HER Hack-Astron #5 is now open. This challenge invites developers to turn a real Spark X2.5 run into a reproducible, useful edge-agent case. Use Spark X2.5-4B or Spark X2.5-1.7B, publish the complete case in the matching Hugging Face Discussions, and reply to the event Issue with the direct link.
What can you build?
Choose one direction or combine several:
- Agent workflows with Codex, Claude Code, OpenClaw, Hermes, or another harness
- Real repository fixes, online-judge tasks, and end-to-end coding agents
- Native 1M-context document or codebase tasks
- Multilingual understanding, generation, and translation
- GGUF quantization, throughput, TTFT/TPOT, and edge memory use
- Instruction following, mathematics, reasoning, and safety boundaries
- Hardware adaptation across NVIDIA, Ascend, Hygon, HOUMO.AI, and others
- Licensed-data SFT/RL experiments with honest before-and-after comparisons
How to enter
- Run a real experiment and record the pinned model revision, runtime, hardware, precision/quantization, and parameters.
- Keep representative inputs, raw Spark X2.5 outputs, logs or screenshots, metrics, failures, and limitations.
- Publish the full case in the Discussions section for the model you used. The title only needs to include HER Hack-Astron #5.
- Reply to the event Issue with the direct Discussion link.
