AI API prices by modality

List prices for the models ModelsLab runs on its own GPUs. They are the same on the $21 Basic and $47 Standard plans. Each plan is a dollar allowance, not a call count.

When a flat plan costs less than paying per call

The $149 Open Source Unlimited plan has no per-generation charge on self-hosted models. It costs less than list price once your monthly volume passes these points.

Monthly volume at which the $149 plan costs less than self-hosted list prices
WorkloadList price$149 costs less above
Images$0.0047 per image~31,700 images a month
Wan 2.2 clips$0.075 per clip~1,990 clips a month
Speech$0.001 per second~41 hours of audio a month

Above that point, extra self-hosted generations cost nothing more. The limit is 15 parallel generations.

Where ModelsLab is not the cheapest

LLMs. Our LLMs are partner models, billed per million tokens: from the plan allowance first on Basic and Standard, then the wallet, and from the wallet on the $149 plan. A flat plan does not lower their price. Check the per-token rates before you pick a provider, for example on the DeepSeek API pricing page.

Plans from $21 a month

Basic is $21, Standard $47 and Open Source Unlimited $149 a month ($210, $451 and $1,500 a year), with 5, 10 and 15 parallel generations. One subscription and one API key cover image, video, speech and LLM. Creating an account is free; API calls need a plan.

For open-source models, a flat plan is cheaper than per-call pricing once volume grows. On ModelsLab, self-hosted images start at $0.0047 each, self-hosted video clips at $0.05 and text to speech at $0.001 per second of audio. The $149/month Open Source Unlimited plan removes the per-generation charge on every self-hosted model. Prices checked September 2026.

$0.0047 per image on self-hosted models, on every plan. At 100,000 images a month on the $149 Open Source Unlimited plan the effective cost is about $0.0015 per image, because that plan has no per-image charge on self-hosted models.

On Basic and Standard, self-hosted clips cost $0.05 (SVD, CogVideoX), $0.075 (Wan 2.2, LTX-2.3) or $0.375 for a 5-second Wan 2.1 clip. They have no per-clip charge on the $149 plan. Partner models such as Kling, Veo and Seedance are priced per second. On Basic and Standard they use your plan's included usage first, then your wallet; on the $149 plan they bill from your wallet.

Text to speech costs $0.001 per second of generated audio, with a $0.0047 minimum per request. Speech to text (Whisper large-v3) costs $0.0047 per request. Both run on our own GPUs and have no per-request charge on the $149 plan. ElevenLabs and Inworld voices are partner models: on Basic and Standard they use your plan's included usage first, then your wallet.

When your self-hosted usage would cost more than $149 a month at list price: about 31,700 images at $0.0047, about 1,990 Wan 2.2 clips at $0.075, or about 41 hours of text to speech at $0.001 per second. Above that, more generations on self-hosted models cost nothing extra; the limit is 15 parallel generations.

No. The LLMs on ModelsLab run on partner providers and are billed per million tokens, from your plan's included usage first on Basic and Standard and from your wallet on the $149 plan. The flat-price advantage applies to the open-source image, video and speech models we host on our own GPUs.

ModelsLab is a paid service. Plans start at $21/month. Creating an account is free, but API calls require an active plan.
