According to CoinMeta, OpenAI announced at its annual developer conference the launch of new GPT-6.1 SOL models, priced at $2 per million tokens (mtok), with a sale price of $10 per million tokens, which is one-fifth of the price of the GPT-6 Astra models. This is expected to promote the development of high-frequency applications. The CEO of OpenAI, Sam Altman, stated that the SOL model represents a major upgrade, featuring robust professional capabilities and computer interaction performance. At the same time, OpenAI also announced that it will cease the use of GPT-6.1 Astra due to security and alignment issues. This move marks the second training suspension for the company within three months.
