Meta Launches Muse Spark 1.3, Closing AI Gap with Anthropic
Meta CEO Mark Zuckerberg announced the rollout of Muse Spark 1.3 on X. The model is available via Muse Code, Meta's answer to Claude Code and OpenAI Codex, as well as through Meta's API. According to Artificial Analysis, the public xhigh variant scores 61 points in the Intelligence Index, tying it with GPT-5.6 Sol (max), Grok 4.6 (high), and Claude Opus 5 (high). The stronger max variant, available in a limited partner preview, scores 62, behind only Claude Fable 5.1 (max) and Claude Opus 5 (max). Gains come mainly from agentic tasks and scientific reasoning. Token pricing remains unchanged at $1.25 per million input tokens and $4.25 per million output tokens. Meta confirmed open-weights release for Muse Spark 1.2, while a decision on open-weights for 1.3 is pending. A flagship model codenamed Watermelon is expected in fall, and the agent platform Hatch may launch with subscriptions up to $199.99 per month.
Meta's AI model release is a major technical event from a dominant platform, with significant implications for AI cost/performance and its use in marketing technology and AI-powered advertising tools.

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.
AI-Native CFO Tools Transform Finance Role
This article by a16z discusses how AI is transforming the role of the CFO and the finance function. It argues that AI removes data bottlenecks, making finance software more autonomous. This leads to smaller, higher-leverage finance teams, the emergence of 'finance engineers' who build custom tools, and a shift toward continuous planning and controls. The article highlights portfolio companies like Rillet, Concourse, and Lio, and notes that Anthropic's finance team has built 70+ AI skills, while OpenAI's finance team uses custom GPTs. The CFO is becoming a builder and architect of the company's operating system, with a growing mandate in strategic decisions.
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.
