Free Worker Dispatch

Delegate tasks to free AI models via OpenRouter. Save your expensive primary model for strategy and quality review — let free models handle the grunt work.

Why This Exists

Running everything through Claude Opus or GPT-4 costs real money. Free models on OpenRouter handle most content, research, and coding tasks perfectly well. This skill routes tasks intelligently, saving agents from surprise bills.

Available Free Models

| Model | Best For | Context | |-------|----------|---------| | stepfun/step-3.5-flash:free | Research, analysis, brainstorming | 128K | | arcee-ai/trinity-large-preview:free | SEO copy, blog posts, marketing | 128K | | openrouter/free | Auto-route to best available free model | Varies |

Commands

Dispatch a task to a free model

python3 {baseDir}/scripts/dispatch.py task --prompt "Write a blog post about freelance copywriting rates in 2026" --model "arcee-ai/trinity-large-preview:free"

Dispatch with auto-model selection

python3 {baseDir}/scripts/dispatch.py task --prompt "Research the top 10 Notion templates for freelancers" --type research

List available free models

python3 {baseDir}/scripts/dispatch.py models

Check model status (is it up?)

python3 {baseDir}/scripts/dispatch.py status --model "stepfun/step-3.5-flash:free"

Dispatch with output to file

python3 {baseDir}/scripts/dispatch.py task --prompt "Write an email newsletter about AI tools" --type content --output newsletter-draft.md

Batch dispatch (multiple tasks)

python3 {baseDir}/scripts/dispatch.py batch --file tasks.json

The tasks.json format:

[
  {"prompt": "Write a product description", "type": "content"},
  {"prompt": "Research competitor pricing", "type": "research"},
  {"prompt": "Generate a Python script for...", "type": "code"}
]

Task Types

The --type flag auto-selects the best free model:

| Type | Model | Why | |------|-------|-----| | research | stepfun/step-3.5-flash:free | Fast, good at analysis | | content | arcee-ai/trinity-large-preview:free | Strong at writing | | code | openrouter/free | Auto-routes to best coder | | general | openrouter/free | Let OpenRouter decide |

Output

Results are printed to stdout by default. Use --output to save to a file. Use --json for structured JSON output including model used, tokens, and timing.

Tips

Always review worker output before publishing — free models hallucinate

Use --type for best model matching instead of specifying models directly

Batch dispatch is faster for multiple independent tasks

If a model is down, the script falls back to openrouter/free
