Ollama-Buddy V0.5.1 - Session/History/Role Management, Real-Time Token Tracking and More!

I’ve been a busy little bee in the last few days, so quite a few improvements to ollama-buddy, my Emacs LLM ollama client, they are listed below:

<2025-03-07 Fri> 0.5.1

Added temperature control

This addition gives users fine-grained control over the creativity and randomness of their AI responses through a new temperature variable.

This update adds several convenient ways to control temperature in Ollama-Buddy:

Key Features

  1. Direct Temperature Setting: Use C-c t from the chat buffer or the menu command [T] to set an exact temperature value between 0.0 and 2.0.

  2. Preset Temperatures: Quickly switch between common temperature presets with C-c T from the chat buffer:

    • Precise (0.1) - For factual responses
    • Focused (0.3) - For deterministic, coherent outputs
    • Balanced (0.7) - Default setting
    • Creative (0.9) - For more varied, creative responses

  3. Reset to Default: Return to the default temperature (0.7) with C-c 0 or the menu command [0].

  4. Visual Feedback: The current temperature is displayed in the header line and before each response, so you always know what setting you’re using.

<2025-02-28 Fri> 0.2.4

Added model-specific color highlighting

This enhancement aims to improve user experience by visually distinguishing different AI models within the interface.

Note: I am likely to use both colour and color interchangeably in the following text! :)

Key Features

  1. Model-Specific Colors

    • A new customizable variable, ollama-buddy-enable-model-colors, allows users to enable or disable model-specific colors.
    • Colors are generated based on a model’s name using a hashing function that produces consistent and visually distinguishable hues.
    • However there could be an improvement regarding ensuring the contrast is sufficient and hence visibility maintained with differing themes.

  2. Interactive Color Toggle

    • Users can toggle model-specific colors with the command ollama-buddy-toggle-model-colors, providing flexibility in interface customization.

  3. Colored Model Listings

    • Model names are now displayed with their respective colors in various parts of the interface, including:
      • The status line
      • Model selection menus
      • Command definitions
      • Chat history headers

Added Prompt History Support

Key Features

<2025-02-27 Thu> 0.2.2

Added support for role-based presets

This enhancement allows you to create, switch, and manage role-specific command configurations, which basically generates differing menu layouts and hence command options based on your context, making your workflow more personalized and efficient.

What Are Role-Based Presets?

Roles in Ollama Buddy are essentially profiles tailored to specific tasks. Imagine you’re using Ollama Buddy for:

With this update, you can now create presets for each of these contexts and switch between them seamlessly without manually re-configuring settings every time. On each switch of context and hence role, a new ollama buddy menu will be generated with the associated keybinding attached to the relevant context commands.

Key Features

1. Store Your Custom Roles

A new directory ollama-buddy-roles-directory (defaulting to ~/.emacs.d/ollama-buddy-presets/) now holds your role presets. Each role is saved as an .el file containing predefined commands, shortcuts, and model preferences.

2. Easily Switch Between Roles

With M-x ollama-buddy-roles-switch-role you can pick from available role presets and swap effortlessly between them (or use the menu item from ollama-buddy-menu)

3. Create Custom Roles with Unique Commands

You can now define custom commands for each role with M-x ollama-buddy-role-creator-create-new-role (or the menu item from ollama-buddy-menu)

This interactive function allows you to:

Once saved, your new role is ready to load anytime!

4. Open Role Directory in Dired

Need to tweak a role manually? A simple, run M-x ollama-buddy-roles-open-directory or of course also from the ollama-buddy-menu which opens the presets folder in dired, where you can quickly edit, copy, or delete role configurations.

5. Preconfigured presets are available if you’d like to use a ready-made setup.

If these files are put in the ollama-buddy-roles-directory then the role selection menu will pass through completing-read, and present the following:

{buffy | default | developer | janeway | translator | writer}

With the selection regenerating the ollama-buddy-menu accordingly, and off you go.

6. Menu commands

The following commands have been added to the ollama-buddy-menu:
