-Version 2.1.2. Supported: Linux x86-64 and Windows x64 (MSVC), each with a CUDA 12 and a CUDA 13 build, as a full package and a `-system-cuda` package. Turing (compute capability 7.5, e.g. RTX 2080) is supported by builds configured with `-DMOSSINFER_SM75=ON` (the `windows-msvc-cuda13-sm75` preset packages it): fp16 tensor-core GEMMs replace the bf16 ones, INT8 and INT4 ConvRot files run the INT8 GEMMs, the exact attention and the VAE run sm_75 kernels, all three quality tiers work, and an unset attention resolves to `exact`. See [docs/sm75.md](docs/sm75.md) for what runs, the measured speed on an RTX 2080 Ti and the remaining gaps. Volta (Tesla V100, sm_70) is supported by the CUDA 12 `linux-cuda12-sm70` preset; see [docs/sm70.md](docs/sm70.md) for its kernels, validation and performance. Other GPUs (AMD, Intel, older NVIDIA) can run txt2img at the reference tier through `moss-infer-vulkan`, a separate and slower Vulkan program in its own package ([docs/vulkan.md](docs/vulkan.md)); on Linux, `moss-infer-hip`, a separate ROCm 7 program, runs it on AMD GPUs: built for gfx1100, gfx1200 and gfx1201 (Radeon RX 7900 and RX 9000), validated on gfx1200 (RX 9060 XT) ([docs/hip.md](docs/hip.md)). The full support matrix is in [docs/integration.md](docs/integration.md#support-status).

The full support matrix is in [docs/integration.md](docs/integration.md#support-status).
 
 The caller picks the quality tier: `reference` (bf16, exact), `high` (the loaded DiT's GEMMs with 8-bit attention) or `turbo` (a 4-bit DiT). An INT8 DiT with `high` is the everyday choice: 2.5 times the bf16 speed on an RTX 5090, in 40 % less VRAM ([performance](docs/integration.md#performance)). Upgrading from 1.x: [migration](docs/integration.md#migrating-from-1x).

 MossInfer is a low-level engine: it runs what the caller asks for, refuses what the hardware or the files cannot run with the reason, and reports what ran. It does not choose for the caller. The launcher picks the tier, the memory mode and the budgets; [Performance](#performance) says what each costs and gives.
