DeepSeek V4.1 Flash now available on AI Gateway
DeepSeek V4.1 Flash lands on Vercel's AI Gateway with vision — another model option for agent builders.
Why it matters
DeepSeek's fast multimodal model is now accessible through a unified API layer (Vercel's AI Gateway), lowering friction for practitioners building with multiple models. Vision support + 1M context + agent-framework integration (Cursor, Claude Code) makes this a practical addition to the toolkit, not just a model release.
