Fal AI

The robomotion falai CLI runs AI models hosted on Fal.ai for image generation, video generation, text-to-speech, and other ML tasks. It supports both synchronous execution (wait for result) and async queue-based workflows (submit, poll status, retrieve result).

When to use

• Generate images (Flux, SDXL, etc.) via Fal.ai
• Run video or audio generation models
• Submit long-running AI jobs to a queue and poll for results
• Cancel or check status of queued inference requests

Prerequisites

• robomotion CLI installed
• Package installed: robomotion install falai
• Fal.ai API key configured via Robomotion vault

IMPORTANT: Session Mode Required for Multi-Step Operations

Each CLI command runs as a separate process — connection IDs from connect do NOT persist across calls. You MUST use --session on connect and pass --session-id to all subsequent commands.

Workflow

1. Install (once): robomotion install falai
2. Connect with session:

   robomotion falai falai_connect --session --output json
   # → {"outClientId":"<client-id>","session_id":"<session-id>"}
   

3. Use the returned client-id and session-id in all subsequent commands:

   robomotion falai falai_run_model --client-id "<client-id>" --model-id <model> --input <json> --session-id "<session-id>" --output json
   

4. Disconnect when done:

   robomotion falai falai_disconnect --client-id "<client-id>" --session-id "<session-id>" --output json
   

Always append --output json to get structured JSON results.

Commands Reference

• robomotion falai falai_connect --session --output json Connects to Fal.ai API and returns a client ID for subsequent nodes
• robomotion falai falai_disconnect --client-id --session-id "<session-id>" --output json Closes the Fal.ai connection and releases resources
• robomotion falai falai_run_model --client-id --model-id --input [--300] [--mode] --session-id "<session-id>" --output json Runs an AI model on Fal.ai and waits for the result. Supports any model (image generation，video generation，TTS，etc.)
• robomotion falai falai_submit_request --client-id --model-id --input [--webhook-url] --session-id "<session-id>" --output json Submits a request to the Fal.ai queue and returns immediately with a request ID for async tracking
• robomotion falai falai_get_status --client-id --model-id --request-id --session-id "<session-id>" --output json Checks the status of a queued Fal.ai request
• robomotion falai falai_get_result --client-id --model-id --request-id --session-id "<session-id>" --output json Retrieves the result of a completed Fal.ai request
• robomotion falai falai_cancel_request --client-id --model-id --request-id --session-id "<session-id>" --output json Cancels a queued Fal.ai request

Environment

• ROBOMOTION_API_TOKEN (if vault credentials are needed)
