What is GPT-3.5 Turbo?
OpenAI launched their newest GPT-3.5-Turbo model in March 2023, which has since been incorporated into the well-liked ChatGPT offering.
This model currently represents the pinnacle of language model technology and is 10 times more affordable than its GPT-3 predecessors.
In a shift from older models, which processed unstructured text in a token sequence, GPT-3.5-Turbo adopts a unique method, interpreting a series of messages using a system known as Chat Markup Language, or “ChatML”.
Is GPT-3.5 free?
You can access GPT-3.5 for free by signing up for ChatGPT for free.
Is GPT-3.5 available to the public?
Yes, via OpenAI’s API & via ChatGPT.
What is the difference between GPT-3.5 and GPT-4?
OpenAI launched its advanced language model, GPT-4, on March 14, 2023. It’s an upgrade from its predecessor, GPT-3, bringing more capabilities and improvements. GPT-4 is based on the Generative Pretrained Transformer (GPT) framework, which learns to emulate human communication by processing vast amounts of text.
One of the significant upgrades in GPT-4 is the ability to process images as inputs, in addition to text. This multimodal capability allows GPT-4 to handle more complex tasks, such as image captioning, summarization, or translation. This feature gives GPT-4 a significant edge over GPT-3, which can only accept text inputs.
Although there’s no official announcement about GPT-4’s parameters, it’s suggested that the number is considerably higher than the 175 billion parameters of GPT-3. This increase in parameters allows GPT-4 to generate more coherent, contextual, and suitable text, improving its performance on complex tasks.
GPT-4 also demonstrates an enhanced performance capacity over GPT-3. It can generate intelligent and creative responses to various types of inputs, including research papers, poetry, and legal briefs. Notably, GPT-4 has a significantly lower rate of “hallucinations,” or irrelevant responses, than GPT-3. This improvement in accuracy makes GPT-4 more reliable for real-world applications like natural language processing, chatbots, and automated customer service.
GPT-4 can be accessed in a limited capacity through ChatGPT Plus, where users can interact with the model and provide feedback. The availability of GPT-4 on the free version of ChatGPT is yet to be announced. Developers interested in GPT-4 can also sign up for the commercial GPT-4 API waitlist.
In conclusion, GPT-4 has showcased significant enhancements over GPT-3, making it a clear winner. Its advanced features and improved performance herald a new era in natural language processing, opening up exciting possibilities for the AI community.
What is the difference between GPT-3.5 and GPT-3?
GPT-3 is a deep learning-based language model, released in May 2020, that can generate human-like text, including code, stories, and poems. It boasts 175 billion trainable parameters, making it the largest language model to date.
Language models are statistical tools that predict the next word(s) in a sequence based on a probability distribution. They are trained on large text corpora, such as books, news articles, and web pages, learning the patterns and relationships between words in the language. Language models are utilized in various Natural Language Processing (NLP) tasks like Part of Speech (PoS) Tagging, Machine Translation, Text Classification, Speech Recognition, Information Retrieval, News Article Generation, and Question Answering.
GPT-3.5 was unveiled with the release of ChatGPT, a general-purpose chatbot. This iteration was trained on a combination of text and code before the end of 2021, learning to understand the connections between sentences, words, and parts of words by consuming vast amounts of web content. Instead of releasing GPT-3.5 fully, OpenAI used it to develop several systems optimized for various tasks, all accessible via the OpenAI API.
One system, text-davinci-003, is said to handle complex commands better than models built on GPT-3 and produce higher quality, longer-form writing. OpenAI data scientist Jan Leike stated that text-davinci-003 and GPT-3.5 have higher human preference ratings and fewer severe limitations. Data scientists at Pepper Content have also noted that text-davinci-003 excels in comprehending context behind a request and produces better content as a result, with fewer instances of “hallucination” – creating inconsistent and factually incorrect statements.
GPT-3.5 can be accessed through the OpenAI Playground. The latest model, text-davinci-003, has improved output length, generating 65% longer responses than its predecessor.
While GPT-3.5 appears to be an improvement over GPT-3, it’s unclear exactly how, as OpenAI has not released any official information about GPT-3.5. It is speculated that the improvement could be due to the training approach used for GPT-3.5, which involved human trainers evaluating and ranking the model’s responses, with this feedback then incorporated into the model.
GPT-3.5 still suffers from the limitations of modern language models. It relies solely on statistical patterns in its training data rather than truly understanding the world. It is susceptible to “making stuff up” and its knowledge of the world beyond 2021 is limited. Also, its mechanisms to prevent toxic outputs can be bypassed.

How much does GPT-3.5 turbo cost?
You need to have a ChatGPT Plus account in order to access GPT-3.5 turbo. This costs $20/m.
You can also access it for $0.002 per 1000 tokens via OpenAI’s API
What is GPT-3.5 not good at?
GPT-3.5 is an amazing AI model capable of amazing feats, but it still has some things it fails when compared to humans.
The LLM model has major issues with math (seemingly ironically), hallucinations, reasoning, inferring from a small data set, recent facts, and more…
