FlagOS Challenge
SEASON 02 · REGISTRATION OPEN JULY 19, 2026

Optimize the stack that runs across every chip.

The FlagOS Open Computing Global Challenge unites developers worldwide to push large-model inference performance across the FlagOS system software stack — from operator to end-to-end deployment. Season 2 is co-hosted with IEEE, SGLang, and OpenBMB.

One open stack, many chips

The FlagOS Community brings together research institutions, chip companies, system vendors, and software ecosystem partners to build an open-source system software stack for diverse AI chips — an operator library, a cross-chip compiler, a parallel training and inference framework, and a cross-chip communication library, all built around "develop once, deploy across chips."

Season 1 closed in June 2026 across three tracks — operator development, multi-chip inference throughput, and long-context data annotation — and established the organizational foundation for what comes next. Season 2 narrows the focus to two deep tracks and widens the ecosystem: SGLang as the exclusive inference-framework partner, OpenBMB's MiniCPM5-2B as the target model, and IEEE co-hosting.

01 — Tracks

Two tracks, two layers of the stack

Each team competes in exactly one track. Once you submit to a track, that choice is locked.
TRACK 01 · OPERATORS
SGLang operator performance across multiple chips
Migrate and optimize 200+ commonly used SGLang operators for correctness and speed across multiple AI chip platforms — exclusive collaboration with the SGLang framework.

What to know before you register

01

Eligibility

Open to anyone, individually or in teams of up to 5. One participant identity per person for the whole competition; register only through the official site.

02

Track selection

Pick one track. Submitting locks your track — no switching, and duplicate submissions across tracks are invalidated.

03

Originality

Work must be your own. Cite any third-party or open-source code you build on and make sure you have rights to use it.

04

Compute usage

Provided compute is for competition experiments only — no lending, mining, or unrelated workloads.

05

Submission format

Follow each track's official format and submit through the designated channel before the deadline. Late or malformed submissions aren't evaluated.

06

Conduct

No content involving security threats, discrimination, or privacy violations. Harassment results in disqualification at the organizers' discretion.
