2. Define Provider: Choose Vercel AI Gateway from the registry.
3. Insert Credentials: Paste your Vercel API key into the designated field.
4. Assign Primary Engine: Select your intended model from the dropdown.

Strategic Operational Features

• Automatic Prompt Caching: Sypha leverages Vercel's caching layer (for models like Claude and GPT-4) to significantly reduce token expenditure on recurring prompts.
• BYOK (Bring Your Own Key): Utilise Vercel’s infrastructure with your own provider keys for zero platform markup.
• Governance & Monitoring: Track every interaction and set hard budgets at the gateway level to prevent cost overruns.
• Zero Rate Limits: Vercel does not impose additional rate limiting, allowing you to operate at the maximum capacity of your upstream providers.
