Chat GPT news and informations in 2025
In 2025, ChatGPT shifted from being a “chatbot” to a comprehensive AI platform and operating system. The year was marked by the release of the highly anticipated GPT-5 family and the expansion of reasoning-focused models like the o3 series.
Here is a breakdown of the most important information and news regarding ChatGPT in 2025:
1. The Launch of GPT-5
OpenAI released several versions of GPT-5 throughout the year, moving away from a single model toward specialized tiers:
- GPT-5.2 (Thinking/Pro): Released late in the year, these models focus on “Deep Reasoning.” They are designed for mission-critical tasks in legal, finance, and healthcare, featuring significantly fewer hallucinations and better multi-step planning.
- GPT-5 Instant: A faster, more efficient model that replaced GPT-4o for everyday tasks, offering lightning-fast responses with better conversational nuance.
- Integrated Memory: ChatGPT now features “Long-term Memory” across sessions, meaning it remembers your preferred writing style, database schemas, or project details without you needing to repeat instructions.
2. The “o3” Reasoning Series & Deep Research
Building on the success of the o1 model, OpenAI released the o3 series in early 2025 to compete with rivals like DeepSeek.
- OpenAI Deep Research: A standout feature launched in February 2025. It uses the o3 model to browse the web for up to 30 minutes, synthesizing information into a comprehensive, cited report.
- Reasoning Effort Controls: Users can now toggle between “Low,” “Medium,” and “High” reasoning effort. Higher effort allows the AI to “think” longer to solve complex math or coding problems.
3. ChatGPT as a Platform (In-Chat Apps)
At DevDay 2025, OpenAI introduced a major UI shift: Integrated Apps.
- Direct In-Chat Actions: You can now call specific apps directly within a conversation. For example, typing “Spotify, make a workout playlist” or “Zillow, find houses in Tekirdağ” triggers a mini-app interface inside the chat window.
- Instant Checkout: OpenAI introduced commerce integrations, allowing users to buy products or book flights directly through ChatGPT without leaving the app.
4. Advanced Voice & Multimodal Features
- Sora 2 Integration: OpenAI’s video generation tool, Sora 2, was integrated more deeply, allowing ChatGPT to generate short, high-fidelity video clips from text prompts.
- Interactive Voice: The Advanced Voice Mode became the default, allowing for real-time, emotional conversations. It can now “see” through your camera to discuss your surroundings or help with physical tasks in real-time.
5. Summary of 2025 Key Releases
| Feature/Model | Release Period | Key Impact |
| o3-mini | Jan 2025 | High-speed technical reasoning for free/paid users. |
| Deep Research | Feb 2025 | Automated professional-grade research reports. |
| GPT-5 / 5.2 | Mid-Late 2025 | Major leap in logic, memory, and reliability. |
| Apps SDK | Oct 2025 | Allowed 3rd parties to build tools inside ChatGPT. |
| Your Year in GPT | Dec 2025 | A “Spotify Wrapped” style summary of your AI usage. |
In 2026, OpenAI has significantly restructured its pricing to accommodate casual users, while also introducing a powerful “Deep Research” mode for professionals.
1. ChatGPT Pricing Tiers (2026)
The biggest news is the global rollout of ChatGPT Go, a mid-range tier designed for those who need more than the free version but don’t want to pay the full price for Plus.
| Tier | Monthly Price | Best For… | Key Features |
| Free | $0 | Casual use | Access to GPT-5.2 (limited), Basic Search. |
| Go | $8 | Power casuals | 10x more messages than Free; uses GPT-5.2 Instant; includes ads. |
| Plus | $20 | Professionals | GPT-5.2 Thinking model; No ads; Sora 2 video access; 25 Deep Research queries. |
| Pro | $200 | AI Power users | GPT-5.2 Pro; 250 Deep Research queries; Max context window (millions of tokens). |
Note on “Go” Tier: While affordable, the Go tier does not include the Sora 2 video generation and will display contextually relevant ads at the bottom of the chat interface.
2. How to Use Deep Research Mode
Deep Research is no longer just a “Google search on steroids”; it is an autonomous agent that can take 5 to 30 minutes to complete a task.
How to Start:
- Select the Tool: Click the “+” (Tools menu) in the chat bar or type
/deepresearchdirectly. - Define Your Sources: A new 2026 feature allows you to specify sites. You can tell it to “Only use academic journals” or “Prioritize technical documentation from GitHub.”
- Review the Research Plan: Before it starts, ChatGPT will present a “Research Plan” (e.g., “I will first look at X, then compare it to Y”). You can edit this plan to save time.
- The Fullscreen Viewer: Once finished, the report opens in a new fullscreen document view with a clickable Table of Contents and a sidebar showing every source it cited.
3. Why Use Deep Research vs. Standard Search?
- Standard Search: Best for “What is the weather in New York?” or “Who won the game last night?” (Instant response).
- Deep Research: Best for “Compare the last three years of solid-state battery patents between Toyota and QuantumScape and write a 10-page report.” (Takes ~15 minutes).
