 ## Upload your own GGUF
 Click the model badge or Models button. Upload a single GGUF v2/v3 file up to 6 GiB, then select it. Two uploads can be stored. Files are private, temporary and lost when the Space restarts. No remote Python code is accepted or executed. Compatibility depends on the bundled llama-cpp-python 0.3.19 CUDA runtime; split GGUFs, vision/audio and models that exceed the GPU memory or 120-second allocation are unsupported. Model loading is included in the same budget. Native GGUF initialization occurs inside the ZeroGPU worker, with GPU offload required and no CPU fallback. Chat requests retain the same account quota check and 180-second reserve. Remove models after any running reply finishes.

+## Coding workspace
+The Workspace button saves temperature, output length and optional coding/debugging instructions per selected model in this browser. Attach up to three UTF-8 code/text files (12,000 combined characters); their contents accompany messages while attached. Clear attachments when finished. Continue reply submits a continuation request in the active conversation. Input context supports up to 8,192 tokens; output remains capped at 4,096 with a 110-second generation window. The model weights are unchanged by this app update.
