Self-host break-evenInclude engineering labor

At 10,000 images/mo, it’s a toss-up against a quality API like FLUX.2 [pro] ($0.03/image). Self-hosting beats it on raw compute (break-even ~6,634/mo), but the engineering time usually erases the savings until ~14,967/mo.

◆ = tinytiny.tools has a referral link for this provider. Prices verified 1 de julio de 2026 and normalized to a 1024×1024 standard-quality image; per-megapixel and per-token models are scaled by output area (≈4× at 2K, ≈8× at 4K — an estimate, since per-token models bill by size tier). Self-host break-even compares a flat-rate ~$199/mo GPU (one server tops out near ~170k images/mo) against a quality-matched API. This space changes monthly — confirm current pricing on each vendor’s page before you commit.

Common questions

How does this calculator estimate cost per image?: Every model is normalized to one standard 1024×1024 (1 MP) image. Flat per-image prices are used as-is; per-megapixel and per-token prices are scaled by output area when you raise the resolution. Monthly cost is that per-image price × your volume, and the table re-sorts to surface the cheapest option for your exact inputs.
Why is the self-host break-even measured against FLUX.2 [pro]?: Self-hosting an open-weight model (FLUX.2 [dev], SDXL) is a quality play — you do it to avoid paying for a production-grade API, not to beat a near-free budget one. So break-even is measured against a fixed, quality-matched reference (FLUX.2 [pro] at ~$0.03/image): ~6,600 images/mo against a ~$199/mo GPU on raw compute, or ~15,000 once you price the engineering time to run the stack.
What does changing the resolution setting do?: It rescales the size-dependent billing models. Per-megapixel and per-token prices grow with output area — about 4× at 2K and 8× at 4K — while flat per-image pricing is unchanged. Per-token rows are an estimate at higher resolutions, since those providers bill by discrete size tier rather than continuous megapixels.
How current are these prices, and how are they updated?: Prices were verified on 2026-07-01 against each vendor's pricing page and normalized to a 1024×1024 image. They're refreshed monthly from a single source of truth, so this tool and the accompanying guide always agree — but this space moves fast, so confirm current pricing on the vendor's page before committing.
