Mistral SDK Patterns
Overview
Production-ready patterns for the Mistral AI SDK. Covers singleton client, retry/backoff, structured output, streaming, function calling, batch embeddings, and async Python — all with proper error handling. SDK is ESM-only for TypeScript (@mistralai/mistralai), sync+async for Python (mistralai).
Prerequisites
@mistralai/mistralai (TypeScript) or mistralai (Python) installedMISTRAL_API_KEY environment variable set
Instructions
Step 1: Singleton Client with Configuration
TypeScript
import { Mistral } from '@mistralai/mistralai' ;
let _client : Mistral | null = null ;
export function getMistralClient (Mistral {
if (!_client) {
const apiKey = process.env .MISTRAL_API_KEY ;
if (!apiKey) throw new Error ('MISTRAL_API_KEY not set' );
_client = new Mistral ({
apiKey,
timeoutMs : 30_000 ,
maxRetries : 3 ,
});
}
return _client;
}
export function resetClient (void {
_client = null ;
}
import os
from mistralai import Mistral
_client = None
def get_client () -> Mistral:
global _client
if _client is None :
api_key = os.environ.get("MISTRAL_API_KEY" )
if not api_key:
raise RuntimeError("MISTRAL_API_KEY not set" )
_client = Mistral(api_key=api_key, timeout_ms=30_000 , max_retries=3 )
return _client
Step 2: Structured Output with JSON Schema import { z } from 'zod' ;
const TicketSchema = z.object ({
category : z.enum (['bug' , 'feature' , 'question' ]),
severity : z.enum (['low' , 'medium' , 'high' , 'critical' ]),
summary : z.string (),
});
type Ticket = z.infer <typeof TicketSchema >;
async function classifyTicket (text : string Promise <Ticket > {
const client = getMistralClient ();
const response = await client.chat .complete ({
model : 'mistral-small-latest' ,
messages : [
{ role : 'system' , content : 'Classify the support ticket.' },
{ role : 'user' , content : text },
],
responseFormat : {
type : 'json_schema' ,
jsonSchema : {
name : 'ticket_classification' ,
schema : {
type : 'object' ,
properties : {
category : { type : 'string' , enum : ['bug' , 'feature' , 'question' ] },
severity : { type : 'string' , enum : ['low' , 'medium' , 'high' , 'critical' ] },
summary : { type : 'string' },
},
required : ['category' , 'severity' , 'summary' ],
},
},
},
});
const raw = JSON .parse (response.choices ?.[0 ]?.message ?.content ?? '{}' );
return TicketSchema .parse (raw);
}
Step 3: Streaming with Accumulated Result interface StreamResult {
content : string ;
finishReason : string ;
}
async function streamWithAccumulation (
messages : Array <{ role: string ; content: string }>,
onChunk : (text: string ) => void ,
): Promise <StreamResult > {
const client = getMistralClient ();
const stream = await client.chat .stream ({
model : 'mistral-small-latest' ,
messages,
});
let content = '' ;
let finishReason = '' ;
for await (const event of stream) {
const delta = event.data ?.choices ?.[0 ];
if (delta?.delta ?.content ) {
content += delta.delta .content ;
onChunk (delta.delta .content );
}
if (delta?.finishReason ) {
finishReason = delta.finishReason ;
}
}
return { content, finishReason };
}
Step 4: Python Async Pattern import asyncio
from mistralai import Mistral
async def process_batch (prompts: list [str ], model: str = "mistral-small-latest" ):
"""Process multiple prompts concurrently with semaphore for rate limiting."""
client = Mistral(api_key=os.environ["MISTRAL_API_KEY" ])
semaphore = asyncio.Semaphore(5 )
async def process_one (prompt: str ) -> str :
async with semaphore:
response = await client.chat.complete_async(
model=model,
messages=[{"role" : "user" , "content" : prompt}],
)
return response.choices[0 ].message.content
results = await asyncio.gather(*[process_one(p) for p in prompts])
return results
Step 5: Retry with Exponential Backoff async function withRetry<T>(
fn : () => Promise <T>,
maxRetries = 3 ,
): Promise <T> {
for (let attempt = 0 ; attempt <= maxRetries; attempt++) {
try {
return await fn ();
} catch (error : any ) {
const status = error.status ?? error.statusCode ;
const retryable = status === 429 || status >= 500 ;
if (!retryable || attempt === maxRetries) throw error;
const retryAfter = error.headers ?.get ?.('retry-after' );
const delay = retryAfter
? parseInt (retryAfter) * 1000
: Math .min (1000 * 2 ** attempt, 30_000 );
console .warn (`Attempt ${attempt + 1 } failed (${status} ), retrying in ${delay} ms` );
await new Promise (r =>setTimeout (r, delay));
}
}
throw new Error ('Unreachable' );
}
const response = await withRetry (() =>
client.chat .complete ({
model : 'mistral-large-latest' ,
messages : [{ role : 'user' , content : 'Hello' }],
})
);
Step 6: Token Usage Tracking interface UsageStats {
totalPromptTokens : number ;
totalCompletionTokens : number ;
totalRequests : number ;
costUsd : number ;
}
const PRICING : Record <string , { input : number ; output : number }> = {
'mistral-small-latest' : { input : 0.1 , output : 0.3 },
'mistral-large-latest' : { input : 0.5 , output : 1.5 },
'mistral-embed' : { input : 0.1 , output : 0 },
'codestral-latest' : { input : 0.3 , output : 0.9 },
};
class UsageTracker {
private stats : UsageStats = { totalPromptTokens : 0 , totalCompletionTokens : 0 , totalRequests : 0 , costUsd : 0 };
record (model : string , usage : { promptTokens ?: number ; completionTokens ?: number }): void {
const pt = usage.promptTokens ?? 0 ;
const ct = usage.completionTokens ?? 0 ;
this .stats .totalPromptTokens += pt;
this .stats .totalCompletionTokens += ct;
this .stats .totalRequests ++;
const p = PRICING [model] ?? PRICING ['mistral-small-latest' ];
this .stats .costUsd += (pt / 1e6 ) * p.input + (ct / 1e6 ) * p.output ;
}
report (): UsageStats { return { ...this .stats }; }
}
