Third-party notices Kapitsa (Copyright 2026 Nace AI, Apache-2.0, see LICENSE) includes the following third-party code and data, each under its own license. Model weights are not part of Kapitsa: they keep their own licenses. The benchmark corpus (bench/harness/corpus/bench_corpus.txt, embedded in the kapitsa binary for `kapitsa bench`): excerpts of eight source files of Hugging Face Transformers (src/transformers/models/*/modeling_*.py: granite_speech, modernvbert, altclip, xcodec, t5, ctrl, emu3, videoprism), Apache License 2.0 (the text is in LICENSE). Each excerpt keeps its file's copyright and license header: Copyright 2018-2026 The HuggingFace Inc. team, Illuin Technology and contributors, The BAAI Teams Authors, Mesh TensorFlow authors and T5 Authors, Salesforce, NVIDIA CORPORATION. Changes: each file cut to its first 20,000 characters under a "### FILE: " heading and a code fence, the whole cut to 144,500 characters. Used only as prompt text, never executed. Details: bench/harness/corpus/NOTICE.md. ================================================================================ Splash (Inco), Apache License 2.0 https://github.com/incoai/splash The private AppleNeuralEngine interface declarations and method-signature table in src/ane/ane.mm and the ane_rotate_block helper in src/kernels/ane_ffn.metal are adapted from Splash. Their file headers note the changes. Review reference: be3b083c5f413673d44e44881042e875e674e333 (not an assertion of the original import revision). The Apache License 2.0 text is included in LICENSE. These portions remain under Apache-2.0. ================================================================================ MLX (Apple), reference designs and format compatibility, MIT License https://github.com/ml-explore/mlx MLX is credited for attention and matrix-fragment layouts, affine quantization formats and reference quantization behavior. Kapitsa does not link to the MLX runtime. See the per-file comments. MLX's license notice is reproduced below to accompany that credit. MIT License Copyright © 2023 Apple Inc.
