Setup complexity: Advanced
Poolside provides open-weight foundation models for agentic coding. It offers the Laguna family of models, including a lightweight version for on-device execution and a larger, more capable model accessible via API for advanced software development.
Comparison

Best Poolside alternatives

Poolside vs. GitHub Copilot: Choose GitHub Copilot for its seamless integration into IDEs like VS Code and its strength in line-by-line code completion and function generation; it's optimized for developer productivity in the flow of work. Choose Poolside when your goal is to automate complex, multi-step 'agentic' tasks that go beyond simple completion. Poolside's open-weight models, especially the on-device Laguna XS, offer greater control, transparency, and the ability to build custom automation agents, making it ideal for researchers and teams building bespoke AI-driven development tools rather than just using one.

The decision

Is Poolside worth it?

Return on investment
By automating complex, multi-day refactoring tasks with the Laguna M.1 API, a development team could save dozens of engineering hours per project.

Who It's For

Why Software Development choose this tool

🎯
Built for
It's best for developers and researchers who require transparent, powerful, and adaptable agentic models for automating complex coding tasks.
In-Depth Overview
For software developers focused on AI-driven automation, Poolside offers a distinct advantage with its 'open-weight' agentic coding models. Unlike closed-source alternatives, Poolside provides direct access to its Laguna model family. The Laguna XS 2.1 is a 33B parameter model optimized to run on-device, giving you local, private, and fast coding assistance without relying on cloud APIs. For more complex, long-horizon tasks, the Laguna M.1 offers 225B parameters of power, accessible via API and through platforms like OpenRouter. The company's 'work in the open' philosophy is backed by an extensive blog series, 'The Model Factory,' detailing their research on training, evaluation, and reinforcement learning from code execution. This transparency allows developers to understand the engineering behind the models, providing deeper insight than a typical black-box tool. This makes Poolside a strong choice for developers who want to not just use AI for coding, but to build with, understand, and even refine the underlying models themselves.
