Since Routstr proxies to OpenRouter.ai, the available models depend on what OpenRouter.ai offers. The models listed above are examples and may not represent the current available models.

​
Pricing

Each model has different pricing for input tokens (prompt) and output tokens (completion). The pricing is shown in dollars per 1,000 tokens. For example, GPT-4 costs 0.03per1,000inputtokensand0.03 per 1,000 input tokens and 0.06 per 1,000 output tokens.
