LEO becomes Africa’s first AI chatbot to enable remittances

United Bank for Africa (UBA) has introduced cross-border payments via its AI chatbot, LEO, enabling instant transfers across African nations in local currencies.

However, this marks the first time an AI-powered chatbot has facilitated such transactions on the continent.

The feature relies on the Pan-African Payment and Settlement System, developed by Afreximbank, which allows seamless fund transfers between African countries supported by their central banks. It eliminates the need for hard currencies and aims to reduce fees while supporting financial inclusion.

UBA said the service allows customers to send and receive money across borders within seconds through self-service channels, with zero charges for recipients.

The initiative also supports Africa’s wider economic ambitions under the African Continental Free Trade Area agreement.

The bank operates in 20 African countries and serves over 45 million customers worldwide. CEO Oliver Alawuba described the development as a bold step toward digital innovation and Pan-African integration.

Google expands AI tools in Search with new subscriber perks

Google has begun rolling out new AI features in Search, introducing AI-powered phone calling to help users gather business information instead of contacting places manually.

The service, free for everyone in the US, allows people to search for businesses and have Google’s AI check pricing and availability on their behalf.

Subscribers to Google AI Pro and AI Ultra receive additional exclusive capabilities. These include access to Gemini 2.5 Pro, Google’s most advanced AI model, which supports complex queries such as coding or financial analysis.

Users can enable Gemini 2.5 Pro through the AI Mode tab instead of relying on the default model. Google is also launching Deep Research tools through Deep Search for in-depth investigations related to work, studies, or major life decisions.

Rather than rolling everything out all at once, Google is phasing in the features gradually. AI-powered calling is now available to all Search users in the US, while Gemini 2.5 Pro and Deep Research are becoming available specifically to AI Pro and AI Ultra subscribers.

With these updates, Google aims to position Search as more than a simple information tool by transforming it into an active digital assistant capable of handling everyday tasks and complex research instead of merely providing quick answers.

EU confirms AI Act rollout and releases GPAI Code of Practice

The European Commission has confirmed it will move forward with the EU AI Act exactly as scheduled, instead of granting delays requested by tech giants and businesses.

On 10 July 2025, it published the final General-Purpose AI (GPAI) Code of Practice alongside FAQs to guide organisations aiming to comply with the new law.

Rather than opting for a more flexible timetable, the Commission is standing firm on its regulatory goals. The GPAI Code of Practice, now in its final form, sets out voluntary but strongly recommended steps for companies that want reduced administrative burdens and clearer legal certainty under the AI Act.

The document covers transparency, copyright, and safety standards for advanced AI models, including a model documentation form for providers.

Key dates have already been set. From 2 August 2025, rules covering notifications, governance, and penalties will come into force. By February 2026, official guidelines on classifying high-risk AI systems are expected.

The remaining parts of the legislation will take effect by August 2026, instead of being postponed further.

With the publication of the GPAI Code of Practice, the EU takes another step towards building a unified ethical framework for AI development and deployment across Europe, focusing on transparency, accountability, and respect for fundamental rights.

Broadcom challenges Nvidia with Tomahawk Ultra AI networking chip

Broadcom has introduced a new networking chip designed to boost AI data centre performance, positioning itself against Nvidia in the AI hardware race.

Called Tomahawk Ultra, the chip helps link hundreds of processors within close range, ensuring fast communication vital for large AI models.

Instead of using Nvidia’s proprietary NVLink system, Broadcom’s Tomahawk Ultra operates on an accelerated version of Ethernet and connects up to four times more chips within a server rack.

The chip acts as a traffic controller, enabling what the industry refers to as ‘scale-up’ computing — where AI models tap into combined computing power from tightly grouped chips.

According to Broadcom senior vice president Ram Velaga, it took engineers around three years to design the Tomahawk Ultra, which was originally aimed at high-performance computing but adapted for AI workloads as demand surged.

Taiwan Semiconductor Manufacturing Company (TSMC) is producing the processors using its five-nanometre process, and the chips are already shipping to customers.

Rather than requiring major hardware overhauls, the Tomahawk Ultra offers a scalable, Ethernet-based alternative for AI firms looking to build faster, more flexible data centres.

AI Appreciation Day highlights progress and growing concerns

AI is marking another milestone as experts worldwide reflect on its rapid rise during AI Appreciation Day. From reshaping business workflows to transforming customer experiences, AI’s presence is expanding — but so are concerns over its long-term implications.

Industry leaders point to AI’s growing role across sectors. Patrick Harrington from MetaRouter highlights how control over first-party data is now seen as key instead of just processing large datasets.

Vall Herard of Saifr adds that successful AI implementations depend on combining curated data with human oversight rather than relying purely on machine-driven systems.

Meanwhile, Paula Felstead from HBX Group believes AI could significantly enhance travel experiences, though scaling it across entire organisations remains a challenge.

Voice AI is changing industries that depend on customer interaction, according to Natalie Rutgers from Deepgram. Instead of complex interfaces, voice technology is improving communication in restaurants, hospitals, and banks.

At the same time, experts like Ivan Novikov from Wallarm stress the importance of securing AI systems and the APIs connecting them, as these form the backbone of modern AI services.

While some celebrate AI’s advances, others raise caution. SentinelOne’s Ezzeldin Hussein envisions AI becoming a trusted partner through responsible development rather than unchecked growth.

Naomi Buckwalter from Contrast Security warns that AI-generated code could open security gaps instead of fully replacing human engineering, while Geoff Burke from Object First notes that AI-powered cyberattacks are becoming inevitable for businesses unable to keep pace with evolving threats.
