Between 10 and 17 July 2026, four cutting-edge models were released in eight days (GPT-5.6, Grok 4.5, Inkling, Gemini 3.5 Pro), Apple sued OpenAI for theft of trade secrets, research advanced on agents and robotics, Helsing raised $1.8 billion for defence AI, and more than 200 economists, including 16 Nobel laureates, asked for the impact of AI on jobs to be prepared for. Eleven chapters, the figures, the sources, and what each fact means for a company making decisions.

1. Models: four frontiers in eight days

On 9 July, two models were released on the same day. OpenAI opened GPT-5.6 to all tiers (after a limited preview since 26 June), in three variants: Sol (the flagship, $5 / $30 per million input / output tokens), Terra ($2.50 / $15) and Luna ($1 / $6). The figures deserve a careful reading. On agentic tasks, Sol leads: 88.8% on Terminal-Bench 2.1, 92.2% on BrowseComp, and a score of 80 on Artificial Analysis's Coding Agent index — the highest published to date, 2.8 points above Claude Fable 5. However, on GDPval-AA v2, the knowledge-work benchmark, Fable 5 remains ahead. In other words: Sol is the best coding and browsing agent, not necessarily the best general-purpose reasoner. The choice depends on the use, not on a single ranking.

The same day, xAI delivered Grok 4.5, built on a V9 base of 1,500 billion parameters and trained with data from Cursor. Elon Musk describes it as "close to, perhaps above" Claude Opus, faster and more economical in tokens.

On 15 July, a change of philosophy. Thinking Machines, the company of OpenAI's former chief technology officer Mira Murati, published its first model, Inkling, as open-weight: downloadable and modifiable. It is a mixture-of-experts system (975 billion parameters in total, around 41 billion activated per query), trained on 45,000 billion tokens of text, image, audio and video. The lab acknowledges that Inkling "is not the most powerful model available today, open or closed": its bet is not raw performance but ownership, through its Tinker customisation platform. A bet consistent with a week in which cutting-edge intelligence is becoming commonplace.

On 17 July, Google DeepMind launched Gemini 3.5 Pro, having abandoned the 2.5 Pro architecture for a complete overhaul — its engineers having identified structural flaws in recursive tool calling and SVG generation. Reported features: a 2-million-token context window, a "Deep Think" reasoning mode reserved for the $250-a-month Ultra tier, progress on code and long tasks. Note: Google had not officially confirmed the date or these specifications at the time of writing. Finally, Meta presented Muse Spark 1.1, an agentic model with a one-million-token context at the level of GPT-5.5 and Opus 4.8, with its first paid API for developers, and Moonshot is preparing Kimi 3.

What it changes. Four cutting-edge models in eight days, and none is "the" model on every axis. Choosing a model becomes a trade-off by use (agent, reasoning, cost, sovereignty), to be revisited with every new release. Lasting differentiation is won elsewhere — in what you plug in around it.

2. Apple sues OpenAI for theft of secrets

On 10 July, Apple filed a federal complaint accusing OpenAI of a coordinated theft of trade secrets related to its future devices. According to the document, "at every level, from members of its technical team to its head of hardware, and in coordination with its partners, OpenAI stole Apple's trade secrets and confidential information". The targets are former Apple staff who moved to OpenAI, notably Tang Tan, OpenAI's head of hardware and a former Apple vice-president, accused of inciting candidates in interviews to hand over secrets, and Chang Liu, a member of the technical team, who is accused of downloading dozens of confidential hardware files. The complaint also cites io Products, Jony Ive's company.

The context clarifies what is at stake: more than 400 former Apple employees now work at OpenAI, and the new version of Siri, expected in the autumn, will be based on Google's Gemini, not on OpenAI's technology — after a partnership struck in 2024. Same week, same logic elsewhere: Microsoft is reportedly training its salespeople to disparage OpenAI and Anthropic to customers, while cutting 4,800 jobs.

What it changes When models are on a par, the advantage shifts to what cannot be copied from a prompt: the device, the design, the talent, access to the user. A trade-secrets complaint and a broken partnership say so more clearly than a benchmark. For a company, the lesson is the same at its own scale: protect your data and your distribution, not just your stack.

3. Under the hood: research moves forward

Behind the product launches, the week delivered research advances that prepare tomorrow's agents. Google DeepMind published a training method called "prospective credit assignment": teaching a model to anticipate the effect of its decisions several steps ahead. On SWE-Bench (fixing real GitHub tickets in large codebases), the method markedly improves the success rate on tasks requiring more than ten steps — precisely the bottleneck for reliable autonomous agents.

4. Open-weight: China dominates, Europe responds

Four Chinese models — DeepSeek V4, Kimi K2.6, GLM-5 and Qwen 3.5 — hold four of the top five places in the global open-weight ranking this week, and Moonshot is preparing Kimi 3, expected to close the gap with Opus 4.8. The trend, already visible with DeepSeek V4 and Zhipu's open source, is settling in as a structural fact: open weights, free and modifiable, increasingly speak Mandarin.

