Claude Sonnet 5 lands as the most capable model you can actually deploy at scale today, pitched as Opus-class autonomy at a Sonnet price. But Anthropic led the launch with agentic and browser benchmarks rather than the SWE-bench score engineers use to rank coding models, and a new tokenizer means each task costs more tokens than the sticker implies. A review of what is new, what it costs, and whether you still need Opus.

With the unveiling of Jalapeño, its first custom AI accelerator, OpenAI has completed a transformation few predicted when it launched ChatGPT three years ago. The company now designs its own chips, builds its own data centers, and is developing its own consumer hardware. The question is what happens to everyone who supplied those things before.

SpaceX's IPO registration statement describes a plan to deploy orbital AI compute satellites as early as 2028, betting that space solves the power and cooling constraints strangling terrestrial AI infrastructure. The financials tell a more grounded story: the only profitable segment is Starlink broadband, which funds everything else.

OpenAI shipped GPT-5.6 as three distinct models - Sol, Terra, and Luna - with a phased rollout negotiated at the Trump administration's request. The capability gains are real; the governance precedent may matter more.

Ten days after the US Commerce Department used a private export-control letter to pull Anthropic's Fable 5 and Mythos 5 offline worldwide, neither model is back. What began as a jailbreak dispute has become a structural standoff - and the rough outline of an ad hoc licensing regime for frontier AI.

Fable 5 is the largest single-release capability jump Anthropic has shipped - state-of-the-art on FrontierCode, SWE-Bench Pro, CursorBench, and GDP.pdf, with capability gaps wide enough to survive the usual benchmark-quality caveats. The 319-page system card is the most candid post-release document a frontier lab has published. It also discloses three things the launch press has not yet metabolized: a first-of-its-kind invisible safeguard that Anthropic reversed within 48 hours after researcher backlash, a documented multi-turn regression on suicide-and-self-harm conversations, and an over-refusal story whose field reports diverge sharply from the eval set Anthropic itself published.
