Researchers of artificial intelligence (AI) from Stanford managed to develop their ChatGPT chatbot demo Alpaca in less than two months but terminated it citing “hosting costs and the inadequacies of content filters” in the large language model’s (LLM) behaviour.

The termination announcement was made less than a week after it was released, as per Stanford Daily.

The source code of the ChatGPT model of Stanford — developed for less than $600 — is available publicly.

According to researchers, their chatbot model had a similar performance to OpenAI’s ChatGPT 3.5.

Scientists in their announcement said that their chatbot Alpaca is only for academic research and not for general use in the near future.

Alpaca researcher Tatsunori Hashimoto of the Computer Science Department said: “We think the interesting work is in developing methods on top of Alpaca [since the dataset itself is just a combination of known ideas], so we don’t have current plans along the lines of making more datasets of the same kind or scaling up the model,”

Alpaca was developed on Meta AI’s LLaMA 7B model and generated training data with the method known as self-instruct.

Adjunct professor Douwe Kiela noted that “As soon as the LLaMA model came out, the race was on.”

Kiela who also worked as an AI researcher at Facebook said that “Somebody was going to be the first to instruction-finetune the model, and so the Alpaca team was the first … and that’s one of the reasons it kind of went viral.”

“It’s a really, really cool, simple idea, and they executed really well.”

Hashimoto said that the “LLaMA base model is trained to predict the next word on internet data and that instruction-finetuning modifies the model to prefer completions that follow instructions over those that do not.”

The source code of Alpaca is available on GitHub — a source code sharing platform — and was viewed 17,500 times. More than 2,400 people have used the code for their own model.

“I think much of the observed performance of Alpaca comes from LLaMA, and so the base language model is still a key bottleneck,” Hashimoto stated.

As the use of artificial intelligence systems has been increasing with every passing day, scientists and experts have been debating over the publishing of the source code, data used by companies and their methods to train their AI models and the overall transparency of the technology.

He was of the view that “I think one of the safest ways to move forward with this technology is to make sure that it is not in too few hands.”

“We need to have places like Stanford, doing cutting-edge research on these large language models in the open. So I thought it was very encouraging that Stanford is still actually one of the big players in this large language model space,” Kiela noted.

Bitcoin makes its first breach of $94,000.

As news broke that Donald Trump’s social media company was in negotiations to acquire cryptocurrency trading platform Bakkt (BKKT.N), Bitcoin surged to a record high above $94,000, adding to optimism that the next Trump administration would be cryptocurrency-friendly.

This year, Bitcoin, the largest and most well-known cryptocurrency in the world, has more than doubled in value. Just before the close of the previous session, it reached a record high of $94,078 before closing at $92,104 in Asian hours on Wednesday.

According to the Financial Times, which cited two persons with knowledge, NYSE-owner Intercontinental Exchange (ICE.N) is supporting Trump Media and Technology Group (DJT.O), opens new tab, which runs Truth Social, in its pursuit of an all-stock purchase of Bakkt.

In addition to traders taking advantage of the first day of options trading on the Nasdaq over BlackRock’s Bitcoin ETF (IBIT.O), Tony Sycamore, market analyst at IG, stated that the Trump deal chatter had helped push bitcoin to a record high.

As traders hoped that President-elect Trump’s pledged support for digital assets would result in a less stringent regulatory framework and give bitcoin a boost after a sluggish few months, cryptocurrencies have surged since the U.S. election on November 5.

According to data and analytics aggregator CoinGecko, the global cryptocurrency market is now worth over $3 trillion, a new high, due to the growing excitement.

Australian online broker Pepperstone’s head of research, Chris Weston, stated that there is genuine underlying purchasing pressure on bitcoin and that “another kick higher should bring in a fresh chase from those who like to buy what’s strong.”

The PTA discloses how many VPNs are registered in Pakistan.

Speaking at the Senate Standing Committee on IT meeting in Islamabad, which was presided over by Palwasha Khan, was the PTA chief.

The continuous regulation of Virtual Private Networks (VPNs) in Pakistan was the main topic of discussion. The committee called for the next meeting and voiced concerns about the Minister of State for IT’s absence for the third consecutive session.

“We have spent the last two years developing VPN legislation. Uninterrupted internet connection is guaranteed by registered VPNs without sacrificing privacy, according to the PTA chairman.

During the session, Senator Muhammad Humayun criticized the measures, saying, “Shutting down platforms like X (formerly Twitter) is jeopardizing the entire IT industry and impacting the livelihoods of over 2.5 million individuals in Pakistan.”

He opposed laws that would hurt independent contractors and small companies.

Although the PTA promised that registered VPNs would not experience internet outages, committee members wanted to know the exact legal foundation for these regulations. Senator Kamran Murtaza asked for documents that detailed the requirements for registration.

“If VPN services are abruptly halted, there will be a major backlash,” Senator Afnan Ullah said. While pointing out that Pakistan’s IT exports had increased by 20% in the previous year, he emphasised that the sector was still lagging behind India.

Concerns over the viability of the existing VPN whitelist method were voiced by the committee. While IT officials admitted that more than 1 million freelancers in Pakistan rely significantly on VPNs for their business, Senator Humayun pointed out that the laws should be more beneficial than harmful.

The National Computer Emergency Response Team (CERT) has released a security advisory concerning the increasing utilization of artificial intelligence (AI) chatbots, emphasizing potential hazards related to the exposing of private data.

The recommendation recognizes that AI chatbots, like ChatGPT, have gained significant popularity for personal and professional duties owing to their capacity to improve productivity and engagement. Nonetheless, the CERT cautions that these AI systems frequently retain sensitive information, so posing a danger of data breaches.

Engagements with AI chatbots may encompass sensitive information, such as corporate strategy, personal dialogues, or confidential correspondence, which could be compromised if inadequately safeguarded. The warning emphasizes the necessity for a comprehensive cybersecurity framework to alleviate concerns associated with AI chatbot utilization.

Users are advised against inputting critical information into AI chatbots and are encouraged to deactivate any chat-saving functionalities to mitigate the danger of unwanted data access. The CERT additionally advises performing routine system security checks and employing monitoring tools to identify any anomalous behavior from AI chatbots.

Organizations are urged to adopt rigorous security protocols to safeguard against possible data breaches resulting from AI-driven interactions.
