Recalling GPT models

Listing OpenAI's GPT models: GPT-1 in June 2018, GPT-2 in February 2019, GPT-3 in June 2020, GPT-3.5 mid-2022, and GPT-4 in March 2023.

Charting GPT progress

Tracking the GPT journey: GPT-1 in 2018, GPT-2 in February 2019, GPT-3 in June 2020, January 2022 marks the InstructGPT launch, late 2022 for ChatGPT with GPT-3.5, and March 2023 spotlighting GPT-4.

Below is a chronological overview of the major “GPT” models (and closely related variants) that OpenAI has released or announced publicly, along with approximate release dates. Note that exact launch dates can sometimes differ from publication dates or announcement dates; when available, both are noted.

1. GPT-1

  • Name: GPT (sometimes retroactively called “GPT-1”)
  • Paper Title: “Improving Language Understanding by Generative Pre-Training”
  • Release/Publication Date: June 11, 2018
  • Key Points:
    • Introduced the idea of pre-training a language model on large text corpora and then fine-tuning on specific tasks.
    • Laid foundational concepts for subsequent GPT models.

2. GPT-2

  • Name: GPT-2
  • Paper Title: “Language Models are Unsupervised Multitask Learners”
  • Release/Publication Date: February 14, 2019 (initial announcement)
  • Key Points:
    • Notable for its size (up to 1.5 billion parameters at the largest scale) and surprising text-generation quality for the time.
    • Initially partially withheld due to concerns about misuse; full model was eventually released in stages.

3. GPT-3

  • Name: GPT-3
  • Paper Title: “Language Models are Few-Shot Learners”
  • Release/Publication Date: June 11, 2020
  • Key Points:
    • Significantly larger than GPT-2, with up to 175 billion parameters.
    • Showed impressive zero-shot and few-shot learning capabilities.
    • Formed the backbone for many early text-generation applications via OpenAI’s API.

4. InstructGPT (GPT-3 Fine-Tuned for Instructions)

  • Name: InstructGPT
  • Release/Publication Date: January 2022 (OpenAI announcement)
  • Key Points:
    • A family of GPT-3 models fine-tuned using human feedback (Reinforcement Learning from Human Feedback, RLHF) to follow user instructions more accurately.
    • Focused on safer and more aligned outputs compared to vanilla GPT-3.

5. GPT-3.5 (Including ChatGPT)

  • Name: GPT-3.5 (underlying model for early ChatGPT versions)
  • Public Beta Launch of ChatGPT: November 30, 2022
  • Key Points:
    • An improved version of GPT-3, also fine-tuned with human feedback, primarily optimized for conversational use-cases.
    • “ChatGPT” became widely recognized for its ability to engage in dialogue, handle follow-up questions, and perform complex reasoning within a chat format.
    • Variants include “GPT-3.5-turbo,” used in many ChatGPT deployments and via the OpenAI API.

6. GPT-4

  • Name: GPT-4
  • Release/Announcement Date: March 14, 2023
  • Key Points:
    • Introduced as a more capable, more accurate, and safer model than GPT-3.5.
    • Handles a wide range of tasks, from creative writing to analysis, and shows improved reasoning abilities.
    • Accepts image inputs (for certain OpenAI partners) and demonstrates multimodal capabilities in limited form.

Notes on Future or Rumored Models

  • There is no official GPT-5 as of this writing; any mention is speculative.
  • OpenAI continually refines and updates GPT-4 and GPT-3.5-based models (for example, “GPT-3.5-turbo” updates).

Summary:

  1. GPT-1 — June 2018
  2. GPT-2 — February 2019
  3. GPT-3 — June 2020
  4. InstructGPT — January 2022
  5. GPT-3.5 / ChatGPT — November 2022 (public beta)
  6. GPT-4 — March 2023

These core releases mark the major milestones in OpenAI’s sequence of “GPT” models.
