Disclaimer I love exploring new technology, and that includes using AI to help with research and editing! My digital &#8220;team&#8221; includes tools like Google Gemini, Notebook LM, Microsoft Copilot, Perplexity.ai, Claude.ai, and others as needed. They help me gather insights and polish content\u2014so you get the best, most up-to-date information possible.<\/p>\n\n\n\n<p>Back in August I wrote about <a href=\"https:\/\/jorgep.com\/blog\/the-launch-of-gpt-5-a-new-leap-in-ai-intelligence\/\">The Launch of GPT-5: A New Leap in AI Intelligence<\/a> and before that <a href=\"https:\/\/jorgep.com\/blog\/openai-slashes-o3-model-prices-by-80-what-it-means\/\">OpenAI Slashes o3 Model Prices by 80%: What It Means<\/a><\/p>\n\n\n\n<p>This time I am writing about how the very confusing naming convention <strong>OpenAI Models<\/strong> is now consolidating into one. <\/p>\n\n\n\n<p>For years, developers and businesses have managed a sprawling ecosystem of OpenAI models, with different versions optimized for specific tasks. Need a quick, cheap response? There&#8217;s a <strong>gpt-3.5-turbo\u00a0<\/strong> \u00a0for that. Working on advanced reasoning? You&#8217;d choose one of the \u00a0gpt-4\u00a0  series. As of August 2025, that era has officially ended. With the launch of the GPT-5 family, OpenAI has initiated a major consolidation, retiring older, specialized models and folding their distinct capabilities into a new, unified architecture.<\/p>\n\n\n\n<p>This is not just an upgrade; it&#8217;s a strategic shift. The new GPT-5 model family is designed to be the &#8220;one ring&#8221; for most AI tasks. Instead of requiring developers to select different models for different use cases, the flagship GPT-5 uses an internal router to dynamically choose the right reasoning effort for each task, from a quick thought to a multi-step plan.<\/p>\n\n\n\n<p>The consolidation of model capabilities into the GPT-5 ecosystem simplifies development, but it also marks a new era for AI application builders. It\u2019s no longer about picking the right model; it&#8217;s about mastering the single model that can do it all.<\/p>\n\n\n\n<p>The new GPT-5 model family at a glance<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><th>Model<\/th><th>Price per 1M Tokens (Input \/ Output)<\/th><th>Description<\/th><th>Strengths<\/th><th>Ideal Use Cases<\/th><\/tr><tr><td><strong>GPT-5<\/strong><\/td><td><strong>$1.25 \/ $10.00<\/strong><\/td><td>The flagship model, a powerful reasoning engine, with a built-in router that balances speed and thoroughness.<\/td><td>Strong multi-step reasoning, high accuracy on benchmarks, lower hallucination rates, and excellent coding and context handling.<\/td><td>Complex data analysis, research summarization, advanced question answering, and technical decision-making.<\/td><\/tr><tr><td><strong>GPT-5 Codex<\/strong><\/td><td><strong>$1.25 \/ $10.00<\/strong><\/td><td>A specialized, highly optimized version of GPT-5 designed for agentic software engineering and complex coding workflows.<\/td><td><strong>Focuses on execution of coding tasks.<\/strong>&nbsp;Adapts reasoning for both quick fixes and multi-hour debugging.

