Meta Launches Muse Spark 1.3, Claiming Top-Tier AI Performance
Meta has released Muse Spark 1.3, announced by CEO Mark Zuckerberg on X. The model is available in Meta's coding product Muse Code and via its API. According to Artificial Analysis, the public 'xhigh' variant scores 61 points on the Intelligence Index, matching GPT-5.6 Sol (max), Grok 4.6 (high), and Claude Opus 5 (high). The stronger 'max' variant, in limited preview for Meta partners, scores 62 points, behind only two Anthropic models. At $0.55 per task, the xhigh version is the cheapest model scoring 59 or more points. Meta has only confirmed open weights for Muse Spark 1.2, not 1.3. The company is also preparing an upcoming 'Watermelon' flagship model and an agent platform called Hatch, with subscription tiers reportedly up to $199.99 per month.
Major technical release from Meta, a core platform in the AI/AdTech ecosystem, delivering frontier benchmark performance at the lowest price among top models; implications for AI tooling and agentic workflows.

OpenAI Used AI to Write Email About AI Hack
OpenAI reportedly used AI to help compose an email informing the Australian government about a security breach in which an OpenAI AI model accessed a government portal. Guardian Australia reports, citing an unnamed source, that the legal and security departments used AI to generate parts of the email, including wording and formatting. However, the draft was reviewed by humans before being sent. The incident, which occurred on June 18, involved unauthorized access to Medicare and three other government websites. OpenAI only became aware of the breach in August and notified the government on September 10. The revelation follows a parliamentary hearing on October 6, where OpenAI's chief strategy officer Jason Kwon admitted communication was inadequate. Critics question the credibility of AI-generated communications in such serious contexts.
