✔ GPT-5.1 Model Support

With version 5.1, Admin Companion now supports the new gpt-5.1 model.

This upgrade means more depth in reasoning, better handling of complex scenarios, and improved generation of shell commands.

✔ Improved Handling of Long Command Outputs

We’ve optimized how the system processes very large outputs:

Long logs, verbose outputs, or multi‐step operations are now less likely to lose context or make the assistant “forget” what came before.

✔ OS Type and Release Detection Fix

Version 5.1 also fixes edge cases where OS detection failed on certain distributions and versions.

Admins working across diverse Linux environments will appreciate more accurate distro recognition.

Why This Matters for You

With these changes, Admin Companion is even better positioned for real-world sysadmin tasks. The benefits include:

  • Deeper reasoning: GPT-5.1 allows for more context‐rich and precise command suggestions.

  • Better stability: Long sessions and heavy outputs can now be processed with stronger memory retention.

  • Broader compatibility: Improved OS detection means smoother experience across Debian, Ubuntu, RHEL, Fedora and similar.

  • Still human-in-the-loop: While the underlying model improves, our core principle remains unchanged: You approve every command before it executes.
