Top Large Language Model Software: Comparison
When evaluating large language models for your business, it’s important to learn about each tool’s developer, parameters, accessibility, and starting price.
A note on parameters: Though greater parameter size does typically signal higher accuracy of an LLM, remember that you can fine-tune most of these AI tools on your own company-, task-, and industry-specific data. Also, some AI companies offer several LLM models, differing in size, with the lower-parameter versions on the lower end of the pricing scale.

GPT-4: Best for Creating Marketing Content
OpenAI’s GPT-4, accessed typically through the free AI tool ChatGPT, is an advanced natural language processing model. Compared to other LLMs, its combination of large-scale pretraining, contextual understanding, fine-tuning capabilities, and advanced architecture makes GPT particularly adept at writing detailed, sophisticated responses to your prompts, making it a great assistant to any marketer.
By training GPT on your brand’s tone and style, you can have it generate text that fits your specific style and can be easily assimilated into email campaigns, ad copy, social media posts, presentations, and other external and internal content for your business. And with its new image reader, you can even upload an ad image and ask it to write a clever caption.

Key Features of Large Language Model Software
Large language model software typically includes features that help businesses process large amounts of information, and answer complex questions about their market or company data. LLMs also generate intelligent, contextually relevant outputs in various formats, from coding and images to human-like textual responses. Since LLMs are generally meant to be “built-on-top-of,” their APIs and ability to integrate with other applications are also massively important to users.
Conversational AI Chatbot
Most LLMs offer an AI chatbot, which understands and generates human-like responses based on user input and training data. These helpful chatbots continuously improve their performance—aka their ability to follow your directions—by analyzing interactions and your satisfaction with them. Professionals generally use chatbots to quickly write content, conduct research, generate code, and analyze data.
Text Summarization
Text summarization is a powerful feature of LLMs that can save your business a lot of time when it comes to reading and interpreting lengthy documents, such as legal contracts or financial ledgers.
AI-based text summarization works by condensing these swathes of text into concise representations while retaining the key information. Acting like an analyst, this feature can aid in decision-making by providing you with the most relevant details of long reports and studies. It can also help you create content based on the document, such as an abstract for a dense lab report.
Content Generation
Marketers and small business owners will probably find LLMs’ ability to generate content to be its most time-saving feature. Using specific prompts like “Write a witty social media caption to this image,” users can quickly pump out sophisticated and human-like content.
End results include email copy, social media posts, sales pages, product descriptions, and more. Of course, when writing with these tools, you should take care to add your own personality and insight into the copy, acting as its editor. Otherwise, the content might read as robotic and contain errors.
Fine-tunability
Crucial for the applicability of LLMs, fine-tunability is the ability of LLMs to be customized to specific tasks or domain-specific knowledge with relatively small amounts of task-specific data.
For example, pretend a SaaS brand is using a customer chatbot powered by an LLM, and they notice the chatbot is struggling to answer questions about upgrade options for a specific product tier. The company then fine-tunes the LLM using a dataset containing transcripts of buyer interactions related to these specific upgrades, thus improving its performance.
Multimodality
In business, you often need to create more than just text. Multimodality refers to an LLM’s ability to understand and generate responses in other modalities such as code, images, audio, or video.
This opens up opportunities for businesses to create applications that leverage multiple modalities, such as augmented reality (AR) experiences or interactive multimedia content. It also helps businesses engage with customers—imagine a chatbot that can analyze a photo of a broken product and then recommend solutions and steps to fix it in image and text.
APIs & Third-party Integrations
Third-party integrations and application programming interfaces are important features of LLMs because they enable seamless integration of language model capabilities into existing systems and applications, allowing businesses to leverage the power of natural language processing without having to develop their own models from scratch. To illustrate, businesses commonly integrate their LLM with their customer service platform to build smarter AI chatbots.
How to Choose the Best Large Language Model for Your Business
The best large language models typically offer streamlined content generation, text summarization, data analysis, and third-party integrations, while also being highly customizable and accurate. That said, the ideal large language model software for your business is one that aligns with your particular needs, budget, and resources. Before evaluating LLMs, you should also identify the use cases that matter most to you, so you can then find models designed for those applications. Do you value affordability the most? Do you need a robust feature list and have the budget to deploy it? Given the complexity of LLMs – including how rapidly the sector changes – extensive research is always required.
