Devika AI Working

Devika AI works like a smart assistant for various tasks, designed to make complex processes simpler.

Here’s a breakdown of how it operates:

User Interface: Think of this as the face of Devika, where you interact with it. It’s a web-based chat interface where you can talk to Devika, check project files, and see what it’s up to.

Agent Core: This is the brain of Devika. It handles all the planning, decision-making, and execution processes. It talks to different parts of Devika to get things done efficiently.

Large Language Models: Devika is equipped with some really smart language models like Claude, GPT-4, and Local LLMs via Ollama.

Planning and Reasoning Engine: It takes big goals you give to Devika and breaks them down into smaller, manageable steps. It then decides the best way to tackle these steps based on what’s happening.

Research Module: When Devika needs more information to complete a task, it can search the web for relevant data.

Code Writing Module: This is where Devika’s coding skills come into play. If your task involves coding, Devika can generate code based on the plan it made and the information it found. It’s like having a coding buddy who writes code for you.

Browser Interaction Module: Devika can also surf the web! It can navigate websites, grab information, and interact with different parts of web pages. This comes in handy for tasks that require online research or data extraction.

Knowledge Base: This helps it work more efficiently and provide better assistance based on past experiences.

Database: All the project-related data, Devika’s state, and settings are stored in a database. This ensures that Devika remembers where it left off and can pick up tasks seamlessly.
