OpenRouter incompatible with new openai API

[jmizgajski]

following code yields a 404 on openai==1.3.5 which destroys compatibility with langchain and llama_index

client = OpenAI(
    default_headers={
        "HTTP-Referer": referer,
    },
    base_url="https://openrouter.ai/api/v1",
    api_key=open_router_key,
    max_retries = max_retries,
)
response = client.completions.create(
    prompt=prompt,
    model=self.model_name,
    max_tokens=self.max_tokens,
    temperature=self.temperature,
    n=self.n,
)
reply = response.choices[0].text

the request made looks like this in debugger - seems open-ai changed their endpoints
