Mark Zuckerberg’s Meta has this week launched an open-source model of a man-made intelligence mannequin, Llama 2, for public use. The big language mannequin (LLM), which can be utilized to create a ChatGPT-like chatbot, is accessible to startups, established companies and lone operators. However why is Meta doing this and what are the potential dangers concerned?
What does an open-source LLM do?
LLMs underpin AI instruments comparable to chatbots. They’re educated on huge datasets that allow them to imitate human language and even pc coding. If an LLM is made open-source which means its content material is made freely out there for individuals to entry, use and tweak to their very own objective.
Llama 2 is being launched in three variations, together with one that may be constructed into an AI chatbot. The thought is that startups or established companies can entry Llama 2 fashions and tinker with them to create their very own merchandise together with, probably, rivals to ChatGPT or Google’s Bard chatbot – though by Meta’s personal admission Llama 2 is just not fairly on the degree of GPT-4, the LLM behind OpenAI’s ChatGPT.
Nick Clegg, Meta’s president of worldwide affairs, advised BBC Radio 4’s Immediately programme on Wednesday that making LLMs open-source would make them “safer and higher” by inviting exterior scrutiny.
“With the … knowledge of crowds you really make these methods safer and higher and, crucially, you’re taking them out of the … clammy arms of the massive tech firms which at the moment are the one firms which have both the computing energy or the huge reservoirs of information to construct these fashions within the first place.”
There’s additionally a risk that by giving all comers the possibility to launch a rival to ChatGPT, Bard or Microsoft’s Bing chatbot, Meta is probably diluting the aggressive fringe of tech friends comparable to Google.
Meta has admitted in analysis revealed alongside Llama 2 that it “lags behind” GPT-4, however it’s a free competitor to OpenAI nonetheless.
Microsoft is a key monetary backer of OpenAI however is nonetheless supporting the launch of Llama 2. The LLM is accessible for obtain by way of the Microsoft Azure, Amazon Net Companies and Hugging Face platforms.
Are there issues about open-source AI?
Tech professionals together with Elon Musk, a co-founder of OpenAI, have expressed issues about an AI arms race. Open-sourcing makes a strong software on this expertise out there to all.

Dame Wendy Corridor, regius professor of pc science on the College of Southampton, advised the Immediately programme there have been questions over whether or not the tech trade might be trusted to self-regulate LLMs, with the issue looming even bigger for open-source fashions. “It’s a bit like giving individuals a template to construct a nuclear bomb,” she stated.
Dr Andrew Rogoyski, of the Institute for Folks-Centred AI on the College of Surrey, stated open-source fashions have been troublesome to manage. “You’ll be able to’t actually regulate open supply. You’ll be able to regulate the repositories, like Github or Hugging Face, underneath native laws,” he stated.
“You’ll be able to concern licence phrases on the software program that, if abused, might make the abusing firm liable underneath varied types of authorized redress. Nonetheless, being open supply means anybody can get their arms on it, so it doesn’t cease the fallacious individuals grabbing the software program, nor does it cease anybody from misusing it.”
For those who apply to obtain Llama 2 you might be required to comply with an “acceptable use” coverage that features not utilizing the LLMs to encourage or plan “violence or terrorism” or to generate disinformation. Nonetheless, LLMs comparable to that behind ChatGPT are susceptible to producing false data and may be coaxed into overriding security guardrails to supply harmful content material. The Llama 2 launch can be accompanied by a accountable use information for builders.
