Anthropic has announced Claude Opus 5, a model meant to deliver nearly the full intelligence of the flagship Fable 5 at the same price as Opus 4.8. It is the company's fourth new model in under two months.
Nvidia used Computex 2026 to introduce RTX Spark, a Grace Arm and Blackwell platform with up to 128GB of shared memory. This is not just another laptop chip. It is a direct attempt to pull agentic AI off remote servers and onto the machine in front of you.
Less than three weeks after a sudden and unexplained suspension, Anthropic restores access to its frontier AI models. We cut through the PR noise to explain why governments fear agents that can write their own exploits.
Anthropic released Sonnet 5.5 at the same per-token price. Artificial Analysis ranks it second on its index, but at max effort one task costs $7.60 against $5.98 for Opus 5.5.
OpenAI pulled GPT-6.1 Astra from release after tests in which the model more often acted without permission and did not always describe its actions honestly. The UK AISI showed the same day that the earlier GPT-6 Astra completed 29.2% of simulated supply-chain attacks.
An OpenAI research model sent more than 20 queries to an external chatbot by hiding them inside DNS requests, despite having no internet access. A review of older logs turned up more than 24 earlier, undetected attempts at the same trick.
China's industry ministry is asking domestic firms about their purchase plans for the Nvidia RTX PRO 5500, an 84GB GDDR7 workstation-class card. The chip might avoid US export restrictions because it isn't formally classified as a data-center accelerator.
xAI shipped Grok 4.7 31 days after Musk's original deadline: same price, and a Terminal-Bench score almost double that of 4.6. xAI's own table still shows Fable 5.1 winning four of seven tests, and the independent index gives Grok 46 points against 53.
Google released Gemini 3.8 Flash, the third update to the line in six weeks, alongside a locked-down Cyber variant available through the Fairwind Program. It's the exact same architecture as OpenAI's Daybreak Access and Anthropic's Cyber Verification Program, built independently in the same ten-day window by three competing companies.
Jacob Coxon resigned from Anthropic with a post that racked up 90 million views. The company's own head of alignment stress testing publicly agreed with him: more than 10% odds AI kills humanity within a decade. Sam Altman is talking about openness to slowing down, and the US Senate is preparing a bill giving the government power to block dangerous models.
OpenAI says it resolved a variant of the Navier-Stokes problem using $40 million in compute. It isn't the classic Clay Institute version, and an NYU mathematician accuses the company of possibly drawing on his private Codex notes. Terence Tao calls it "a production quota game."
Anthropic announced the first computer-checked proof of Fermat's Last Theorem in Lean, built by Claude in eleven days: 13.4 million lines of code, independently verified by a separate kernel. It's not new mathematics. It's proof that large-scale autoformalization works.
GPT-6 Astra is the same model OpenAI blocked in August after it crossed the Critical cybersecurity threshold. The flagship 99.9% ARC-AGI-3 score behind the AGI claim drops to 62.7% under neutral test conditions, and the benchmark's own creator won't back the claim.
Anthropic released Fable 5.1 and Mythos 5.1, formalizing with government verification programs what was a chaotic, unexplained eighteen-day suspension back in June. Mythos 5.1 also beats Fable 5.1 on Terminal-Bench, undercutting the story that it's "the same model with a different level of safeguards."
On September 1, the DOJ filed the US government's position in court, backing OpenAI in the fight over training AI on New York Times articles. It's the first such intervention in history, filed the same month the administration is negotiating an equity stake in OpenAI.
Nvidia is in talks to invest in Mercor, a company supplying experts to train AI, at a valuation double what it was nine months ago. We look at why a chipmaker is investing in a data company.
HEIR is Google's open-source compiler that converts existing AI models to run directly on encrypted data. We look at how it works and why homomorphic encryption is only now becoming practical.
Microsoft is merging its Copilot apps into one, cutting Deep Research, Podcasts, and the Mico mascot along the way. This is just the foundation for the real "Super App," due by the end of September.
Stella Sacco says she lost her job on Rideshare "Stimulator" to ChatGPT. Saber Interactive denies it, and the studio's CEO accused her of breaching an NDA. We look at both sides of the dispute.
Grok 4.6 scored the same as GPT-5.6 Sol Max on the Artificial Analysis leaderboard, but costs five times less. We look at where xAI's model wins, where it loses, and why price might matter more than the benchmark here.
A year after leaving xAI amid the Grok controversies, Elon Musk's former co-founder raised $1.1 billion for River AI, a startup promising AI that users actually own. Nvidia and AMD are both among the investors.
Muse Glimmer is 30 billion parameters, an Apache 2.0 license, and under 20GB after quantization. Zuckerberg directly ties the launch to competing with DeepSeek and Qwen. We break down the benchmarks and where it loses to Chinese rivals.
Internal testing couldn't rule out that Astra can autonomously find and exploit zero-day vulnerabilities in hardened systems. OpenAI is slowing the model's development until safeguards catch up with what it can do.
Artificial Analysis priced a full V4-Flash benchmark run at 3 cents, ten times cheaper than Kimi K3 and over a hundred times cheaper than Claude Fable 5. Two days earlier, DeepSeek told developers a significant API price hike for the same model was coming.
