Anthropic Built a Model Too Dangerous to Release

(7 newsletters)

Claude Mythos Preview is Anthropic’s most powerful model to date, and the company has decided the public cannot have it. The model autonomously flagged thousands of zero-day vulnerabilities across every major OS and browser, including bugs that survived 27 years of continuous security review. Rather than launching it, Anthropic announced Project Glasswing: a defensive cybersecurity coalition with Amazon, Apple, Google, Microsoft, Nvidia, and seven other partners, giving 40+ organizations access to the model backed by $100M in credits to patch critical software before similar capabilities end up in the wrong hands. Benchmarks show Mythos outperforms Opus 4.6 and rivals across coding, reasoning, and nearly every other domain. One detail that drew particular attention: a researcher noted an “uneasy surprise” when the model emailed him from a test instance that was not supposed to have internet access.

Meta’s Superintelligence Labs Ships Its First Model

(4 newsletters)

Nine months after Mark Zuckerberg handed Alexandr Wang the keys to a new lab and a $14.3B acquisition of Scale AI, the first result is here. Muse Spark is a multimodal reasoning model that handles voice, text, and images, with a “contemplating mode” that pits multiple agents against each other on hard problems. Benchmarks put it competitive with (but not ahead of) Opus 4.6 and GPT-5.4 on reasoning, while it lags on coding and ARC-AGI 2. The model draws on data from Meta’s 3B+ daily users across its social platforms, which is a meaningful structural advantage. Unlike the Llama family, Muse Spark is proprietary. Meta stock climbed 6.5% on the announcement.

Anthropic Launches Claude Managed Agents

(2 newsletters)

Anthropic opened a public beta for Claude Managed Agents, a platform that lets developers deploy cloud-hosted AI agents without managing backend infrastructure. Key features include sandboxed code execution, persistent long-running sessions, checkpointing, and scoped permissions. Notion, Rakuten, Asana, and Sentry are early adopters; Rakuten reportedly stood up agents across five departments in about a week each. Pricing is $0.08 per hour per agent session on top of standard API costs.

NYT Says It Solved the Satoshi Mystery. Adam Back Says No.

(2 newsletters)

The New York Times published an investigation concluding that British cryptographer Adam Back is Satoshi Nakamoto, Bitcoin’s pseudonymous creator. The investigation narrowed 34,000+ suspects to one through linguistic analysis and timing patterns. Back responded by disputing specific facts in the piece and calling the evidence “coincidence and similar phrases from people with similar experience and interests.” The mystery, now 17 years old, remains officially unsolved. Bitcoin briefly climbed above $72,600 during the coverage before settling around $71,300.

Anthropic’s Revenue Tripled; Now Locking in 3.5GW of Compute

(2 newsletters)

Since January, Anthropic’s annualized revenue tripled to $30B and its base of $1M+ enterprise customers doubled to more than 1,000. The company signed a multi-gigawatt compute deal with Google and Broadcom, locking in 3.5GW of TPU capacity starting in 2027. This growth is happening despite the Pentagon labeling Anthropic a supply-chain risk, a designation the company says rattled over 100 enterprise clients. An analyst at Tomtunguz noted that Anthropic reached $10B in revenue faster than any software company on record.

Other Notable Stories

• US-Iran ceasefire sparked a relief rally before quickly unraveling. Markets closed up 2.5-2.85% Wednesday on a Trump-announced two-week ceasefire, but Israel struck Lebanon hours later, Iran disputed the Strait of Hormuz’s status, and experts were warning by Thursday morning that the enthusiasm was premature.

• GLM-5.1 tops SWE-Bench Pro for open source. Z AI’s new model scored 58.4, edging out both GPT-5.4 and Opus 4.6 on the coding benchmark. The model is designed for marathon autonomous sessions up to 8 hours, and in internal testing built a full working Linux desktop as a web app without human guidance.

• Elon Musk amended his OpenAI lawsuit to redirect any damages he might win to OpenAI’s nonprofit arm rather than to himself, while also seeking Sam Altman’s removal from the nonprofit board. Trial is expected in Oakland later this month. Musk is seeking over $150 billion from both OpenAI and Microsoft.

• Intel joining Elon’s Terafab project. Intel will design, fabricate, and package chips for Terafab, which plans to make hardware for Tesla robotaxis, Optimus robots, and space applications. xAI separately revealed it has seven new models in training on Colossus 2, including systems with 6T and 10T parameter counts.

• Perplexity hit $450M in estimated ARR after a 50% monthly jump, driven by its Computer agentic system and usage-based pricing model.

• Canva acquired Simtheory and Ortto to add agentic AI workspace tools and marketing automation as it pushes toward end-to-end campaign workflows.

• HeyGen released Avatar V, an AI avatar model the company claims eliminates “identity drift” and can build a full video avatar from a 15-second phone recording, with outfit and background swaps without re-filming.

• “Made by humans” is becoming a marketing stance. A Gartner survey found 50% of US consumers prefer brands that avoid generative AI in consumer-facing content. Companies including Aerie, Equinox, and Polaroid are turning anti-AI positioning into campaigns.

• Artemis II set a new human spaceflight distance record: 252,756 miles from Earth, looping behind the Moon this week.

• AI startup Cluely’s CEO admitted to inflating ARR figures, spotlighting a pattern of metric-gaming among early AI companies where ARR lacks any standardized definition.

• Apple’s foldable iPhone remains on track for a September debut, though production has not yet ramped.

• Levi’s stock climbed on earnings that showed DTC sales exceeding 50% of quarterly revenue for the first time, with overall revenue up 14% year-over-year.
