Company name: OpenAI
OpenAI GPT-3 GPT-4 GPT-3.5 GPT-4V GPT-5 LLMs Logo

GPT 3.5 refers to the set of models designed to improve on GPT-3 and can understand as well as generate natural language or code. One such model is gpt-3.5-turbo.

GPT-3.5 advances the robustness of natural language applications, tending to prompts with a greater understanding. Its accuracy in text-based tasks and the nuanced comprehension of contexts are significant.

However, like all language models, GPT-3.5 has limitations related to the data quality it was trained on and can still generate false information if given ambiguous inputs.

  • Capabilities:
    • Enhanced conversational capabilities
    • Better context management through prompt size limitations
  • Limitations:
    • Still prone to generating misleading information
    • Increased speed can come at the expense of depth in analysis

Comparison with GPT-3 and GPT-4

GPT-3.5 offers a middle ground between its forerunner, GPT-3, and its successor, GPT-4.

Compared to GPT-3, GPT-3.5 delivers improvements in performance with refined code interpretation and generation abilities, yet it is optimized for interactive use, contrasting with GPT-4’s expanded capabilities in both scale and complexity.

GPT-3.5 often serves as a more cost-effective alternative, striking a balance between speed and sophistication.

Which GPT 3.5 is the best?

As of December 2023, the best GPT-3.5 was gpt-3.5-turbo because of its improved performance, faster processing speed, and generally lower costs.

Is GPT-3.5 updated to 2023

As of December 2023, GPT-3.5 models were not updated to include information up to 2023. The training data of the latest models in this series had a knowledge cut-off of September 2021. The only GPT model that had updated info up to 2023, was the GPT-4 Turbo

Is GPT-3.5 Turbo the same as ChatGPT?

No, GPT-3.5 Turbo is a language model, and ChatGPT is a chat interface (Conversational AI) that leverages GPT-n models to answer user queries. At the moment, ChatGPT leverages GPT-3.5, GPT3-5, and GPT-4 language models.

How can I access GPT-3.5 APIs?

Developers looking to integrate GPT-3.5’s capabilities can access the APIs by registering for access through the OpenAI website. Once registered, they can utilize the API documentation to guide their development process.

Is GPT-3.5 available via API?

Yes, you can access GPT 3.5 via API inside the OpenAI website.
