Models

Choose a V4 model and understand its token pricing.

Pass one of these API strings as model when creating a run:

Model	API string	Input	Cache read	Output	BYOK
Claude Opus 5	claude-opus-5	$6.00	$0.60	$30.00	Anthropic
Grok 4.5	grok-4.5	$2.40	$0.36	$7.20	—
GPT-5.6	gpt-5.6	$6.00	$0.60	$36.00	OpenAI
Gemini 3.5 Flash	gemini-3.5-flash	$1.80	$0.18	$10.80	Google
MiniMax M3	minimax-m3	$0.36	$0.072	$1.44	—

Token prices are USD per 1 million tokens. Browser sessions ($0.02/hour) and network traffic ($5/GB managed proxy or $0.20/GB proxyless/BYOP) are charged separately. See full pricing.

Grok 4.5 gives the best balance of price and accuracy. MiniMax M3 is the default and cheapest option; use Claude Opus 5 when accuracy matters most.

New model strings can reach the API before the TypeScript SDK’s generated union. If TypeScript rejects a model listed above, call POST /api/v4/runs directly for that model.

Python

from browser_use_sdk.v4 import BrowserUse

client = BrowserUse()
run = client.runs.create(
    "Compare three project-management tools",
    model="grok-4.5",
)

import { BrowserUse } from "browser-use-sdk/v4";

const client = new BrowserUse();
const run = await client.runs.create({
  task: "Compare three project-management tools",
  model: "grok-4.5",
});

curl https://api.browser-use.com/api/v4/runs \
  -H "X-Browser-Use-API-Key: $BROWSER_USE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"task":"Compare three PM tools","model":"grok-4.5"}'

Bring your own key

Add an Anthropic, OpenAI, or Google key under Settings → API Keys → Bring Your Own Key. V4 uses it automatically for matching models; no request flag is needed. You pay the provider directly, plus a 0.2× Browser Use orchestration fee. Grok and MiniMax currently use Browser Use-managed keys.
