|
||
|
||
Here are some practical examples:
|
||
|
||
```sh
|
||
aichat # Start REPL
|
||
|
||
aichat -e install nvim # Execute
|
||
aichat -c fibonacci in js # Code
|
||
|
||
aichat -s # REPL + New session
|
||
aichat -s session1 # REPL + New/Reuse 'session1'
|
||
|
||
aichat --info # View system info
|
||
aichat -r role1 --info # View role info
|
||
aichat -s session1 --info # View session info
|
||
|
||
cat data.toml | aichat -c to json > data.json # Pipe stdio/stdout
|
||
|
||
aichat -f data.toml -c to json > data.json # Send files
|
||
|
||
aichat -f a.png -f b.png diff images # Send images
|
||
```
|
||
|
||
### Shell commands
|
||
|
||
Simply input what you want to do in natural language, and aichat will prompt and run the command that achieves your intent.
|
||
|
||
```
|
||
aichat -e <text>...
|
||
```
|
||
|
||
|
||
|
||
AIChat is aware of OS and shell you are using, it will provide shell command for specific system you have. For instance, if you ask `aichat` to update your system, it will return a command based on your OS. Here's an example using macOS:
|
||
|
||
```
|
||
$ aichat -e update my system
|
||
? sudo softwareupdate -i -a
|
||
```
|
||
|
||
The same prompt, when used on Ubuntu, will generate a different suggestion:
|
||
```
|
||
$ aichat -e update my system
|
||
? sudo apt update && sudo apt upgrade -y
|
||
```
|
||
|
||
### Shell integration
|
||
|
||
This is a **very handy feature**, which allows you to use `aichat` shell completions directly in your terminal, without the need to type `aichat` with prompt and arguments. This feature puts `aichat` completions directly into terminal buffer (input line), allowing for immediate editing of suggested commands.
|
||
|
||
|
||
|
||
To install shell integration, go to [./scripts/shell-integration](https://github.com/sigoden/aichat/tree/main/scripts/shell-integration) to download the script and source the script in rc file. After that restart your shell. You can invoke the completion with `alt+e` hotkey.
|
||
|
||
### Generating code
|
||
|
||
By using the `--code` or `-c` parameter, you can specifically request pure code output.
|
||
|
||
|
||
|
||
**The `-c/--code` option ensures the extraction of code from Markdown.**
|
||
|
||
## Chat REPL
|
||
|
||
AIChat has a powerful Chat REPL.
|
||
|
||
REPL Features:

|
||
```
|
||
|
||
### `.info` - view information
|
||
|
||
- `.info`: View system information
|
||
- `.info role`: view your current role information.
|
||
- `.info session`: view your current session information.
|
||
|
||
### `.model` - change the current LLM
|
||
|
||
```
|
||
> .model openai:gpt-4
|
||
> .model ollama:llama3
|
||
```
|
||
|
||
> Tab autocompletion helps in quickly typing the model names.
|
||
|
||
### `.role` - switch to a specific role
|
||
|
||
Select a role:
|
||
|
||
```
|
||
> .role emoji
|
||
```
|
||
|
||
Send message with the role:
|
||
|
||
```
|
||
emoji> hello
|
||
👋
|
||
```
|
||
|
||
Leave current role:
|
||
|
||
```
|
||
emoji> .exit role
|
||
|
||
> hello
|
||
Hello there! How can I assist you today?
|
||
```
|
||
|
||
Temporarily use a role without switching to it:
|
||
```
|
||
> .role emoji hello
|
||
👋
|
||
|
||
>
|
||
```
|
||
|
||
### `.session` - Begin a chat session
|
||
|
||
By default, aichat behaves in a one-off request/response manner.
|
||
|
||
You should run aichat with `-s/--session` or use the `.session` command to start a session.
