The Eight-Gigabyte Threshold: IndexTTS 2.5 Fully Homesteaded, the Hardware Ledger of 104 Seconds for 6.5 Seconds, and the Two Self-Inflicted Wounds of One Bat File

The Bilibili open-source voice-cloning TTS IndexTTS 2.5 fully homesteaded on drive F: official repository clone, uv environment from the lockfile (PyTorch 2.8 + CUDA 12.8 correctly recognizing the RTX 3070), the 5.2GB main models plus 3.9GB auxiliary models downloaded in batches through the proxy, and the half-directory ghost of w2v-bert-2.0 exorcised (remains left by an interrupted first start fooled the existence check); the 8GB VRAM auto-selected BF16 half precision in low-VRAM mode — the correct posture, not a downgrade; field tests measured 104 seconds for 6.5 seconds of audio with s2mel alone at 85 — the hardware ledger of a 3070 running 2.5, which no bundle repack can change; and the self-written launcher bat inflicted two wounds on itself (the nonexistent --inbrowser argument, UTF-8 Chinese hints mangled by the GBK cmd), rewritten in pure ASCII with delayed browser open and verified.
