Hello.
The main topics for this week are:
- The announcement of the large model: Claude Opus 4.5
- Expansion of model options in GitHub Copilot
- AWS's massive investment in AI infrastructure for the government
and so on.
As we head towards the end of the year, major updates from various companies are continuing. In particular, the announcement of Claude Opus 4.5 has reignited the competition for high-end models. Also, the speed at which it is being integrated into development tools (such as GitHub Copilot) is remarkable.
As a developer, I want to pay attention not only to the performance of the models but also to the fact that "mechanisms connecting AI and systems" like MCP (Model Context Protocol) are starting to be provided officially by AWS.
Notes
- Mainly focuses on AI and Web-related news collected recently
