Perfect! I've successfully retrieved the summary report for your project. The report shows a performance analysis for Pull Request #725 in the llama.cpp repository (auroralabs-loci).

Key Highlights:

1. Most Critical Issue: The std::vector::end() function shows a significant 226% increase in response time (from 81.11ns to 264.40ns)

2. Affected Areas: Most performance impacts are in STL container operations, particularly:

   • Vector operations
   • Hash table operations
   • Tree and deque operations

3. Interesting Pattern: While response times increased, throughput also increased in most cases, which might indicate changes in parallelization or workload distribution

4. Top Recommendation: Investigate changes to vector iteration patterns and STL container usage in PR UPSTREAM PR #18420: model: add Qwen3-Omni Thinker support (qwen3omnimoe) #725

Would you like me to provide more detailed information about any specific function or aspect of this performance analysis?
