Overview

Upsonic is an open-source AI agent framework for building production-ready agents. It supports multiple AI providers (OpenAI, Anthropic, Azure, Bedrock) and includes built-in safety policies, OCR, memory, multi-agent coordination, and MCP tool integration.

What Can You Build?

• Document Analysis: Extract and process text from images and PDFs
• Customer Service Automation: Agents with memory and session context
• Financial Analysis: Agents that analyze data, generate reports, and provide insights
• Compliance Monitoring: Enforce safety policies across all agent interactions
• Research & Data Gathering: Automate research workflows with multi-agent collaboration
• Multi-Agent Workflows: Orchestrate tasks across specialized agent teams

Quick Start

Installation

uv pip install upsonic
# pip install upsonic

Basic Agent

from upsonic import Agent, Task

agent = Agent(model="anthropic/claude-sonnet-4-5", name="Stock Analyst Agent")

task = Task(description="Analyze the current market trends")

agent.print_do(task)

Agent with Tools

from upsonic import Agent, Task
from upsonic.tools.common_tools import YFinanceTools

agent = Agent(model="anthropic/claude-sonnet-4-5", name="Stock Analyst Agent")

task = Task(
    description="Give me a summary about tesla stock with tesla car models",
    tools=[YFinanceTools()]
)

agent.print_do(task)

Agent with Memory

from upsonic import Agent, Task
from upsonic.storage import Memory, InMemoryStorage

memory = Memory(
    storage=InMemoryStorage(),
    session_id="session_001",
    full_session_memory=True
)

agent = Agent(model="anthropic/claude-sonnet-4-5", memory=memory)

task1 = Task(description="My name is John")
agent.print_do(task1)

task2 = Task(description="What is my name?")
agent.print_do(task2)  # Agent remembers: "Your name is John"

Key Features

• Autonomous Agent: An agent that can read, write, and execute code inside a sandboxed workspace, no tool setup required
• Safety Engine: Policy-based content filtering applied to user inputs, agent outputs, and tool interactions
• OCR Support: Unified interface for multiple OCR engines with PDF and image support
• Memory Management: Session memory and long-term storage with multiple backend options
• Multi-Agent Teams: Sequential and parallel agent coordination
• Tool Integration: MCP tools, custom tools, and human-in-the-loop workflows
• Production Ready: Monitoring, metrics, and enterprise deployment support

Core Capabilities

Autonomous Agent

AutonomousAgent extends Agent with built-in filesystem and shell tools, automatic session memory, and workspace sandboxing. Useful for coding assistants, DevOps automation, and any task that needs direct file or terminal access.

from upsonic import AutonomousAgent, Task

agent = AutonomousAgent(
    model="anthropic/claude-sonnet-4-5",
    workspace="/path/to/project"
)

task = Task("Read the main.py file and add error handling to every function")
agent.print_do(task)

All file and shell operations are restricted to workspace. Path traversal and dangerous commands are blocked.

Safety Engine

The Safety Engine applies policies at three points: user inputs, agent outputs, and tool interactions. Policies can block, anonymize, replace, or raise exceptions on matched content.

from upsonic import Agent, Task
from upsonic.safety_engine.policies.pii_policies import PIIAnonymizePolicy

agent = Agent(
    model="anthropic/claude-sonnet-4-5",
    user_policy=PIIAnonymizePolicy,  # anonymizes PII before sending to the LLM
)

task = Task(
    description="My email is john.doe@example.com and phone is 555-1234. What are my email and phone?"
)

# PII is anonymized before reaching the LLM, then de-anonymized in the response
result = agent.do(task)
print(result)  # "Your email is john.doe@example.com and phone is 555-1234"

Pre-built policies cover PII, adult content, profanity, financial data, and more. Custom policies are also supported.

OCR and Document Processing

Upsonic provides a unified OCR interface with a layered pipeline: Layer 0 handles document preparation (PDF to image conversion, preprocessing), Layer 1 runs the OCR engine.

uv pip install "upsonic[ocr]"

from upsonic.ocr import OCR
from upsonic.ocr.layer_1.engines import EasyOCREngine

engine = EasyOCREngine(languages=["en"])
ocr = OCR(layer_1_ocr_engine=engine)

text = ocr.get_text("invoice.pdf")
print(text)

Supported engines: EasyOCR, RapidOCR, Tesseract, PaddleOCR, DeepSeek OCR, DeepSeek via Ollama.

Upsonic AgentOS

AgentOS is an optional deployment platform for running agents in production. It provides a Kubernetes-based runtime, metrics dashboard, and self-hosted deployment.

• Kubernetes-based FastAPI Runtime: Deploy agents as isolated, scalable microservices
• Metrics Dashboard: Track LLM costs, token usage, and performance per transaction
• Self-Hosted: Full control over your data and infrastructure
• One-Click Deployment: Automated deployment pipelines

IDE Integration

Add Upsonic docs as a source in your coding tools:

Cursor: Settings → Indexing & Docs → Add https://docs.upsonic.ai/llms-full.txt

Also works with VSCode, Windsurf, and similar tools.
