April 2025	o3 and o4-mini Launch	A new family of reasoning-focused models. The o3 model pushes frontiers in coding, math, and visual perception, while the highly efficient o4-mini is optimized for fast, cost-effective reasoning in high-volume, complex tasks.

🛠️ Early 2025: Functionality and Efficiency

Date	Product/Model Update	Key Features & Significance
Mar 2025	GPT-4o Image Generation	GPT-4o fully replaces the separate DALL-E 3 system for image generation within ChatGPT. This streamlines the process and allows the core multimodal model to handle both prompt creation and image rendering.
Feb 2025	GPT-4.5 (Preview) & Deep Research Mode	GPT-4.5 offered an upgrade in world knowledge and intent understanding. The new Deep Research Mode enabled ChatGPT to perform autonomous, long-form research, generating cited reports across multiple web sources.
Jan 2025	Scheduled Tasks & o3-mini	Introduction of the Scheduled Tasks feature, allowing users to automate recurring prompts, notifications, and reports. o3-mini debuted as a strong small model for STEM and coding.

2024: The Multimodal Revolution

2024 was defined by the launch of GPT-4o, a groundbreaking multimodal model that made voice, vision, and real-time interaction the new standard.

🎤 Mid-to-Late 2024

Date	Product/Model Update	Key Features & Significance
Sept 2024	GPT o1 Model	Unveiled the GPT o1 model, an early step in OpenAI's new "o-series," which was initially released with the capability to "think" before responding for enhanced reasoning.
May 13, 2024	GPT-4o ('Omni') Launch	The most significant update of the year. GPT-4o unified text, audio, and vision into a single, natively multimodal model. It offered GPT-4 level intelligence with dramatically increased speed and was made available to all users (free and paid), democratizing advanced AI.
Jan 2024	GPT Store & ChatGPT Team	The GPT Store launched, providing a marketplace for users to discover and use Custom GPTs created by others. ChatGPT Team was introduced as a collaborative workspace solution for small-to-medium businesses.

2023: Foundation and Commercialization

2023 was the year ChatGPT moved from beta phenomenon to a commercially viable platform, introducing paid tiers, advanced models, and crucial extensions.

🌐 Key Milestones of 2023

October 2023: DALL-E 3 Integration. The text-to-image model was integrated into ChatGPT Plus, allowing users to generate high-quality images directly from conversational prompts.
September 2023: "See, Hear, and Speak" Update. ChatGPT gained multimodal input capabilities, allowing Plus users to upload images for analysis and utilize the Advanced Voice Mode on mobile apps.
March 2023: GPT-4 Release. The successor to GPT-3.5, GPT-4 introduced significantly enhanced reasoning, problem-solving, and a multimodal capability (processing text and image input) that set a new industry benchmark.
February 2023: ChatGPT Plus Launch. The introduction of a $20/month subscription tier provided users with access during peak times, faster response speeds, and priority access to new features like GPT-4.

💡 The Genesis: November 2022

The journey began on November 30, 2022, with the public release of ChatGPT, powered by the GPT-3.5 model. This launch marked the first time a large language model was made easily accessible to the general public, sparking the generative AI revolution.
