iteration fast and per-image spend low.

Tighter feedback loops

Generating at volume gets you more iterations for the same budget and wall-clock time. When you don't need 2K/4K, Lite keeps latency and cost down without changing your prompts or pipeline.

Predictable multi-turn editing

Character consistency holds across edits, so people, mascots, and products stay recognizable from first draft to final — no masks or layer management to babysit.

One key, zero setup

Access Nano Banana 2 Lite through EvoLink with a single API key. No Google Cloud project, no billing configuration, no quota requests. Same OpenAI-compatible format you already use.

How to integrate the Nano Banana 2 Lite API

Send a prompt (and optional image), pick an aspect ratio, and receive a 1K result in about four seconds.

1

Step 1 — Get your API key

Sign up on EvoLink (free) and grab your API key from the dashboard. Works with Nano Banana 2 Lite and 200+ other models instantly.

2

Step 2 — Send your request

POST to the EvoLink endpoint with your prompt and optional image (URL or Base64), set the output to 1K and pick one of the 14 aspect ratios. OpenAI-compatible format means minimal code changes when migrating.

3

Step 3 — Iterate and deploy

Receive the generated or edited image with its SynthID watermark. Run fast multi-turn edits, then save to your storage and ship across channels.

Key features of the Nano Banana 2 Lite API

Built for fast, high-volume image generation and editing

Speed

~4-second generation

About 4 seconds per generation — roughly 2.7× faster than Nano Banana 2 — so Lite fits real-time editors and large batch jobs where throughput matters more than maximum resolution.

Cost

Lowest cost in the family

Around $0.034 per 1K image at Google's published rate, the most cost-efficient tier of the Nano Banana 2 family for high-volume 1K workloads.

Editing

Editing + multi-image composition

Native text-to-image, image editing, and multi-image composition turn prompts and reference images into edited or composed outputs in a single call.

Formats

14 aspect ratios at 1K

Generate native 1K (1024×1024) across 14 aspect ratios including 1:1, 9:16, 16:9, and 21:9 for social, portrait, and cinematic formats.

Consistency

Consistent characters + readable text

Maintains character consistency and legible in-image text rendering from the Nano Banana family, keeping people, mascots, and labels recognizable across edits.

Provenance

SynthID by default

Every output ships with an always-on SynthID watermark for provenance and safe deployment.

Nano Banana 2 Lite API FAQs

Everything you need to know about the product and billing.

Nano Banana 2 Lite is the community name for Google's Gemini 3.1 Flash-Lite Image model (model ID: gemini-3.1-flash-lite-image). It is the fastest, most cost-efficient variant of Nano Banana 2, generating images in about 4 seconds at native 1K output.
Nano Banana 2 supports higher-resolution 1K, 2K, and 4K output for maximum quality. Nano Banana 2 Lite is optimized for speed and cost: about 4-second generation (roughly 2.7× faster) at native 1K only (no 2K/4K). Choose Lite for high-volume, latency-sensitive work, and the standard model when you need higher resolution.
Output is native 1K (1024×1024) only — 2K and 4K are not supported. It supports 14 aspect ratios, including 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, and 21:9.
Nano Banana 2 Lite generates a text-to-image result in about 4 seconds — roughly 2.7× faster than Nano Banana 2 — making it suitable for interactive editors, chat-driven tools, and high-throughput batch pipelines.
Google's published rate is about $0.034 per 1K image. In token terms that is $0.25 per 1M input tokens, $1.50 per 1M text output tokens, and $30 per 1M image output tokens (for ≤200K input tokens). EvoLink shows route-specific pricing in the pricing table and dashboard.
Yes. Every image carries an always-on SynthID watermark for provenance.
