Use when you need Groq to behave differently across dev, staging, and production — cheap fast models and verbose logs in dev, the production model and hardened retries everywhere else, with per-environment API keys. Configure environment-specific model selection, rate limits, and secrets. Trigger with phrases like "groq environments", "groq staging", "groq dev prod", "groq environment setup", "groq multi-env", "groq config by env".
