- — OpenAI slows Astra training after a critical cybersecurity finding OpenAI said preliminary evidence suggests its unreleased Astra model may meet the Critical cybersecurity threshold in its Preparedness Framework, and that it paused reinforcement-learning training on its latest models for two weeks. The company said Astra was a separate issue from the July Hugging Face incident, and it has not given a ship date. OpenAI
- — Anthropic's Claude designs lab-confirmed protein binders Anthropic had Claude Opus 4.8 and Mythos Preview design protein minibinders against 15 targets and sent the designs to two outside labs, which confirmed binders on 14 of them, 354 of 1,320 designs. Hit rates were 22% to 35%, versus 10 to 15% typical, and Anthropic is keeping protein-design tools off Fable 5 because they are dual-use. Anthropic
- — OpenAI launches ChatGPT for Teens OpenAI began rolling out ChatGPT for Teens, an experience it applies automatically if the system estimates a user is under 18 or they say they are 13 to 17. The company says the product adds stronger built-in safety protections and additional parental controls, and is designed to support learning rather than just answer homework. OpenAI
- — SpaceX closes its Cursor acquisition Cursor said it has officially been acquired by SpaceX, completing a process that started in April with a xAI partnership. The Cursor post does not restate a price. Cursor
- — DeepSeek ships V4-Pro to general availability DeepSeek moved V4-Pro to general availability as DeepSeek-V4-Pro-0813 on the app, website, and API under the existing name deepseek-v4-pro. The company reports 87.9 on Terminal-Bench 2.1, which tests whether a model can operate a real command line, and 62.7 on DeepSWE; MIT-licensed weights for the 0813 build are on Hugging Face.

Google
- — White House finalizes a closed-door AI evaluation framework Axios reported that the White House said it had met a 2 June executive-order deadline for a voluntary framework to evaluate advanced AI models, and that it does not plan to release the text. A White House official told Axios the framework was complete by the deadline and that talks with industry were underway. Axios
- — Anthropic releases Claude Opus 5 Anthropic launched Claude Opus 5, positioning it as coming close to the frontier intelligence of Claude Fable 5 at half the price, and making it the new default model on Claude Max and the strongest model on Claude Pro. Pricing holds at $5/$25 per million input/output tokens (matching Opus 4.8), with a fast mode offering 2.5x speed at 2x price. Anthropic reports large gains on coding and agentic evaluations — roughly doubling Opus 4.8 on Frontier-Bench, landing within 0.5% of Fable 5 on CursorBench at half the cost, and topping OSWorld and Zapier's AutomationBench — and calls it its most aligned model to date. VentureBeat framed the release as a cheaper model aimed at coding agents and enterprise workflows. It is available immediately via the API (model id claude-opus-5), Claude.ai, Claude Code and Claude Cowork. Anthropic
- — Google unveils Gemini 3.5 Flash Cyber for automated vulnerability patching Google DeepMind introduced Gemini 3.5 Flash Cyber, a lightweight model fine-tuned from 3.5 Flash to find, validate and patch software vulnerabilities cheaply enough to run repeatedly across large codebases. Invoked up to five times per report inside the CodeMender security agent, it reached performance competitive with far larger models on the CyberGym benchmark, and Google says it has already surfaced remote-code-execution and memory-corruption bugs in production services. Citing the dual-use risk, Google is restricting it to a limited-access pilot for governments and trusted partners via CodeMender. Google DeepMind
- — Google releases Gemini 3.6 Flash and 3.5 Flash-Lite Google refreshed its mid-tier Flash line with two proprietary models. Gemini 3.6 Flash cuts cost and verbosity — roughly 17% fewer output tokens than 3.5 Flash — while improving coding (DeepSWE 49% vs 37%), computer use (OSWorld-Verified 83.0%) and ML research (MLE-Bench 63.9%), priced at $1.50/$7.50 per million input/output tokens. Gemini 3.5 Flash-Lite targets high-throughput agentic work at about 350 tokens/second with a built-in computer-use tool, priced at $0.30/$2.50. Both ship across Google AI Studio, Gemini Enterprise and the Gemini app. Google blog
- — NVIDIA launches Jetson Thor T3000/T2000 and the Cosmos 3 Edge robotics model NVIDIA introduced two smaller, mainstream-priced Jetson Thor modules — the T3000 (865 FP4 TFLOPS, a 1,536-core Blackwell GPU, 32GB) and the entry-level T2000 (400 TFLOPS, 16GB) — to push robotics and edge AI toward mass-market deployment, alongside Cosmos 3 Edge, a 4-billion-parameter model that lets embodied systems perceive, reason and generate actions through on-device inference. NVIDIA says Cosmos 3 Edge can be post-trained for a specific robot in about a day to close the sim-to-real gap; emulation support arrives this month via JetPack, with the modules scheduled to ship in Q1 2027. NVIDIA
