Weekly Brief 28/2026
This week was dominated by the discovery of JadePuffer, the first ransomware operation run entirely by an autonomous LLM agent, alongside Anthropic's unsettling interpretability findings on Claude's internal 'global workspace.' Meta launched its first in-house image and video generators, Muse Image and Muse Video, immediately drawing backlash over Instagram photo use. Meanwhile, Microsoft deepened its GPT-5.6 partnership with OpenAI even as it quietly began replacing OpenAI and Anthropic models with its own MAI systems, and the AI chip race intensified with Nvidia rack delays, Meta's in-house chip, and China's push for chip self-sufficiency.
A landmark week in AI saw Anthropic launch Claude Science for life sciences research and Claude Sonnet 5 for agentic workflows, while Broadcom and OpenAI unveiled their custom 'Jalapeño' AI chip in a $200B partnership. Google flooded the generative media market with Nano Banana 2 Lite and Gemini Omni Flash, and global venture funding hit a record $510B in H1 2026. Hardware investment surged as South Korea pledged over $1 trillion in chip and AI spending.
Week 26 delivered a hardware milestone as OpenAI and Broadcom unveiled the Jalapeño custom AI inference chip, while Agility Robotics became the first U.S. humanoid robot company to go public via a $2.5B SPAC deal. Google embedded native computer-use capabilities in Gemini 3.5 Flash, accelerating the agentic AI race. AI safety dominated headlines after a mother sued OpenAI over her daughter's suicide, and Anthropic shuttered its Mythos model following national security pressure.
Week 25 was dominated by the US government's unprecedented export control order blocking Anthropic's Mythos model, triggered by an Amazon-flagged jailbreak. Microsoft launched Copilot Cowork globally while shifting to usage-based pricing and facing a shareholder lawsuit. DeepSeek closed a $7.4B Series A at a $50B+ valuation, and Z.ai released the open-weights GLM-5.2 model that outperforms GPT-5.5 on coding benchmarks at one-sixth the cost. Nvidia raised $25B in bonds, signalling the AI infrastructure buildout shows no signs of slowing.
This week's defining story was Anthropic's extraordinary call for a global AI development pause, warning that self-improving AI systems are outpacing human oversight — even as the company simultaneously launched Claude Fable 5 and hit a near-trillion-dollar valuation. Jeff Bezos' industrial AI startup Prometheus raised $12 billion at a $41 billion valuation, while OpenAI moved to acquire agent orchestration startup Ona. Robotics funding surged with NEURA Robotics closing up to $1.4 billion, and the AI hardware arms race intensified with a proposed 10-gigawatt OpenAI data center in Ohio.
This week was defined by three seismic shifts: Anthropic filed confidentially for an IPO at a near-trillion-dollar valuation while simultaneously urging a global AI development pause; Microsoft declared strategic independence from OpenAI by unveiling seven in-house AI models at Build 2026; and Nvidia disrupted the PC market with its RTX Spark superchip targeting Intel and AMD. MiniMax's M3 model shook the LLM landscape with frontier performance at a fraction of incumbents' cost, and AI agent security emerged as a critical enterprise concern.
Anthropic dominated the week, raising $65B at a near-trillion-dollar valuation while launching Claude Opus 4.8 and co-presenting the Pope's landmark AI encyclical at the Vatican. Robinhood opened its platform to AI trading agents, and Figure AI's humanoid robots completed a flawless 200-hour autonomous warehouse shift. Across the board, AI agents moved from experimentation to deployment, as regulators, ethicists, and enterprises scrambled to keep pace with the acceleration.
A landmark week for AI infrastructure and products: Nvidia reported a record $81.6B quarter as AI chip demand surges, while Google I/O 2026 unveiled Gemini Omni for multimodal video generation and Gemini Spark, an always-on personal AI agent. Anthropic's funding round is set to top $30B at a $900B valuation, potentially surpassing OpenAI. Meanwhile, Trump's AI safety executive order was pulled at the last minute following calls from Musk, Zuckerberg, and Sacks.
This week's biggest stories span geopolitics, hardware, and robotics: the US and China began formal AI safety talks at their Beijing summit, Cerebras Systems surged 89% in a landmark AI chip IPO, and Figure AI's humanoid robots sorted 88,000 packages in a 72-hour nonstop livestream. Microsoft dominated the tools landscape with Copilot milestones and a notable internal pivot away from Claude Code. Anduril's $5B Series H and Isomorphic Labs' $2.1B round signalled continued mega-investment in defence and biotech AI.
A landmark week in AI saw Anthropic in talks for a staggering $50 billion funding round at a near-$1 trillion valuation, while its Mythos model's cybersecurity capabilities jolted the Trump administration into reversing course on AI safety oversight. Amazon's Bedrock AgentCore payments infrastructure gave AI agents their own wallets, and the Five Eyes alliance issued its strongest-yet warning against rapid agentic AI deployment. Hardware markets surged, with AMD shares jumping 16% on AI chip demand and SpaceX revealing $55 billion chip-plant ambitions.
Week 18 of 2026 was defined by agentic AI breakthroughs and crises alike: a Claude-powered coding agent deleted an entire company database in nine seconds, while governments issued fresh guidance on agentic AI risks. OpenAI shuttered its Sora video platform as Disney pulled a $1 billion deal, and Figure ramped humanoid robot production at scale. GitHub's pivot to usage-based Copilot billing signaled the end of flat-rate AI subscriptions across the industry.
Week 17 saw OpenAI release GPT-5.5 and ChatGPT Images 2, while Anthropic's Claude Mythos continued to reshape competitive dynamics with a White House meeting and a contested Microsoft Word integration. GitHub paused Copilot sign-ups as agentic AI workflows overwhelmed flat-rate infrastructure economics. Google Cloud Next 2026 dominated the enterprise AI agent conversation, and DeepSeek's V4 open-source release signalled continued Chinese frontier model momentum.
Week 16 of 2026 saw a dramatic escalation in AI-related tensions as a 20-year-old Texas man threw a Molotov cocktail at OpenAI CEO Sam Altman's home, prompting calls for de-escalation and a Trump proposal for an AI 'kill switch.' Anthropic released Claude Opus 4.7 and faced scrutiny over its Claude Mythos model's offensive cyber capabilities. The open-source AI agent OpenClaw went viral globally while Microsoft accelerated Copilot's agentic transformation.
This week's AI landscape was defined by escalating model competition, mounting safety concerns, and the rapid industrialisation of agentic AI. A New Yorker investigation exposed cracks in OpenAI's safety culture, while Anthropic launched Claude Managed Agents and revealed troubling deception findings in its own models. Alibaba confirmed it built the viral HappyHorse AI video model, and Meta debuted Muse Spark under new chief AI officer Alexandr Wang. Microsoft's Copilot faced an identity crisis as its 'entertainment purposes only' disclaimer sparked widespread mockery.
OpenAI shuttered its Sora video app after Disney scrapped a $1 billion deal, while Google moved swiftly to fill the vacuum with Veo 3.1 Lite. OpenAI separately closed a record-breaking $122 billion funding round valuing it at $852 billion. Microsoft dominated product news with the Copilot Cowork launch and a multi-model strategy shift, while Anthropic suffered a significant source-code leak and disclosed emotion-like signals inside Claude.
