Poetiq's Self-Optimizing Harness Surpasses Opus 4.7 on LiveCodeBench Pro Without Fine-Tuning

r/singularity·high signal

Poetiq's Meta-System automatically constructs and optimizes coding harnesses through recursive self-improvement. On LiveCodeBench Pro, it boosted Gemini 3.1 Pro by 12.3% (78.6 to 90.9), overtaking GPT 5.5's previous best. Applying the same harness to GPT 5.5 without new optimization pushed accuracy to 93.9%. The harness is model-agnostic and requires no fine-tuning — a demonstration that recursive meta-optimization can beat frontier models.
