August 15, 2025 — GPT-5 Updates

We’re making GPT-5’s default personality warmer and more familiar. This is in response to user feedback that the initial version of GPT-5 came across as too reserved and professional. The differences in personality should feel subtle but create a noticeably more approachable ChatGPT experience.Warmth here means small acknowledgements that make interactions feel more personable — for example, “Good question,” “Great start,” or briefly recognizing the user’s circumstances when relevant. This is different from sycophancy, which we define as excessive flattery that can feel insincere. You can find more about our learnings on reducing sycophancyhere.This update does not show an increase in sycophancy compared to the previous personality of GPT-5, measured by the same internal evals we ran and detailed in oursystem card. Teaching models to be warm without being sycophantic is an ongoing research challenge, and we will continue iterating to get this right. More updates are coming soon.

June 13, 2025 — Improvements to the ChatGPT search response quality

We’ve upgraded ChatGPT search for all users to provide even more comprehensive, up-to-date responses. In testing, we found users preferred these search improvements over our previous search experience.
Improved quality
Smarter responses that are more intelligent, are better at understanding what you’re asking, and provide more comprehensive answers.Handles longer conversational contexts, allowing better intelligence in longer conversations.
Improved search capability and instruction following
More robust ability to follow instructions, especially in longer conversations, significantly reducing repetitive responses.Capability to run multiple searches automatically for complex or difficult questions.Search the web using an image you’ve uploaded.
Known limitations
Users may notice longer responses with this new search experience.In some cases, a “chain of thought” reasoning will show up unexpectedly for simple queries. A fix for this is rolling out to users shortly.ChatGPT may still make occasional mistakes - please double check responses.

ChatGPT 10 Jun 2025 chatgpt

June 10, 2025 — Today, we're launching OpenAI o3-pro—available now for Pro users in ChatGPT and in our API.

Like o1-pro, o3-pro is a version of our most intelligent model, o3, designed to think longer and provide the most reliable responses. Since the launch of o1-pro, users have favored this model for domains such as math, science, and coding—areas where o3-pro continues to excel, as shown in academic evaluations. Like o3, o3-pro has access to tools that make ChatGPT useful—it can search the web, analyze files, reason about visual inputs, use Python, personalize responses using memory, and more. Because o3-pro has access to tools, responses typically take longer than o1-pro to complete. We recommend using it for challenging questions where reliability matters more than speed, and waiting a few minutes is worth the tradeoff.
In expert evaluations, reviewers consistently prefer o3-pro over o3 in every tested category and especially in key domains like science, education, programming, business, and writing help. Reviewers also rated o3-pro consistently higher for clarity, comprehensiveness, instruction-following, and accuracy.
Academic evaluations show that o3-pro consistently outperforms both o1-pro and o3.
To assess the key strength of o3-pro, we once again use our rigorous "4/4 reliability" evaluation, where a model is considered successful only if it correctly answers a question in all four attempts, not just one:
o3-pro is available in the model picker for Pro and Team users starting today, replacing o1-pro. Enterprise and Edu users will get access the week after.
As o3-pro uses the same underlying model as o3, full safety details can be found in theo3 system card.
Limitations
At the moment, temporary chats are disabled for o3-pro as we resolve a technical issue.
Image generation is not supported within o3-pro—please use GPT-4o, OpenAI o3, or OpenAI o4-mini to generate images.
Canvas is also currently not supported within o3-pro.

June 7, 2025 — Updates to Advanced Voice Mode for paid users

We're upgrading Advanced Voice in ChatGPT for paid users with significant enhancements in intonation and naturalness, making interactions feel more fluid and human-like. When we first launched Advanced Voice, it represented a leap forward in AI speech—now, it speaks even more naturally, with subtler intonation, realistic cadence (including pauses and emphases), and more on-point expressiveness for certain emotions including empathy, sarcasm, and more.Voice also now offers intuitive and effective language translation. Just ask Voice to translate between languages, and it will continue translating throughout your conversation until you tell it to stop or switch. It’s ready to translate whenever you need it—whether you're asking for directions in Italy or chatting with a colleague from the Tokyo office. For example, at a restaurant in Brazil, Voice can translate your English sentences into Portuguese, and the waiter’s Portuguese responses back into English—making conversations effortless, no matter where you are or who you're speaking with.This upgrade to Advanced Voice is available for all paid users across markets and platforms—just tap the Voice icon in the message composer to get started.This update is in addition to improvements we made earlier this year to ensure fewer interruptions and improved accents.
Known Limitations
In testing, we've observed that this update may occasionally cause minor decreases in audio quality, including unexpected variations in tone and pitch. These issues are more noticeable with certain voice options. We expect to improve audio consistency over time.Additionally, rare hallucinations in Voice Mode persist with this update, resulting in unintended sounds resembling ads, gibberish, or background music. We are actively investigating these issues and working toward a solution.

Tracking what they’re building

Observed site activity — new pages appearing on each platform’s website, updated daily.

What is the LLM Changelog?

The LLM Changelog is a live, automated tracker that monitors release notes and documentation updates across the largest AI platforms — including OpenAI's ChatGPT, Google's Gemini, Perplexity AI, Microsoft Copilot and Google Search. Changes are crawled daily and presented in a single, searchable feed.

Why AI Platform Changes Matter for Brands

When AI models update their training data, adjust ranking signals or change how they cite sources, the brands and products they recommend can shift overnight. An API change to Gemini or a new feature in ChatGPT can alter which businesses get mentioned in millions of AI-generated responses.

Platforms We Track

We currently monitor ChatGPT release notes, OpenAI developer and model changelogs, Gemini API and app updates, Perplexity product and API changes, Microsoft 365 Copilot release notes, and Google Search Central documentation updates. New sources are added as the AI landscape evolves.
