Generative AI API With GPT-4 And ChatGPT Alternatives

What is Generative AI?

Generative AI is a fancy word designing text generation models. These models take a piece of text as an input and generate the rest of the text for you, in the spirit of your initial input. It is up to you to decide how large you want the generated text to be, and how much context you want to pass to the model in your input..

Let's say you have the following piece of text:

LLaMA 3 is a powerful Natural Language Processing model

Now, let's say you want to generate about 250 words from the above text. Simply send your text to the model and it will generate the rest:

LLaMA 3 is a powerful Natural Language Processing model that does what every model should do: predict your future behavior. It's very effective at detecting patterns in your real-time input, predicting upcoming events and responses that you may not even consider. LLaMA 3's power consists of a set of internal neural processes that are extremely accurate. But at the same time that results are good, they need to be fast. So LLaMA 3 is designed to run on the server. To speed up your results, you may need to use the cloud. Here's why: you may be storing your business data in the cloud. And using the cloud may mean that you can't get your data into the Natural Language Processing process because you have to transfer everything over the cloud.

Foundational generative models usually require some "prompt engineering" in order to understand what you expect from them. You can read more about prompt engineering in our dedicated article about few-shot learning: here.

Once fine-tuned on specific use cases, these generative models can give even more impressive results. Most modern generative models are actually fine-tuned to understand human instructions without requiring any prompt engineering (also known as "instruct" models). You can read more about how to use such instruct models in our dedicated guide: here.

You can achieve any AI use case thanks to generative models, as long as you use and advanced and versatile model: sentiment analysis, grammar and spelling correction, question answering, code generation, machine translation, intent classification, paraphrasing... and much more!

Why Use Generative AI Models?

Generative AI is a great way to automate any sort of task related to text understanding or text writing. Here are a couple of examples.

Marketing Content Generation

Content creation is crucial for SEO today, but it's also a tedious job. Why not leave it to a dedicated AI model, and then focus on something more important?


AI chatbots can significantly enhance customer service efficiency and availability by providing instant, 24/7 responses to inquiries, thereby improving customer satisfaction. They can also automate routine tasks, allowing businesses to allocate human resources to more complex issues and strategic initiatives.

Grammar and Spelling Correction

AI-based spell checking can significantly improve the professionalism and readability of business communications, reducing the likelihood of misunderstandings and enhancing the company's reputation. It also streamlines document preparation and email correspondence, saving time and reducing the burden on employees to catch errors manually.


Summarization can transform lengthy business documents, reports, and communication into concise, easy-to-digest summaries, saving time and ensuring key insights and decisions are quickly accessible. This can improve decision-making, boost productivity, and enhance information retention across all levels of an organization.

NLP Cloud's Generative AI API

NLP Cloud proposes a generative AI API that allows you to perform text generation out of the box with LLaMA 3, ChatDolphin, Mixtral 8x7B, Yi 34B, and more. These models are powerful alternatives to ChatGPT, GPT-3.5, and GPT-4. You can either use our pre-trained models, upload your own generative models, or fine-tune your own generative model perfectly tailored to your use case

For more details, see our documentation about generative models here.

Testing generative AI locally is one thing, but using it reliably in production is another thing. With NLP Cloud you can just do both!

Frequently Asked Questions

What is text generative AI?

Text generative AI refers to artificial intelligence systems designed to automatically create written content, including stories, articles, code, and more, by learning from vast datasets of existing text. It analyzes patterns, contexts, and structures in the data to generate new, coherent, and contextually relevant text on a wide array of topics.

What is the difference between generative AI, deep learning, and machine learning?

Generative AI focuses on creating new data instances (like images, text, or music) that mimic real data, deep learning uses neural networks with multiple layers to learn from large amounts of data, and machine learning is a broader field that encompasses algorithms and statistical models enabling computers to perform tasks without being explicitly programmed for each one, of which deep learning is a subset. In essence, generative AI creates, deep learning provides a sophisticated way to learn from complexity, and machine learning is the overarching principle of teaching computers to learn from data.

How does generative AI differ from other types of artificial intelligence?

Generative AI differs from other types of artificial intelligence by its ability to create new data instances (such as images, text, or sounds) that resemble the training data, unlike traditional AI that focuses on understanding and learning from existing data without generating new data instances. It uses models like Generative Adversarial Networks (GANs) or Variational Autoencoders (VAEs) to produce new outputs that are indistinguishable from real-world data.

What are some practical applications of generative AI across industries?

Generative AI is revolutionizing industries by enabling personalized content creation in marketing, such as generating tailored advertisements or social media content. In the entertainment industry, it aids in the development of realistic computer-generated imagery (CGI) for movies and video games. Additionally, in research and development, generative AI accelerates drug discovery by predicting molecular structures and generating novel compounds, thereby reducing time and costs associated with laboratory experiments.

How are businesses leveraging generative AI to enhance customer experiences?

Businesses are utilizing generative AI to personalize customer interactions and responses in real-time, improving the relevance and efficiency of customer service. Additionally, they are creating immersive and customized content, product recommendations, and experiences that meet specific customer preferences and needs, enhancing overall satisfaction and engagement.

What key technologies enable the operation of generative AI?

Generative AI operates primarily through machine learning algorithms and neural networks, with techniques like Generative Adversarial Networks (GANs) and transformers being especially pivotal for tasks including text generation, image creation, and language translation. High-performance computing resources and massive datasets are also essential for training these models effectively.

How do neural networks contribute to the functionality of generative AI systems?

Neural networks serve as the foundation for generative AI systems by learning patterns, features, and relationships in vast datasets, enabling the generation of new data instances that mimic the original data. This capability is pivotal in applications such as image and speech synthesis, where the AI must understand and replicate complex patterns accurately.

What are the challenges in training generative AI models?

Training generative AI models faces challenges such as requiring vast amounts of data to learn from, and ensuring the accuracy and diversity of the generated outputs without perpetuating biases or producing nonsensical results. Additionally, these models often require significant computational resources, making them expensive and time-consuming to train.

How to evaluate the accuracy of generative AI?

Evaluating a generative AI model typically involves assessing its performance using metrics such as accuracy, precision, recall, and F1 score for predictive tasks, or specialized metrics such as BLEU for natural language generation and Inception Score (IS) or Fréchet Inception Distance (FID) for image generation, alongside qualitative assessment through human evaluation to judge the realism and relevance of generated outputs.
