Models

Choose the right model for your task.

Pass model to select a model:

Model	API String	Input (per 1M tokens)	Output (per 1M tokens)
Claude Sonnet 4.6	claude-sonnet-4.6	$3.60	$18.00
Claude Opus 4.6	claude-opus-4.6	$6.00	$30.00
GPT-5.4 mini	gpt-5.4-mini	$0.90	$5.40

We recommend Claude Sonnet 4.6 (claude-sonnet-4.6). It’s the model we optimize for the most right now.

Python

from browser_use_sdk.v3 import AsyncBrowserUse

client = AsyncBrowserUse()
result = await client.run(
    "List the top 20 posts on Hacker News today with their points",
    model="claude-sonnet-4.6",
)
print(result.output)

import { BrowserUse } from "browser-use-sdk/v3";

const client = new BrowserUse();
const result = await client.run(
  "List the top 20 posts on Hacker News today with their points",
  { model: "claude-sonnet-4.6" },
);
console.log(result.output);

curl -X POST https://api.browser-use.com/api/v3/sessions \
  -H "X-Browser-Use-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"task": "List the top 20 posts on Hacker News", "model": "claude-sonnet-4.6"}'

Bring your own key

Connect your own Anthropic, OpenAI, or Google API key. You pay your provider directly + a 0.2× orchestration fee on provider list token prices.

1. Add your provider key in the dashboard under Settings → API Keys → Bring Your Own Key.
2. Pass use_own_key=True on the session:

Python

result = await client.run(
    "List the top 20 posts on Hacker News today with their points",
    model="claude-sonnet-4.6",
    use_own_key=True,
)

const result = await client.run(
  "List the top 20 posts on Hacker News today with their points",
  { model: "claude-sonnet-4.6", useOwnKey: true },
);

curl -X POST https://api.browser-use.com/api/v3/sessions \
  -H "X-Browser-Use-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"task": "List the top 20 posts on Hacker News", "model": "claude-sonnet-4.6", "useOwnKey": true}'

To default every session on a client to BYOK, set it once on the constructor:

Python

client = AsyncBrowserUse(use_own_key=True)

const client = new BrowserUse({ useOwnKey: true });

The provider key on your project must match the model you pick — Claude models use your Anthropic key, GPT models use your OpenAI key, Gemini models use your Google key.
