Openrouter Free Responder

Use the bundled script to execute prompts against free OpenRouter models.

Workflow

1. Ensure OPENROUTER_API_KEY is set.
2. Run:

```bash

python3 {baseDir}/scripts/openrouter_free_chat.py --prompt ""

```

1. If the user provided system guidance, pass --system "...".
2. Return the response text and mention which model was used.

Command Options

• --prompt (required): User prompt text.
• --system (optional): System instruction.
• --max-attempts (optional, default 8): Number of top free models to try.
• --temperature (optional, default 0.3): Sampling temperature.
• --debug (optional): Print model ranking and fallback attempts to stderr.

Output Contract

The script prints one JSON object to stdout with:

• selected_model: Model that produced the final response.
• response: Final assistant text.
• attempted_models: Ordered list of tried models.
• free_model_candidates: Number of free models discovered.

If no model succeeds, the script exits non-zero with an error message.
