DeepSeek open-sources core API engine, excluding key service components

DeepSeek has open-sourced the core engine of its API, releasing production kernels, speculative decoding, and deterministic sampling under the Apache 2.0 license.

IMPACT Enables developers to build upon DeepSeek's core technology, potentially fostering innovation in AI applications.
