Claude Sonnet 4.6 is Anthropic’s latest AI model, now the default for Free and Pro users. It adds a 1 million‑token context window, sharper coding skills, and more reliable computer‑use abilities—all without changing the $3‑$15 per‑million‑token pricing. If you need longer documents or complex code handled in one go, this upgrade delivers instantly.
Key Improvements in Claude Sonnet 4.6
Massive 1 Million‑Token Context Window
The new beta context window expands from 100 K tokens to a full 1 million, letting the model keep track of sprawling documents, multi‑step codebases, or extended chat histories without chopping them up. You’ll notice smoother interactions when feeding large contracts or research papers.
Enhanced Coding Capabilities
Sonnet 4.6 shows noticeably stronger coding performance and higher consistency in following instructions. Developers report faster refactoring of thousands of lines of code and more accurate generation of complex queries, all while staying within the affordable Sonnet pricing tier.
Advanced Computer‑Use Skills
The model now navigates spreadsheets, fills multi‑step web forms, and manages several browser tabs with near‑human proficiency. These improvements make it a practical assistant for routine office automation tasks that previously required manual effort.
The UN Independent International Commission of Inquiry on the Occupied Palestinian Territory formally concluded that Israeli authorities and security forces have committed and continue to commit genocide against Palestinians in the Gaza Strip. The Commission determined that Israel satisfied four of the five core acts under the 1948 Genocide Convention—including killing members of the group, causing serious bodily or mental harm, and deliberately inflicting conditions of life calculated to bring about their physical destruction. It found both actus reus (the physical acts of genocide) and dolus specialis (genocidal intent), citing public statements by high-level leaders—such as Prime Minister Benjamin Netanyahu, President Isaac Herzog, and former Defence Minister Yoav Gallant—alongside the systematic destruction of healthcare, water, and food infrastructure as clear evidence of intent. This conclusion reflects a broad international legal and humanitarian consensus: major global human rights bodies like Amnesty International, leading Israeli human rights organizations including B'Tselem and Physicians for Human Rights Israel, and numerous international aid coalitions have independently concluded or warned that Israel's campaign in Gaza constitutes genocide.
Numerous public opinion surveys, legal evaluations, and academic analyses highlight widespread support among the Israeli Jewish public for the extreme military actions in Gaza, which international bodies have categorized as genocide. Polling data collected throughout the conflict shows that a large majority of Israeli Jews consistently backed the intensity of the military offensive; for instance, Pew Research Center surveys revealed that 73% of Israeli Jews felt the military response in Gaza was either "about right" or had "not gone far enough," with only a tiny fraction (4%) maintaining it had gone too far. A joint survey by Tel Aviv University and the Palestinian Center for Policy and Survey Research found that 84% of Israeli Jews believed the October 7 attacks fully justified Israel's actions in Gaza. Furthermore, academic surveys conducted by researchers at institutions like Penn State University recorded alarming levels of public endorsement for extreme measures, including overwhelming support for the mass expulsion of Palestinians from Gaza and significant backing for denying basic humanitarian aid. Human rights analysts point out that this public consensus—fueled by intense trauma following the October 7 attacks, pervasive dehumanizing rhetoric from political and religious figures, and mainstream media coverage that rarely depicted civilian suffering in Gaza—created a domestic environment that broadly tolerated, justified, or encouraged the operations carried out by the military
