In recent years, OpenAI’s GPT-3 has revolutionized the world of natural language processing, providing remarkable improvements in tasks like text generation, translation, summarization, and much more. However, due to its high cost and restricted access, many researchers, developers, and businesses have been looking for alternative solutions that can offer similar or even better performance at a lower cost. In this article, we will present the top 10 alternatives to GPT-3 that you should consider in 2023.

GPT-3 is undeniably the state-of-the-art in natural language processing, boasting 175 billion parameters, which enables it to generate coherent and fluent text with high accuracy. However, its high computational cost and the need for a large amount of data have made it inaccessible for many developers and researchers. Fortunately, the growing demand for AI applications has also led to the development of several alternative language models, some of which can be more cost-effective, flexible, or specialized than GPT-3. In this article, we will explore the top 10 alternatives to GPT-3 that can help you accomplish your NLP tasks with less cost and effort.

1. GPT-2

The predecessor of GPT-3, GPT-2, is still a viable alternative for many NLP tasks, especially for those that do not require massive training data or fine-tuning. GPT-2 has 1.5 billion parameters, which is still impressive compared to other models. Moreover, GPT-2 has a more flexible API and a higher level of controllability over its output, which can be crucial for applications like chatbots or content generation.

2. T5

T5 is a transformer-based model developed by Google, and it stands for “Text-to-Text Transfer Transformer.” T5 is unique in that it can perform various NLP tasks, including text classification, question answering, summarization, and translation, by inputting a simple text prompt. T5 also has a smaller size than GPT-3, with 11 billion parameters, which makes it more accessible for small or medium-sized businesses.


BERT (Bidirectional Encoder Representations from Transformers) is a language model developed by Google that excels in tasks like sentiment analysis, named entity recognition, and text classification. BERT is trained on a masked language modeling task, which involves predicting a randomly masked word within a sentence, making it particularly adept at contextual understanding. BERT has 340 million parameters, which is much less than GPT-3 but can still achieve impressive results.

4. RoBERTa

RoBERTa (Robustly Optimized BERT Approach) is a variant of BERT that was optimized for more extensive pre-training and improved performance on NLP benchmarks. RoBERTa has 125 million parameters and achieves better results than BERT on several NLP tasks, including GLUE, RACE, and SQuAD. RoBERTa also has a faster inference time than BERT, making it a practical choice for real-time applications.

5. XLNet

XLNet is another transformer-based model that differs from GPT-3 in that it uses a permutation-based training approach rather than a traditional left-to-right or right-to left approach. This allows XLNet to capture more complex dependencies between words and sentences, making it ideal for tasks like language translation and summarization. XLNet has 340 million parameters, the same as BERT, but it has achieved better results than GPT-2 and even GPT-3 in some tasks.


ALBERT (A Lite BERT) is a variation of BERT that uses a parameter-reduction technique to achieve high performance with fewer parameters. ALBERT has 18x fewer parameters than BERT but has achieved comparable or even better results on several NLP tasks. ALBERT is also faster to train and infer than BERT, making it an excellent choice for applications with limited computational resources.


ELECTRA (Efficiently Learning an Encoder that Classifies Token Replacements Accurately) is another language model that aims to reduce the computational cost of pre-training. ELECTRA trains a discriminator network to distinguish between real and generated tokens, which allows it to use much smaller amounts of training data while achieving comparable results to GPT-2 and GPT-3. ELECTRA has 340 million parameters and has shown promising results on several NLP benchmarks.

8. DeBERTa

DeBERTa (Decoding-enhanced BERT with Disentangled Attention) is a language model that improves upon the attention mechanism used in BERT by decoupling the attention weights into two parts: content-based and position-based. This allows DeBERTa to capture long-range dependencies more effectively and achieve better results on several NLP tasks. DeBERTa has 345 million parameters and has shown promising results on benchmarks like GLUE and SuperGLUE.

9. Reformer

Reformer is a transformer-based model that uses a set of reversible layers to reduce the memory requirements of training and inference. Reformer can handle longer sequences than other models with the same memory budget, making it ideal for tasks like language modeling and translation. Reformer has 7.5 million parameters, making it one of the smallest models on this list, but it has achieved impressive results on several NLP benchmarks.

10. Flax

Flax is an open-source framework for building and training language models based on JAX, a machine learning library for accelerated numerical computing. Flax allows for easy experimentation with different model architectures and training algorithms and can be used to train models like GPT-2 and T5 with fewer computational resources. Flax is an excellent choice for researchers or developers who want to build their own language models or fine-tune existing ones.


While GPT-3 remains the top performer in many NLP tasks, there are several viable alternatives that can offer comparable or even better performance at a lower cost. From the more accessible GPT-2 to the specialized Reformer and Flax, there is a language model for every need and budget. Choosing the right model for your application depends on several factors, such as the type of task, the amount of data, and the computational resources available. We hope that this article has provided you with a useful overview of the top 10 alternatives to GPT-3 that you can consider in 2023.
