title: Chat Mistral
description: Run Mistral open and frontier models for text generation.
---

Give an AI node access to Mistral AI's open and frontier models, using your own Mistral API key.

Pick a saved connection in the **Authentication** field, or create one from there.

## What it does

Chat Mistral is a model you plug into the **Model** slot of an AI node, such as the [Tools Agent](/nodes/builtin/ai/aiagents/toolsagentnode/) or [Basic LLM Chain](/nodes/builtin/ai/aiagents/basicllmchainnode/). It does not run on its own and has no output. When the AI node runs, it sends its messages to Mistral with your key and gets the reply back.

* **Temperature** is 0 when you leave it empty, so answers are focused and repeatable.
* Replies are capped at **Max Tokens** (4096 by default).
* A failed request is retried up to **Max Retries** times (2 by default). A request that gets no answer within 60 seconds fails.

## When to use it

* You prefer a European AI provider.
* Writing and translating text in a workflow with your Mistral account.
* A small, cheap model for simple jobs and a large one for harder ones, from the same provider.

## Inputs and settings

Type the **Model** id as Mistral names it, for example `mistral-large-latest` or `mistral-small-latest`. The `-latest` ids always point to the newest version.

## Outputs

This node has no output port. It plugs into a slot on another node instead of passing items along.

* **Model** slot of [Tools Agent](/nodes/builtin/ai/aiagents/toolsagentnode/), [Q\&A Agent](/nodes/builtin/ai/aiagents/qanode/), [RAG Agent](/nodes/builtin/ai/aiagents/ragnode/), [Basic LLM Chain](/nodes/builtin/ai/aiagents/basicllmchainnode/), [Indexer](/nodes/builtin/ai/aiagents/indexernode/), [Text Classifier](/nodes/builtin/ai/aiagents/textclassifiernode/), [Sentiment Analysis](/nodes/builtin/ai/aiagents/sentimentanalysisnode/), [Summarization](/nodes/builtin/ai/aiagents/summarizationchainnode/), [Information Extractor](/nodes/builtin/ai/aiagents/informationextractornode/), [Guardrails](/nodes/builtin/ai/aiagents/guardrails/), [Auto-fixing Output Parser](/nodes/builtin/ai/aidependencies/outputparser/autofixingoutputparser/)

The AI node you connect it to produces the output. Chat Mistral only decides which model answers.

## Dependencies and credentials

* **Authentication** (connection): required. See [Connect Mistral](/app/connections/mistral/).

In **Authentication**, use a Bearer Token credential that holds your Mistral API key. Create the key on the API Keys page of the Mistral console (La Plateforme). See [Create a credential](/app/connections/create/).

## Example workflow

1. A [Context Menu](/nodes/builtin/trigger/contextmenu/) trigger on selected text.
2. [Basic LLM Chain](/nodes/builtin/ai/aiagents/basicllmchainnode/) with **Prompt** `Translate into French, keep the tone: {{ $input.selectionText }}`.
3. Chat Mistral in its **Model** slot, **Model** `mistral-small-latest`.
4. [Clipboard Write](/nodes/extension/clipboardwrite/) with **Text** `{{ $input.response }}`.

## Common issues

* **"Model parameter is required and cannot be empty".** Fill in **Model**.
* **A 401 error.** The key is wrong or revoked. Create a new key and update the credential.
* **A 429 error.** You hit your plan's rate limit. Send fewer items at once, or upgrade the plan.
* **An "invalid model" error.** The model id is misspelled. Copy it from Mistral's model list.

## Related nodes

* [Basic LLM Chain](/nodes/builtin/ai/aiagents/basicllmchainnode/): send one prompt and get a reply.
* [Tools Agent](/nodes/builtin/ai/aiagents/toolsagentnode/): an agent that can use tools and memory.
* [Translate](/nodes/builtin/ai/localai/translate/): translate on your device, without a key.
