Summary
“GPT-6 Astra introduced a new generation of intelligence; these models extend its benefits by making that intelligence more efficient and accessible,” the company writes. The first models in the Sol and Luna series were introduced earlier this year, representing different tiers in OpenAI’s hierarchy of models. OpenAI is also emphasizing big improvements in efficiency and affordability, most notably, via a substantial price drop for API access. OpenAI also claims that its newest models are better at producing answers that are factually accurate, and notes that they have a lower error rate when it comes to coding.
