# Best Large Language Models (LLMs) Software

  *By [Bijou Barry](https://research.g2.com/insights/author/bijou-barry)*

   Large language models (LLMs) are advanced AI systems engineered to comprehend, interpret, and generate human-like text, leveraging transformer architectures and massive training datasets to perform tasks including translation, summarization, question answering, sentiment analysis, and content generation, and integrating into applications to automate language-heavy workflows.

### Core Capabilities of LLM Software

To qualify for inclusion in the Large Language Models (LLM) category, a product must:

- Offer a large-scale language model capable of comprehending and generating human-like text, made available for commercial use
- Provide a language model with a parameter size greater than 10 billion
- Provide robust and secure APIs or integration tools enabling businesses to incorporate the model into existing systems
- Have comprehensive mechanisms in place for data privacy, ethical use, and content moderation
- Deliver reliable customer support, extensive documentation, and consistent updates to ensure ongoing relevance

### Common Use Cases for LLM Software

Developers and enterprises use LLMs as a foundational layer to power a wide range of language-driven applications. Common use cases include:

- Powering conversational interfaces, customer support chatbots, and internal knowledge assistants
- Automating content generation, summarization, and translation at scale across business workflows
- Supporting reasoning-driven insights through advanced LLMs with multi-step logical reasoning capabilities

### How LLM Software Differs from Other Tools

LLMs are designed to be versatile and foundational, distinct from the [AI chatbots](https://www.g2.com/categories/ai-chatbots) category, which focuses on standalone platforms for end-user interaction with LLMs, and the [synthetic media](https://www.g2.com/categories/synthetic-media) category, which covers tools for creating AI-generated media. LLMs can be open-source (freely downloadable and modifiable) or closed-source/proprietary (available only via API). Some LLMs include reasoning capabilities for complex problem-solving, while base models focus on next-token prediction for faster, pattern-based responses.

### Insights from G2 on LLM Software

Based on category trends on G2, output quality and API integration flexibility stand out as the most valued capabilities. Accelerated language feature development and broad applicability across use cases stand out as primary drivers of adoption.

## Buyer Guide

### What You Should Know About Large Language Models (LLMs)

Large language models (LLMs) are machine learning models developed to understand and interact with human language at scale. These advanced [artificial intelligence (AI)](https://www.g2.com/articles/what-is-artificial-intelligence) systems are trained on vast amounts of text data to predict plausible language and maintain a natural flow.

### **What are large language models (LLMs)?**

LLMs are a type of [Generative AI](https://www.g2.com/categories/generative-ai)models that use [deep learning](https://www.g2.com/articles/deep-learning) and large text-based data sets to perform various [natural language processing (NLP)](https://www.g2.com/glossary/natural-language-processing-definition) tasks.

These models analyze probability distributions over word sequences, allowing them to predict the most likely next word within a sentence based on context. This capability fuels content creation, document summarization, language translation, and code generation. 

The term "large” refers to the number of parameters in the model, which are essentially the weights it learns during training to predict the next token in a sequence, or it can also refer to the size of the dataset used for training.

### **How do large language models (LLMs) work?**

LLMs are designed to understand the probability of a single token or sequence of tokens in a longer sequence. The model learns these probabilities by repeatedly analyzing examples of text and understanding which words and tokens are more likely to follow others. 

The training process for LLMs is multi-stage and involves [unsupervised learning](https://learn.g2.com/unsupervised-learning), self-supervised learning, and deep learning. A key component of this process is the self-attention mechanism, which helps LLMs understand the relationship between words and concepts. It assigns a weight or score to each token within the data to establish its relationship with other tokens.

Here’s a brief rundown of the whole process:

- A large amount of language data is fed to the LLM from various sources such as books, websites, code, and other forms of written text.
- The model comprehends the building blocks of language and identifies how words are used and sequenced through pattern recognition with unsupervised learning.
- Self-supervised learning is used to understand context and word relationships by predicting the following words.
- Deep learning with [neural networks](https://www.g2.com/glossary/artificial-neural-network-definition) learns language's overall meaning and structure, going beyond just predicting the next word.
- The self-attention mechanism refines the understanding by assigning a score to each token to establish its influence on other tokens. During training, scores (or weights) are learned, indicating the relevance of all tokens in the sequence to the current token being processed and giving more attention to relevant tokens during prediction.

### What are the common features of large language models (LLMs)?

LLMs are equipped with features such as text generation, summarization, and [sentiment analysis](https://www.g2.com/glossary/sentiment-analysis-definition) to complete a wide range of NLP tasks.

### 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](https://www.g2.com/articles/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)](https://www.g2.com/glossary/gpt-3-definition)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).

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?
