Description
Open weights ran 56% of Vercel AI Gateway tokens for 14% of the spend (FT, Aug 2026). Flagship pricing is in freefall — GPT-6.1 Sol at one-fifth of Astra (OpenAI, Sep 29), Gemini 4 Argon promo at $2/$10 (DeepMind, Sep 30) — while Anthropic unwinds ~15% enterprise volume discounts (The Information, Oct 2). OpenArb is a one-time audit kit that answers one question: how much of your agent spend could move to open weights, and what's the plan?
