How do I call Mistral Small 4?
With the OpenAI SDK, as for any OpenAI-compatible API: set the base URL to https://llmwithcrypto.com/api/v1, read your key from LLMWITHCRYPTO_API_KEY, and pass mistral-small-4 as the model. Pass your API key as a Bearer token in the Authorization header, as the OpenAI SDK does.
import os
from openai import OpenAI
client = OpenAI(
base_url="https://llmwithcrypto.com/api/v1",
api_key=os.environ["LLMWITHCRYPTO_API_KEY"],
)
resp = client.chat.completions.create(
model="mistral-small-4",
messages=[{"role": "user", "content": "Tag each of these five product reviews as positive, negative or mixed."}],
)
print(resp.choices[0].message.content)
print(resp.usage) # prompt_tokens and completion_tokens: what the call costs
What is Mistral Small 4 good for?
Mistral Small 4 (2603) is Mistral AI’s small open model, Apache 2.0, with a context of about 256K tokens. Like Large 3, it was listed only on Mistral’s own API when we read the host pages.
It suits quick, inexpensive calls: tagging, routing, short replies and extraction. For harder tasks, move up to Mistral Large 3 by changing the model id.
What licence does Mistral Small 4 come with?
Apache 2.0, per Mistral’s documentation and Hugging Face. Hosting it as an API is allowed. Each model keeps its own licence and use policy (for example Meta’s Llama Acceptable Use Policy and the “Built with Llama” notice); using a model through us means accepting them.
