site:ai-sdk.dev @ai-sdk/openai v1.3.24 responses streamObject temperature
💡 Result:
In the Vercel AI SDK, including version 1.3.24 (and subsequent versions), the streamObject function supports the temperature parameter as a configuration option for the model [1][2][3]. When using @ai-sdk/openai, this parameter is passed through to the OpenAI provider [3]. The temperature value should be a number between 0 and 1, where higher values (e.g., 0.8) increase randomness and lower values (e.g., 0.2) make the output more deterministic [4]. You can define this within your streamObject call as follows: import { streamObject } from 'ai'; import { openai } from '@ai-sdk/openai'; import { z } from 'zod'; const { partialObjectStream } = streamObject({ model: openai('gpt-4o'), temperature: 0.7, // Set your desired temperature here schema: z.object({ // your schema definition }), prompt: 'Your prompt here', }); The temperature setting is part of the common model parameters exposed by the AI SDK's core functions [1][2][3]. Note that while streamObject is a dedicated function for structured data, the SDK also supports structured output via the output parameter in streamText in newer versions [5][6].

site:developers.openai.com/api/docs/guides/latest-model GPT-6 Astra temperature Responses API
💡 Result:
To use GPT-6 Astra, you must set the model parameter to gpt-6-astra within your Responses API request [1]. The Responses API is the designated interface for interacting with GPT-6 Astra [1]. While the provided documentation confirms the model supports existing API capabilities such as structured outputs, streaming, and tool calling, specific technical details regarding the temperature parameter for the Responses API are not explicitly detailed in the available summary [1]. In OpenAI's standard API architecture, the temperature parameter typically governs the randomness of the model's output, but you should verify its availability and range specifically within the Responses API implementation through your developer console or the official migration guides linked in your documentation [1]. GPT-6 Astra is capable of mid-turn steering, allowing you to send additional instructions or corrections while the model is actively processing [1]. Note that it does not support the none reasoning effort, and fast mode is unavailable when using EU data residency [1].

site:ai-sdk.dev/docs @ai-sdk/openai responses API streamObject temperature
💡 Result:
In the Vercel AI SDK, the streamObject function has been deprecated in favor of using streamText with the output property [1][2]. For both legacy streamObject and the current streamText function, the temperature parameter is supported as a standard request setting [3][4]. It is passed through to the model provider (such as OpenAI) to control the randomness of the output [4]. Key implementation details include: - Usage: You can include temperature as a top-level property in the configuration object passed to streamText [3][4]. - Recommendations: It is generally recommended to set temperature or topP, but not both [3][4]. For structured data generation (which replaces the deprecated streamObject workflow), a temperature of 0 is often recommended to ensure deterministic, consistent results that adhere to your specified schema [5]. - Migration: If you are currently using streamObject, you should migrate to streamText using output: Output.object({ schema: ... }) [6][2]. The temperature setting remains available in this new pattern [3][7].

@ai-sdk/openai 1.3.24 createOpenAI responses API model factory
💡 Result:
In the @ai-sdk/openai package (including version 1.3.24), createOpenAI is used to instantiate a customized OpenAI provider [1][2]. The returned provider instance acts as a model factory, allowing you to create language models by invoking the provider function or using specific factory methods [1][3]. Key details regarding the Responses API and model factory usage include: Default API Selection: When you invoke the provider instance directly (e.g., openai('model-id')), it automatically selects the appropriate API based on the model ID [1][4]. As of AI SDK 5, the OpenAI Responses API is the default API used by the provider [1][5]. Model Factory Methods: You can explicitly choose the desired API by using the following factory methods on the provider instance [1][4]:.responses(modelId): Explicitly uses the OpenAI Responses API [1][3]..chat(modelId): Uses the OpenAI Chat Completions API [1][3]. This is recommended if your base URL or proxy environment only supports Chat Completions rather than the Responses API [1][6]..completion(modelId): Uses the OpenAI Completions API [7][3]. Customization: If your infrastructure requires a custom base URL that does not support the Responses API, you should use the.chat method or the dedicated OpenAI-compatible provider [1][6][4]. The createOpenAI factory accepts an optional configuration object to set headers, custom base URLs, and other provider-wide settings [1][3][8].

site:github.com/vercel/ai "@ai-sdk/openai@1.3.24" "responses(modelId)" "chat(modelId)"
💡 Result:
In the @ai-sdk/openai package (v1.3.24), the OpenAI provider instance (exported as openai) allows you to create specific language model instances using factory methods [1][2][3]. The chat and responses methods are used as follows: openai.chat(modelId) This method creates an OpenAI model configured for the Chat Completions API [2][4][3]. It is the recommended approach if your use case requires standard chat functionality or if you are using a custom base URL that specifically supports the Chat Completions API [1][2]. openai.responses(modelId) This method creates an OpenAI model configured for the OpenAI Responses API [2][4][3]. Note on Defaults: Since AI SDK 5, the OpenAI provider defaults to the Responses API when using the primary factory method (e.g., openai('gpt-4o')) [1][5]. If you need to explicitly select the Chat Completions API, you must use openai.chat('modelId') [1][5]. Example usage: import { openai } from '@ai-sdk/openai'; // Uses the default (Responses API as of AI SDK 5) const modelDefault = openai('gpt-4o'); // Explicitly uses the Chat Completions API const modelChat = openai.chat('gpt-4o'); // Explicitly uses the Responses API const modelResponses = openai.responses('gpt-4o');

Use the Responses model for GPT-6 Astra.
getModel() returns openai('gpt-6-astra') from both default branches. The pinned AI SDK uses openai.responses(modelId) for the Responses API. Return openai.responses('gpt-6-astra') from both branches because GPT-6 Astra requires the Responses API.
