Key differences from OpenAI Direct API

1

LLMWise provides access to 30+ models across OpenAI, Anthropic, Google, Meta, xAI, and DeepSeek through one API, whereas the OpenAI API only gives you OpenAI's own models.

2

Auto-routing in LLMWise analyzes your query and routes to the most cost-effective capable model, saving 30-40% compared to always using GPT-5 for every request.

3

Built-in mesh failover means your application stays up when OpenAI has outages — LLMWise automatically reroutes to Claude, Gemini, or another provider with zero downtime.

How to migrate from OpenAI Direct API

  1. 1Export your current OpenAI configuration: note which models, endpoints, and parameters you use. Save any custom system prompts or function schemas.
  2. 2Sign up for LLMWise and generate your API key. Optionally add your OpenAI key as a BYOK key to route directly to OpenAI at your own billing rate.
  3. 3Swap your OpenAI base URL to the LLMWise API endpoint. Your role/content message format works as-is — update the model parameter to a LLMWise model ID.
  4. 4Enable failover routing and auto-optimization. Run Compare mode on your critical prompts to discover whether Claude or Gemini outperforms GPT for specific tasks.
Example API request
POST /api/v1/chat
{
  "model": "auto",
  "optimization_goal": "cost",
  "messages": [{"role": "user", "content": "..." }],
  "stream": true
}

Common questions

Can I keep using OpenAI models through LLMWise?
Yes. LLMWise routes to OpenAI models (GPT-5.2, GPT-4.1, etc.) through its API. You can also bring your own OpenAI API key (BYOK) to use your existing billing relationship while gaining failover and orchestration features.
How does pricing compare to the OpenAI API directly?
LLMWise uses credit-based pricing with usage settlement. For equivalent GPT requests, costs are comparable. The savings come from auto-routing: simple queries go to cheaper models automatically, reducing your average cost by 30-40% without quality loss.
Does LLMWise support BYOK with my OpenAI key?
Yes. Add your OpenAI API key in the LLMWise dashboard and requests for OpenAI models route directly to OpenAI on your billing. You still get LLMWise failover, orchestration, and analytics.
How long does migration take?
Most teams migrate in under an hour. Since LLMWise accepts the same role/content message format, you only need to change the base URL and API key. No prompt rewriting required.
What happens when OpenAI is down?
LLMWise mesh routing detects OpenAI failures and automatically reroutes to Claude, Gemini, or another capable model. Your application stays up with no code changes needed.
