##Call for Papers


We invite submissions across five areas, including but not limited to:

01Secure Code Generation

  • Vulnerability-aware training and decoding
  • Guardrails: input filtering, output auditing, policy enforcement
  • Adversarial attacks: jailbreaks, prompt injection, obfuscation
  • Safety of agentic coding systems

02Trustworthiness

  • Explainability and interpretability of code models
  • Calibration, uncertainty, and hallucination
  • Contamination-aware benchmarks and evaluation
  • Human–CodeLLM and agent alignment

03Robustness

  • Paraphrasing, dialectal variation, and code-mixed prompts
  • Low-resource, emerging, legacy, and domain-specific languages
  • Adaptation to new languages and distribution shift

04Multilinguality

  • Generation, explanation, and documentation from non-English prompts
  • Cross-lingual transfer to new natural languages
  • Data curation for underrepresented languages

05Applications

  • Efficient code models for low-compute settings
  • Deploying code models across languages and communities
  • CodeLLMs in computing education
Reviewing
OpenReview, with an option to commit pre-reviewed ARR papers.
Format
One day, in person, hybrid. Authors who cannot travel can present remotely.
Venue
