Mistral AI Core Workflow A: Chat Completions

Overview

Production chat completion patterns for Mistral AI: multi-turn conversations, streaming responses, JSON mode structured output, guardrails/moderation, and model selection. Uses the @mistralai/mistralai SDK.

Prerequisites

• Completed mistral-install-auth setup
• MISTRAL_API_KEY environment variable set
• Understanding of Mistral model tiers

Instructions

Step 1: Basic Chat Completion

import { Mistral } from '@mistralai/mistralai';

const client = new Mistral({ apiKey: process.env.MISTRAL_API_KEY });

async function chat(userMessage: string): Promise<string> {
  const response = await client.chat.complete({
    model: 'mistral-small-latest',
    messages: [
      { role: 'system', content: 'You are a helpful assistant.' },
      { role: 'user', content: userMessage },
    ],
  });
  return response.choices?.[0]?.message?.content ?? '';
}

Step 2: Multi-Turn Conversation Manager

  {
  :  |  | ;
  : ;
}

  {
   : [] = [];
   : ;
   : ;

  () {
    . =  ({ : process.. });
    . = model;
    ..({ : , : systemPrompt });
  }

   (: ): <> {
    ..({ : , : userMessage });

     response =  ...({
      : .,
      : .,
    });

     reply = response.?.[]?.?. ?? ;
    ..({ : , : reply });
     reply;
  }

  
  (maxTurns = ):  {
     system = .[];
     recent = ..().(-maxTurns * );
    . = [system, ...recent];
  }
}
