LLMs are at a Crossroads, and Lettria Helps Users Find Their Way Forward

The world of AI has seen enormous progress in the development of Large Language Models (LLMs) — neural networks that can understand, generate, and reason about human language. Models like OpenAI's GPT-4 contain billions (perhaps trillions) of parameters and have achieved human-level performance on various Natural Language Processing (NLP) tasks like text generation, machine translation, question answering, and more.

The rise of powerful LLMs has driven significant excitement and investment in artificial intelligence. Their ability to perform complex language understanding and generation seemed almost magical when first unveiled. However, these models also present real concerns, including bias and lack of transparency, high environmental costs, threats to privacy and security, and limitations in generalizing to new domains.

LLMs work by analyzing huge datasets of text to detect patterns in language. As they get larger and more data-hungry, they require enormous computational resources for training and deployment, consuming huge amounts of energy and raising carbon emissions. They also amplify the biases and flaws contained in their training data, and they struggle to apply knowledge in one area to new domains. Despite their impressive capabilities, we are still far from developing LLMs with the broad, flexible intelligence that humans possess.

Challenges with LLMs today

Environmental Impact

Training and running large language models consume a massive amount of energy and contribute significantly to greenhouse gas emissions, which can negatively impact the environment. This issue has gained significant attention in recent years, with some researchers estimating that training a large language model can emit as much CO2 as driving a car for a year. To tackle this problem, Lettria has developed AutoLettria, which enables the training of smaller models that can outperform LLMs on specific tasks such as multi-label classification. These smaller models can run on much smaller servers, reducing the energy consumption and environmental impact.

Bias

Language models are trained on massive datasets, which can contain biased language, leading to biased outputs. This can perpetuate and reinforce systemic inequalities. To handle this challenge, Lettria manages training datasets and provides clear accuracy on performance for each label, along with explainability with patterns. By doing so, Lettria aims to provide unbiased outputs and reduce the potential for systemic inequalities.

Data Privacy and Security

Large language models require vast amounts of data, which can raise concerns about data privacy and security. There have been instances where large language models have been used to extract sensitive information from public datasets. To address this issue, Lettria enables the training and deployment of models on private clouds, allowing users to keep full control and compliance with GDPR.

Lack of Common Sense

Although large language models have advanced significantly in natural language processing, they still lack common sense and reasoning abilities that humans possess, leading to occasional nonsensical or inappropriate responses. To confront this obstacle, Lettria uses a knowledge graph to provide structured information, enabling users to access information and apply their own reasoning. By doing so, Lettria aims to provide more accurate and appropriate responses.

Limitations in Handling Rare or Unseen Situations

Language models trained on existing data may struggle to handle rare or unseen situations. This is because they are trained on a fixed dataset and may not have the ability to generalize to new or unusual scenarios. To deal with this concern, Lettria provides innovative solutions such as zero-shot classification and ontology enrichment, enabling users to handle rare or unseen situations more effectively.

Accessibility

Large language models may require significant computational resources to train and run, making them inaccessible to many researchers and developers who lack access to such resources. To solve this dilemma, Lettria provides a no-code platform that enables business experts to access these technologies and integrate them into their tools for text analysis without requiring technical expertise.

Leveraging LLMs

Despite these challenges and limitations, Lettria recognizes the value of LLMs and aims to leverage their capabilities to provide innovative solutions for various industries.

• For data enrichment for our clients, we can use LLMs to generate training data if the client hasn't labeled enough data. This can be a valuable service we offer to our clients.
• LLMs can be used for zero-shot classification to speed up the annotation process.
• For users who only have raw data and no classification plan, we can import their data into the platform and use LLMs to generate a classification plan.
• LLMs can also be used for ontology enrichment by detecting new attributes, relationships, or classes.
• Lastly, for our data science team, LLMs can be used to label pos-tag, sentiment, and disambiguation datasets automatically with a pretty good accuracy rate.

As you can see, Lettria has a unique position in this field. While we don't have the resources to compete with the big players in building massive LLMs, we have the expertise to leverage these models in a way that is more accessible, ethical, and sustainable. By using smaller models trained on specific tasks, managing training datasets to avoid bias, ensuring data privacy and security, using knowledge graphs to provide structured information, and offering a no-code platform for business experts to access these technologies, we can make LLMs more accessible and useful to a wider audience.

Moreover, Lettria can leverage LLMs to improve our own data science capabilities. By using LLMs for data enrichment, zero-shot classification, topic modeling, ontology management, and text labeling, we can accelerate our time to value and improve our accuracy. We can also offer these capabilities to our clients, enabling them to leverage the power of LLMs in their own data science projects.

Conclusion

It’s clear that Large Language Models have led to remarkable breakthroughs in natural language processing, from machine translation to question answering to text generation. However, they also present real concerns regarding bias, privacy, sustainability, and more that must be addressed to ensure they are developed and applied responsibly.

At Lettria, we believe LLMs can drive new innovations in AI if we are willing to tackle these challenges and limitations head-on. While we do not have the resources to compete with the largest tech companies in building massive models, we have the expertise to leverage LLMs in a way that is ethical, accessible, and impactful. By using smaller, targeted models, carefully managing training data, providing structured knowledge graphs, and offering an easy-to-use no-code platform, we make LLMs more suitable and useful for organizations of all sizes.

We aim to steer LLMs in a direction that is not just beneficial for the largest players in technology but also for companies, developers, and society as a whole. The future of LLMs is both exciting and uncertain; at Lettria, we believe we can harness their possibilities in a way that is responsible and drives real-world progress.
