# Cohere

> Connect your Cohere-powered application to Latitude for observability.

## Overview

This guide shows you how to integrate **Latitude Telemetry** into an application that uses the **Cohere** SDK.

<Check>
  You'll keep calling Cohere exactly as you do today. Telemetry simply
  observes and enriches those calls.
</Check>

***

## Requirements

* A **Latitude account** and **API key**
* A **Latitude project slug**
* A project that uses the **Cohere SDK**

        import { CohereClient } from "cohere-ai"

## Streaming

When streaming, consume the stream inside `capture()` so the span covers the full operation:

  <Tab title="TypeScript">
    ```ts theme={"theme":{"light":"github-light","dark":"github-dark"}}
    await capture("stream-reply", async () => {
      const stream = await client.chatStream({
        model: "command-a-03-2025",
        message: input,
      })

      for await (const event of stream) {
        if (event.eventType === "text-generation") {
          res.write(event.text)
        }
      }
      res.end()
    })
    ```
  </Tab>

  <Tab title="Python">
    ```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
    def stream_reply():
        for event in client.chat_stream(
            model="command-a-03-2025",
            message=input,
        ):
            if event.event_type == "text-generation":
                yield event.text

    capture("stream-reply", stream_reply)
    ```
  </Tab>
</Tabs>

## Seeing Your Traces

Once connected, traces appear automatically in Latitude:

1. Open your **project** in the Latitude dashboard
2. Each execution shows input/output messages, model, token usage, latency, and errors
