# OATDA Compare Models Send one prompt to multiple LLM providers in a single parallel request and get back each model's response. Perfect for benchmarking, picking the best model for a task, or evaluating quality / speed / cost tradeoffs. ## When to Use Use this skill when the user wants to: - Compare outputs from 2+ LLM models side-by-side - Benchmark models on a specific prompt - Pick the best model for a particular task before committing to one - See how different providers (OpenAI, Anthropic, Google, DeepSeek, etc.) handle the same input ## Prerequisites The user needs an OATDA API key. Check in this order: 1. `$OATDA_API_KEY` environment variable 2. `~/.oatda/credentials.json` config file If neither exists, tell the user: > You need an OATDA API key. Get one at https://oatda.com, then set it: > `export OATDA_API_KEY=your_key_here` ## Step-by-Step Instructions ### 1. Resolve the API key ```bash # Check env var first; if empty, auto-load from credentials file if [[ -z "$OATDA_API_KEY" ]]; then export OATDA_API_KEY=$(cat ~/.oatda/credentials.json 2>/dev/null | jq -r '.profiles[.defaultProfile].apiKey' 2>/dev/null) fi # Verify key exists (show first 8 chars only) echo "${OATDA_API_KEY:0:8}" ``` If the output is empty or `null`, stop and ask the user to configure their API key. **IMPORTANT**: - Never print the full API key. Only show the first 8 characters for verification. - The key resolution script and subsequent `curl` commands **must run in the same shell s
