Local AI

The purpose of this page is to document the process in running an AI environment locally. It also covers the experience as it is used throughout other projects which will introduce some crossover between projects.

Summary

The idea of running a model locally will pause for a bit. After around a day of testing, poking around, brushing up on prompt crafting, etc. it’s simply much more expedient to use something like ChatGPT online or possibly GitHub’s copilot.

If AI was the project then really digging into training it up, learning the ins and outs, etc. would be the next step. When OpenAI will already generate an accurate file in half a second from the same prompt? Eh, putting this on ice for breaking the standards on KISS and remaining flexible.

Discovery Round 1

The discovery process has been very simple: a search on duckduckgo.com for “windows local LLM ai” returned an article from Make Use Of. I’ve come across other content from this site before and decided, “Why not? Let’s see what happens.”

The top listing in the article is the Hermes GPTQ model which fits my major requirement of having something that excels at natural language processing, a perfect fit for my intention to run a slew of ARM templates, BICEP files, PowerShell scripts, etc. through something.

The search results also included a result for LM Studio which is a GUI front end for various LLMs. The Hermes model is included, as is pulling compatible models from the Hugging Face model repo.

Everything seems to check off the KISS principle

✔ No dependency hell between UI and back end
✔ Chat style interface similar to the online OpenAI tool
✔ Intuitive UI after ~5 minutes of poking around

Initial Impressions

After 10 minutes of use the application and model looked promising. I fed it one of the Azure deployment templates from a recent deployment and claimed is was a different sort of resource. It correctly identified that the ARM template was for something else, and prompted for the information it would need. Additional prompted didn’t go very smoothly however.

Feeding an ARM template and asking for a BICEP deployment file triggered some contextually correct requests (resource group name and location), however, it was unable to actually generate the BICEP file. The closest I got was receiving a copy of the ARM template that I fed it back.

Things didn’t seem nearly good enough, so additional information was needed. The version of the model chosen was a poor choice (not recommended) which was a little disappointing but the UI did have little “i” call outs on each model variant.

A recommended model version was then downloaded, however, it didn’t have any parameters set which the previous one had. Looking through various GitHUB projects, wiki’s, etc. eventually landed on the llama documentation on readthedocs.io. After setting various parameters to their defaults, modifying some parameters here and there, it’s starting to appear like it’s at least functional.

Discovery Round 2

Additional searches more specifically around code, local implementations, etc. pointed to the CodeLLAMA model. Downloading and using the codellama-13b-instruct.Q5_K_M.gguf looks very promising. Defaults parameters were pre-populated and the first run output something that, at first glance, looks promising.

Additional time playing around with the model ultimately resulted in confusion. There’s a mixture of operator error (my crafting of the prompts) but also some interesting hallucinating going on with the model injecting.

Can you generate a Bicep file that will create a virtual network named “vnet-testing-westus2”, use the “10.1.1.1/24” address space, with two subnets. The first subnet should be named “gateway” and use the 10.1.1.1/28 subnet range. The second subnet should be called “snet-test-vms” and use the 10.1.1.8/26 subnet range. All resources should inherit their location from the resource group they are deployed in. The file should have a default resource group of “rg-test-westus2” which is already created and located in the WestUS2 location.

Can you generate a Bicep file that will create a virtual network named “vnet-testing-westus2” and use the “10.1.1.0/24” address space? The address space will include three subnets. The first subnet should be named “gateway” and use the 10.1.1.240/28 subnet range. The second subnet should be called “snet-test-lan” and use the 10.1.1.0/25 subnet range. The third subnet should be named “snet-test-dmz” and use the 10.1.1.128/26 subnet range. All resources should inherit their location from the resource group they are deployed in. The file should have a default resource group of “rg-test-westus2” which is already created and located in the WestUS2 location. Rules need to be added to the “snet-test-lan” subnet blocking any access from the “snet-test-dmz” subnet range.

AI The file should also include a route table named “rt-testing-westus2” which will have two routes defined in it. The first route is named “rte-testing-westus2” and uses the next hop type of “VirtualAppliance”. The second route is named “rte-testing-westus2-default” and uses the next hop type of “Internet”.

The file should also include a network security group named “nsg-testing-westus2” which will have two rules defined in it. The first rule is named “rule-testing-westus2” and allows traffic from any source address to any destination port 80. The second rule is named “rule-testing-westus2-default” and denies all traffic from the “snet-test-dmz” subnet range to any destination port.

The file should also include a virtual network gateway named “vng-testing-westus2” which will use the “Standard” sku, the “Vpn” type, and the “RouteBased” routing type. The gateway should be created in the “rg-test-westus2” resource group.

The file should also include a virtual network gateway connection named “vngc-testing-westus2” which will use the “vng-testing-westus2” virtual network gateway and the “Vnet2Vnet” connection type. The connection should be created in the “rg-test-westus2” resource group.

The file should also include a local network gateway named “lng-testing-westus2” which will use the “10.1.1.0/24” address space and have an IP address of “192.168.1.1”. The gateway should be created in the “rg-test-westus2” resource group.

The file should also include a virtual network gateway connection named “vngc-testing-westus2-lng” which will use the “vng-testing-westus2” virtual network gateway and the “IPSec” connection type. The connection should be created in the “rg-test-westus2” resource group

The conversation ends there with regenerate/continue regurgitating the previous responses; basically going around in circles. Settings on the output randomness (temp) and playing with additional parameters may fine tune the responses. However, this is deviating too far from the main goal - using locally running AI as a tool. It’s breaking standards around keeping things simple and having the tech work for me.

Still not 100% correct (at first glance the scope of a resource group is at the subscription level and typically separated out) but an amazing starting point.