|
||
|
||
|
||
```
|
||
> .session
|
||
|
||
temp) 1 to 5, odd only 0
|
||
1, 3, 5
|
||
|
||
temp) to 7 19(0.46%)
|
||
1, 3, 5, 7
|
||
|
||
temp) .exit session 42(1.03%)
|
||
? Save session? (y/N)
|
||
|
||
```
|
||
|
||
### `.prompt` - create a temporary role using a prompt
|
||
|
||
There are situations where setting a system message is necessary, but modifying the `roles.yaml` file is undesirable.
|
||
To address this, we leverage the `.prompt` to create a temporary role specifically for this purpose.
|
||
|
||
```
|
||
> .prompt your are a js console
|
||
|
||
%%> Date.now()
|
||
1658333431437
|
||
```
|
||
|
||
### `.file` - read files and send them as input
|
||
|
||
```
|
||
Usage: .file <file>... [-- text...]
|
||
|
||
.file message.txt
|
||
.file config.yaml -- convert to toml
|
||
.file screentshot.png -- design a web app based on the image
|
||
.file https://ibb.co/a.png https://ibb.co/b.png -- what is the difference?
|
||
```
|
||
|
||
> The capability to process images through `.file` command depends on the current model’s vision support.
|
||
|
||
### `.rag` - chat with your documents and knowledge bases.
|
||
|
||
```
|
||
> .rag test1
|
||
> Select embedding model: openai:text-embedding-3-small
|
||
> Set chunk size: 2000
|
||
> Add document paths: tmp/files/paul_graham_essay.txt
|
||
✨ Saved rag to '<user-config-dir>/aichat/rags/test5.bin'
|
||
|
||
#test1> What did the author do growing up?
|
||
The author mainly focused on writing and programming growing up ...
|
||
```
|
||
|
||
### `.set` - adjust settings (non-persistent)
|
||
|
||
```
|
||
.set max_output_tokens 4096
|
||
.set temperature 1.2
|
||
.set top_p 0.8
|
||
.set rag_top_k 4
|
||
.set rag_minimum_score 0
|
||
.set function_calling true
|
||
.set compress_threshold 1000
|
||
.set dry_run true
|
||
```
|
||
|
||
## Local Server
|
||
|
||
AIChat comes with a built-in lightweight web server.
|
||
|
||
```
|
||
$ aichat --serve
|
||
Chat Completions API: http://127.0.0.1:8000/v1/chat/completions
|
||
LLM Playground: http://127.0.0.1:8000/playground
|
||
LLM ARENA: http://127.0.0.1:8000/arena
|
||
|
||
$ aichat --serve 0.0.0.0:8080 # to specify a different server address
|
||
```
|
||
|
||
### OpenAI format API
|
||
|
||
AIChat offers the ability to function as a proxy server for all LLMs. This allows you to interact with different LLMs using the familiar OpenAI API format, simplifying the process of accessing and utilizing these LLMs.
|
||
|
||
Test with curl:
|
||
|
||
```sh
|
||
curl -X POST -H "Content-Type: application/json" -d '{
|
||
"model":"claude:claude-3-opus-20240229",
|
||
"messages":[{"role":"user","content":"hello"}],
|
||
"stream":true
|
||
}' http://127.0.0.1:8000/v1/chat/completions
|
||
```
|
||
|
||
### LLM Playground
|
||
|
||
The LLM Playground is a webapp that allows you to interact with any LLM supported by AIChat directly in your browser.
|
||
|
||
|
||
|
||
### LLM Arena
|
||
|
||
The LLM Arena is a web-based platform where you can compare different LLMs side-by-side.
|
||
|
||
|
||
|
||
## Function Calling
|
||
|
||
Function calling supercharges LLMs by connecting them to external tools and data sources. This unlocks a world of possibilities, enabling LLMs to go beyond their core capabilities and tackle a wider range of tasks.
|
||
|
||
We have created a new repository to help you make the most of this feature: [https://github.com/sigoden/llm-functions](https://github.com/sigoden/llm-functions)
|
||
|
||
Here's a glimpse of what function calling can do for you:
