GPT-6.1 Terra vs. GPT-6 Astra: One sacrifices accuracy for lower cost and higher speed at high effort
OpenAI's GPT-6.1 Terra is positioned as a high-volume, low-cost model priced at one-tenth the cost of GPT-6 Astra. While it offers significantly faster task completion in certain benchmarks, early tests indicate limitations in accuracy and a tendency to guess on unanswered questions.
Key points
- Terra costs $1 per million input tokens compared to Astra's $10.
- Terra is reported to be over three times faster than Astra in specific benchmarks.
- Accuracy varied across tests, with a 78.2% score in an accounting benchmark.
