Some important landmarks since GPT4 was first released (not in chronological order):

- Vast cost reduction (>10x)

- Performance parity of several open source models to GPT4, including some with far fewer parameters

- Much better performance, much larger context window in state-of-the-art closed source LLMs (Claude 3.5 Sonnet)

- Multimodality (audio and vision)

- Prototypes for semi-autonomous agents and chain-of-thought architectures showing promising avenues for progress
