GPT-4
VerifiedAdvanced LLM excelling at complex reasoning and text generation.
About GPT-4
GPT-4 employs a transformer-based architecture optimized for sequential text prediction. Training draws from extensive public and licensed data sources to build broad knowledge coverage. Exact parameter counts and training details remain proprietary.
Its primary strengths lie in following detailed instructions and sustaining logical consistency across extended exchanges. The closed model receives regular refinements through OpenAI's managed updates.
Developers integrate GPT-4 through official APIs for chat interfaces, document summarization, and code assistance tools. Typical deployments appear in customer support systems, writing aids, and research assistants.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "openai/gpt-4",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: openai/gpt-4
Editor's verdict
GPT-4 is OpenAI's proprietary language models with a 8K-token context window.
At $60.00 per 1M output tokens, it is premium-priced for its class.
It is available through OpenAI's API and aggregators like OpenRouter.
Best suited to strong generalist performance across domains and coherent long-form text generation.
