Sophia — AI Assistant — A conversational AI research playground for memory, tool-use and multi-step planning.

Overview

Sophia, a conversational AI prototype exploring tool-calling, contextual memory over structured JSON state, and multi-step task planning with citations and recall.

Goals

  • Test whether an LLM can hold multi-turn task state reliably.
  • Give the assistant tools rather than only text output.
  • Keep memory inspectable instead of hidden in an embedding blob.
  • Build the agentic patterns later reused in J.A.R.V.I.S — NIX.

Approach & architecture

  1. 1

    Prompt orchestration

    Structured system prompts and templates separate role, tools and task state so behaviour stays predictable.

  2. 2

    Tool calling

    The model returns structured calls into a small tool set instead of free-form instructions.

  3. 3

    Lightweight memory

    Context is stored as structured JSON state, which is readable and diffable rather than opaque.

  4. 4

    Planning loop

    Multi-step tasks are decomposed, executed and re-checked against the original request.

Agent loop diagram: user request, structured system prompt, LLM reasoning engine, tool call registry, JSON memory state, planning step and a re-check and validate stage looping back until the goal is met.
Agent loop — structured prompting, tool calls, JSON memory and a re-check stage.
