OpenAI GPT-5.5 Instant: Fewer Hallucinations, More Speed
OpenAI on Tuesday, May 5, 2026, officially launched GPT-5.5 Instant as the new default model for ChatGPT. According to the company’s internal tests, it produces 52.5% fewer hallucinated claims than its predecessor GPT-5.3 Instant in areas where errors manifest most — medicine, law, and finance. In particularly difficult conversations that users flagged as factually incorrect, the share of inaccuracies dropped by 37.3%. OpenAI The Verge
The model also performed better in mathematics and multimodal reasoning. In the AIME 2025 test, it achieved a score of 81.2 compared to 65.4 for the previous version; in the MMMU-Pro benchmark, it improved from 69.2 to 76. At the same time, OpenAI promises “tighter and more concise” answers without unnecessary emojis. TechCrunch
Deeper personalization is also new. GPT-5.5 Instant can draw context from previous conversations, uploaded files, and even the user’s Gmail so that answers are more accurate and personal. ChatGPT now shows so-called memory sources — the sources it drew from — and users can correct or delete incorrect information. Personalization is first being made available to Plus and Pro subscribers on the web; it will soon arrive on mobile as well. OpenAI
For Czech users, it is key that the model is available for free in the ChatGPT free tier, albeit with expected ads and possible speed limits. Paid Plus and Pro plans remain unchanged in price, but offer priority access and expanded features. For companies and freelancers in the Czech Republic, this means they have the latest technology immediately available — just log in to ChatGPT in Czech and try it out.
Google Gemini 3.2 Flash: TPU Stack as a Secret Weapon
While OpenAI has already released its model, Google is preparing its rapid strike at the developer conference I/O 2026, which starts on May 19. According to unofficial information, Gemini 3.2 Flash — a lighter but extremely fast variant of the Gemini family — should be unveiled there. The release of the open-source model Gemma 4 is also expected. Build Fast With AI Google Blog
Why is Gemini Flash so important? Google doesn’t have to rely on third-party cloud services — it has its own vertical infrastructure of TPUs (Tensor Processing Units), which allows it to serve AI answers in milliseconds to hundreds of millions of users. And these are precisely Google’s home turf: Search, Maps, YouTube, Docs, Drive, and Gmail each have more than a billion active users. AI: Reset to Zero
For the Czech market, Google has a huge advantage in deep integration. Czechs use Gmail, Google Drive, and Search daily — there’s no need to install a new app, just wait for Gemini to appear directly in them. Combined with the expected integration with Apple’s Siri, which is rumored for autumn 2026, this could mean a massive expansion of AI assistants into every phone in Europe. Google’s Czech localization is at a high level, so the experience should be smooth even for less tech-savvy users.
Anthropic Orbit: When AI Comes to You
Anthropic, the third player in this league, has bet on a different approach. Instead of waiting for the user to type something, it is preparing the proactive assistant Orbit. It debuted at the Code with Claude conference on May 6, 2026, in San Francisco and is to be available within the Claude Cowork platform. KuCoin News
Orbit automatically generates personalized briefings based on data from Gmail, Slack, GitHub, Google Calendar, Drive, and Figma. The user logs in to Claude in the morning and instead of an empty chat window sees an overview: what meetings you have, how many mentions in Slack are awaiting a reply, which pull requests need approval, and which designs the designer has updated.

This approach changes AI from a passive tool into an active colleague. Anthropic is primarily targeting product managers, developers, and designers — that is, the group that already forms the core of its paid base today. According to estimates, Claude Code reached annual revenue of over $2.5 billion in April 2026, showing how strong a position Anthropic holds among technical professionals. MetaEra
For Czech startups and development teams, Orbit is interesting mainly because it supports tools that are widely used in the Czech tech ecosystem — GitHub for code, Figma for design, Slack for communication. Although official Czech localization of Claude lags behind ChatGPT, technical English is a common working language for most Czech developers.
Race for Milliseconds: What Does It Mean for Europe?
Three different strategies, one goal — keep users on their platform. OpenAI is betting on the fastest spread through free ChatGPT, Google on deep integration into existing services, and Anthropic on proactivity for professionals. But the common denominator is pressure on speed and usefulness.
This raises questions for European regulators and companies alike. The EU is preparing for the next round of AI Act implementation, which demands transparency for so-called high-risk systems. Models that automatically read emails and generate briefings will have to pass stricter checks. At the same time, pressure on personal data protection is increasing — when AI connects Gmail, Slack, and GitHub, it works with sensitive data subject to GDPR.
For ordinary Czech users, however, the message is simple: AI is becoming faster, more accurate, and less obtrusive. You will no longer have to painstakingly formulate queries — soon your assistant itself will tell you what you should ask.
What is the main difference between GPT-5.5 Instant and the previous GPT-5.3 Instant?
GPT-5.5 Instant brings a significant improvement in accuracy — 52.5% fewer hallucinations in sensitive areas such as medicine or law — and better scores in mathematical and multimodal tests. It can also better draw context from previous conversations and Gmail for more personalized answers.
When exactly will Google Gemini 3.2 Flash be released and will it be available in Czech?
The official unveiling is expected on May 19, 2026, at the Google I/O conference. Google has not announced the exact date of global deployment, but historically it makes its models available quickly, including Czech localization in Search and Workspace applications.
Is Anthropic Orbit available to ordinary users, or only to companies?
Orbit will likely first be available to paid Claude Max subscribers and Cowork business licenses. Anthropic usually tests new features at the highest tiers and only expands them more broadly after verification.
