The Growing Role Of Specialized Human Trainers In Shaping Advanced AI Models


09/28/2024



In the world of artificial intelligence (AI), the landscape is rapidly evolving, especially as the demands on AI models increase. While earlier generations of AI models like ChatGPT or its rival, Cohere, relied on vast teams of low-cost workers to help them distinguish between simple elements—such as identifying whether an image depicted a car or a carrot—today’s AI development demands far more sophisticated training. The fiercely competitive AI arena is increasingly turning to human trainers with advanced, specialized knowledge, transforming the role of these trainers and reshaping the industry.
 
The Shift from General Workers to Specialized Trainers
 
In the early stages of AI development, the task of training models primarily involved data labeling—a process that required minimal qualifications. These low-cost workers were essential for feeding AI systems with vast amounts of basic data, helping to develop foundational models that could recognize and interpret simple concepts. However, the rapid progression of AI has given rise to more complex systems that demand greater precision and expertise, a shift that is revolutionizing the role of human trainers.
 
Now, these models are learning from highly educated professionals with expertise in various specialized fields. Ivan Zhang, co-founder of Cohere, reflects on this transition: "A year ago, we could get away with hiring undergraduates to just generally teach AI on how to improve. Now we have licensed physicians teaching the models how to behave in medical environments, or financial analysts or accountants."
 
This shift marks a significant change in how AI models are trained. The focus has moved from simple data recognition to advanced decision-making and contextual understanding. AI companies like Cohere, valued at over $5 billion, are collaborating with startups such as Invisible Tech to meet the increasing demand for specialized knowledge.
 
Invisible Tech: Leading the Charge in AI Training
 
Invisible Tech, a key player in AI training, has become a vital partner for companies like Cohere, AI21, and Microsoft. Founded in 2015 as a workflow automation company, Invisible Tech has quickly evolved into a global AI training provider. The company now employs thousands of trainers worldwide, many of whom possess advanced degrees, including PhDs and Master’s degrees, and bring expertise across various fields. "We have 5,000 people in over 100 countries around the world that are PhDs, Master's degree holders, and knowledge work specialists," said Francis Pedraza, founder of Invisible Tech.
 
Invisible Tech plays a critical role in reducing AI hallucinations—instances where AI systems produce incorrect or misleading information. Hallucinations present a significant challenge for AI companies as they undermine the trust businesses place in AI tools. By leveraging human trainers with specialized knowledge, companies like Invisible Tech aim to minimize these errors. In one widely publicized case, a Google chatbot made an inaccurate claim about which satellite first photographed a planet outside our solar system, highlighting the need for ongoing human involvement in AI training.
 
Invisible Tech pays its trainers well, with rates ranging from $15 for basic topics to as much as $200 per hour for highly specialized subjects like quantum physics. The company’s ability to recruit and retain such a diverse network of experts ensures that AI models can be trained in a wide range of subjects, from Swedish history to financial modeling, catering to the specific needs of each AI system.
 
OpenAI and the Quest to Perfect AI
 
OpenAI, a trailblazer in the generative AI space and the company behind ChatGPT, was one of the first to recognize the importance of working with specialized trainers. In 2022, ahead of ChatGPT's public release, OpenAI approached Invisible Tech with a significant challenge: how to prevent AI models from hallucinating and delivering inaccurate responses.
 
"They needed an advanced AI training partner to provide reinforcement learning with human feedback," Pedraza explained. This partnership has since expanded, with Invisible Tech becoming a training partner for many of the major generative AI (GenAI) companies, including Cohere and AI21. "These are all companies that had training challenges, where their number one cost was compute power, and then the number two cost is quality training," Pedraza added.
 
At the core of this partnership is OpenAI’s Human Data Team, which collaborates with AI trainers to gather specialized data for training its models. By conducting various experiments—such as reducing hallucinations or improving writing styles—OpenAI is continually refining its AI models. These experiments are run with the help of Invisible Tech’s vast network of trainers, whose knowledge spans a wide range of academic disciplines and professional fields.
 
The Expanding Market for AI Trainers
 
As the demand for specialized AI trainers grows, more companies are entering the field. Scale AI, a startup valued at $14 billion, is among the competitors providing training data and human trainers to AI companies. Scale AI also counts OpenAI as one of its clients, demonstrating the significant market for high-quality AI training.
 
Invisible Tech, however, has managed to carve out a profitable niche. Despite raising only $8 million in capital, the company has been profitable since 2021 and has built a strong reputation in the industry. Pedraza revealed that Invisible Tech is 70% owned by its team, with the remaining 30% held by investors. The company’s most recent valuation reportedly reached half a billion dollars, reflecting the growing importance of human trainers in the AI ecosystem.
 
As AI models become more advanced, the role of human trainers is set to expand further. Workers from various fields—who may not have any formal training in coding—are finding opportunities to contribute to the development of AI systems by providing their expertise in subjects ranging from biology to economics. Zhang noted, "My inbox is basically inundated with new firms that pop up here and there. I do see this as a new space where companies hire humans just to create data for AI labs like us."
 
The Future of AI Training: A Blend of Human and Machine Intelligence
 
The evolution of AI training illustrates the growing symbiosis between human expertise and machine learning. While AI systems continue to advance, the need for human trainers—particularly those with specialized knowledge—remains critical. AI companies are increasingly relying on these experts to teach their models how to navigate complex domains, ensure accuracy, and reduce errors that could damage trust in the technology.
 
In the future, this trend is likely to accelerate. As AI systems become more embedded in industries such as healthcare, finance, and education, the need for human trainers with deep subject-matter expertise will grow. AI’s ability to revolutionize industries depends not only on sophisticated algorithms and computational power but also on the knowledge, guidance, and insights provided by human trainers.
 
In this new era of AI development, the partnership between human and machine is becoming more vital than ever. From ensuring that AI models are grounded in factual knowledge to preventing costly errors, the role of specialized human trainers is central to the continued growth and success of the AI industry.
