How to migrate off open-codestral-mamba

grep -rn --exclude-dir={node_modules,.git,dist} "open-codestral-mamba" .

Replace the model ID:

- model: "open-codestral-mamba"
+ model: "Codestral"

Re-run your evals or a sample of real prompts — output style, token usage and pricing can change between models.
