30% Depth of Action - Executes real work, not just summaries or chat
30% Context Quality - Pulls from multiple real sources and uses them intelligently
40% Workflow Usefulness - Would a team actually run this on Monday?

d_model (dmodel.ai) is a fundamental AI research lab focused on RLVR, interpretability, and agents to automate the path to an aligned superintelligence.

We're hosting a track for the Alignment & Mechanistic Interpretability Track.

What we’re looking for:
• Real, non-trivial use of advanced reasoning in real-world scenarios
• Creative applications beyond obvious LLM demos
• K2 Think V2 as a core part of your product, not a side API call

Description:
Build with one of the most capable open reasoning systems available. K2 Think V2 is a 70B-parameter model purpose-built for reasoning from the ground up — excelling at complex, multi-step problem solving across mathematics, science, coding, logic, and simulation. It features expanded context for sustained reasoning over large bodies of information, and is fully open end-to-end: pre-training data, post-training recipes, checkpoints, and evaluations are all publicly available and independently reproducible.
