Digital recreation of Portuguese Fort at Chaliyam in final stages
The Chaliyam Fort holds a special place in the history of erstwhile Calicut under the Zamorins. The Portuguese built the fort at the mouth of the Beypore river around 1530, reportedly with the support of local chieftains opposed to the Calicut kingdom. It was constructed at a strategic location to corner the Zamorin, as the structure was just about 10 km from then Calicut city. The Zamorin's attack on the fort in 1571 followed his alliances with Bijapur Sultan Adil Shah and the Nizam Shah of Ahmadnagar for a 'joint enterprise against the Portuguese on the west coast,' writes K.V. Krishna Ayyar in his book Zamorins of Calicut.
Official sources said on Sunday (July 27, 2025) that augmented reality (AR) 3D models and software to digitally recreate the Chaliyam Fort for viewers at the beach were ready. 'An interactive signboard will be installed at the site, allowing visitors to access the experience by scanning it with their mobile phones,' they added.
3D model of the fort
The AR interface will offer three options— a 3D model of the fort, video descriptions in English and Malayalam detailing its history, and an immersive walkthrough that lets users open the fort's doors using augmented reality. The 3D model was developed by a research team from the State Archaeology Department and Government Arts and Science College, Kozhikode, after examining historical records.
Mr. Ayyar, quoting from Zainuddin Makhdoom's Thuhfathul Mujahideen, wrote that it was agreed 'Adil Shah should attack Goa, Nizam Shah should march on Chaul, and the Zamorin should proceed against Chaliyam.' The Zamorin's army, consisting of Nairs and Muslims, bombarded the fort and blocked Portuguese reinforcements. Supplies sent by the Portuguese allies in Cochin and Cannanore were intercepted. Ayyar wrote that the Portuguese were 'compelled to devour dogs.' Soon after, the Portuguese captain surrendered. The Zamorin then demolished the fort, 'leaving not one stone upon another.'
The Portuguese efforts to control Malabar ended soon after. The Calicut king later rebuilt the Mishkal Mosque at Kuttichira—earlier torched by the Portuguese—using wooden planks taken from the destroyed Chaliyam Fort.

Alibaba unveils new open source AI that creates images with perfect text
Alibaba has released a new open-source image generation model called Qwen-Image that sets itself apart by accurately rendering complex and multilingual text within images, a task where many other AI tools still struggle. Developed by Alibaba's Qwen Team, Qwen-Image is designed to handle everything from handwritten poetry and bilingual posters to e-commerce product labels and classroom diagrams, all while maintaining high-quality, readable text. The model supports both alphabetic scripts, like English, and logographic ones, like Chinese, making it especially useful in multilingual can try out Qwen-Image via the Qwen Chat website by switching to the "Image Generation" mode. The model has also been released under the Apache 2.0 licence, meaning businesses and developers can use, modify, and distribute it — even for commercial purposes — as long as they include the proper training data includes billions of image-text pairs sourced from natural scenes, human portraits, artistic posters, and synthetically generated text data. Interestingly, all the synthetic data used for training was generated in-house by Alibaba, and no AI-generated images from other models were included. This approach helped the model learn to handle rare or complex characters, especially in Chinese. The model was trained in stages, starting with simple captioned images and gradually moving to more complex layouts and dense multilingual text. This curriculum-style training, according to Alibaba, helped Qwen-Image generalise better across various the hood, Qwen-Image combines three main components:-Qwen2.5-VL, a multimodal language model for understanding context-A VAE encoder/decoder, optimised for high-resolution layouts-MMDiT, a diffusion model with a special encoding system for spatial alignmentThese elements work together to produce images that are not only visually appealing but also accurate in terms of text placement and claims that Qwen-Image has been tested against several industry benchmarks for text clarity, layout precision, and prompt-following ability. On the AI Arena public leaderboard, which uses human evaluations to rank AI image models, Qwen-Image reportedly holds third place overall currently and is the highest-ranked open-source model.- EndsMust Watch

