One assistant across every device, the right model chosen for you, spending you actually control, and a clean API when you want to build on it.
The same DrLarz follows you across screens — speak to it or type, whenever and wherever it's easiest.
Talk to DrLarz hands-free or type — natural back-and-forth either way.
One assistant on the device in your hand and the one on your desk.
Drop DrLarz into your own product so your users get the same assistant.
Ask for fast or ask for deep — DrLarz routes to the right engine automatically. The backend is invisible, and it's never just one provider.
The flagship all-rounder. Best balance of quality and speed for everyday work.
Optimised for speed. For quick answers and snappy streaming.
Code generation, refactoring and debugging, tuned for technical accuracy.
Hard problems that need long thinking. Slower, but the deepest reasoning.
Most services email an alert after you've spent the money. DrLarz refuses the request before it costs you anything.
"Stop at $50 today" means stop. The cap is enforced the moment it's hit.
Get notified at 50%, 75% and 90% of your budget. Spot trouble early.
Different limits for different surfaces — prod, dev, that side project.
One balance, per-key and per-day usage, no surprise invoices.
Use the OpenAI- or Anthropic-compatible API you already know. Point your SDK at DrLarz, use a DrLarz model name, and we handle everything behind it.
The OpenAI Python and JS SDKs work as-is. Just change the base URL.
Anthropic-style calls work too — no need for a different client per format.
Server-sent events and function calling, the same shape you already expect.
