- UncleOxidant 5mo agoI unleashed it on a compiler codebase that I've been developing for several months now using Claude Sonnet 4.5/6, Gemini 3.1 Pro, DeepSeek V4 Pro(recent), and a bit of Qwen3.6-27B. Right away Fable found several longstanding bugs in our compiler that we hadn't found before. It found that there was a critical part of our design that needed to be mostly redesigned/rewritten and gave a very well-reasoned rationale for doing so.
- rajveerb 5mo agowhat sort of compiler?
- UncleOxidant 5mo agoA compiler that takes C code (a subset of C with some extensions) and compiles it to microcode for a type of microcoded, algorithmic state machine that we're developing.
- rajveerb 5mo agoit would be cool to have this task (or some variant) in a benchmark.
- viking123 5mo agoIt's worse than gpt 5.5 xhigh
- baq 5mo agoThe jagged frontier strikes again. I’d say it’s overall better, but not universally better.
