AI News: EU Designates ChatGPT a VLOSE; Nvidia Invests in MediaTek

AI news on Sept. 1, 2026, is led by a major European regulatory move, a multibillion-dollar technology investment, a new open-weight multimodal model and a California risk-verification bill. The European Commission designated ChatGPT a Very Large Online Search Engine under the Digital Services Act, while Nvidia announced a $3.5 billion investment in MediaTek.

DeepSeek also released open weights for its 305 billion-parameter DeepSeek-V4-Flash-Vision-Exp model, and California lawmakers passed SB 813. Separately, Together AI announced a partnership with Saudi Arabia's Humain for a 250-megawatt data center expected to generate more than $5 billion in annualized revenue in its first year.

Why did the EU designate ChatGPT a VLOSE?

The European Commission announced on Aug. 30 and Aug. 31, 2026, that ChatGPT had been designated a Very Large Online Search Engine, or VLOSE, under the Digital Services Act. The action places the service under the European Union's strictest platform obligations and marks the first time a major AI chatbot has been brought into that category.

Services with about 45 million or more average monthly users in the European Union face heightened duties to assess and mitigate systemic risks. ChatGPT has four months to comply with the added obligations. Potential penalties under the DSA can reach up to 6% of global revenue, according to European Commission announcements and reports in TechCrunch and The New York Times.

The Commission also designated Reddit and Roblox as Very Large Online Platforms. Those services were named alongside ChatGPT, although the legal label applied to ChatGPT is VLOSE. The immediate consequences for ChatGPT are the heightened risk-assessment and mitigation duties, the four-month compliance timetable and exposure to DSA penalties for violations.

Key facts

• EU regulation: ChatGPT was designated a VLOSE under the Digital Services Act.
• Nvidia deal: Nvidia is investing $3.5 billion in MediaTek through convertible bonds.
• DeepSeek release: DeepSeek opened the weights for a 305B-parameter multimodal model under an MIT license.
• California bill: SB 813 passed the Legislature and now heads to the governor.
• Risk-verification target: California would designate independent verification organizations by 2028.
• Data center: Together AI and Humain announced a 250 MW project with projected first-year annualized revenue above $5 billion.

What does Nvidia's $3.5B MediaTek investment cover?

Nvidia is investing $3.5 billion in MediaTek through convertible bonds as part of an expanded partnership announced Aug. 31, 2026. MediaTek will adopt Nvidia's NVLink Fusion technology, allowing customers to integrate custom XPUs into Nvidia rack-scale AI systems. The collaboration also extends to local AI computing and automotive work.

The announcement combines financing with a wider technical collaboration. Nvidia is providing the investment through convertible bonds, while MediaTek is adding NVLink Fusion to support customer-designed XPUs within Nvidia's rack-scale systems. Local AI computing and automotive technology are also named areas of collaboration.

Reports in TechCrunch and PR Newswire described the agreement as an expansion of the companies' partnership. The central confirmed terms are the $3.5 billion commitment, the convertible-bond format, the adoption of NVLink Fusion and the additional work planned around local AI and automotive computing.

DeepSeek open weights and California's SB 813

DeepSeek posted open weights around Aug. 31, 2026, for DeepSeek-V4-Flash-Vision-Exp, a 305B-parameter multimodal model released under an MIT license. According to reports, the model matches the text-only V4-Flash on agent and reasoning tasks while substantially improving results on multimodal agent benchmarks.

The release combines visual capabilities with the agent and reasoning performance reported for DeepSeek's text model. Its open weights and MIT license make the model release a separate development from the commercial infrastructure and regulatory announcements elsewhere in the day's AI news.

In California, the Legislature gave final approval to SB 813 in votes held Aug. 30, 2026. The measure directs the state to designate independent verification organizations for assessing AI model risks by 2028. It now heads to the governor, making executive action the next step for the bill.

The day's other infrastructure announcement came from Together AI and Humain. Their planned 250 MW data center is expected to produce more than $5 billion in annualized revenue during its first year, according to PR Newswire. The revenue expectation is stated on an annualized basis for the data center's first year.

Taken together, the latest artificial intelligence news spans regulation, chips, open models, state oversight and data-center capacity. The EU move creates a compliance clock for ChatGPT; Nvidia is committing capital to MediaTek; DeepSeek is releasing model weights; California is advancing independent risk verification; and Together AI is expanding infrastructure through Humain.
