Twitter co-founder Jack Dorsey has unveiled Bitchat, a messenger that works without the Internet or servers. It creates a mesh network directly between smartphones via Bluetooth, fully encrypts correspondence and does not require registration or a phone number

Each device in the network becomes a node for transmitting messages, thanks to which they reach the recipient without connecting to the infrastructure. Only text chats are available for now, but in the future, media and Wi-Fi support will appear. You can test it on iOS via TestFlight, an Android version is in development

xAI company has unveiled the new Grok 4 model, which according to various tests provided by this company, is the most powerful AI among existing models.

Elon Musk said based on his experience, this is the first model that can solve complex engineering questions whose answers cannot be found on the internet or books, and it has high intelligence in answering questions on almost any topic. It's only a matter of time before it can make new inventions and discoveries.

Grok 4 has two models: the regular one is a reasoning model with a 256k token context window that can use various tools and has outperformed other powerful models in almost all tests. Additionally, xAI has released a version called Grok 4 Heavy, which uses multiple agents simultaneously to find answers to complex user questions and finally provides the most probable answer by comparing their responses.

Grok 4 has set new records in various tests, including the Humanity’s Last Exam, where it solved 25% of the questions, and when given access to tools like the internet, this rises to 44%, a significant gap from competitors.

Also, in the ARC-AGI-2 test, one of the complex and difficult tests for AI models, Grok 4 managed to solve 16.2% of the questions, twice as much as the next model, Claude Opus 4!

Currently, Grok 4 is only available to users with the $30 SuperGrok subscription, and to access Grok 4 Heavy, the company has introduced the most expensive AI subscription called SuperGrok Heavy at $300 per month!

However, this model is not the best at everything, especially in coding, where users were not very satisfied because it tends to search a lot. The company said it will release a special coding model next month and introduce its own video creation model in about 3 months.