Hello AI! Please translate this for me
AI generated image of a foreigner trying to communicate with an Indian local in her native language Not long ago, a video of a young man using a generative AI app to effectively communicate with a local rickshaw driver was doing the rounds of social media. Interestingly, the voice generation app was not only able to hold a conversation with the rickshaw driver but it also struck a bargain for the traveller, bringing the price down from Rs 200 to Rs 120. As generative AI evolves, it's transforming real-world communication too. 'The global market for AI-driven language tools is projected to cross $20 billion by 2030 and India will be a major catalyst in this growth,' shares Dipankar Mukherjee, a Market Analyst and Co-Founder and CEO, Studio Blo. Where AI meets commerce and creativity During a recent trip to south India for product research, Faisal Farooqui, CEO of used AI-powered voice translators to understand and communicate with people in smaller towns and villages. He says, 'AI has been a boon for communication. It's helped us translate feedback more efficiently. The only hiccup? Local syntax, and sarcasm - AI still stumbles there. But what really stood out is how it empowers users who once felt held back by language barriers.' The growing use of language AI platforms is giving a big boost to regional content creators as well. As Rahul Regulapati, Founder & CEO, Galleri5 (Part of Collective Artists Network), explains, 'Earlier, if you weren't fluent in English or Hindi, your content rarely made it to the trending section on platforms like Instagram. But now, thanks to AI tools that can tag and categorise content in many Indian languages, more creators are getting discovered.' As a result, AI is helping bring more diverse voices into the spotlight. A student uses Gen AI to communicate with a Bengaluru local rickshaw driver and also succesfully strikes a bargain. Mostly helpful, but some issues persist Yasir Wani, an Indian product manager working in Riyadh, Saudi Arabia, uses gen AI apps to help him navigate life in a country where the dominant language is alien to him. 'Using AI to bridge the language gap has definitely made life easier. It's made me feel more independent and confident, especially when I need to communicate clearly in Arabic without waiting for a translator or second opinion,' he says. That said, Wani adds that he has noticed some issues. 'It sometimes struggles with nuance—especially with religious, legal, or cultural context,' he says. Dr Sunita Gandhi, a language expert and educationist, points out that at the end of the day, AI is just matching patterns and odds.

ALSO READ: Next up, AI as your friend, philosopher and emotional guide India is a land of cultures, and home to over 22 major languages, according to Ministry of Education. At times it is a challenge one for an Indian to navigate in his own country. As Suman Gandham, Founder and CEO of Posibl AI, notes, 'The Indian language ecosystem is hugely underrepresented in global LLMs. But things are changing. Initiatives like Bhashini by the Indian government, or open-source projects like IndicNLP and AI4Bharat, are building solid datasets for Indic languages. We're also seeing a shift towards adapter-based models and LoRA (Low-Rank Adaptation), which let you fine-tune large models for local contexts without needing to retrain from scratch.' AI generated image As human beings work more with AI tools, there's a tendency to simplify sentences, use more standardised vocabulary, and avoid complex turns of phrase or local idioms. Over time, this could result in a more 'machine-friendly' style of communication -Dr Sunita Gandhi, a language expert and educationist, founder of DEVI Sansthan Apps like Preply, ChatGPT, Google Translate, Microsoft Translate, DeepL, and iTranslate offer features such as real-time text and speech translation, image-to-text conversion, offline functionality, and voice-based interactions—making multilingual communication faster and more convenient than ever. UNESCO estimates that over 40% of the world's 7,000 languages are endangered, with one language disappearing every two weeks—along with the cultural and intellectual heritage it carries. While the threat remains urgent, AI presents a new opportunity for preservation. By training models on rare linguistic data and enabling real-world use in translation, voice synthesis, and content generation, AI could play a critical role in keeping endangered languages alive and relevant.
