Minor Changes

• #588 ba9efc5 Thanks @sameelarif! - Added support for offloading agent tasks to the API.

• #600 11e015d Thanks @sameelarif! - Added a stagehand.history array which stores an array of act, extract, observe, and goto calls made. Since this history array is stored on the StagehandPage level, it will capture methods even if indirectly called by an agent.

• #601 1d22604 Thanks @seanmcguire12! - add custom error classes

• #599 75d8fb3 Thanks @miguelg719! - cleaner logging with pino

• #620 566e587 Thanks @kamath! - You can now pass in an OpenAI instance as an llmClient to the Stagehand constructor! This allows you to use Stagehand with any OpenAI-compatible model, like Ollama, Gemini, etc., as well as OpenAI wrappers like Braintrust.

• #586 c57dc19 Thanks @sameelarif! - Added native Stagehand agentic loop functionality. This allows you to build agentic workflows with a single prompt without using a computer-use model. To try it out, create a stagehand.agent without passing in a provider.

v1.14.0

Minor Changes

• #518 516725f Thanks @sameelarif! - act() can now use observe() under the hood, resulting in significant performance improvements. To opt-in to this change, set slowDomBasedAct: false in ActOptions.

• #483 8c9445f Thanks @seanmcguire12! - When using textExtract, you can now do targetted extraction by passing an xpath string into extract via the selector parameter. This limits the dom processing step to a target element, reducing tokens and increasing speed. For example:

  const weatherData = await stagehand.page.extract({
    instruction: "extract the weather data for Sun, Feb 23 at 11PM",
    schema: z.object({
      temperature: z.string(),
      weather_description: z.string(),
      wind: z.string(),
      humidity: z.string(),
      barometer: z.string(),
      visibility: z.string(),
    }),
    modelName,
    useTextExtract,
    selector: xpath, // xpath of the element to extract from
  });

• #556 499a72d Thanks @kamath! - You can now set a timeout for dom-based stagehand act! Do this in act with timeoutMs as a parameter, or set a global param to actTimeoutMs in Stagehand config.

• #538 d898d5b Thanks @sameelarif! - Added gpt-4.5-preview and claude-3-7-sonnet-latest as supported models.

• #523 44cf7cc Thanks @kwt00! You can now natively run Cerebras LLMs! cerebras-llama-3.3-70b and cerebras-llama-3.1-8b are now supported models as long as CEREBRAS_API_KEY is set in your environment.

• #542 cf7fe66 Thanks @sankalpgunturi! You can now natively run Groq LLMs! groq-llama-3.3-70b-versatile and groq-llama-3.3-70b-specdec are now supported models as long as GROQ_API_KEY is set in your environment.
