how to use

How to Use nanobot

Getting started with nanobot involves setting up the open-source framework and configuring it to interact with desired LLM providers and communication channels. The process is designed for rapid deployment, often taking minutes to hours.

1Install the nanobot framework, typically via Python package managers or by cloning the GitHub repository.
2Configure API keys for preferred Large Language Model (LLM) providers (e.g., OpenAI, Anthropic) that nanobot will integrate with.
3Set up desired communication channels, such as Telegram, Discord, or Slack, by configuring gateway settings.
4Define custom tools and skills for the AI agent to utilize, such as web search or file operations.
5Utilize the built-in web interface (Workbench Release v0.2.1) for agent development, testing, and runtime adjustments.
6Deploy the nanobot agent for personal use, team collaboration, or workflow automation.

pricing

nanobot Pricing & Plans

nanobot operates on a freemium and open-source model, meaning the core framework is available at no cost. Users are responsible for any costs incurred from the underlying Large Language Model (LLM) providers that nanobot integrates with.

Freemium: Free access to the core nanobot framework.
Open-source: Free access to the source code for self-hosting and modification.

Pros

+Ultra-lightweight core (approx. 4,000 lines of Python) for high auditability and efficiency.
+Minimal memory footprint (<20MB median RSS on startup) suitable for edge devices.
+Open-source and self-hostable, providing users with full ownership and control.
+Rapid deployment and extensibility through a modular plugin system.
+Comprehensive support for integration with numerous chat applications and LLM providers.
+Features like long-horizon execution and scheduled automations for complex workflows.

Cons

−Relies on external LLM providers, incurring their respective usage fees and rate limits.
−May have a smaller skill ecosystem and fewer integrated platforms compared to more feature-rich, larger frameworks.
−The /v1/chat/completions API endpoint currently lacks rate limiting, potentially leading to exhaustion of LLM provider credits.
−Requires technical expertise for setup, configuration, and customization.
