History

Historical Context

In February 2019 OpenAI announced GPT-2, a 1.5-billion-parameter model released in stages after concerns about misuse. The prior year Google’s BERT had achieved 84 % accuracy on the GLUE benchmark, showing commercial viability of transformer models. Those precedents underpin today’s token-based pricing, such as Moonshot AI’s $3 per million-token rate for Kimi K3.
