While top-tier AI models have previously posted near-perfect scores, this result is drawing attention because it used fewer tokens than existing models. According to results posted on GitHub on Sunday, OpenAI's new GPT-6 Astra was the only evaluated model to score a perfect 450 in the 2026 CSAT LLM Solution Log.
