Shares in Chinese e-commerce giant Alibaba closed 8.4% higher in Asian trading hours on Thursday, as investors cheered news of developments in the company's AI reasoning model.

The QwQ-32B model, released as a competitor to market disruptor DeepSeek's R1, has 32 billion parameters. Alibaba said it can achieve performance comparable to DeepSeek's R1 model that has 671 billion parameters.

The development is the latest in an increasingly hot AI race, with US-based OpenAI gaining an early mover advantage with its ChatGPT.

Newer models, such as DeepSeek's R1 have claimed to use less processing power, throwing into doubt global investment bets on computing chips made by companies like Nvidia, as well as plays for data centres.

Moderna (MRNA)

On Wednesday, a German court ruled that Pfizer (PFE) and BioNTech (BNTX) had violated a Covid vaccine patent held by Moderna (MRNA), sending the pharma giant's stock nearly 16% higher for the session.

The Duesseldorf court said Pfizer and BioNTech would need to provide information related to earnings derived from the use of that patent and that the pair owes Moderna compensation.

Pfizer and BioNTech had argued that they were authorised to use the technology behind the patent via a press release until the World Health Organization declared that there was no longer a global health emergency.

The ruling can still be appealed by a higher court.

Pfizer's stock was relatively unmoved by the news.
