Claude Sonnet 4 has been upgraded, and it may well now bear in mind as much as 1 million tokens of context, however solely when it is used by way of API. This might change sooner or later.
That is 5x greater than the earlier restrict. It additionally implies that Claude now helps remembering over 75,000 strains of code, and even a whole lot of paperwork in a single session.
Beforehand, you had been required to submit particulars to Claude in small chunks, however that additionally meant Claude would neglect the context because it hit the restrict. With as much as a 1 million context restrict, you may construct higher apps, and Claude can bear in mind extra of your code than ever.
It’s value noting that the 1 million context restrict is proscribed to Sonnet 4. Opus 4.1 nonetheless has the previous limitations as a result of it is an costly mannequin.
Solely API will get 1 million tokens context restrict
The brand new context restrict is rolling out by way of the Anthropic API for purchasers with Tier 4 and customized fee limits, with broader availability rolling out over the approaching weeks.
“Lengthy context can be accessible in Amazon Bedrock and is coming quickly to Google Cloud’s Vertex AI,” Anthropic famous.
“With 1M tokens you may: load complete codebases with all dependencies, analyze a whole lot of paperwork without delay, and construct brokers that keep context throughout a whole lot of instrument calls. Pricing adjusts for prompts over 200K tokens, however immediate caching can scale back prices and latency.”
Claude’s cellular and internet apps can be getting the 1 million token context restrict in some unspecified time in the future sooner or later.
46% of environments had passwords cracked, practically doubling from 25% final yr.
