Claude Code 100% GRATIS - Come usarlo SENZA PAGARE (anche su computer economici)

How to Use Claude Code for Free

Introduction to Claude Code

• The video discusses how to use Claude Code without any cost, presenting two setups: one that maximizes power and another that prioritizes privacy.

• The speaker notes common mistakes in existing guides that lead to failures when attempting more complex tasks.

Using Alternative Models

• To use Claude Code for free, alternative models must be utilized since Claude's own models are not available at no cost.

• These alternative models are open-weight and powerful, allowing full free usage while still leveraging Claude Code's capabilities.

Setup for Maximizing Power

• The unique feature of Claude Code is its agentic capabilities—reading, creating, and modifying files—regardless of the model used.

• For the first setup, users need Claude Code and a service called Open Router to access various AI models at no charge.

• Users should download Google Antigravity as it provides an environment for using Cloud Code and setting up the initial configuration.

Creating Settings File

• A prompt is provided to create a settings file that instructs Cloud Code to utilize Open Router models instead of its default ones.

• After creating the settings.json file, users must replace placeholders with their API key and chosen model name from Open Router.

Running Commands in Terminal

• Once updated, users can launch the terminal via Command J or Control J and execute commands using their selected model on Open Router.

• An example test command creates a text file with specific content successfully without incurring costs.

Privacy Considerations

• While this setup works well for functionality, it raises privacy concerns as data is sent to Open Router servers.

Setup Optimized for Privacy

Introduction to Ollama

• A second setup focuses on privacy by utilizing Ollama, which allows downloading AI models that run locally on a computer without internet access.

Selecting Models in Ollama

• Users can choose suitable AI models from Ollama by activating specific options or asking other AI tools like ChatGPT for recommendations based on their system specifications.

Downloading Local Models

• Important: Avoid selecting cloud-based models; they won't function locally. Instead, copy code snippets into Antigravity’s terminal to download local-compatible models.

Context Window Adjustment

• By default, Ollama has a context window of 4000 tokens which may prevent proper functioning. Adjusting this setting to 32000 tokens allows better interaction with Cloud Code's system prompts.

Successful Testing Post Adjustment

• After adjusting the context window size, tests show successful creation of files again. This highlights the importance of correct settings in ensuring functionality within Cloud Code.
