Ling 3.1 Flash is now available on AI Gateway
Ling 3.1 Flash—560B hybrid reasoning model—is free on Vercel's AI Gateway through October 2026.

Why it matters
A new hybrid reasoning model lands on a routing/cost-tracking platform, expanding model choice for developers building agents and code workflows. Free tier through mid-2026 lowers adoption friction; transition to paid afterward creates budget implications for teams scaling beyond the promotion.
