Meta Releases Muse Spark 1.3, Claims Biggest Coding Leap
Meta CEO Mark Zuckerberg announced the rollout of Muse Spark 1.3 on X, calling it the company's biggest jump in coding and agent-based work. The model is available through Muse Code and Meta's API. According to Artificial Analysis, the public xhigh variant scores 61 points on its Intelligence Index, tying GPT-5.6 Sol (max), Grok 4.6 (high), and Claude Opus 5 (high); the limited max variant scores 62, trailing only Anthropic's Claude Fable 5.1 (max) and Claude Opus 5 (max). The xhigh version costs $0.55 per task, undercutting rivals with similar scores. Gains come mainly from agentic benchmarks, while two benchmarks showed slight declines. Meta plans to release open weights for Muse Spark 1.2, with 1.3 still undecided, and is developing a flagship model codenamed Watermelon plus a paid AI agent platform, Hatch.
Meta's next-generation AI model release significantly shifts the competitive benchmark landscape, providing cheaper, stronger AI capabilities that can power AI-driven advertising, creative, and agentic tools.

Grok Bot Searches X, Integrates Rival AI Models
SpaceXAI has enhanced its AI agent Grok Bot with the ability to continuously search and analyze the entire X platform. Users can now deploy the agent for 24/7 social listening, brand monitoring, and trend analysis, similar to Google's Information Agents. Grok Bot will also integrate other AI models from competitors, such as Claude Opus 5.5, Midjourney, and Suno, depending on the task. This move signals a shift towards multi-model AI agents and expands the capabilities of AI-driven social media analytics.
OpenAI Expert: Optimize Token Efficiency for AI Agents
In an interview with t3n, Maximilian Hudlberger, Applied AI Engineer at OpenAI, explains that despite decreasing token prices, companies' AI costs can rise significantly, especially with the increasing use of AI agents. He argues that the true measure of cost-effectiveness is not the price per token, but rather the number of tasks completed with a given budget. Unnecessary costs often arise from using the most powerful model for every task, when simpler models would suffice. Businesses should therefore think in terms of completed tasks and optimize their model selection for economic efficiency. The article highlights that the growing deployment of AI agents in enterprise workflows is driving up token consumption, making cost management a critical business factor.