They may vary based on specific agreements.<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is this consolidation important for the future of AI?<\/h3>\n\n\n\n<p>The consolidation of OpenAI&#8217;s models into the GPT-5 family signifies a major shift towards more versatile and efficient AI architectures. Here&#8217;s why this is important:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reduced Complexity<\/strong>: Developers no longer have to worry about managing a fleet of different models for distinct tasks. This simplifies workflow and speeds up development.<\/li>\n\n\n\n<li><strong>Increased Efficiency<\/strong>: By consolidating functionality, OpenAI has reduced the computational resources needed for running diverse AI applications, with up to 40% better computational efficiency reported for some tasks.<\/li>\n\n\n\n<li><strong>A Steeper Learning Curve<\/strong>: The new architecture, with its internal routing mechanism, presents a new paradigm for developers to learn. Understanding how and when GPT-5 applies different levels of reasoning will be key to effective prompt engineering.<\/li>\n\n\n\n<li><strong>Unified Reasoning<\/strong>: The ability to perform high-level reasoning across text, code, and multimodal inputs from a single model opens new possibilities for creating more sophisticated AI applications.<\/li>\n\n\n\n<li><strong>Lower Costs<\/strong>: The move towards a unified platform and the introduction of a discounted cache for input tokens will lead to significant cost reductions for many use cases.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Retirement dates for older models<\/h3>\n\n\n\n<p>With the release of GPT-5, older OpenAI models are being retired. Here are the key dates to be aware of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>GPT-4.5-preview<\/strong>: Retired from the API on\u00a0<strong>July 14, 2025<\/strong>. Replaced by GPT-4.1.<\/li>\n\n\n\n<li><strong>GPT-4o-realtime-preview<\/strong>: Retired from the API no earlier than\u00a0<strong>September 1, 2025<\/strong>.<\/li>\n\n\n\n<li><strong>GPT-4 and GPT-4-32k (0314 and 0613)<\/strong>: Retired from ChatGPT on\u00a0<strong>April 30, 2025<\/strong>, and from the API on\u00a0<strong>June 6, 2025<\/strong>.<\/li>\n\n\n\n<li><strong>GPT-3.5 Turbo (0301 and 0613)<\/strong>: Retired on\u00a0<strong>February 13, 2025<\/strong>.<\/li>\n\n\n\n<li><strong>Older models (including\u00a0<code>text-davinci<\/code>,\u00a0<code>ada<\/code>,\u00a0<code>babbage<\/code>,\u00a0<code>curie<\/code>, and\u00a0<code>davinci<\/code>)<\/strong>: Retired on\u00a0<strong>January 4, 2024<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>The shift to GPT-5 marks a new chapter for OpenAI and the broader AI ecosystem. By consolidating its offerings, the company is simplifying its product line while pushing the boundaries of what a single, unified AI model can achieve. Developers and businesses should take note of these changes and prepare to adopt the new GPT-5 model family to stay competitive in the fast-evolving AI landscape.<\/p>\n\n\n\n<p>References<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/openai.com\/index\/introducing-gpt-5\/\">Introducing GPT-5 <\/a><\/li>\n\n\n\n<li>Introducing gpt-realtime and Realtime API updates\n<ul class=\"wp-block-list\">\n<li>Realtime API docs:\u00a0<a href=\"https:\/\/platform.openai.com\/docs\/guides\/realtime\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/platform.openai.com\/docs\/guides\/realtime<\/a><\/li>\n\n\n\n<li>OpenAI Blog:\u00a0<a href=\"https:\/\/openai.com\/blog\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/openai.com\/blog<\/a><\/li>\n\n\n\n<li>Search:\u00a0<a href=\"https:\/\/www.google.com\/search?q=site%3Aopenai.com%2Fblog+%22Realtime+API%22+OR+%22gpt-realtime%22\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.google.com\/search?q=site%3Aopenai.com%2Fblog+%22Realtime+API%22+OR+%22gpt-realtime%22<\/a><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><a href=\"https:\/\/openai.com\/index\/introducing-upgrades-to-codex\/\">Introducing upgrades to Codex (specialized GPT-5 Codex)<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.creolestudios.com\/gpt-5-vs-gpt-5-thinking-vs-pro\/\">GPT-5 vs GPT-5 Thinking vs Pro: Key Differences (Creole Studios)<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Back in August I wrote about The Launch of GPT-5: A New Leap in AI Intelligence and before that OpenAI Slashes o3 Model Prices by 80%: What It Means This time I am writing about how the very confusing naming convention OpenAI Models is now consolidating into one.
