Laguna XS 2.1: New FREE + Opensource Local AI!
Julian reviews Laguna XS 2.1, a new free open-source local AI coding model from Poolside that performs comparably to Qwen 3.6 and outperforms Claude Haiku on benchmarks. He demonstrates its practical capabilities by building landing pages and functional apps, highlighting its speed, offline functionality, and multiple deployment options through local setup, Claude Code, or OpenRouter's free API.
Summary
Julian introduces Laguna XS 2.1, a newly released lightweight local AI model designed specifically for agentic coding and terminal work. The model features a 256K context window and is available for free on Hugging Face. According to benchmark comparisons, Laguna XS 2.1 performs close to Qwen 3.6 on SWE Bench Verified, outperforms Northstorm Mini Code, and surpasses Claude Haiku 4.5 on SWE Bench Pro and GPT-4o by significant margins. However, Julian emphasizes that benchmarks alone don't tell the full story and prefers practical demonstrations.
For practical testing, Julian created three different web applications using Laguna XS 2.1: a simple landing page that performed better than Gemma 4, a functional to-do list application with working add and delete features, and another web page. He notes that the UI quality is comparable to what Claude could produce a year ago, acknowledging that local models typically lag behind frontier models by approximately one year in capability. The generated code is functional and the model runs smoothly on a Mac Studio M4 Max with 36GB memory. Julian also notes the model is not suitable for 3D model generation.
Regarding accessibility and deployment, Laguna XS 2.1 can be used in multiple ways: integrated into Julian's local Agent OS engine, through free Claude Code, as a separate Hermes agent profile, or via OpenRouter's newly released free API. Running locally offers privacy benefits since all data remains on the user's machine and works offline. Julian promotes his AI Profit Room community, which provides the full Agent OS setup, daily tutorials on local models, coaching calls, and member-created projects like AI avatar video generation and automated lead generation systems using local models.
Key Insights
- Laguna XS 2.1 performs close to Qwen 3.6 on SWE Bench Verified and outperforms Claude Haiku 4.5 on SWE Bench Pro, demonstrating that local models can match or exceed some frontier models on specific benchmarks despite being lightweight.
- Local models typically lag behind frontier models by approximately one year in capability, as evidenced by Laguna XS 2.1 producing code quality comparable to what Claude could generate a year ago.
- Laguna XS 2.1 can be deployed through three distinct options: locally on a user's machine for privacy and offline use, through free Claude Code integration, or via OpenRouter's free API for users with hardware constraints.
- The model is not suitable for 3D model generation, limiting its applicability despite strong performance in agentic coding and web application development.
- Laguna XS 2.1 outperformed Gemma 4 when tested on a simple landing page creation task, and successfully generated fully functional applications like a to-do list app with working add/delete features.

[0:00] Today, we're going to be testing out a new local model called Laguna XS 2.1. And this is a model that seems to do pretty well. It's pretty fast and easy to use as well. We've already installed it and plugged it into our agent OS. I'll show you how it's working in a second, and it just got updated today. So, this has literally just dropped. It's available on Hugging Face, and it's pretty powerful from what I've seen so far. Now, it is quite a lightweight model. It's pretty chill to use. You can see how it performs right here on the benchmarks. So, you can see for example, [0:30] Laguna XS 2.1. There was a previous…
