How Didi’s Open‑Source Strategy Powers AI‑Driven Mobility

Intelligent Mobility Open Platform

Didi’s Intelligent Mobility Open Platform, created under the “Qunyan Plan”, is an AI‑focused open‑source platform that aggregates Didi’s AI algorithms, services, computing resources, and solution libraries for the smart‑mobility domain.

Open‑Source Projects (Recent Year)

Within the past year Didi released 20 open‑source projects on GitHub, accumulating close to 40 000 stars and involving more than 130 contributors. The projects span the following technical areas:

Artificial intelligence and machine‑learning frameworks

Middleware and distributed systems

Operations‑monitoring tools

Mini‑program SDKs

Mobile development libraries

Front‑end frameworks

Databases and storage engines

Open‑Source Governance

Didi has established an internal Open‑Source Committee that defines and enforces a set of open‑source management standards. Governance operates on a dual‑track model:

Formal mechanisms : project‑level review, licensing compliance, and release processes.

Operational incentives : multi‑dimensional support (technical, documentation, community outreach) and dedicated funding pools that allow project teams to operate autonomously.

This structure encourages both rapid internal adoption and healthy external community interaction.

External Contributions to Established OSS Projects

Didi actively contributes patches to major open‑source ecosystems. In 2018 the company submitted 53 patches to projects such as HDFS, Hive, Spark, Yarn, Flink, and Druid.io. Additional contributions include:

OpenMessaging – 1 Technical Steering Committee (TSC) member, leadership of the RocketMQ RIP‑7 design and implementation.

Linux kernel – 15 patches.

QEMU – 3 patches.

DPDK – 5 patches.

Ceph – over 20 patches and a Project Management Committee (PMC) role.

Didi also holds one PMC and two Committer positions across these ecosystems.

Community Memberships and Collaborative Activities

Didi joined the Linux Foundation in 2018 and subsequently became a founding member of the LFDL Foundation, as well as a member of the CNCF and Ceph foundations. The company co‑hosted the Gopher China 2019 conference with GoCN, and regularly sponsors or participates in events such as the China Open‑Source Conference, Flink Forward, and HBaseCon. Didi also collaborated with the China Academy of Information and Communications Technology to co‑author the “Open‑Source License Whitepaper” and the “Enterprise Open‑Source Governance Guide”.

Future Outlook

According to Didi’s Senior Vice President of R&D and Chair of the Open‑Source Committee, open source is the foundational layer of the internet industry. Didi plans to continue embracing openness, fostering win‑win collaborations, and contributing technical value together with the global open‑source community.
