Pricing Details
GoogleOpen-weight (Apache 2.0). Dense 30.7B params. Native reasoning mode, vision, video. Google publishes no per-token rate for Gemma on ai.google.dev/gemini-api/docs/pricing — the weights are free and the figure here is a third-party host's rate via OpenRouter, so it can never be stamped against a Google page and moves with whoever is serving it. Flagged unverified on August 24, 2026 for the same reason the gpt-oss rows are.
