Sam Altman and Sundar Pichai, Mark Zuckerberg says your LLMs are ‘problematic’, like Meta’s; and he is fixing his

Meta CEO Mark Zuckerberg just said which many people have claimed about LLMs — that they are biased. In its Llama 4 release announcement, Meta says that it is specifically addressing “left-leaning” political bias in its AI model, distinguishing this effort from traditional bias concerns around race, gender, and nationality that researchers have long documented. In a blog post the company said, “Our goal is to remove bias from our AI models and to make sure that Llama can understand and articulate both sides of a contentious issue. As part of this work, we’re continuing to make Llama more responsive so that it answers questions, can respond to a variety of different viewpoints without passing judgment, and doesn’t favor some views over others.”Not just this, it claims that ‘Biasness’ or should we say ‘Left Leanings’ is not only problem of Meta LLM, but one that afflicts all leading LLMs. “It’s well-known that all leading LLMs have had issues with bias—specifically, they historically have leaned left when it comes to debated political and social topics. This is due to the types of training data available on the internet,” reads the blog post. Leading LLMs mean, among others, LLMs of Google and OpenAI. “As part of this work, we’re continuing to make Llama more responsive so that it answers questions, can respond to a variety of different viewpoints without passing judgment, and doesn’t favor some views over others,” the post added.Meta’s blog post further goes on to explain how with LLM 4, Meta made improvements on these efforts and that LLM 4 performs significantly better than Llama 3 and is comparable to Grok. It says:* Llama 4 refuses less on debated political and social topics overall (from 7% in Llama 3.3 to below 2%).* Llama 4 is dramatically more balanced with which prompts it refuses to respond to (the proportion of unequal response refusals is now less than 1% on a set of debated topical questions).* Our testing shows that Llama 4 responds with strong political lean at a rate comparable to Grok (and at half of the rate of Llama 3.3) on a contentious set of political or social topics. While we are making progress, we know we have more work to do and will continue to drive this rate further down.While biasness in LLMs is a known fact, what has surprised analysts is that Meta’s post mentions only ‘left leaning’ bias and not ‘right leaning’ as many claim in Elon Musk’s Grok.
