I recently created LlamaThink-8b-Instruct Full Instruct model

and a few of you were curious as to how I made it, here is the process to finetune a model with GRPO reinforcement learning.

So our goal is to make a thinker model, its super easy, first we need a dataset. Here is a script for llama cpp python to create a dataset.

Background

Cisco AIR-CAP3702I-E-K9 Wireless Access points, are (as of 2025) about 10 years old and largely redundant in the face of WiFi's evolution over the past decade. However, they still are useful for most Home/Home Office use cases as the 5Ghz througput is up to 1300mbps, and unless you have gigabit internet, then one of these could be a cheap way to extend your WiFi.

They can be purchased for about $10 off eBay (as of 2025) these days, and are cheaper than spending money on a new Wireless AP, when you probably don't need most of the requirements.

Converting an eBay Cisco AIR-CAP3702I-E-K9 to an Autonomous/Standalone AP

The Cisco AIR-CAP3702I-E-K9's sold on eBay will be most likely old infrastructure from an Office, and as such, will be running the wrong firmware for home use. They'll be running 'lightweight' firmware which means they AP's themselves are 'dumb

Using the Nortel / Avaya 1140e SIP Deskphone in 2026

This phone is like 20 years old, but it still works with your ISP's SIP service is configured correctly. Firstly, it's best to update to the latest available public firmware version, however do to this you'll probably need to factory reset it, and convert from UniStim to SIP firmware (version 2 or 3.2) prior.

Per this guide to factory reset:

You can factory reset a Nortel IP phone that is already running UNIStim firmware release 3.0 or later.  You will need to be running the following firmware at a minimum for this procedure to work;
IP 1110 (0623C6E), IP 1120E (0624C6E), IP 1140E (0625C6E), IP 1150E (0627C6E), IP 1210 (062AC6E), IP 1220 (062AC6E), IP 1230 (062AC6E), IP 2001 (0604DCD), IP 2002 (0604DCD), IP 2004 (0604DCD), and IP 2007 (0621C6D).

The UNIStim firmware release 3.0 for IP Phones introduces the ability to restore an IP Phone to a “factory default” configuration.
