Manage API keys

Get your LastMile API key

• Log in or sign up for free at https://lastmileai.dev
• Navigate to API Keys console
• Click + New Key

Export the API key you generated as an environment variable. Alternatively, you can also pass it directly into the Lastmile client.

bash

export LASTMILE_API_TOKEN="your_api_key"

python

from lastmile import Lastmile
from lastmile.lib.auto_eval import AutoEval

# Recommended: AutoEval client SDK (higher-level APIs)
client = AutoEval(api_token="api_token_if_LASTMILE_API_TOKEN_not_set")

# Lastmile client (REST API wrappers)
client = Lastmile(
  bearer_token="api_token_if_LASTMILE_API_TOKEN_not_set",
)

node.js

import { Lastmile } from 'lastmile';
import { AutoEval } from "lastmile/lib/auto_eval";

// Recommended: AutoEval client SDK (higher-level APIs)
const client = new AutoEval({
  apiKey: "api_token_if_LASTMILE_API_TOKEN_not_set" 
});

// Lastmile client (REST API wrappers)
const restClient = new Lastmile({
  bearerToken: "api_token_if_LASTMILE_API_TOKEN_not_set",
});

Configure Weights & Biases API token

AutoEval allows you to track detailed training runs in your own Weights & Biases account. To do so, navigate to the API Keys console, and save your W&B API key. Subsequent fine-tuning runs will be tracked in your account.
