The Real Cost of Text to Image APIs in 2026

Why Pricing Comparison Matters

Text to image API pricing varies wildly across providers. OpenAI charges $0.040 per image for DALL-E 3, while ModelsLab is a flat $0.0047 per image — about 8.5x cheaper. At production volumes, this gap becomes thousands of dollars per month. Understanding the true cost of each provider is critical before committing your infrastructure.

This comparison breaks down per-image costs, volume pricing, hidden fees, and total cost of ownership across the six most popular text to image API providers in 2026: ModelsLab, OpenAI, Stability AI, Leonardo AI, fal.ai, and Replicate.

Hidden Costs to Watch For

Per-image price is not the whole story. Watch for these cost traps:

  • Resolution upcharges — Some providers charge 2-4x more for 1024x1024 vs 512x512
  • Model switching fees — Locked into one model? Switching costs add up fast
  • Cold start overhead — Pay for wasted compute while models spin up
  • Rate limit overage — Unexpected charges when you exceed plan limits
  • Storage fees — Some providers charge for generated image hosting
  • API call minimums — Monthly minimums that inflate low-usage costs

Per-Image Pricing Comparison

What each provider charges per image at standard resolution (1024x1024).

Text to Image API Pricing FAQ

ModelsLab is the cheapest unified API for 10,000+ models at a flat $0.0047 per image. This is about 8.5x cheaper than OpenAI DALL-E ($0.040) and cheaper than Stability AI ($0.006), and competitive with fal.ai ($0.005) and Replicate. At scale it is even cheaper: the $149/month unlimited plan works out to ~$0.0015/image at 100k+ images per month.

DALL-E 3 costs $0.040 per image at standard resolution and $0.080 at HD. ModelsLab costs $0.0047 per image at 1024x1024 with no resolution upcharges. At 10,000 images/month, DALL-E costs $400 vs ModelsLab $47 (pay-as-you-go).

ModelsLab is a paid service — plans start at $21/month (Basic, 3,250 API calls) and include access to all 10,000+ models including Flux and SDXL. Creating an account is free; API generation requires an active plan. Stability AI offers 25 free credits/day and fal.ai gives $1 in free credits.

ModelsLab's unlimited plan is $149/month with access to 10,000+ models — far more than Leonardo AI's $48/month unlimited, which is limited to its own models. For most workloads ModelsLab's $0.0047/image pay-as-you-go is among the lowest-cost options, and it is a flat rate across all 10,000+ models with no per-model upcharge. OpenAI and Stability AI do not offer unlimited plans.

At 100,000 images/month: ModelsLab $149 (unlimited) vs OpenAI $4,000, Stability AI $600, fal.ai $500. ModelsLab's flat $149/month is the most cost-effective option at very high volume (above ~100,000 images/month).

Yes — on the $149/month Open Source Unlimited plan, every open-source model (Flux, SDXL, Qwen, WAN, and more) hosted on our own infrastructure gives you unlimited generations with zero credit deduction. You also get 15 parallel API requests, so multiple generations can run at once instead of queuing one by one.

Yes, if you plan to use any premium third-party model. The $149/month subscription covers unlimited open-source generations and 15 parallel requests — it doesn't include any wallet credit. Add funds separately whenever you want to call Google, Kling, Seedance, or other premium APIs.

No. ModelsLab is paid-only — there is no free tier, no free credits and no trial plan. Plans start at $21/month (Basic), which includes 3,250 API calls and access to every model in the catalogue. To judge a model before subscribing, open its page: each one shows example outputs and the exact request body you would send.

Yes. Wallet top-ups are for active subscribers, which is why no "Add Funds" option appears on an account with no plan. Subscribe to any plan and wallet funding unlocks. Accounts that already held a wallet balance keep the ability to top up.

Your plan allowance resets at the start of each billing period and unused allowance does not carry forward. Wallet balance works differently: money you have topped up stays on the account until you spend it, and is not cleared when the plan renews.

Open-source models we host ourselves — Flux, SDXL, SD 1.5, WAN and similar — are unlimited on the $149/month Open Source Unlimited plan. Premium third-party models such as Google, Kling, Seedance, Vidu and ByteDance are billed per call from your wallet on every plan, including the unlimited one. The pricing tables on this page carry an "Unlimited" column marking exactly which models are included.

Video is priced per second of output or as a multiplier on the model's base rate, depending on the provider — the exact rate for each model is in the AI Video table on this page. A single video clip can cost considerably more than an image, so check the rate for your chosen model before running a batch.

Basic at $21/month includes 3,250 API calls and 5 concurrent requests. Standard at $47/month includes 10,000 calls and 10 concurrent requests. Open Source Unlimited at $149/month removes the call limit on open-source models and allows 15 concurrent requests. Every plan can reach every model — plans differ on volume and concurrency, never on which models you may use.

Cancel from Dashboard → Subscription at any time. Cancelling stops future renewals and you keep access until the end of the period you have already paid for. Monthly and yearly plans carry a 100% refund policy — email support@modelslab.com if you would like a refund processed or if the cancellation flow does not complete for you, and we will handle it directly.

Yes. Output you generate through the API is yours to use commercially on every paid plan. Individual third-party models can carry their own upstream licence terms, so check the model page if you are building on one specific closed-source provider.

Yes. The agent control plane at /api/agents/v1 covers the whole lifecycle: POST /auth/signup creates the account, POST /billing/payment-link returns a Stripe checkout URL, POST /subscriptions starts a plan, and POST /api-keys issues the key. An agent can go from no account to a working API key without a browser. Plans start at $21/month for 3,250 API calls; ModelsLab is paid-only, so a subscription is required before generation.
