What Google Gemini 3.6 Flash and Laguna S2.1 Are
Google Gemini 3.6 Flash and Laguna S2.1 are two new AI models released the same week. Gemini 3.6 Flash is Google's fastest, most efficient model, not its biggest. Laguna S2.1 is from a company called Poolside and is a Mixture of Experts model that runs on a single desktop.
Both models show where AI is heading: speed and efficiency. Gemini 3.6 Flash uses 17% fewer tokens than the old version, 3.5 Flash. Fewer tokens mean faster answers and less waste. Laguna S2.1 has 118 billion parameters but only activates 8 billion at a time. That keeps it fast and light.
Key Features of Gemini 3.6 Flash and Laguna S2.1
Gemini 3.6 Flash is better at coding. It scored 49% on the Deep SWE test, up from 37% for the old model. Google also released two smaller models: 3.5 Flashlight and 3.5 Flash Cyber. Flashlight is built for speed and scored 54% on Terminal Bench, double the old Lite model. Cyber is for security but not public yet.
Google is building computer use into the model. That means the AI can click buttons and fill fields without extra setup. Laguna S2.1 is small enough to run on a DGX Spark desktop. It scores 78.5% on SWE-Bench Multilingual and 40.4% on Deep SWE. Poolside published all trial results, which is rare.
- Faster token use
- Better coding scores
- Computer use built-in
- Local desktop run
How to Get Started with These AI Models
Getting started is simple. Both models are available now. Gemini 3.6 Flash is on Google's platform. Laguna S2.1 can be downloaded and run on a single machine.
- Sign up for Google's AI service or access Gemini 3.6 Flash.
- For Laguna S2.1, download the model from Poolside's website.
- Set up a DGX Spark desktop if you want to run Laguna locally.
- Start with a simple task like drafting text or fixing a bug.
No data center needed for Laguna. Just one desktop machine. For Gemini, you can use it through the API or a chat interface. Both models are designed to be easy to start with.
How to Use Them: Real Examples from the Episode
In the episode, Julian showed practical uses. For a landing page, use Gemini 3.6 Flash to draft it, test five headlines, and rewrite the whole page. This takes the time you used to spend on one paragraph.
For emails, draft ten different versions. Pick the one that sounds like you and send it quickly. With Laguna S2.1, you can run it locally to automate tasks like tagging new signups or checking form entries. This keeps data off the cloud.
- Drafting and testing copy
- Rewriting pages fast
- Automating repetitive tasks
- Running coding tasks
These models make it faster to test more ideas. The speed changes what you can do daily.
Benchmark Results and Comparisons
Benchmarks show big improvements. Gemini 3.6 Flash scored 49% on Deep SWE, up from 37%. The old Lite model scored 31% on Terminal Bench, but 3.5 Flashlight scored 54%, nearly double.
Laguna S2.1 scored 70.2% on Terminal Bench 2.1. That test requires the AI to use a real computer terminal. It also scored 78.5% on SWE-Bench Multilingual, top of the board. On Deep SWE, it scored 40.4%, compared to DeepSeek-Fi 4-Pro-Max's 9%.
When Thinking Mode is off, Laguna drops to 60.4% on Terminal Bench and 16.5% on Deep SWE. That shows reasoning is key. Poolside released three models in three months, and this one went from start to release in under 9 weeks.
Tips, Limits, and Mistakes to Avoid
One mistake is turning off Thinking Mode on Laguna. It makes the model faster but much less capable. The reasoning step checks the model's work. Keep it on for important tasks.
Gemini 3.6 Flash is not the smartest model. It's the fastest and most efficient. Don't expect it to beat bigger models on complex reasoning. Use it for speed.
- Keep Thinking Mode on
- Use the right model for the task
- Check published results
- Be careful with security models
3.5 Flash Cyber is not public yet. It could be misused, so Google is careful. Also, Gemini 3.5 Pro is still in testing, not shipped. Expect updates soon.
Who These Models Are For and Why They Matter
These models are for business owners, developers, and small teams. If you test landing pages, write emails, or do coding, they save time. The gap between large companies and small ones is shrinking.
With Laguna S2.1, you don't need a cloud subscription or data center. You can run it in your office. That means small teams can do real coding work without a big budget.
Google's computer use feature removes technical setup steps. Anyone running automations can benefit. These models make speed a daily tool. Faster means you test more ideas and get more done.
