LFM2.5-ExecuTorch

This repository hosts the **lfm-2.5** models exported for the React Native ExecuTorch library as ExecuTorch `.pte` programs, ready to run on device. `2_6b/` contains the instruction-tuned LiquidAI/LFM2.5-2.6B checkpoint, exported for chat assistants with an 8,192-token context and 128-token prefill chunks. Its chat template strips thinking from every assistant message when rendering history, matching Qwen3 and keeping incremental KV-cache prompts monotonic. Generation still starts with ` `. `tokenizer_config.json` contains the corrected template. Both XNNPACK and MLX artifacts were executed on a physical Apple Silicon Mac, including generation and the maximum prefill chunk size. See `2_6b/validation.json` for smoke-test results and `2_6b/export_manifest.json` for checkpoint provenance and SHA-256 hashes. The MLX artifact requires the React Native ExecuTorch MLX runtime from the software-mansion-labs ExecuTorch fork. The embedding lookup uses a portable int4 kernel; the decoder runs in one MLX partition.
