Meta Rolls Out Muse Spark 1.3, Closing the AI Gap
Meta CEO Mark Zuckerberg announced the rollout of Muse Spark 1.3, the fourth release of the model family in five months. According to Artificial Analysis, the publicly available 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, placing Meta among the top three AI model providers behind only Anthropic. Gains come from agentic tasks and scientific reasoning. At $0.55 per task, no model with 59+ points is cheaper. Meta has committed to open-weighting Muse Spark 1.2, while the decision on 1.3 remains open. A 'Watermelon' flagship model is expected in autumn, reportedly matching GPT-5.5 on key benchmarks.
Meta's Muse Spark 1.3 release demonstrates rapid AI capability gains at industry-leading cost efficiency, strengthening the competitive AI infrastructure landscape that underpins AdTech/MarTech automation and agentic tools.

BBC Director-General Unveils Silicon Valley-Style Overhaul
BBC Director-General Matt Brittin, formerly of Google, has announced a major cultural and strategic overhaul of the British broadcaster.