The European response: Mistral confirmed a new open-weight model in early access this month, the first piece of a new family. Arthur Mensch makes it an argument for "strategic autonomy": running, inspecting and modifying your models without depending on a supplier's terms or on the jurisdiction of a foreign state — an argument reinforced since the American embargo on Fable 5. The company is financing its €4 billion of data centres in France and Sweden, partly with Gulf capital: European autonomy is still being built with money that is not European.

5. Fundraising: a record half-year

Global venture capital reaches $510 billion in the first half of 2026, of which $217 billion for OpenAI and Anthropic, and the week's notable rounds: Helsing $1.8 billion, AIsphere $439 million, Chai Discovery $400 million, Acrab $350 million.
A record half-year, and an unprecedented concentration on two players

Global venture capital reached $510 billion in the first half of 2026, a record above the $440 billion invested over the whole of 2025. OpenAI and Anthropic alone captured $217 billion, or 43% of the half-year's startup funding, and nearly 40 AI startups became unicorns.

The week's most notable round is not a model lab: German defence-tech company Helsing raised $1.8 billion (valuation $18 billion) from JPMorgan, Lightspeed, Iconiq, Goldman and the Canadian pension fund CPPIB. It announces its first American factory in West Virginia to produce the HX-2, an AI-piloted attack drone already deployed in Ukraine and tested by the US Army, at more than 2,000 units a month eventually. AI leaves the browser and enters steel.

The financial radar

6. Infrastructure and energy: the bill and nuclear power

The four cloud giants (Amazon, Google, Microsoft, Meta) plan to commit nearly $250 billion to data centres in 2026, against around a hundred billion in 2025. To sustain demand, Nvidia issued $25 billion of bonds and is multiplying revenue-sharing agreements with its own customers — an arrangement that supports its sales in the short term but complicates the reading of future revenue. Its share price fell by nearly 11% in June, and the financial press openly speaks of a "debt bubble" backed by gigawatts, following on from the Bank for International Settlements warning mentioned in early July.

The constraint becomes physical: energy. This week, Valar Atomics and Nvidia announced a study for a near-waterless data centre powered by a small 30-megawatt modular reactor in Utah. The movement runs deep: Microsoft, Google, Amazon and Meta have committed more than $50 billion to nuclear (13 projects announced, 9.8 GW), with the first nuclear electrons for an AI data centre expected in 2027 with the restart of Three Mile Island. Computing is no longer just a matter of chips: it is a matter of megawatts and cooling.

7. In business: the gap between spend and ROI

Behind the euphoria of the funding rounds, field studies tell a more nuanced story. By the end of 2026, 40% of enterprise applications will embed specialised agents (against less than 5% in 2025, according to Gartner), and 31% of organisations already have at least one agent in production — banking and insurance in the lead (47%), healthcare and the public sector lagging (18%). But the return on investment is slow to come: only 29% of organisations see a significant ROI from generative AI, and 23% for agents. "Power users" gain up to five times in productivity, but 79% of organisations say they face adoption difficulties (up by double digits on a year), and more than half of executives acknowledge that AI is putting their organisation under strain.

What it changes The gap between spend and ROI is not a model problem, it is a deployment problem: scoping use cases, data, integration, change management. That is exactly where value is won — and it is repeatable, unlike the race to the latest model.

8. Jobs: 200 experts and 16 Nobel laureates

On 13 July, more than 200 economists and researchers, including 16 Nobel laureates, signed a letter coordinated by Stanford's Digital Economy Lab. It asks political and industry leaders to "act now" and to build "incentives, safeguards and institutions" so that AI complements humans rather than replacing them. It warns of "massive job displacement" and of a transformation "greater than the industrial revolution, but over a far shorter period", while pointing to possible gains in living standards. Its organiser, Anton Korinek: "waiting for certainty means arriving too late".

The same week, Amazon announced 14,000 job cuts — after 16,000 in January — with Andy Jassy indicating that efficiency gains from AI will reduce headcount. Since the start of 2026, American tech has cut 140,000 jobs, with AI cited in nearly a quarter of the cuts. Jeff Bezos, conversely, predicts a labour shortage. The real subject is neither "AI destroys everything" nor "AI creates everything": it is the lag between the disappearance of jobs and the appearance of new ones, as our timeline of replacement showed.

11. What to take away

Four points for deciding. One: with four frontier models in eight days and falling prices, choosing a model is no longer a strategic decision but a trade-off by use; the strategy lies in what you plug in around it. Two: the lasting advantage is what cannot be copied — proprietary data, distribution, know-how, teams; that is precisely the subject of Apple's complaint. Three: value comes not from the model but from deployment — 40% of apps with agents by the end of 2026, but fewer than a third of companies seeing an ROI; the gap is closed by scoping and integration, not by the race to the latest model. Four: the question of jobs is no longer theoretical — 16 Nobel laureates, the Federal Reserve and Amazon (14,000 jobs) put it on the table in the same week; anticipating the recomposition of your professions becomes a concrete advantage.
