• Construct a minimal native software to enter new textual content and retrieve sentiment predictions from the mannequin.
• Take a look at the complete pipeline end-to-end and refine steps for stability, accuracy, and effectivity.

24. OpenEngage: Construct an entire AI-driven advertising and marketing Engine

Challenge Hyperlink

This undertaking/course reveals you learn how to construct an end-to-end AI-powered advertising and marketing engine that automates customized buyer journeys, engagement, and marketing campaign administration. You learn the way giant language fashions (LLMs) and automation can rework conventional advertising and marketing workflows into scalable, data-driven, and customized advertising and marketing methods.

Key Abilities to Study

• How LLMs can be utilized to generate customized content material and tailor advertising and marketing messages at scale
• Designing and orchestrating buyer journeys — mapping person behaviours to automated engagement flows
• Constructing AI-driven advertising and marketing pipelines: knowledge seize, monitoring person behaviour, segmentation, and multi-channel supply (e mail, messages, and so on.)
• Integrating AI-based personalization with conventional advertising and marketing/CRM workflows to optimize engagement and conversions
• Understanding learn how to construct an AI advertising and marketing engine that reduces handbook effort and scales with the person base

Challenge Workflow

• Perceive the function of AI and LLMs in fashionable advertising and marketing methods and the way they will enhance personalization and engagement.
• Outline advertising and marketing aims and buyer journey — what campaigns, what person interactions, what personalization logic.
• Construct or configure the advertising and marketing engine’s elements: knowledge seize/monitoring, person segmentation, content material technology by way of LLMs, and supply mechanisms.
• Design automated pipelines that set off customized messages primarily based on person behaviour or segments, leveraging AI for content material and timing.
• Take a look at the pipelines with pattern customers/knowledge, monitor efficiency (engagement, response charges), and refine segmentation or content material logic.

25. Learn how to Construct an Picture Generator Net App with Zero Coding

Challenge Hyperlink

This undertaking guides you to construct an internet software that generates photos utilizing generative AI — all with out writing any code. It’s a drag-and-drop, no-programming route for anybody who desires to launch a picture generator net app shortly, utilizing prebuilt elements and interfaces.

Key Abilities to Study

• Understanding generative AI for photos: how AI fashions can create visuals from prompts
• Utilizing no-code or low-code instruments to construct net functions that combine AI picture technology
• Designing person interface and person circulate for an internet app with out coding
• Deploying a functioning net app that connects to an AI backend for real-time picture technology
• Managing picture enter/output, immediate dealing with, and person requests in a no-code setting

Challenge Workflow

• Select a no-code/low-code platform or device that helps AI picture technology + web-app constructing.
• Configure the backend with a generative AI mannequin (pre-trained) that may generate photos primarily based on person prompts.
• Design the front-end utilizing drag-and-drop UI elements: enter immediate discipline, generate button, show space for outcomes.
• Hyperlink the front-end to the AI backend: guarantee person inputs are handed appropriately, and generated photos are returned and displayed.
• Take a look at the app totally by submitting completely different prompts, checking output photos, and verifying usability and efficiency.
• Optionally deploy/publish the net app so others can use it (on a internet hosting platform or a web-app internet hosting service).

26. GenAI to Construct Thrilling Video games

Challenge Hyperlink

This undertaking teaches you learn how to construct enjoyable and interactive video games powered by Generative AI. You’ll discover how AI can drive sport logic, generate dynamic content material, reply to participant inputs, and create partaking experiences, all without having a complicated game-development background. It’s a inventive, hands-on approach to perceive how GenAI can be utilized past conventional knowledge or textual content functions.

Key Abilities to Study

• Making use of Generative AI fashions to design sport mechanics
• Integrating AI instruments/APIs to create dynamic, responsive gameplay
• Designing person interplay flows for AI-powered video games
• Dealing with prompt-based technology and various person inputs
• Constructing light-weight interactive functions utilizing AI because the core engine

Challenge Workflow

• Begin by selecting a easy sport idea the place AI technology provides worth — for instance, a guessing sport, storytelling problem, or AI-generated puzzle.
• Outline the sport loop: how the person interacts, what enter they offer, and what the AI generates in response.
• Combine a generative AI mannequin to supply dynamic content material, hints, storylines, or selections.
• Construct the interplay circulate: seize person enter, name the AI mannequin, format outputs, and return outcomes again to the participant.
• Take a look at the sport with completely different inputs, refine prompts for higher responses, and enhance the general gameplay expertise.
