Anthropic Drops Claude Opus 4.7 — Claims 92% Honesty Rate

Anthropic released Claude Opus 4.7 on Thursday, a hybrid reasoning model that the company says is significantly less likely to hallucinate or engage in sycophancy than any prior Claude model — or competing frontier models.

According to the system card, Opus 4.7 shows “large reductions in the rate of important omissions, and moderate improvements in factuality.” The 92% honesty benchmark is a notable jump, and Anthropic is clearly positioning safety and reliability as its competitive edge heading into the second half of 2026.

White House Races to Get Anthropic Mythos Access Amid Security Fears

The U.S. government is in active talks with Anthropic to deploy its frontier model, Claude Mythos Preview, across major federal agencies. According to Bloomberg and Reuters, the White House is pushing for access despite ongoing concerns that Mythos could uncover – and potentially create – cybersecurity vulnerabilities at unprecedented speed.

Anthropic CEO Dario Amodei met with White House Chief of Staff Susie Wiles last week to discuss the implications. The irony is hard to miss: the government wants the model precisely because it is powerful enough to be dangerous.

Google Teams Up with Marvell on Next-Gen AI Inference Chips

Alphabet’s Google is in talks with Marvell Technology to co-develop two new chips purpose-built for running AI models more efficiently. One is a memory processing unit designed to pair with Google’s TPUs, and the other is a new TPU built specifically for inference workloads.

Marvell shares jumped on the news Monday. The move signals Google is doubling down on custom silicon rather than relying solely on Nvidia – a trend that could reshape the AI chip landscape as inference costs become the next major battleground.

UK Launches £500M Sovereign AI Fund

The UK government officially launched its £500 million ($675M) Sovereign AI Fund last week, aimed at scaling homegrown AI startups across model development, agentic AI, and drug discovery. Tech Secretary Liz Kendall announced the fund at autonomous driving company Wayve’s offices.

UK AI startups raised £6 billion in venture capital last year, and have already pulled in more than half that figure in just the first three months of 2026. The fund will operate like a state-backed VC, making direct investments in British AI firms.
