Top Free Text Generation tools, APIs, and Open Source models

What is AI Text Generation API?

Text Generation, also called Content Generation, enables users to generate natural language text through machine learning models. Typically, this technology employs deep learning techniques, such as recurrent neural networks or transformers, to produce language that resembles human-written text.

With Text Generation, users can create text for a range of applications, including chatbots, virtual assistants, content creation, and language translation. Some text generators offer customization options, including training the model on specific data sets or adjusting the creativity and coherence levels in the generated text.

Top Open Source (Free) AI Text Generation models on the market

For users seeking a cost-effective engine, opting for an open-source model is the recommended choice. Here is the list of best text-to-text generation Open Source Models:

1. Llama 2

Llama 2 comprises pre-trained and finely-tuned generative text models, with a parameter range spanning 7 billion to 70 billion. Llama-2-Chat models demonstrate superior performance compared to open-source chat models across several benchmark tests and remain on par with select closed-source models such as ChatGPT and PaLM.

2. Palm 2

PaLM is an AI model that generates text by working with human language. It has learned how to read and create new, grammatically correct text from an extensive corpus of general training data. Google has introduced PaLM 2 (Pathways Language Model), its latest LLM, boasting exceptional prowess in advanced reasoning, coding, and mathematics. PaLM 2 is offered in diverse sizes, facilitating easy deployment across a wide range of usage scenarios.

‍3. GPT-NeoX-20B

GPT-NeoX-20B is a language model with 20 billion parameters that was trained using the GPT-NeoX library on the Pile. Its architecture closely resembles that of GPT-3 and is nearly identical to GPT-J-6B. The model's training dataset includes a wide range of English-language texts, highlighting its general-purpose functionality.

‍4. GPT-J

GPT-J or GPT-J-6B is a large language model created by EleutherAI in 2021. Its aim is to generate text that sounds like a human being speaking, and it does this by using pre-existing knowledge to continue from a prompt.


BLOOM is a powerful language model that uses extensive text data and advanced computing resources to create coherent sentences. It can accurately replicate human writing in 46 languages and 13 programming languages.

‍6. OPT-175B

OPT-175B is a language tool developed by Meta. It is the most extensive pre-trained language model accessible, with 175 billion parameters.

‍7. GPT-3

GPT-3 was taught using 175 billion parameters, an amount ten times larger than its forerunner, GPT-2. The generated text pieces of GPT-3 are remarkably impressive.

‍8. Falcon 180B LLM

Falcon 180B is a large language model with open-source access. It has 180 billion parameters and is trained on a vast amount of data. It's the best open-source model out there, and one of the top models overall. Falcon-180B is superior to LLaMA-2, StableLM, RedPajama, MPT, and others.

Cons of Using Open Source AI models

‍While open source models offer many advantages, they also come with some potential drawbacks and challenges. Here are some cons of using open source models:

  • Not Entirely Cost Free: Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear expenses related to hosting and server usage, especially when dealing with large or resource-intensive data sets.
  • Lack of Support: Open source models may not come with official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
  • Limited Documentation: Some open source models may have incomplete or poorly maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
  • Security Concerns: Security vulnerabilities can exist in open source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open source models may need to actively monitor for security updates and patches.
  • Scalability and Performance: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle a large number of requests, you may need to invest more time in optimization.
