)FREQUENTLY ASKED QUESTIONS
Everything developers ask before switching to a better OpenAI API alternative with unified LLM API access.
Is haimaker.ai a drop-in OpenAI API alternative?
Yes. haimaker.ai is fully compatible with the OpenAI SDK — just swap your base URL and API key. No code refactoring required. If your app already calls GPT-4, you can redirect it to 200+ models including Claude, Gemini, Mistral, and DeepSeek in minutes. It's the fastest way to explore any OpenAI API alternative without touching your existing codebase.
Which models and providers are available?
haimaker.ai provides unified LLM API access to 200+ models across all major providers: OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, Qwen, xAI, Cohere, Kimi, Microsoft, Databricks, and more. New models are added automatically — typically within hours of a provider's public release — so you're never blocked waiting for an integration.
How quickly are new models added?
New models are provisioned rapidly — usually the same day a provider makes them publicly available. You get automatic access through the same API endpoint you're already using. No re-deployment, no SDK updates, no waiting. New capabilities land in your app as fast as the providers release them.
How does pricing work? Are there hidden fees?
You pay only for the tokens you consume, billed at transparent per-model rates. There are no platform surcharges, no seat fees, and no minimum commitments. The pricing dashboard gives you real-time cost visibility across every model you call, so you can benchmark cost vs. performance and pick the right model for each use case.
What does 'Developer-First AI Gateway' actually mean?
It means the API is designed around how developers actually build — not around enterprise procurement cycles. You get a single REST endpoint, OpenAI-compatible request/response shapes, streaming support, and an API key you can start using in under two minutes. No sales call, no lengthy onboarding, no lock-in to a single model vendor.
Is my data secure? Do you store my prompts or completions?
haimaker.ai acts as a stateless gateway: your requests are proxied to the underlying provider without being logged, stored, or used for training. Traffic is encrypted in transit (TLS 1.3), and your API key is hashed at rest. You retain full ownership of your inputs and outputs at all times.
