| # Hugging Face Spaces installs from this file at build time. |

| # Note: gradio is intentionally NOT listed here. HF Spaces auto-installs |
| # `gradio[oauth,mcp]==<sdk_version>` on top of this file based on the SDK |
| # selection in README.md frontmatter. Listing it here causes a pip |
| # version-conflict at build time when our pin disagrees with HF's. |

| # torch >= 2.0 for the scaled_dot_product_attention path. CPU-only is |
| # fine on free Spaces. |
| torch>=2.0.0 |

| # tiktoken is the GPT-2 BPE backend the GhostTokenizer wraps. |
| tiktoken>=0.5.0 |

| # huggingface_hub for hf_hub_download. The v0.9 chat weights and the |
| # RAG index both live in the Models repo Ghostgim/GhostLM-v0.9-experimental |
| # (not in the Space's own LFS) so the Space stays within the 1 GB |
| # free-tier cap. Pulled and cached on first launch. |

| # transformers + sentencepiece for the BGE-small-en-v1.5 retrieval |
| # embedder used by the RAG layer. transformers is already pulled in |
| # transitively but listing it explicitly pins the version range we test |

| # numpy for the in-memory retrieval index (83K x 384 float32 matrix). |

| # Python 3.13 removed the stdlib audioop module that gradio's transitive |
| # pydub dep imports at module-load time. Without this the entire gradio |
| # import chain fails with ModuleNotFoundError: No module named |
| # 'pyaudioop'. The PEP 594 replacement is audioop-lts. Conditional so |
| # 3.12 and earlier (where stdlib audioop still exists) skip it. |
