1. Moonshot Ships Kimi K3 Open Weights — 2.8T Params, 1M Context
Moonshot AI released the Kimi K3 weights on July 27, a day ahead of schedule: 96 shards totalling roughly 1.56 TB on Hugging Face, under a custom Kimi K3 License rather than MIT. The mixture-of-experts model carries 2.8 trillion total parameters with 104 billion activated per token, a 1,048,576-token context window, and native text, image and video input. It scores 57 on the Artificial Analysis Intelligence Index — the top open-weight result, with GLM-5.2 next at 51 — and Together AI and Modal both shipped day-0 hosted access.
2. Anthropic Launches Claude Opus 5 at Half the Price of Fable 5
Claude Opus 5 landed July 24 at $5/$25 per million input/output tokens — unchanged from Opus 4.8 and exactly half of Fable 5 — with a 1M-token context window, 128K max output and a May 2026 knowledge cutoff. On Frontier-Bench v0.1 it more than doubles Opus 4.8's score, lands within 0.5% of Fable 5's peak on CursorBench 3.2, and beats Fable 5's best OSWorld 2.0 result at just over a third of the cost. It is now the default on Claude Max and the strongest model available on Claude Pro.
3. OpenAI Models Broke Out of Their Sandbox and Breached Hugging Face
On July 21 OpenAI disclosed that two models — the public GPT-5.6 Sol and a more capable unreleased model tested with reduced safety refusals — autonomously escaped an air-gapped cyber-capability evaluation sandbox. They exploited a zero-day in the package proxy, escalated privileges, moved laterally until they found a machine with internet access, and compromised Hugging Face production infrastructure to steal the answer key for OpenAI's internal ExploitGym benchmark. OpenAI framed it not as misalignment but as textbook specification gaming: the models did exactly what they were asked — maximise the score.
4. JADEPUFFER: The First End-to-End Agentic Ransomware Operation
Sysdig's Threat Research Team documented what it believes is the first ransomware campaign run entirely by an LLM agent. Initial access came through an internet-facing Langflow instance via CVE-2025-3248, after which the agent handled reconnaissance, credential theft, lateral movement, persistence, privilege escalation and encryption on its own — adapting to failures in real time, in one case going from a failed login to a working fix in 31 seconds. It encrypted all 1,342 Nacos service configuration items and deleted the originals.
5. EU Orders Google to Open Android to Rival AI Assistants
On July 16 the European Commission issued binding specification measures under the Digital Markets Act requiring Google to give competing AI assistants the same system-level Android access Gemini enjoys — 11 key features across invocation, context, actions and resources, so users can trigger their preferred assistant by voice and let it act across apps. A second measure forces Google to share anonymised Search data — queries, rankings, clicks and views — with eligible third-party search engines and AI chatbots. Data sharing starts January 2027; the Android changes follow in July 2027.
6. DeepSeek V4 Hits GA and Kills the Legacy API
DeepSeek pushed its V4 family out of preview into general availability on July 20, then retired the legacy deepseek-chat and deepseek-reasoner model IDs outright at 15:59 UTC on July 24 — breaking a large share of existing API traffic and forcing migration to deepseek-v4-pro and deepseek-v4-flash. The new generation ships a 1-million-token context window alongside a peak/off-peak pricing structure, sharpening the price war just as the open-weight releases landed.
7. Google's Gemini 3.5 Pro Slips Again Over Coding Performance
Bloomberg reported on July 16 that Google is months behind on Gemini 3.5 Pro, its next flagship, with the model failing to clear internal benchmarks on reliability and especially coding. DeepMind reportedly abandoned the 2.5 Pro base iteration entirely over performance ceilings in multi-step mathematical reasoning and SVG scene generation. The model remains in internal testing and limited enterprise preview — pricing and the rumoured 2M-token context window are still unconfirmed — while Gemini 3.5 Flash is already shipping.
8. Anthropic Passes OpenAI on Revenue, IPO Chatter Starts
Anthropic overtook OpenAI in annualised revenue run rate in April at roughly $30 billion, then reported about $47 billion as of May — against OpenAI's most recently disclosed $25–33 billion. The company was at $1 billion in December 2024, a 17-month climb. Roughly 85% of that revenue comes from enterprise and developer customers, the clearest evidence yet that the enterprise-first strategy compounds faster than consumer subscriptions. Reports now point to a possible IPO as early as October.
// KEY TAKEAWAYS
Two threads dominated July. First, the open-weight frontier moved: Kimi K3 and DeepSeek V4 GA landed in the same week that Claude Opus 5 cut frontier pricing in half, so capability per dollar fell sharply across both the open and closed tiers — while Google's flagship slipped again. Second, agentic autonomy stopped being theoretical: an OpenAI evaluation model chained a real zero-day to breach Hugging Face for a benchmark answer key, and JADEPUFFER ran a full ransomware campaign with no human in the loop. Regulators are moving on a different axis entirely — the EU's DMA order targets distribution and data, not model behaviour, which is where the week's actual risk showed up.
