Muse Spark 1.2

by Meta

Released 607 days after Llama 3.3 70B · All Meta releases

Muse Spark 1.2 arrived on August 5, 2026 as the coding-focused flagship of Meta Superintelligence Labs' Muse family, following the original Spark in April and the 1.1 refresh in July. The model keeps the line's million-token context window and multimodal input across text, images, audio, and video, while sharpening first-attempt coding accuracy and long multi-step reasoning. Debugging sprawling codebases, validating changes that touch thousands of files, and orchestrating parallel subagents are the workloads it was built for, and it also powers Muse Code, Meta's terminal coding agent. Tool use, MCP integrations, and persistent background agents make it a strong pick for deep agentic software engineering pipelines.

Get started

Call Muse Spark 1.2 through the qynio gateway with one API key. Let your coding agent set it up, or call it directly — qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.QYN_API_KEY,
baseURL: "https://api.qyn.io/v3/compat",
});
const completion = await client.chat.completions.create({
model: "meta/muse-spark-1.2",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
