Veo 3.1 — cinematic AI video, paid per clip

Veo 3.1 is Google DeepMind's state-of-the-art video generation model — as of mid-2026, the latest public version, with no Veo 4 announced. It turns a text prompt or a still image into a 4-to-8-second clip with synchronized native audio: dialogue, ambient noise and sound effects generated in the same pass as the pixels. The family has three tiers that share one skill set and differ in fidelity and price: Veo 3.1 for final renders, Veo 3.1 Fast for fast iteration at roughly a third of the cost, and Veo 3.1 Lite for storyboards and drafts from $0.10. On BananaBanana all three run in production behind one balance — you choose the model, resolution (up to 4K on Veo 3.1 and Fast), duration and audio toggle, and pay a fixed price per clip.

Use Veo 3.1 Lite (from $0.10 silent) to test ideas and lock your prompt — it renders up to 1080p and costs less than a tenth of the flagship. Move to Veo 3.1 Fast (from $0.35) when the concept works and you want production speed; it supports 4K and is the workhorse for social content. Reserve Veo 3.1 (from $0.70) for hero shots where visual fidelity is the point — client reels, ads, title sequences. All three accept the same prompts, so the cheap-to-expensive workflow costs a fraction of re-shooting on a flagship-only platform. A typical pipeline: three Lite drafts (~$0.30), one Fast 1080p take (~$0.35), one final 8-second 4K render with audio on Veo 3.1 ($4.40) — a finished cinematic clip for about five dollars.

Veo 3.1, Veo 3.1 Fast and Veo 3.1 Lite are available through the same two routes as the rest of the platform, at the same per-clip prices as the web generator: from $0.10 on Lite, $0.35 on Fast and $0.70 on Veo 3.1. Our MCP server at https://bananabanana.pro/api/mcp (Streamable HTTP) accepts OAuth or an API key from your profile; an agent calls generate_video with the model, duration, resolution and audio setting. Video is quoted before it is charged: the first call returns the exact price, and rendering starts only after the agent confirms it. The clip renders in the background, the agent fetches the file with get_result, and a failed render is refunded automatically. Without an account, x402 lets an agent pay for one clip in USDC on Base and collect it by job_id; if a paid clip fails, the agent receives a credit token for the full amount.

A little, and here is exactly how much. New accounts start with a free $0.20 balance; signing up needs no card and no crypto. On Veo 3.1 Lite that covers 2 silent 4-second clips at $0.10 each. Veo 3.1 Fast (from $0.35) and Veo 3.1 (from $0.70) cost more than the welcome balance, so they need a top-up with crypto or a card. There is no subscription and nothing renews. Lite takes the same prompts as the larger models, so the free clips are a fair test of a prompt before you pay for a Fast or 4K render.
