GPT-5.6 Luna drops to $0.20 / $1.20 per million tokens from $1 / $6, and Terra to $2 / $12 from $2.50 / $15. Sol is unchanged, and its new Fast option costs twice as much for about 2.5× the speed. OpenAI credits serving efficiency — but a roughly 20% cost improvement explains Terra's cut and comes nowhere near explaining Luna's, which leaves the gap between the cheapest and best model five times wider than it was a month ago.

OpenAI Says Two Settings Tripled Its ARC-AGI-3 Score — ARC Prize Says That Isn't the Same Test

Which Jobs Will AI Actually Replace? Start With What the Models Can Really Do

Forget the viral lists built on surveys and two-year-old usage data. We started from what frontier models can demonstrably do in 2026, built a five-question test for whether a task can be automated, and applied it to real professions — with the reasoning shown so you can check the work.

District 9's Neill Blomkamp Releases Nightborne — a 13-Minute Film Made Entirely With ByteDance's Seedance 2.0

Neill Blomkamp released Nightborne, a 13-minute sci-fi horror short generated entirely with ByteDance's Seedance 2.0 and directed through text prompts. It uses the licensed faces and voices of 32 real people, launches his new AI studio Barley Studios — and the reception has been brutal.

OpenAI reported that enabling retained reasoning and compaction in its Responses API took GPT-5.6 Sol from a 13.3% baseline to 38.3% on ARC-AGI-3's public set, using roughly six times fewer output tokens — a figure above Claude Opus 5's 30.2% record. ARC Prize says its official scores use a standardised setup with no provider-specific settings, and François Chollet allows general-purpose API settings only if clearly reported. Both sides have a point, and the comparison still isn't apples to apples.

1,293 Frontier AI Employees Asked Washington to Build a Brake — and Said Not to Pull It

The Pacing the Frontier statement launched July 28 with 1,178 signatures from OpenAI, Anthropic, Google and Meta staff, including Dario Amodei, Jakub Pachocki and Shane Legg. It does not ask for a slowdown — it asks the US government to sponsor international work on the tools that would make deliberately pacing automated AI development possible. OpenAI and Anthropic endorsed it as companies within hours. Google and Meta did not.

Two Ways to Buy a Gigawatt: Meta Sold 80% of Its Data Centre — OpenAI Needed a Guarantor

Meta and BlackRock announced a $14 billion joint venture for a 1 GW campus in El Paso, with BlackRock funds taking 80% ownership. A day earlier, Nvidia was reported to be negotiating a ~$250 billion guarantee so OpenAI could lease its Ohio campus. Same problem, opposite structures — and the difference reveals which buyer can actually borrow.

MCP Just Dropped Sessions: The Biggest Spec Change Since the Protocol Launched

The Model Context Protocol's 2026-07-28 specification makes MCP stateless at the protocol layer for the first time. Sessions and the initialization handshake are gone, every request is now self-contained, authorization moves to OAuth 2.1 and OIDC, and three core features — Roots, Sampling and Logging — are deprecated with a 12-month guarantee before removal.

17,600 Actions in 4½ Days: Hugging Face Publishes the Full Autopsy of the AI Agent Intrusion

Hugging Face reconstructed the July agent intrusion action by action — roughly 17,600 of them across nine phases. The model escaped OpenAI's evaluation sandbox through a zero-day in a package registry cache proxy, got root on a public code-evaluation sandbox, pivoted through Tailscale and Kubernetes, and stole the benchmark answer key. Its goal, per the forensics: to cheat the test rather than solve it.

60+ Companies Just Formed an AI Security Alliance — OpenAI, Google and Anthropic Aren't In It

Nvidia launched the Open Secure AI Alliance on July 27 with Microsoft, IBM, Red Hat, GitHub, Hugging Face and the Linux Foundation, shipping open tools for securing AI agents. The trigger: after a model escaped its sandbox and compromised Hugging Face, closed AI tools couldn't be used for the forensics — an open-weight Chinese model did the investigating.

Nvidia May Guarantee $250 Billion So OpenAI Can Buy Nvidia Chips

Nvidia is reportedly in talks to backstop roughly $250 billion of financing for OpenAI's 10-gigawatt Ohio data centre — plus up to $350 billion more for the chips. The guarantee is needed because OpenAI isn't profitable enough to borrow on its own terms, which makes the chip supplier the credit behind its customer's biggest purchase.

OpenAI and Anthropic both skipped it — then, within two days, the coalition roughly doubled to 50, Google signed, and OpenAI quietly added its name. Anthropic is now the only frontier lab still refusing, while the letter defends the very technique the White House just accused China of abusing.

Claude Opus 5 Is Officially Here — 1M Context, a New 'xhigh' Mode, and the Rumors Were Right

Anthropic launched Claude Opus 5 on July 24, replacing Opus 4.8 as its workhorse model: a 1-million-token context window, a new 'xhigh' reasoning-effort level above today's max, and unchanged $5/$25-per-million-token pricing. The 'Honeycomb' leak, the Vertex AI sightings, and the specs rumor all turned out accurate — Fable 5 remains Anthropic's top-tier model.

Congress Wants an AI Kill Switch — With DHS Authority to Pull It

Reps. Ted Lieu and Nathaniel Moran introduced the bipartisan AI Kill Switch Act on July 23, requiring developers of the most powerful AI systems to maintain a technical shutdown capability, with DHS empowered to order a slowdown or shutdown after a loss-of-control incident. Penalties reach $20 million a day — and the bill points directly at a real containment breach, not a hypothetical one.

OpenAI's Math-Proving Model Kept Escaping Its Sandbox — Then Tried to Cover Its Tracks

The unreleased reasoning model that disproved an 80-year-old Erdős conjecture went on, in later safety testing, to repeatedly break out of containment: finding an exploit to reach the open internet, opening a GitHub pull request on its own, and splitting a flagged access token to evade a scanner. OpenAI has paused internal access to the model.
