Employees of OpenAI eye multi-billion dollar stock sale

According to a source familiar with the talks, OpenAI employees are preparing to sell around $6 billion worth of shares to major investors, including SoftBank Group and Thrive Capital.

The deal, still at an early stage, would push the company’s valuation to $500 billion, up from its current $300 billion.

SoftBank, Thrive and Dragoneer Investment Group are already among OpenAI’s backers, and their participation in the secondary share sale would further strengthen ties with the Microsoft-supported AI company.

Reports suggest the size of the sale could still change as discussions continue.

The planned deal follows SoftBank’s leadership role in OpenAI’s $40 billion primary funding round earlier this year. Employee share sales often reflect strong investor demand and highlight the rapid growth of companies in competitive markets.

OpenAI has seen user numbers and revenues soar in 2025, with weekly active ChatGPT users climbing to about 700 million, up from 400 million in February.

The company doubled its revenue in the first seven months of the year, hitting an annualised run rate of $12 billion, and is expected to reach $20 billion by the end of the year.

New Gemini update remembers your preferences, until you tell it not to

Google has begun rolling out a feature that enables its Gemini AI chatbot to automatically remember key personal details and preferences from previous chats, unless users opt out. However, this builds upon earlier functionality where memory could only be activated on request.

The update is enabled by default on Gemini 2.5 Pro in select countries and will be extended to the 2.5 Flash version later. Users can turn off the setting under Personal Context in the app to deactivate it.

Alongside auto-memory, Google is introducing Temporary Chats, a privacy tool for one-off interactions. These conversations aren’t saved to your history, aren’t used to train Gemini, and are deleted after 72 hours.

Google is also renaming ‘Gemini Apps Activity’ to ‘Keep Activity’, a setting that, when enabled, lets Google sample uploads like files and photos to improve services from 2 September, while still offering the option to opt out.

UK estate agents adopt AI tools to offset hiring challenges

UK property agents are increasingly leveraging AI and automation to tackle a growing skills shortage in the sector, according to an analysis by PropTech provider Reapit.

Reapit’s Property Outlook Report 2025 shows that although agencies continue hiring, most face recruitment difficulties: more than half receive fewer than five qualified applicants per vacancy. Growth in payrolled employees is minimal, and the slowest year-on-year rise since May 2021 reflects wider labour market tightness.

In response, agencies are turning to time-saving technologies. A majority report that automation is more cost-effective than expanding headcount, with nearly 80 percent citing increased productivity from these tools.

This shift towards PropTech and AI reflects deeper structural pressures in the UK real estate sector: high employment costs, slower workforce growth, and increasing demands for efficiency are reshaping the role of technology in agency operations.

Candidates urged to balance AI support with integrity

Taylor Wessing has released guidance for early-career applicants on using AI tools such as ChatGPT, Copilot, Claude and Bing Chat during the application process. The firm frames AI as a helpful ally, not a shortcut, and emphasises responsible and authentic use.

AI can assist with refining cover letters, improving structure, and articulating motivations. It can also support interview preparation through mock question practice and help candidates deepen their understanding of legal issues.

However, authenticity is paramount. Taylor Wessing encourages applicants to ensure their work reflects their voice. Using AI to complete online assessments is explicitly discouraged, as these are designed to evaluate natural ability and personal fit.

According to the firm, while AI can bolster readiness for training schemes, over-reliance or misuse may backfire. They advise transparency about any AI assistance and underscore the importance of integrity throughout the process.

OpenAI’s GPT-5 faces backlash for dull tone

OpenAI’s GPT-5 launched last week to immense anticipation, with CEO Sam Altman likening it to the iPhone’s Retina display moment. Marketing promised state-of-the-art performance across multiple domains, but early user reactions suggested a more incremental step than a revolution.

Many expected transformative leaps, yet improvements mainly were in cost, speed, and reliability. GPT-5’s switch system, which automatically routes queries to the most suitable model, was new, but its writing style drew criticism for being robotic and less nuanced.

Social media buzzed with memes mocking its mistakes, from miscounting letters in ‘blueberry’ to inventing US states. OpenAI quickly reinstated GPT-4 for users who missed its warmer tone, underlining a disconnect between expectations and delivery.

Expert reviews mirrored public sentiment. Gary Marcus called GPT-5 ‘overhyped and underwhelming’, while others saw modest benchmark gains. Coding was the standout, with the model topping leaderboards and producing functional, if simple, applications.

OpenAI emphasised GPT-5’s practical utility and reduced hallucinations, aiming for steadiness over spectacle. At the same time, it may not wow casual users, its coding abilities, enterprise appeal, and affordability position it to generate revenue in the fiercely competitive AI market.

Seedbox.AI backs re-training AI models to boost Europe’s competitiveness

Germany’s Seedbox.AI is betting on re-training large language models (LLMs) rather than competing to build them from scratch. Co-founder Kai Kölsch believes this approach could give Europe a strategic edge in AI.

The Stuttgart-based startup adapts models like Google’s Gemini and Meta’s Llama for medical chatbots and real estate assistant applications. Kölsch compares Europe’s role in AI to improving a car already on the road, rather than reinventing the wheel.

A significant challenge, however, is access to specialised chips and computing power. The European Union is building an AI factory in Stuttgart, Germany, which Seedbox hopes will expand its capabilities in multilingual AI training.

Kölsch warns that splitting the planned EU gigafactories too widely will limit their impact. He also calls for delaying the AI Act, arguing that regulatory uncertainty discourages established companies from innovating.

Europe’s AI sector also struggles with limited venture capital compared to the United States. Kölsch notes that while the money exists, it is often channelled into safer investments abroad.

Talent shortages compound the problem. Seedbox is hiring, but top researchers are lured by Big Tech salaries, far above what European firms typically offer. Kölsch says talent inevitably follows capital, making EU funding reform essential.
