Multi-Modal Pipeline

Chain image + voice + music in one call

Define a multi-step pipeline that chains image, voice, video, and music generation in a single API call. Each step's output feeds the next. Cost is the sum of all steps, shown upfront. No competitor offers unified multi-modal pipelines.

$0.5004 per run

1 × $0.048/image (Nano Banana 2, 1K, key image) = $0.048 + 300 chars × $0.108/1K chars (ElevenLabs TTS Turbo 2.5, voice line) = $0.0324 + 5 s × $0.084/s (Kling 2.5 Turbo Pro I2V, animated shot) = $0.42 → $0.5004

Base model cost + a flat 20% platform fee, shown before you spend.

How Multi-Modal Pipeline Works

Multi-Modal Pipeline lets you define a sequence of AI generation steps that execute automatically, with each step's output feeding into the next. For example: generate an image from a prompt, convert it to a video clip, synthesize a voiceover, and combine them -- all in one API call. The pipeline engine manages model orchestration, intermediate file storage, and error handling. You define the steps; the system handles the execution. Developers building content creation platforms, marketing automation tools, and AI-powered creative suites use pipelines to offer complex generation workflows through a simple interface. A marketing platform can generate a complete social media video (image + motion + voice + music) from a single brief. A children's app can produce illustrated stories with narration. No competitor currently offers a unified multi-modal pipeline API that spans image, video, voice, and music generation. Design pipelines with the minimum number of steps needed for your output. Each step adds latency and cost. Use the cost estimate endpoint on your pipeline definition to see the total price before running it. Include error handling configuration for each step -- specify whether a step failure should abort the pipeline or use a fallback. All intermediate outputs are accessible via their own URLs for debugging and reuse.

Cost Comparison

No competitor offers unified multi-modal batch API. Replicate, fal.ai, and RunPod are single-model services.

Frequently asked questions

Do I need a subscription to use Multi-Modal Pipeline?
No. FairStack uses pay-per-use pricing. Add funds to your account and use any tool whenever you need it. There is no subscription, no monthly commitment, and no minimum spend.
What file formats does Multi-Modal Pipeline support?
Multi-Modal Pipeline outputs MP4. You can download results instantly after generation. All outputs are full quality with no watermarks.
How long does Multi-Modal Pipeline take?
Most generations complete in 15-60 seconds depending on duration and resolution. Processing time depends on the complexity of your input and the selected quality settings. You can monitor progress in real time.
Can I use Multi-Modal Pipeline outputs commercially?
Yes. All outputs generated on FairStack include a commercial-use license. You can use them in client work, products, marketing materials, social media, and any other commercial context.
What output formats does the pipeline produce?
The final output format depends on the last step in your pipeline. Image steps produce PNG, video steps produce MP4, audio steps produce MP3. All intermediate outputs are also saved and accessible via their CDN URLs. The final response includes URLs for every step's output.
Can I use pipeline outputs commercially?
Yes. All outputs from every step in the pipeline are fully licensed for commercial use. The same commercial rights that apply to individual generations apply to pipeline outputs. No additional licensing fees.
What are the limits on pipeline complexity and concurrency?
A single pipeline can contain up to 10 sequential steps. There is no limit on the number of pipelines you can submit. Pipelines execute asynchronously and return results via webhook. Total cost is the sum of all step costs, shown upfront via the cost estimate endpoint before execution.
