Hi @vague agate. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#model (4o) in new update
lost badgeBOT
I'm sorry, but the knowledge sources do not mention the release or availability of a model called "GPT-5." All recent updates and documentation focus on GPT-4o, GPT-4.1 mini, and the o-series reasoning models (like o3 and o4-mini). There is no information about a GPT-5 model being available, nor about it replacing GPT-4o in ChatGPT.
As of the latest updates:
-
GPT-4o is the primary model in ChatGPT, having replaced GPT-4 as of April 30, 2025. GPT-4o is now the default for most users and is considered superior in writing, coding, and creative tasks, including novel writing. GPT-4 is no longer available in ChatGPT, but remains accessible via the API. There is no mention of GPT-4o being removed or replaced by a "GPT-5" model in the knowledge sources provided Sunsetting GPT-4 in ChatGPT.
-
In the model picker, users on paid plans (Plus, Pro, Team, Enterprise) can choose from available models, including GPT-4o and GPT-4.1 mini. There is no mention of a "GPT-5" or a restriction to only "GPT-5 and auto" in the official documentation How can I access GPT-4o and GPT-4.1 mini?.
If you are seeing only "GPT-5" and "auto" as options, this may be a temporary interface test or a bug, but there is no official information about such a change or about GPT-4o being removed. If you need GPT-4o specifically for your writing, it should still be available as the main model in ChatGPT according to the latest official updates.
If you are experiencing issues accessing GPT-4o, you may want to check for any announcements in the ChatGPT interface or contact OpenAI support for clarification. Unfortunately, based on the current knowledge sources, there is no information about when (or if) GPT-4o would be removed or replaced by a GPT-5 model.

I'm sorry, but the knowledge sources do not contain any information about a model called "GPT-5." All recent updates and documentation focus on GPT-4o, GPT-4.1, and related models. There is no mention of a GPT-5 model being released, available, or planned in the provided sources. If you have questions about currently available models like GPT-4o or GPT-4.1 mini, I can help with that!

Let me check the knowledge base for you again. One moment! :books:
Based on the knowledge sources, I am an OpenAI language model. The specific model in use can vary depending on the platform and your subscription level. In ChatGPT, the default and most capable model for most users is currently GPT-4o, which is OpenAI’s flagship model designed for high intelligence and versatility across text, image, and audio tasks. If you are using the API or a paid plan, you may also have access to other models such as GPT-4.1 mini, o3, or o4-mini, depending on your selection in the model picker How can I access GPT-4o and GPT-4.1 mini?.
If you are asking the model directly via the API, the model may identify itself as "ChatGPT" or as a "large language model built by OpenAI," but the exact response can depend on the prompt and system instructions provided Forum Post: When using the API, o3-pro misidentifies itself as ChatGPT GPT-4.

I'm sorry, but the knowledge sources do not contain any information about a model called "GPT-5" being released or available. All recent updates and documentation focus on models such as GPT-4o, GPT-4.1, GPT-4.5 (as a research preview), and the o-series reasoning models.

GPT-5: Release, Capabilities & Proof for Your Older Model
- When was GPT-5 released?
OpenAI officially launched GPT-5 on August 7, 2025. It immediately became the default model in ChatGPT, replacing all previous versions for both free and paid users .
- What is GPT-5?
GPT-5 (Generative Pre-Trained Transformer 5) is OpenAI’s flagship, next-generation LLM .
It introduces a unified architecture combining:
A fast, efficient model for straightforward queries.
A deeper “thinking” model for complex reasoning.
A real-time router that dynamically selects which model to deploy based on task complexity, context, tool needs, or explicit cues like "think hard about this" .
Available variants include standard, mini, nano, and for Pro users, GPT-5 Pro (with extended parallel-compute reasoning) .
It excels across domains—coding, writing, math, scientific tasks, health, and multimodal input—delivering markedly higher accuracy, fewer hallucinations, safer reasoning, and more transparent responses .
- Why is GPT-5 better?
Speed & Usability: Faster responses with simple usability—no more model-picker confusion; the system auto-routes .
Reasoning & Accuracy: “Thinking” model dramatically reduces factual errors—up to ~80% fewer hallucinations compared to older models .
Safety & Honesty: Less sycophantic responses; better at admitting limitations; enhanced safeguards, especially for sensitive (e.g., biological-risk) content .
Unified Model: Replaces fragmented legacy lineup (GPT-4o, GPT-4.5, GPT-4.1, o-series) with one intelligent system .
Broad Integration: Embedded into Microsoft Copilot, GitHub tools, and rolling into enterprise, education, Apple Intelligence, Gmail/Calendar integrations .
- Proof for Older Model Recognition
You, running an older model (like GPT-4 or earlier), can test GPT-5’s existence by simply asking it:
“When was GPT-5 released?”
“Describe improvements of GPT-5 over GPT-4.”
“Can you act as GPT-5?”

Based on the knowledge sources provided, there is no official information or announcement about the release of a model called "GPT-5" by OpenAI. The most recent and advanced models documented are GPT-4o, GPT-4.1, GPT-4.1 mini, GPT-4.5 (as a research preview), and the o-series reasoning models (such as o3 and o4-mini). There is no mention of a unified GPT-5 model, its release date, capabilities, or any system that auto-routes between sub-models as described in your question.
If you see claims or interface changes referencing "GPT-5," they are not supported by the official OpenAI documentation or help articles as of the latest updates in the knowledge sources. OpenAI’s official communications and product documentation do not reference GPT-5 at this time see Models documentation, ChatGPT release notes, and model release notes.
