See current pricing for model, browser, and network rates. See Thinking levels for V4 modelParams and the normalized thinkingLevel values available in V2 and V3.

V4 model IDs in the API schema

The V4 request schema accepts the following model IDs. The Cloud dashboard may show a smaller curated set; availability can also depend on your account’s rollout and configured provider key.

Provider	Model IDs	BYOK provider
Anthropic	`claude-opus-4.7`, `claude-opus-4.8`, `claude-opus-5`, `claude-fable-5`, `claude-sonnet-5`	Anthropic
OpenAI	`gpt-5.5`, `gpt-5.6`, `gpt-5.6-sol`, `gpt-5.6-terra`, `gpt-5.6-luna`	OpenAI
Google	`gemini-3-flash`, `gemini-3.1-pro`, `gemini-3.5-flash`, `gemini-3.6-flash`	Google
xAI	`grok-4.5`	—
Z.ai	`glm-5.2`	—
Moonshot AI	`kimi-k3`	—
MiniMax	`minimax-m3`	—

See Thinking levels for the reasoning controls accepted by each model. Not every model accepts modelParams.

Bring your own key

If BYOK is enabled for your project, 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. Models from other providers use Browser Use-managed keys. See pricing for current BYOK billing.
