Heads up. Source post said free for a week; the official OpenRouter page lists $0 pricing with no end date. Uses the Decisions API, not chat completions. Free preview models can be rate-limited or removed without notice. Separate from Parallel's own API free tier (up to 5,000 requests a month on parallel.ai).
