FAQFrequently Asked Questions
Which AI models are free on Pixazo?
The free tier includes five production-ready models: Flux Schnell, Stable Diffusion 3.5, and SDXL for AI image generation, LTX for AI video generation, and Pixazo Tracks for AI music and song generation. All five ship on one Pixazo endpoint with one API key.
Do I need a credit card to use the free APIs?
No. You can sign up and start generating images and audio without providing any payment information. The free tier is active immediately upon account creation.
What can I generate on the free tier?
You can create images from text prompts (Flux Schnell, SD 3.5, SDXL), transform existing images (SD 3.5, SDXL), generate video from text or a still image (LTX), and produce music or songs from text prompts (Pixazo Tracks). All five models share one unified API and a single API key.
What are the rate limits on the free tier?
The free tier runs at a fair-use rate limit of 60 requests per minute, per model, during preview. Every free model — Flux Schnell, Stable Diffusion 3.5, SDXL, LTX and Pixazo Tracks — shares this quota shape, so you can prototype freely and only hit a wall on sustained load. Check your Pixazo dashboard for live usage. Upgrading unlocks higher limits + priority processing.
Can I use free-tier output commercially?
Usage rights depend on the specific model and Pixazo's terms of service. Review the terms for each model to understand what commercial use is permitted under the free tier.
What image and audio specs are supported on the free tier?
Flux Schnell and SDXL support up to 1024x1024 pixels. Stable Diffusion 1.5 supports up to 512x512 pixels. Pixazo Tracks generates MP3 clips for music and song use cases. Additional resolutions, durations, and formats are available on paid tiers.
How do I upgrade to a paid plan?
You can upgrade at any time from the Pixazo dashboard. Paid plans unlock additional image, video, and audio models, higher rate limits, priority processing, and more resolution and duration options.
What programming languages are supported?
The Pixazo API is a standard REST API and works with any language that can make HTTP requests — Python, JavaScript, Go, Ruby, PHP and others. The docs include code samples for the most common stacks.
What is the best free AI image generation API?
Pixazo's free AI image generation APIs cover three complementary models: Flux Schnell for the fastest generation, Stable Diffusion 3.5 as the flagship versatile option for text-to-image and image-to-image, and SDXL for the highest resolution on the free tier at 1024x1024. All three ship on one Pixazo endpoint with a single API key and no credit card.
Which free AI video generation API supports text-to-video?
LTX by Lightricks is the free AI video generation API on Pixazo — supporting text-to-video, image-to-video, and video-to-video workflows all on the free tier. It runs on the same REST endpoint pattern as the free image and audio models, so you only manage one API key.
What can I generate with the free AI audio generation API?
Pixazo Tracks — the free AI audio generation API — turns a single text prompt into either an instrumental track or a full song with vocals, delivered as an MP3. It runs on the same free-tier fair-use quota (60 requests per minute) as the free image and video APIs.
