client = OpenAI(
    base_url="https://api.parasail.io/v1",
    api_key=os.environ["PARASAIL_API_KEY"],
)

chat_completion = client.chat.completions.create(
    model="parasail-deepseek-r1",
    messages=[{"role": "user", "content": "What is the capital of New York?"}]
)

print(chat_completion.choices[0].message.content)

4. List available models

curl https://api.parasail.io/v1/models \
