Why MegaBrain?

Built differently,
on purpose.

AI inference tools should work for you, not against you.

AI EFFECTIVENESS

MODEL INDEPENDENCE

Switch models
without changing code

One API endpoint covers every provider. Claude, GPT-4o, Llama, Gemini, DeepSeek — change one string and you're running a different model.

  • OpenAI-compatible SDK drop-in
  • 500+ models, one base URL
  • No migration cost when providers change pricing
How it works →
01

Model Independence

No single model wins on every dimension. MegaBrain routes each request to the best model for the task — so you always get the highest score without paying for it across the board.

  • Best coding score without overpaying for reasoning
  • Fastest model when speed matters, smartest when it doesn't
  • Switch models in one line — no migration

Stop choosing models.
Start shipping.

Pick Frontier, Balanced, or Free. Auto Model handles the routing behind the scenes, using the right model strategy for your budget and the work at hand.

Frontier

Routes to the latest, most capable paid models for the hardest tasks — stronger reasoning for planning and analysis, best-fit models for everything else.

Balanced

Routes to a cost-effective paid model selected for the interface in use. The best default when you want capable results without frontier prices.

Free

Routes to the best available free models and splits traffic across them. The mapping updates server-side as free-model availability changes.

Industries

Built for industries that need AI the most — and can't afford to vibe code.

Production-grade software delivery where quality, security, and compliance are non-negotiable.

Enterprise

Full usage analytics per team, per engineer. See who is shipping with AI and who needs enablement.

Financial Services

Secure, auditable AI workflows. Model usage logged and attributable for compliance reporting.

Frequently asked questions

What is MegaBrain Gateway?+

A universal routing layer for AI inference. Send a request to one OpenAI-compatible endpoint and we route it to the right model across 500+ models from 60+ providers, with no markup on token costs.

How does cost visibility work?+

Every request is logged with model, token counts, and cost at the exact provider rate. You see per-user and per-team breakdowns in the dashboard — so you know where the budget is going before it becomes a problem.

Which coding agents are supported?+

Any agent that supports a custom OpenAI-compatible base URL works with MegaBrain: Claude Code, Codex CLI, Cursor, Cline, OpenCode, Hermes, KiloClaw, Windsurf, and more. See our cookbook docs for setup guides.

Do I need a subscription?+

No. Start free with free models, then pay pay-as-you-go at exact provider rates. No monthly lock-in.

How does Auto Model choose a model?+

You pick a tier — Frontier, Balanced, or Free — and Auto Model routes each request through the model strategy that matches your capability and cost preference.

Can I bring my own provider keys?+

Yes. Plug in your existing Anthropic, OpenAI, Google or other provider API keys. Pay for the routing, not the tokens.
