Lightning Core API Index¶

This page is the quick index for public API surfaces.

Python API (PyPI package)¶

Primary import:

import lightning_core as lc

Main Python surfaces:

• Runtime helpers: backend_name, runtime_capability, runtime_trace_*, runtime_sync_*
• Runtime timeline helper: runtime_trace_timeline (sorting/grouping/hotspot summary, including group_by="op_path" for dispatch bottlenecks)
• Tensor ops: vector_add, matrix_add, matrix_sub, matmul2d, conv2d_nchw
• Attention: attention2d, attention_forward, AttentionSession
• Integrated API namespace: lc.api.* (clean operation names for conv/attention/integrated paths)
• Engine federation surfaces: set_engine/get_engine, *_runner_adapter_schema, create_*_model_runner_adapter, import_export_compatibility_matrix, engine_federation_policy_v3_schema
• Modular facade package (split-in-progress): lightning_core_api.bridges, lightning_core_api.checkpoint
