Types of large language models (LLMs)

Language models can basically be classified into two main categories — statistical models and language models designed on deep neural networks.

Statistical language models

These probabilistic models use statistical techniques to predict the likelihood of a word or sequence of words appearing in a given context. They analyze large corpora of text to learn the patterns of language. 

N-gram models and hidden Markov models (HMMs) are two examples. 

N-gram models analyze sequences of words (n-grams) to predict the probability of the next word appearing. The probability of a word's occurrence is estimated based on the occurrence of the words preceding it within a fixed window of size 'n.' 

For example, consider the sentence, "The cat sat on the mat." In a trigram (3-gram) model, the probability of the word "mat" occurring after the sequence "sat on the" is calculated based on the frequency of this sequence in the training data.

Neural language models

Neural language models utilize neural networks to understand language patterns and word relationships to generate text. They surpass traditional statistical models in detecting complex relationships and dependencies within text. 

Transformer models like GPT use self-attention mechanisms to assess the significance of each word in a sentence, predicting the following word based on contextual dependencies. For example, if we consider the phrase "The cat sat on the," the transformer model might predict "mat" as the next word based on the context provided. 

Among large language models, there are also two primary types — open-domain models and domain-specific models.

• Open-domain models are designed to perform various tasks without needing customization, making them useful for brainstorming, idea generation, and writing assistance. Examples of open-domain models include generative pre-trained transformer (GPT) and bidirectional encoder representations from transformers (BERT). 
• Domain-specific models: Domain-specific models are customized for specific fields, offering precise and accurate outputs. These models are particularly useful in medicine, law, and scientific research, where expertise is crucial. They are trained or fine-tuned on datasets relevant to the domain in question. Examples of domain-specific LLMs include BioBERT (for biomedical texts) and FinBERT (for financial texts).

How much does LLM software cost?

The cost of an LLM depends on multiple factors, like type of license, word usage, token usage, and API call consumptions. The top contenders of LLMs are GPT-4, GPT-Turbo, Llama 3.1, Gemini, and Claude, which offer different payment plans like subscription-based billing for small, mid, and enterprise businesses, tiered billing based on features, tokens, and API integrations and pay-per-use based on actual usage and model capacity and enterprise custom pricing for larger organizations. 

Mostly, LLM software is priced according to the number of tokens consumed and words processed by the model. For example, GPT-4 by OpenAI charges $0.03 per 1000 input tokens and $0.06 for output. Llama 3.1 and Gemini are open-source LLMs that charge between $0.05 to $0.10 per 1000 input tokens and an average of 100 API calls. While the pricing portfolio for every LLM software varies depending on your business type, version, and input data quality, it has become evidently more affordable and budget-friendly with no compromise to processing quality.

Limitations of large language model (LLM) software

While LLMs have boundless benefits, inattentive usage can also lead to grave consequences. Below are the limitations of LLMs that teams should steer clear of:

• Plagiarism: Copying and pasting text from the LLM platform directly on your blog or other marketing media will raise a case of plagiarism. As the data processed by the LLM is mostly internet-scraped, the chances of content duplication and replication become significantly higher. 
• Content bias: LLM platforms can alter or change the cause of events, narratives, incidents, statistics, and numbers, as well as inflate data that can be highly misleading and dangerous. Because of limited training abilities, these platforms have a strong chance of generating factually incorrect content that offends people.
• Hallucination: LLMs even hallucinate and don't correctly register the user's input prompt. Though they might have gotten similar prompts before and know how to answer, they reply in a hallucinated state and don't give you access to data. Writing a follow-up prompt can get LLMs out of this stage and functional again. 
• Cybersecurity and data privacy: LLMs transfer critical, company-sensitive data to public cloud storage systems that make your data more prone to data breaches, vulnerabilities, and zero-day attacks. 
• Skills gap: Deploying and maintaining LLMs requires specialized knowledge, and there may be a skills gap in current teams that needs to be addressed through hiring or training.

How to choose the best large language model (LLM) for your business?

Selecting the right LLM software can impact the success of your projects. To choose the model that suits your needs best, consider the following criteria:

• Use case: Each model has strengths, whether generating content, providing coding assistance, creating chatbots for customer support, or analyzing data. Determine the primary task the LLM will perform and look for models that excel in that specific use case.
• Model size and capacity: Consider the model's size, which often correlates with capacity and processing needs. Larger models can perform various tasks but require more computational resources. Smaller models may be more cost-effective and sufficient for less complex tasks.
