Erik Thorelli and Erfan Al-Hossami evaluate OpenAI's GPT-6 Astra for its performance in code reviews, highlighting significant improvements in catching bugs within complex, cross-file contexts. While the model demonstrates superior reasoning capabilities compared to predecessors like Sol and Opus 5, it comes with a significantly higher API cost per task. The authors also explore how these advanced reasoning abilities might transfer to other tasks such as research synthesis or operational investigation, while addressing critical privacy considerations regarding data retention.
- Astra caught 33% more actionable bugs in hard cross-file reviews than Opus 5.
- Standard Astra API rates are $10 per million input tokens and $50 per million output tokens.
- An illustrative task using 100k input/10k output tokens costs ~$1.50 on Astra, compared to only $0.60 for GPT-5.6 Sol.
- CodeRabbit used Astra's autonomy to develop a complete action RPG titled NIGHTSHIFT in Godot.
