Meta Releases Muse Spark 1.3 With Top-Tier AI Benchmarks
Meta has launched Muse Spark 1.3, announced by Mark Zuckerberg on X. The public xhigh variant scores 61 points on the Artificial Analysis Intelligence Index, matching GPT-5.6 Sol (max), Grok 4.6 (high), and Claude Opus 5 (high), while the limited max preview reaches 62 points. Only Anthropic's Claude Fable 5.1 and Claude Opus 5 rank higher. Gains are driven by agentic benchmarks and scientific reasoning, though some scores declined. Pricing remains unchanged, and Muse Spark 1.3 is cheaper than comparable peer models. Meta has committed to open-weight release for Muse Spark 1.2, but not yet for 1.3. A flagship model codenamed Watermelon is expected in autumn, reportedly matching GPT-5.5. Meta is also preparing Hatch, its first paid AI agent platform.
Meta's new flagship AI model Muse Spark 1.3 significantly advances agentic and reasoning capabilities at a lower price point, strengthening competition in AI infrastructure and open-weight models, which are increasingly relevant for advertising automation and AI-driven marketing technology.

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.
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.
Ethereum Researcher Warns AI Could Break Blockchain Encryption
Justin Drake, a researcher at the Ethereum Foundation, has cautioned that artificial intelligence, not just quantum computers, could break the ECDSA signature scheme used by Bitcoin and Ethereum within months. He urges the industry to adopt a 'bunker mode' migration of funds to addresses that have never signed a transaction, as their public keys remain hidden, and calls on major custodians like Binance and Tether to harden their cold storage. While Ethereum co-founder Vitalik Buterin supports long-term hash-based cryptography, he advises against panic. Critics, including Coinbase's Yehuda Lindell and Jan3's Samson Mow, label the warning overblown. Proposals like BIP-360 and BIP-361 aim to phase out vulnerable addresses but face community opposition. Both Drake and others note the traditional quantum threat (Q-Day) is decades away, but AI could accelerate the timeline.
