Anthropic has raised the context window for Claude Sonnet 4 to one million tokens on the Anthropic API, Amazon Bedrock, and soon Google Cloud Vertex AI. This is five times larger than before, letting users process entire codebases or large sets of research documents in a single run. The change is primarily for developers working with extensive source code or those who need to summarize large volumes of text. The one million token context is currently in public beta for customers with Tier 4 or custom API limits.

The expanded context window comes with steeper pricing. For requests over 200,000 input tokens, Anthropic charges $6 per million tokens, double the usual rate. Output tokens cost $22.50 per million, up from the standard $15. Anthropic points to prompt caching and batch processing as ways to cut costs, with batch processing potentially lowering expenses by up to 50 percent.
Anthropic's Claude can now remember previous conversations with users and build on them over time. The new feature works much like ChatGPT's memory function, but puts a stronger emphasis on continuing and using information from earlier chats. According to Anthropic, the feature is now live for users on the Enterprise, Team, and Max plans, with support for other plans coming soon.

Reddit is heavily restricting the Internet Archive's access to its platform.
Going forward, the Wayback Machine will only be able to index Reddit's homepage, blocking access to individual posts, user comments, and profile pages. According to company spokesperson Tim Rathschmidt, the move is a response to incidents where AI companies scraped Reddit content via the Wayback Machine, violating the platform's rules. Reddit notified the Internet Archive ahead of time, and the new restrictions are being rolled out immediately.
The change is part of a broader push by Reddit to crack down on data scraping and free data use by AI firms. In 2024, Reddit signed licensing deals with Google and OpenAI for access to its data, while blocking search engines that don't pay. The company has also filed a lawsuit against Anthropic over alleged unauthorized data scraping for AI training.
