  1. This sounds quite similar to dirac which made a stir a few months ago: https://github.com/dirac-run/dirac I spent way too long trying to reproduce the results in Pi and failing before I decided that I shouldn't trust author benchmarks for…

  2. …how to run a custom harness against this? There are none on the linked page. I want to run Dirac ( https://github.com/dirac-run/dirac ).

  3. …a plug, but relevant. I recently added a 'build native tools on the fly' functionality to Dirac ( https://github.com/dirac-run/dirac ) that works like: 1. You can use the '/new-tool' and tell what kind of tool you want (including whether…

  5. …initial greedy approach. A few months ago, I did a full benchmark run of 7 agents over 8 tasks ( https://github.com/dirac-run/dirac has the data and traces). I cannot claim neutrality because of the obvious connection to one of those, but…

  6. Dirac ( https://github.com/dirac-run/dirac , https://dirac.run/ ) now supports gpt-5.6. This thing does now seem to be on the chatGPT/codex accounts yet. UPDATE: it is now available in chatGPT account also, they rolled it out

  7. …to Mitchell. Since Ghostty is written in Zig, I ended up adding native Zig AST support in Dirac ( https://github.com/dirac-run/dirac/blob/master/src/services/... ) One thing the has been a little unintuitive is the pattern of all code and…

  14. It uses tree-sitter wasms. Currently, 14 languages are available ( https://github.com/dirac-run/dirac/tree/master/src/services/... ) The agent would work even without a language parser, just that the AST-based functionalities won't work
