Poetiq's self-improving harness pushes GPT-5.5 to 93.9% on coding benchmark
Poetiq just revealed results showing its Meta-System, a recursive self-improving harness, boosted GPT-5.5 to a record 93.9% on LiveCodeBench Pro without any model fine-tuning. The system automatically builds optimized execution scaffolding via standard APIs, lifting Gemini 3.1 Pro by 12.3% and outperforming Google's Deep Think. It shows external harnesses can unlock massive gains, though Poetiq remains waitlisted.
