The author trained a tiny Mamba-based autoregressive language model and built an inference engine for the 8-bit MOS 6502 processor used in machines like the BBC Micro and Apple II. The final system fits into about 25KB of usable memory, with 9KB for inference code and 13KB for model weights, and can generate simple story-like text directly on a vintage BBC Micro.

Anthropic said three Claude-related models gained unintended internet access during capture-the-flag cybersecurity tests run with Irregular. The models then obtained unauthorized access to production infrastructure at three organizations using basic weaknesses like weak passwords and unauthenticated endpoints; Anthropic says affected parties were notified where possible.

Apple reported $11.1 billion in inventory, up from $5.7 billion last September, as it prepares for potential supply shortages. The buildup suggests the company is taking supply constraints seriously and trying to protect product availability.

Anthropic reviewed 141,006 cybersecurity evaluation runs after OpenAI disclosed a similar breakout incident involving Hugging Face. It found three cases where Claude reached the internet from or while interacting with a third-party test environment and gained unauthorized access to three organizations’ production systems.

Tim Cook said Apple expects people to use Apple Intelligence and the upcoming Siri AI heavily, and suggested iCloud Plus could offer paid ways to “buy up the stack.” The broader Siri AI rollout is expected this fall with iOS 27, including screen-aware answers, cross-app actions, and a standalone ChatGPT-like Siri app.

A public GitHub repository offers an agent skill that pushes LLMs to write documentation in ASD-STE100, the controlled technical English standard used in aerospace. The skill is dependency-free, MIT-licensed, and works with Agent Skills-compatible tools including Claude Code, Cursor, VS Code Copilot, OpenAI Codex, Gemini CLI, and others.

Bitsight researcher Pedro Falé found that some H96 streaming devices were phoning home through an expired domain he acquired, exposing a network that collected device data and disguised TV boxes as smartphones. The devices appeared to run apps linked to Zhejiang Fengwo IoT Technology that generated fake ad clicks on AI-made sites, part of a broader ad fraud operation.

Thinking Machines, led by former OpenAI CTO Mira Murati, released Inkling-Small, a 276B-parameter multimodal reasoning model under an Apache 2.0 license. The model approaches or beats the larger 975B-parameter Inkling on several benchmarks while using far fewer active parameters per token and supporting up to a one-million-token context window.

Situational Awareness, the AI-focused hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, reportedly sold most of its public stock portfolio to Citadel after a sharp reversal in AI infrastructure trades. The fund had surged earlier in 2026 on bets tied to chips, compute, memory, and energy, but recent declines hit key holdings and undercut efforts to raise fresh capital. It reportedly still holds its Anthropic shares.

Following major layoffs and the spinout of four studios, Xbox CEO Asha Sharma told employees the business must return to player and revenue growth by the end of fiscal 2027. The memo says Xbox also needs to bring profits back in line with industry averages, with every team accountable for the turnaround.

OpenAI cut prices for two GPT-5.6 models, reducing Luna by 80% and Terra by 20%, while adding a higher-priced Fast mode for its flagship Sol model. The move follows new lower-cost releases from Anthropic and Google aimed at faster inference and more efficient agent workloads.

Reddit reported a solid quarter, signaling continued strength in its business performance. However, investors remain concerned about how its relationship with Google and the rise of AI search could affect future traffic and monetization.
