From seed to symphony: Svivva turns plain-language intent into shipped product — with validation, evaluations, versioning, and rollback so quality does not drift.

How long does it take to ship with Svivva?

Most teams get a working, tested endpoint live quickly. Describe what you need, define the output schema, deploy — Svivva handles validation, rollback, and ops.

Does Svivva work with OpenAI and other AI models?

Yes. Svivva supports OpenAI (GPT-4o, GPT-4, GPT-3.5), Anthropic Claude, Google Gemini, and other LLMs. You can route between models automatically based on cost or quality thresholds.

Do I need to write code to use Svivva?

No. Svivva's core workflow is entirely no-code — describe your API in plain English, set your output schema, and deploy. A TypeScript SDK is available for developers who want programmatic access.

Is Svivva free to start?

Yes. Svivva has a free tier with no credit card required. Paid plans start at $49/month and unlock unlimited endpoints, higher request volumes, and team features.

What happens if my endpoint returns bad data?

Svivva validates every response against your JSON schema and automatically retries or repairs malformed outputs. If quality drops below your threshold, auto-rollback reverts to the last good version.

Frequently Asked Questions

Do I need an API key to use PromptForge?

No — PromptForge is completely free to use. No signup, no API key, no credit card. It's powered by Svivva's infrastructure.

Which models are available?

GPT-4o mini (fast and cheap, great for most tasks), GPT-4o (smarter, best quality), and GPT-4 Turbo (powerful, long context). More models coming soon.

What does temperature do?

Temperature controls randomness. 0 = deterministic, precise answers. 2 = highly creative and varied. For factual tasks use 0–0.3. For creative tasks use 0.7–1.2.

How do I deploy my prompt to production?

Once you're happy with your prompt, Svivva lets you deploy it as a live API endpoint in one click — with rate limiting, schema validation, and usage analytics built in.

Is there a rate limit?

Free use is limited to 12 requests per minute per IP. For unlimited usage, sign up for Svivva.
