Overview & Architecture

GPT-5.6 Sol is OpenAI's flagship deliberative reasoning engine optimized for rapid execution loops. Built with solar-tier sparse attention and active reasoning traces, Sol solves complex multi-step problems in a fraction of traditional deliberative latency. It is particularly adept at iterative tool use, mathematical analysis, and autonomous agent coordination.

Execute via Gruvo

Unified Endpoint

Connect through Gruvo with OpenAI-compatible client libraries. Gruvo translates requests, manages provider streaming, and applies caching automatically.

import OpenAI from "openai";

// Configure client with Gruvo's unified AI gateway
const gruvo = new OpenAI({
  baseURL: "https://api.gruvo.ai/v1",
  apiKey: process.env.GRUVO_API_KEY,
  defaultHeaders: {
    "X-Gruvo-Provider": "openai",
  },
});

const completion = await gruvo.chat.completions.create({
  model: "gpt-5.6-sol",
  messages: [
    { role: "system", content: "You are a production reasoning assistant." },
    { role: "user", content: "Analyze the architecture of our service." },
  ],
  temperature: 0.2,
});

console.log(completion.choices[0].message.content);
