CAIN 2026 is the fifth edition of the International Conference on AI Engineering – Software Engineering for AI, and it will be held 12–18 April 2026 in Rio de Janeiro, Brazil. Co-located with the International Conference on Software Engineering (ICSE 2026), CAIN brings together researchers and practitioners who build, deploy and maintain AI-enabled systems.
The conference addresses the unique challenges of engineering software for AI and machine-learning systems, recognising that traditional software engineering practices must evolve to account for data-centric development, continuous learning and probabilistic behaviour. The 2026 program explores topics ranging from requirements engineering and data management to architecture, continuous integration, quality attributes, collaboration and infrastructure for AI systems .
Attendees will encounter keynotes from leaders in academia and industry, paper presentations detailing new research, practical industry talks, and a doctoral symposium designed to mentor early‑career researchers. CAIN also features panel discussions and open forums that examine ethical and regulatory considerations, reproducibility, fairness and transparency in AI engineering.
Participants are encouraged to share case studies and lessons learned from deploying AI in domains such as healthcare, finance, robotics, and social media. With its location in Rio de Janeiro’s beachfront Barra da Tijuca neighbourhood, CAIN 2026 offers a vibrant setting for networking and collaboration.
The conference venue, the Windsor Barra Hotel, provides extensive convention facilities, making it ideal for multi-track sessions and community gatherings. Beyond the formal program, CAIN fosters cross-pollination between software engineering and AI by organising informal meetups and mentoring sessions.
The goal is to equip engineers with best practices for building responsible, maintainable and scalable AI systems, while deepening collaboration between academia and industry. As AI continues to permeate critical infrastructure and consumer products, CAIN 2026 serves as a platform to tackle the evolving technical, ethical and organisational issues in AI engineering, ensuring that future systems are reliable, transparent and aligned with human values.

City Vibes
Rio de Janeiro, Brazil
The city’s vibe is a perfect blend of natural beauty and urban chaos. Towering mountains and lush rainforests surround the urban sprawl, creating a dramatic backdrop to daily life. Locals, or Cariocas, exude warmth and friendliness, welcoming visitors with open arms and infectious smiles. The atmosphere is a unique mix of laid-back beach culture and energetic nightlife, with bars, clubs, and street vendors keeping the city alive until dawn.
No visit to Rio is complete without experiencing its must-see views. Take a cable car up to Sugarloaf for sweeping panoramas of the city and bay, or hike to the Christ the Redeemer statue atop Corcovado Mountain for a truly awe-inspiring sight. At sunset, the city transforms as the sky turns fiery orange, casting a magical glow over the skyline.
Whether you’re wandering through vibrant markets, dancing to live music in a samba club, or simply soaking up the sun on the beach, Rio de Janeiro offers an atmosphere that’s lively, welcoming, and undeniably unforgettable. It’s a city that invites you to embrace its passion for life and celebrate every moment.
District Vibes
Barra da Tijuca, Rio de Janeiro, Brazil
As you stroll along its expansive, pristine beaches, you'll feel the soft sand beneath your feet and hear the gentle crash of Atlantic waves—perfect for surfing, kiteboarding, or simply soaking up the sun. The coastline stretches for miles, offering numerous spots to settle in with a cold coconut or a refreshing caipirinha while watching the sunset. Barra’s beaches tend to be less crowded than Copacabana or Ipanema, making it a peaceful oasis for locals and visitors alike.
Beyond the sands, the district is a hub of modern luxury and outdoor activity. The towering high-rises, upscale shopping centers like Barra Shopping, and sleek restaurants create a cosmopolitan atmosphere, yet the area maintains a friendly, welcoming vibe. Nature lovers will appreciate the nearby Reserva Marapendi, a lush green sanctuary teeming with hiking trails, birdwatching opportunities, and scenic views of the lagoon.
One must-visit spot is the iconic Pedra Bonita, where you can take in sweeping panoramas of Rio’s landscape—oceans, mountains, and cityscape all in one breathtaking vista. For a splash of local culture, explore the vibrant street art and lively cafes that dot the district, offering a taste of Barra’s eclectic spirit.
Whether you’re seeking a relaxing beach day, outdoor adventures, or a taste of Rio’s modern luxury, Barra da Tijuca’s inviting atmosphere and stunning views make it a must-visit district that captures the best of both nature and city life.