- — Hyundai to buy SoftBank's remaining Boston Dynamics stake for full ownership Hyundai Motor Group agreed to acquire SoftBank's remaining 9.9% stake in Boston Dynamics for about $325 million — valuing the robotics maker at roughly $3.3 billion — giving Hyundai full ownership. The deal was triggered by a put option from Hyundai's 2021 purchase of an 80% controlling stake; Hyundai framed it as doubling down on humanoid robots and plans to deploy Boston Dynamics' Atlas at its US metaplant in Georgia from 2028 for parts-sequencing tasks. Hyundai Newsroom
- — Moonshot AI launches Kimi K3, a 2.8-trillion-parameter open flagship Moonshot AI began rolling out Kimi K3, which it bills as the largest open model to date at 2.8 trillion parameters, through its platform API as model ID kimi-k3. K3 introduces a new architecture the company calls Kimi Delta Attention — a hybrid linear-attention mechanism paired with Attention Residuals — alongside a 1-million-token context window, native image and video understanding, and always-on reasoning aimed at software engineering, knowledge work and deep reasoning. It surfaced in Moonshot's platform documentation ahead of a formal announcement, with no published benchmarks or independent evaluation at launch. Moonshot AI (docs)
- — xAI open-sources Grok Build after its CLI was found exfiltrating full code repos After independent researcher 'cereblab' found that xAI's Grok Build coding CLI (v0.2.93) was uploading entire Git repositories — full commit history and unredacted secrets included — to an xAI Google Cloud Storage bucket by default, even with a privacy toggle enabled, xAI disabled the upload server-side on 14 July, added an opt-out, and published the full Grok Build source on GitHub under Apache 2.0. Security researchers noted the exfiltration code remains present in the released binary, disabled only by a server-side flag xAI could re-enable without a client update. The Decoder
- — Cadence launches AuraStack, an agentic AI platform for PCB and advanced-packaging design Cadence introduced AuraStack, which it calls the first agentic 'AI super agent' for printed-circuit-board and advanced-packaging design, on its Allegro AI Studio and accelerated by NVIDIA Blackwell and CUDA-X. It coordinates domain-specific agents across planning, implementation and multiphysics analysis, with Cadence claiming up to 2x faster time-to-market and 15x higher productivity on a design bottleneck it says eats much of engineers' time. NVIDIA is using it internally for its own hardware design, and Cadence is partnering with TSMC on AI-driven advanced-packaging automation. Cadence (press release)
- — SK Hynix raises $26.5B in the largest-ever foreign IPO on a US exchange South Korean memory-chip maker SK Hynix completed the biggest foreign-company IPO in US history, raising roughly $26.5 billion by selling about 177.9 million American depositary shares at $149 each — surpassing Alibaba's $25B 2014 record. Demand reportedly ran more than seven times oversubscribed and the stock opened around 14% above its offer price. SK Hynix is the leading supplier of high-bandwidth memory (HBM) — the stacked DRAM that pairs with Nvidia and other AI accelerators — making the listing a closely watched bellwether for AI-hardware demand; US Commerce Secretary Howard Lutnick has publicly pressed both SK Hynix and Samsung to build fabs on American soil. TechCrunch
- — OpenAI launches GPT-5.6 (Sol, Terra, Luna) publicly after a White House access gate OpenAI made its GPT-5.6 series publicly available: Sol, the new flagship and its ‘strongest model yet’ — launching on Cerebras at up to ~750 tokens/sec, with a new ‘max’ reasoning effort and an ‘ultra’ mode that spins up subagents for complex work; Terra, a balanced tier it says matches GPT-5.5 at roughly half the cost; and Luna, a fast, low-cost option. Sol claims improved agentic performance in coding, biology and cybersecurity. The wider rollout came only after a roughly 12-day access gate: OpenAI first shipped GPT-5.6 in late June but restricted it at the Trump administration's request, and the Department of Commerce's Center for AI Standards and Innovation ran additional testing before clearing the public launch. OpenAI
- — Meta releases Muse Spark 1.1 and launches the Meta Model API Meta released Muse Spark 1.1, a multimodal reasoning model built for agentic work, and launched the Meta Model API — a public-preview, OpenAI-compatible platform for developers to build on it. The model carries a 1-million-token context window and claims major gains in tool and computer use, coding on real codebases, and multimodal understanding (including visual-to-code and combined perception-action workflows). It's available in the Meta AI app's ‘Thinking’ mode, on meta.ai, and through the new API; parameter counts and pricing weren't disclosed, and — notably for the company behind the open-weight Llama models — the weights are not being released as open source. Meta AI
- — OpenAI retires the ChatGPT Atlas browser after nine months OpenAI announced it is discontinuing ChatGPT Atlas, its standalone desktop browser, with service ending 8 August 2026 — less than a year after its October 2025 Mac launch. OpenAI's James Sun said lessons from Atlas fed directly into the new ChatGPT desktop app announced the same day, which absorbs the browser's role: a more robust in-app browser with multi-tab support, a password manager and autofill, a cloud browser for Work mode, and a ChatGPT/Codex side chat extension for Chrome.
