Latest AI Models and Their Applications | Generated by AI
Here’s a summary of what we do know (as of mid-September 2025) about GPT-5, Gemini 2.5 Pro, GPT-5 mini, and how they are being used, including in Copilot / premium models:
GPT-5 (OpenAI)
- Released: August 7, 2025. (OpenAI)
- What it is: A unified LLM with improved reasoning, lower hallucination, better performance in coding, math, writing, health, visual perception, etc. It includes a version “GPT-5 pro” for more demanding tasks. (OpenAI)
- Reasoning / thinking: GPT-5 has an internal mechanism (“fast” vs “deeper reasoning”) and users can select “GPT-5 thinking” or give prompts like “think hard about this” to ask for more in-depth reasoning. (OpenAI)
-
Access tiers / limitations:
Gemini 2.5 Pro (Google)
-
Release / availability:
- Gemini 2.5 Pro (experimental) was first announced March 25, 2025. (blog.google)
- The stable (“general availability”) Gemini 2.5 Pro was released June 17, 2025. (Google Cloud)
-
Capabilities: It is Google’s most advanced model in the Gemini 2.5 family. It has things like a large context window (1 million tokens), strong reasoning, coding, multilingual support, etc. (blog.google)
GPT-5 mini
- What / when: GPT-5 mini is a lighter/faster version of GPT-5 that has become available in GitHub Copilot (public preview) in mid-August 2025. (The GitHub Blog)
- Where and how: It’s available in GitHub Copilot Chat (on github.com), in VS Code, on GitHub Mobile (iOS/Android). It will also appear in the model picker for users. (The GitHub Blog)
- Premium requests / cost: It does not consume “premium requests” in GitHub Copilot paid plans. That is, using GPT-5 mini doesn’t use up the “premium request” quota. (The GitHub Blog)
How these are used in Copilot / Premium / Microsoft / GitHub
-
GitHub Copilot:
- All Copilot plans (including Free) now have access to GPT-5 mini. (The GitHub Blog)
- GPT-5 (full version) is available only on paid Copilot plans. (The GitHub Blog)
- Model picker lets users choose between GPT-5, GPT-5 mini, etc., depending on their plan and organization settings. (The GitHub Blog)
-
Microsoft Copilot / Copilot Studio / 365 Copilot:
- Microsoft supports using GPT-5 in its Copilot products. For example, makers using Copilot Studio can select GPT-5, and there is auto-routing between different GPT-5 variants (chat vs reasoning) etc. (Microsoft Developer)
- Premium features generally require paid subscriptions. GPT-5 usage, or higher-capacity models, or those with more reasoning are often restricted to paying users or enterprise tiers. (OpenAI)
If you want, I can also dig into performance comparisons (GPT-5 vs Gemini 2.5 Pro etc.), or future/rumored features. Do you want that?
