What are large language models' challenges?
Understanding large language model nuances is crucial in using them in real-world applications. There are three main large language model weaknesses to consider when thinking about how to apply them practically in business:
1. Inconsistent accuracy
Large language models, including OpenAI's GPT-3.5, are powerful tools that can provide accurate responses to complex questions. However, despite their impressive capabilities, there is still a risk of inaccurate or false responses, known as "hallucination."
This phenomenon can have serious implications in critical industries like healthcare and business operations. It is essential to implement safeguards such as human oversight to refine inputs and control outputs to mitigate this risk. Currently, many applications of large language models require human supervision to ensure reliable results.
2. Lack of enterprise context
Large language models have been trained on a vast amount of text data from the internet. Still, they need enterprise-specific context and domain knowledge to provide specific solutions to industry-specific problems. While they can provide general information and context on various topics, they may not have the depth of understanding and experience required to solve complex, industry-specific challenges.
Additionally, language models may not have access to proprietary information or be aware of the specific regulations and policies that govern a particular industry. As a result, they may only sometimes be able to provide accurate or reliable information in the context of a specific enterprise. It is essential to understand these limitations and seek expert advice when dealing with industry-specific issues.
3. Limited controllability
While language models are powerful and accessible to non-experts, they lack controllability. This means their response to a specific input cannot be easily directed or controlled. The layered approach to building LLMs saves time in training complex systems but limits the ability to control the model's responses in a more demanding environment.
To be effective in a business setting, LLMs must be part of a larger AI architecture that offers control and fine-tuning through additional training, evaluation, and alternative machine learning approaches.
4. Stale training data.
Large language models are trained on vast amounts of text data to understand and respond to natural language in a human-like manner. However, their training data is limited to a specific time period and may not reflect the current state of the world. Updating an LLM's knowledge is complex and requires retraining the model, which is extremely expensive.
Instructing the LLM to override certain parts of its knowledge while retaining others is also challenging. Even then, there's no guarantee that the model won't provide outdated information, even if the search engine it's paired with has up-to-date information. This poses a unique challenge in a business setting where data is often private and constantly changing in real-time.
5. Personal data risk
LLMs are trained on vast amounts of text data, including sensitive personal information, which they may have access to while generating responses. This personal information can be leaked through the model's outputs or training data.
Additionally, the training data used to develop LLMs may not always be properly anonymized or secured, which increases the risk of personal data breaches. The use of LLMs in industries handling sensitive personal information, such as healthcare or finance, requires careful consideration and proper security measures to prevent data leakage.
