An r/singularity post on March 13, 2026 highlighted Anthropic’s move to make 1M context generally available for Opus 4.6 and Sonnet 4.6, with standard per-token pricing, higher media limits, and automatic support in Claude Code tiers.
Anthropic says 1M context is now generally available for Opus 4.6 and Sonnet 4.6 with standard pricing, no long-context premium, and media limits expanded to 600 images or PDF pages. Hacker News treated the announcement as a practical deployment story rather than a simple spec bump.
A March 13, 2026 Hacker News thread focused on Anthropic's 1M context GA update for Claude Opus 4.6 and Sonnet 4.6, especially the removal of long-context premiums. The release also raises media limits to 600 images or PDF pages and rolls 1M context into Claude Code for Max, Team, and Enterprise users.
