Meta's Muse Spark 1.3 Catches Up With Top AI Rivals
Meta has released Muse Spark 1.3, announced by CEO Mark Zuckerberg, with the xhigh variant scoring 61 points on Artificial Analysis' Intelligence Index, matching GPT-5.6 Sol (max), Grok 4.6 (high) and Claude Opus 5 (high). The stronger max version, in limited preview for Meta partners, scores 62 points and is surpassed only by two Anthropic models. Meta's gains come particularly from agentic tasks and scientific reasoning. The model is priced at $0.55 per task, cheaper than comparable frontier models, with unchanged token pricing. Zuckerberg also promised open-weights versions, starting with Muse Spark 1.2, while a decision on 1.3 remains open. Meta's upcoming flagship, codenamed Watermelon, is expected in autumn and reportedly matches GPT-5.5 internally. The release marks Meta's return to the top tier of AI model providers.
Meta, a major platform, released a frontier AI model with top-tier benchmark performance and significant open-weight implications, directly affecting AI infrastructure and agentic automation used across AdTech and MarTech.

AI Price War: OpenAI Gains Ground on Anthropic
The AI price war is intensifying, with OpenAI gaining significant ground on Anthropic among business customers. According to a Wall Street Journal report, spending on OpenAI and Anthropic models via the OpenRouter platform was nearly evenly split in September among roughly 120,000 companies using both, a shift from January when Anthropic held about 75% of that spending. OpenAI's aggressive price cuts on its GPT-5.6 lineup, including an 80% reduction on its smallest model Luna and 20% on Terra, are driving this change. Companies are increasingly prioritizing cost, combining multiple providers and using cheaper models for simpler tasks. Anthropic faces its own challenges, including capacity issues with Claude Code and data retention criticism. Both companies are preparing for IPOs, needing to demonstrate sustainable revenue to justify valuations exceeding $1 trillion.
AWNY, Jupiter Fest Spotlight Agentic Ads and Open Web
Advertising Week New York and the inaugural Jupiter Festival Miami highlighted the industry's shift toward agentic advertising and anxieties about the open web's future. Major announcements included TikTok's off-platform ad expansion and a new AI shopping agent, Meta's AI campaign assistant testing, and OpenAI's visual ads introduction. Paramount's $110 billion acquisition of Warner Bros. Discovery closed, forming Skydance. Key themes were the threat of AI to publisher traffic, the rise of AI visibility tools, the early stage of agentic media buying, unsolved cross-platform measurement, and the booming sports and retail media sectors. Deals included PubX's acquisition of Compliant and a $5 million Series A, and OpenAI's reported $30 billion round talks with BlackRock and UAE investors.
Musk's Grok Bot to Use Rival AI Models Like Claude
Elon Musk announced that Grok Bot, an agent app from his AI unit (formerly xAI, now part of SpaceX and recently renamed SpaceXAI/SpaceXSI), will no longer rely solely on its own Grok models. Instead, it will pick 'the best back-end model for the respective task,' citing examples such as Anthropic's Claude Opus 5.5, Midjourney, and Suno. The announcement, first reported by The Information, follows user complaints about access issues. This strategic shift acknowledges that xAI's models don't lead in all areas—for instance, Claude Opus 5.5 outperforms competitors on the Artificial Analysis ranking. The move mirrors a broader industry trend of multi-model routing, as seen with Microsoft's Copilot and Perplexity, and comes despite reports of SpaceX planning $40 billion in debt for Nvidia chips.
