Meta CEO Mark Zuckerberg has made a high-profile return to social media platform X after more than three years, using the occasion to unveil Muse Spark 1.1, the company's latest and most advanced artificial intelligence model. The launch marks Meta's latest push to strengthen its position in the global AI race against industry leaders OpenAI and Anthropic.
The new AI model is designed to deliver powerful coding capabilities, advanced reasoning, and autonomous task execution while remaining cost-effective for developers and enterprises.
Muse Spark 1.1 Brings Advanced Coding and Agentic AI Capabilities
Announcing the launch on X, Zuckerberg described Muse Spark 1.1 as a powerful AI model built for coding, software automation, and agentic workflows.
According to Meta, the model can:
Generate and debug code
Use software tools independently
Navigate desktop, mobile, and browser interfaces
Complete multi-step workflows with minimal human intervention
Handle complex reasoning tasks
One of the biggest highlights is its 1-million-token context window, enabling the model to process and remember extremely large documents, lengthy codebases, and complex projects in a single session.
Meta Model API Opens New Opportunities for Developers
Meta has introduced Muse Spark 1.1 through its newly launched Meta Model API, allowing developers to build AI-powered applications using the company's latest technology.
To encourage adoption, Meta is offering:
$20 free API credits for new developers
Pay-as-you-go pricing after free credits expire
Easy integration into AI applications and enterprise workflows
The company aims to make advanced AI development more affordable while expanding its ecosystem.
Pricing Designed to Compete in the AI Market
Meta has priced Muse Spark 1.1 at:
$1.25 per million input tokens
$4.25 per million output tokens
The pricing sits above OpenAI's GPT-5 Mini but remains below Anthropic's premium Claude Sonnet offering, positioning Muse Spark as a competitive option for businesses seeking powerful AI capabilities at lower costs.
Developed by Meta Superintelligence Labs
Muse Spark 1.1 has been developed by Meta Superintelligence Labs, the company's newly established AI research division.
The launch follows the recent introduction of Muse Image, Meta's AI-powered image generation model, highlighting the company's aggressive expansion across text, coding, image generation, and multimodal AI technologies.
Coming Soon to WhatsApp, Instagram and Facebook
Meta has confirmed that Muse Spark 1.1 will gradually replace existing Llama-based AI systems across its platforms, including:
Meta AI App
Meta AI Website
Meta Smart Glasses
Initially, the model is rolling out in the Thinking Mode of Meta AI before expanding to other services.
What is an Agentic AI Model?
Unlike traditional AI chatbots that simply answer questions, agentic AI models can independently plan tasks, interact with software tools, execute workflows, and make decisions with minimal human supervision.
Combined with its massive 1-million-token context window, Muse Spark 1.1 is designed to perform long-running, complex tasks that previously required multiple AI interactions.
Meta Intensifies AI Battle
With the launch of Muse Spark 1.1, Meta is significantly strengthening its AI portfolio as competition intensifies with OpenAI, Anthropic, Google, and other AI leaders. Zuckerberg's return to X alongside the announcement signals Meta's growing ambition to become one of the world's leading AI platforms by combining powerful multimodal models with competitive pricing and broader developer access.
