Mistral Codestral

Mistral & Codestral — Mistral AI Models on Your Local Fleet

Mistral AI's open-source models run locally on your hardware. Mistral Large for frontier reasoning, Mistral-Nemo for efficiency, Codestral for code generation. The fleet router picks the best device for every Mistral request.

Supported Mistral models

Setup Mistral locally

pip install ollama-herd    # install Mistral fleet router
herd                       # start the Mistral-compatible router
herd-node                  # run on each device — Mistral requests route automatically

No Mistral models downloaded during installation. All Mistral model pulls are user-initiated.

Codestral code generation

Codestral is Mistral AI's dedicated coding model — trained on 80+ programming languages with fill-in-the-middle support.

from openai import OpenAI

# Connect to local Mistral fleet
mistral_fleet = OpenAI(base_url="http://localhost:11435/v1", api_key="not-needed")

# Codestral by Mistral for code generation
codestral_response = mistral_fleet.chat.completions.create(
    model="codestral",  # Mistral's Codestral model
    messages=[{"role": "user", "content": "Write a Redis-backed rate limiter in Go"}],
)
print(codestral_response.choices[0].message.content)

Codestral via curl

# Codestral code generation on local Mistral fleet
curl http://localhost:11435/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"model": "codestral", "messages": [{"role": "user", "content": "Implement a B-tree in Rust — Mistral Codestral excels at systems programming"}]}'

Mistral Large reasoning

# Mistral Large for complex reasoning
curl http://localhost:11435/api/chat -d '{
  "model": "mistral-large",
  "messages": [{"role": "user", "content": "Compare Mistral vs GPT-4 for enterprise deployments"}],
  "stream": false

Mistral hardware recommendations

Cross-platform: These are example configurations. Any device (Mac, Linux, Windows) with equivalent RAM works. The fleet router runs on all platforms.
