Repository: mistralai/cli

Tag: cli/v0.4.0

Published: 2026-08-27T12:56:04Z

Prerelease: no

Release notes:

Added

• mistral evals optimize — turn an existing eval file into an optimization

run that searches for better prompts and parameters (v0; optimizes .py eval files). Optional flags:

• --params — comma-separated params to optimize (e.g. instruction,temperature:0..1);

defaults to all System.params.

• --steer — a free-text goal that steers the optimizer's reflective mutator

(e.g. "reduce hallucinations when the context lacks the answer"), max 4000 chars.

• --name / --description — human-friendly metadata for the optimization;

auto-generated from the goal when omitted.

• Install via plain curl, with optional version pinning.

Fixed

• apps init checks that bun is on PATH before shelling out to it, failing with

a clear error instead of crashing.
