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 signifies that Claude now helps remembering over 75,000 strains of code, and even lots of 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 overlook the context because it hit the restrict. With as much as a 1 million context restrict, you’ll be able to construct higher apps, and Claude can bear in mind extra of your code than ever.
It’s price noting that the 1 million context restrict is restricted to Sonnet 4. Opus 4.1 nonetheless has the outdated limitations as a result of it is an costly mannequin.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 patrons with Tier 4 and customized fee limits, with broader availability rolling out over the approaching weeks.
“Lengthy context can also be accessible in Amazon Bedrock and is coming quickly to Google Cloud’s Vertex AI,” Anthropic famous.
“With 1M tokens you’ll be able to: load whole codebases with all dependencies, analyze lots of of paperwork without delay, and construct brokers that keep context throughout lots of of device calls. Pricing adjusts for prompts over 200K tokens, however immediate caching can scale back prices and latency.”
Claude’s cell and net apps will probably be getting the 1 million token context restrict in some unspecified time in the future sooner or later.
