Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family.
It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.
Use your team's private packages or design system in v0 with one shared npm credential.
Set 𝙽𝙿𝙼_𝚃𝙾𝙺𝙴𝙽 or 𝙽𝙿𝙼_𝚁𝙲 once as a sensitive shared environment variable on Vercel. The credential is injected at the network layer. The model and agent never see it.

v0 is now model-agnostic.
Frontier models, cheap models, open models, and fast models, all from Vercel's AI Gateway.
Choose from Claude, GPT, Kimi, GLM, Grok, DeepSeek and more to build your apps.
It's all Vercel: the integrations you use on Vercel are coming directly to v0.
To start, Resend, Amazon OpenSearch, MongoDB Atlas, Algolia, and Clerk are now one click from the chat. Auto-setup, skills loaded. Build without leaving v0.
For everyone who asked me in DMs: I used @v0 by Vercel
