Vercel AI Gateway
Route calls to hundreds of model providers through a single Vercel API key.
Vercel AI Gateway is the default LLM provider in Scira. It's a unified proxy that gives access to models from Anthropic, OpenAI, Google, DeepSeek, xAI, and others — all through one key, with built-in caching, load balancing, and usage monitoring.
Get a key
Sign in to Vercel
Go to vercel.com and sign in. The free tier is enough to get started.
Open AI Gateway
From your team dashboard, navigate to AI Gateway in the sidebar.
Create an API key
Under API Keys, click Create Key. The key starts with sk-. Copy it now — it is only shown once.
Add the key to Scira
scira init
# or manually:
echo "AI_GATEWAY_API_KEY=sk-..." >> ~/.scira/.envConfigure
{
"llmProvider": "gateway",
"model": "deepseek/deepseek-v4-flash"
}Switch to this provider from the TUI with /llm → Vercel AI Gateway.
Choosing a model
Run /model in the TUI to open the live picker — it fetches the current list from the gateway and filters to models that declare tool-use support. The full browsable catalog is at vercel.com/ai-gateway/models.
Notable models available as of June 2026:
| Model ID | Notes |
|---|---|
deepseek/deepseek-v4-flash | Default. Most popular on the gateway, fast and cheap |
deepseek/deepseek-v4-pro | DeepSeek's top-tier V4 model — 1M context, complex reasoning |
anthropic/claude-fable-5 | Claude Fable 5, Anthropic's latest long-context model |
anthropic/claude-sonnet-4-6 | Strong reasoning, high quality |
openai/gpt-5.5 | OpenAI's current flagship |
google/gemini-2.5-flash | Google fast-tier Gemini |
xai/grok-4.3 | xAI Grok via gateway (no separate XAI key needed) |
The live list from /model is authoritative — the table above is a snapshot.
Pricing
Vercel AI Gateway bills at pass-through rates from the underlying provider — no extra gateway fee on the free tier. See vercel.com/docs/ai-gateway for current details.
