Meta's Muse Spark 1.3 Tops AI Rankings Behind Anthropic

Executive Signal Summary

Mark Zuckerberg announced the rollout of Meta's Muse Spark 1.3 AI model on X, claiming top-tier performance at a near-unbeatable price. The model, available through Muse Code and Meta's API, scores 61 points in Artificial Analysis' Intelligence Index for the public xhigh variant and 62 for the limited-preview max version. This places Meta among the top three model providers, behind only two Anthropic models (Claude Fable 5.1 and Claude Opus 5 max), and ahead of Google, OpenAI, and xAI. The gains come primarily from agentic tasks and scientific reasoning, with Tau3-Bench Banking improving from 35% to 47%. At $0.55 per task, it is the cheapest model scoring 59 or higher. Zuckerberg also teased an upcoming 'Watermelon' flagship model and open-weights releases, though only Muse Spark 1.2 weights are confirmed for release so far.

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.
