What is an LLM (Large Language Model)?

• Core Concept:
• LLMs predict the next word in a sequence based on user prompts.
• These predictions rely on probabilities derived from extensive training data.
• Behavior of LLMs:
• Consistency: Outputs often remain the same unless adjusted by temperature settings.
• Temperature: Determines the randomness of predictions.
• Foundation of LLMs:
• Based on the transformer model introduced in the 2017 research paper, Attention is All You Need.
• The transformer algorithm selects specific features during training to improve learning outcomes.

Types of AI Models

1. Closed Weighted Models:
• Parameters are fixed, and the code cannot be edited.
2. Open Weighted Models:
• Parameters can be adjusted and fine-tuned.
3. Open Source Models:
• Code is public and fully editable.

Steps to Create an AI Model

1. Visit Kaggle to select a suitable model.
2. Choose a Gemma model compatible with Keras and other tools.
3. Understand the model versions:
• Differ based on parameter weights, inputs, and instructions.
4. Select the database and credentials (tokens).
5. Copy the code to the appropriate editor.
6. Use the Keras library and API key for integration.
7. Fine-tune the model's weights.
8. Summarize data:
• Use an API to fetch news and extract relevant content.
9. Enter the prompt for summarization using the integrated API.

Running Gemma Locally

• Tools and Frameworks:
• Ollama.com, GPT4All.io, ImStudio.ai, Llama.cpp.
• Example: Ollama Framework:
• A serving framework for building AI agents.
• Provides a platform to implement and test agent interfaces.

DevOps: Selecting the Right Computing Model

Key Questions for Decision-Making:

1. What will I manage?
2. What will the cloud manage?
• Example: If focusing on software alone, choose PaaS.

Computing Models Explained

• On-Premises: The user manages the entire infrastructure, including hardware, software, and networking. It offers complete control but requires more maintenance.
• IaaS (Infrastructure as a Service): Provides virtualized computing resources like servers and storage managed by the cloud provider, while the user configures the OS and applications.
• CaaS (Containers as a Service): Focuses on managing container orchestration and runtime environments, simplifying containerized application deployment.
• PaaS (Platform as a Service): Offers a managed platform for app development, including runtime, middleware, and tools, allowing developers to focus on code.
• FaaS (Function as a Service): A serverless computing model where functions are executed based on events, eliminating server management.
• SaaS (Software as a Service): Delivers fully managed software applications over the internet, requiring no user infrastructure management.

Google Cloud Computing Models

1. Google App Engine:
• For stateless applications using HTTP protocols.
2. Cloud Migration with VMs:
• Ensures consistent performance by monitoring CPU functions.
3. Serverless (FaaS):
• For applications triggered by specific events or signals.

Key Factors to Consider in Cloud Computing

1. Pricing

• Coordinate with the management team to assess budget and pricing requirements.
• Use the Google Pricing Calculator to estimate the overall cost of computing resources.

2. Scalability

• Analyze traffic patterns and request volumes.
• Types of Scaling:
• Horizontal Scaling: Automatically duplicates instances to handle increased loads.
• Vertical Scaling: Manually upgrades CPU and other resources for better performance.

3. Cloud Models Without Servers

• Serverless models operate on an event-driven basis.
• Example: Cloud Run deploys instances only during event execution, with storage remaining consistent.

Google Compute Options

1. Standard: Fixed resources (CPU, database storage, etc.), irrespective of usage.
2. Committed and Sustained: Reserved or sustained usage discounts (details unclear).
3. Preemptible VMs: Low-cost virtual machines with limited availability, reassigned after use.
4. Serverless: Operates on execution or triggered events, not persistent computing.

Decision Tree for Cloud Model Selection

• Developing Event-Driven Applications?
• Yes → Use FaaS (Serverless).
• No → Does the application require a specific OS, GPU, or full infrastructure control?
• Yes → Use IaaS (for full control over VMs and infrastructure).
• No → Is the application containerized or planned for containerized deployment?
• Yes → Do you plan to use Kubernetes or container orchestration?
• Yes → Use CaaS (for managed container environments).
• No → Use PaaS (for simplified platform-based deployments).
• No → Use PaaS (for a fully managed app platform).

Building AI Applications with Flutter

Flutter and Dart Overview

• Flutter:
• A cross-platform, open-source UI toolkit developed by Google.
• Compiles native code using Dart.
• Dart:
• A programming language that runs within the Flutter framework.

Key Features of Flutter

• Widgets:
• Fundamental building blocks of Flutter applications.
• Contain parameters, variables, and values.
• Array:
• Used to store data in sections within a single variable.
• In Flutter, arrays are stateful, meaning data leaving the array is displayed on the user’s screen.

Creating a Virtual Assistant with Flutter and Gemini

Integration Workflow

1. Build the virtual assistant with Flutter.
2. Use Gemini as the AI engine for responses.
3. Key Components:
• List View: To display chat history.
• Input Field and Button: onPressed() function sends data for processing.
• setState() Function: Updates the display with user and AI responses.

API Integration

• Add the API Key and API Secret Token to the getAnswer() function.
• Fetch the API details from Google AI Studio and connect them to Gemini.

Text-to-Speech (TTS) Library

• Combines Android and iOS TTS features into a single library.
• Functions:
• textToSpeech() for processing.
• speak() for audible responses.
• The library supports on-premises use for improved human-like voices.

Animations with Rive Platform

• Rive: Platform for creating character animations based on user interactions.
• Workflow:
• Upload animation files to Google AI Studio.
• Link animations to Flutter code using related functions.
• Example: Character reacts while the user types input.

Synchronizing Speech and Animations

• Use the TTS Listener Function:
• Detects when the speech ends.
• Stops character animations once text playback is complete.

Firebase Overview

2. Another AI agent evaluates the response.
3. The system selects the best response for the user based on evaluations.

Advanced Firebase Integration

Connecting Firebase with PostgreSQL

• To integrate Firebase Data Connect with PostgreSQL:
1. Set up a connection between Firebase and PostgreSQL for real-time data synchronization.
2. Use Firebase Extensions or third-party tools to enable seamless integration.
3. Evaluate data traffic patterns and optimize queries for efficient processing.
