|
"Upgrade the day 1 project to summarize a webpage to use an Open Source model running locally via Ollama rather than OpenAI\n", |
|
"\n", |
|
"You'll be able to use this technique for all subsequent projects if you'd prefer not to use paid APIs.\n", |
|
"\n", |
|
"**Benefits:**\n", |
|
"1. No API charges - open-source\n", |
|
"2. Data doesn't leave your box\n", |
|
"\n", |
|
"**Disadvantages:**\n", |
|
"1. Significantly less power than Frontier Model\n", |
|
"\n", |
|
"## Recap on installation of Ollama\n", |
|
"\n", |
|
"Simply visit [ollama.com](https://ollama.com) and install!\n", |
|
"\n", |
|
"Once complete, the ollama server should already be running locally. \n", |
|
"If you visit: \n", |
|
"[http://localhost:11434/](http://localhost:11434/)\n", |
|
"\n", |
|
"You should see the message `Ollama is running`. \n", |
|
"\n", |
|
"If not, bring up a new Terminal (Mac) or Powershell (Windows) and enter `ollama serve` \n", |
|
"And in another Terminal (Mac) or Powershell (Windows), enter `ollama pull llama3.2` \n", |
|
"Then try [http://localhost:11434/](http://localhost:11434/) again.\n", |
|
"\n", |
|
"If Ollama is slow on your machine, try using `llama3.2:1b` as an alternative. Run `ollama pull llama3.2:1b` from a Terminal or Powershell, and change the code below from `MODEL = \"llama3.2\"` to `MODEL = \"llama3.2:1b\"`" |
