AI-generated solutions for the One Billion Row Challenge in multiple programming languages.

The easiest way to get the correct versions of all compilers/interpreters is to use Nix with flakes:

nix develop

This will drop you into a shell with all the required tools at the correct versions.

If you prefer not to use Nix, install the following tools at these versions:

Not included in Nix (requires separate installation):

• Jai: beta 0.2.018 - Proprietary compiler, requires beta access from thekla.com

The solutions expect a sample.txt file at the repository root. To generate this file:

1. Clone the original 1BRC repository:

   git clone https://github.com/gunnarmorling/1brc.git
   cd 1brc

2. Follow their instructions to generate the measurements file:

   ./create_measurements.sh 1000000000

3. Important: The script creates measurements.txt, but these solutions expect sample.txt. Rename or copy the file:

   cp measurements.txt /path/to/1brc-ai-results/sample.txt

Each language has normal, performant, and performance-aware variants in projects/<language>/.
