Unsloth Studio caps context length to prevent system swapping

A local LLM user is hitting hard VRAM limits in Unsloth Studio when trying to maximize context length for Gemma 4 26B, as the software automatically scales down context to prevent system RAM swapping. The user is seeking a way to bypass these guardrails by modifying the underlying llama.cpp python wrappers.

// ANALYSIS

Unsloth Studio's "safe defaults" approach protects mainstream users from catastrophic Out-Of-Memory (OOM) errors, but frustrates power users who want to push their hardware to the absolute limit.

–The UI enforces a conservative safety margin (e.g., leaving 2.2GB free on a 16GB VRAM card) rather than allowing the user to dictate exact VRAM allocation.
–Swapping LLM layers to system RAM drastically degrades inference speed, which is why Unsloth implements strict guardrails against it.
–This highlights a tension in local AI tooling between user-friendly, foolproof interfaces and the granular control offered by raw backends like llama.cpp.
