About OpenAI: GPT-5 (batch)
GPT-5 (batch) is a text model from OpenAI, listed on api14 under the model id openai/gpt-5:batch. It belongs to the GPT-5 family, which OpenAI describes as its most advanced model, with improvements in reasoning, code quality and user experience, and it is optimized for complex tasks that require step-by-step reasoning, instruction following and accuracy. The batch variant is the version you call through this endpoint.
The model accepts text, images and files as input and returns text. It has a context window of 400,000 tokens and can produce up to 128,000 output tokens, with a knowledge cutoff of 30 September 2024. Reasoning behaviour is exposed through parameters, so you can control how much internal reasoning the model performs and whether reasoning content is included in the response. Output can be constrained with structured outputs and response formats, and the model can call tools.
These capabilities point to workloads where the model has to read a lot of material and reason over it before answering. Long documents, mixed text and image inputs, and file attachments fit the input modalities and the large context window. Code review, multi-step analysis, extraction into a fixed schema and agent-style tool calling are natural fits given the reasoning controls, structured outputs and tool support. The 128,000 token output ceiling also suits tasks that produce long generated text rather than short replies.
You call the model through api14's OpenAI-compatible API using the model id openai/gpt-5:batch. The supported request parameters are include_reasoning, max_tokens, reasoning, reasoning_effort, response_format, seed, structured_outputs, tool_choice, tools and verbosity. Because the interface is OpenAI-compatible, existing OpenAI SDK clients and request shapes generally carry over with the model id swapped.
Keep the knowledge cutoff in mind: the model's built-in knowledge ends on 30 September 2024, so anything more recent needs to come from your prompt, attached files or tools. The batch variant is a text-output model, so tasks that require image or audio generation fall outside it. For straightforward, high-volume text work where reasoning depth is not the constraint, a lighter model may be a better fit.
How to call the OpenAI: GPT-5 (batch) API
- Create an API key in your dashboard.
- Install the official openai SDK for your language.
- Set baseURL to https://api14.com/api/v1 and model to "openai/gpt-5:batch".
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://api14.com/api/v1",
apiKey: process.env.API14_API_KEY,
});
const result = await client.chat.completions.create({
"model": "openai/gpt-5:batch",
"messages": [
{
"role": "user",
"content": "Explain vector databases in two sentences."
}
]
});
console.log(result.choices[0].message.content);
