The multi-model LLM API

One prompt. Every model.
The best answer.

Run the same prompt through GPT, Claude, Gemini, and more — simultaneously. Compare the outputs, blend the best parts, or let AI judge which model wins. All from one API call.

Not just routing. Orchestration.

Every mode is one POST request with real-time SSE streaming. Reliability is a toggle on Chat via failover routing.

See which model is best — on YOUR prompt

Same prompt hits 2-9 models simultaneously. Responses stream back in real-time with per-model latency, token counts, and cost.

Keep your integration, improve your routing

  1. Keep your prompts and messages (role + content).
  2. Swap your client to the LLMWise SDK and set your API key.
  3. Set cost/latency/reliability policy guardrails.
  4. Run replay lab against recent requests before rollout.
  5. Turn on failover routing for outage protection.

Frequently asked questions

How is LLMWise different from OpenRouter?

+

OpenRouter routes requests to models. LLMWise orchestrates — compare models side-by-side, blend outputs from multiple models, let AI judge AI, and auto-failover with circuit breakers. All through one API.

Is the API OpenAI-compatible?

+

LLMWise uses the familiar role/content message format, but it’s a native API with its own endpoints and streaming event shape. For the easiest integration, use the official LLMWise SDKs (Python/TypeScript) or call /api/v1/chat directly.

What models does LLMWise support?

+

We currently support 31 models across 16 providers, including GPT, Claude, Gemini, DeepSeek, Llama, Mistral, Grok, and free-model options. Auto mode picks the best model path for each request.

How do credits work?

+

Each mode costs fixed credits per request: Chat 1, Compare 3, Blend 4, Judge 5, and Failover 1. You start with 40 free trial credits (7 days), then continue with credit-based pay-per-use. Paid credits do not expire.

How do I keep cost low automatically?

+

Use Cost saver in Chat mode. It sets model=auto with optimization_goal=cost so simple prompts route to lower-cost capable models. You can enable it in dashboard chat or send cost_saver=true in /api/v1/chat.

Can I bring my own API keys (BYOK)?

+

Yes. Add your OpenAI, Anthropic, Google, or other provider keys in Settings. When a BYOK key is active for a provider, usage for those requests is billed to your provider account instead of your LLMWise wallet credits.

Do I need separate accounts with each AI provider?

+

No. LLMWise gives you access to 31 models across 16 providers through one API key, so you can start without managing separate subscriptions.

Do I need ChatGPT Plus, Claude Pro, and Gemini subscriptions?

+

No. You can start with LLMWise credits and use multiple models from one account. BYOK is optional if you want to plug in your own provider contracts later.

What happens if a model goes down?

+

Turn on Failover. It automatically routes to your backup chain when a model returns 429, 500, or times out. Circuit breakers detect unhealthy models and skip them proactively. Same 1 credit cost.

Is there a free tier?

+

Yes. Sign up and get 40 free trial credits (7 days). No credit card required. After trial, paid credits are pay-per-use and do not expire.
