The full GPT-5.6 family goes live today for all users: Luna at $1/$6/Mtok for high-volume work, Terra at $2.50/$15 for production, and Sol at $5/$30 with a new "ultra" mode that deploys subagents to tackle complex tasks at up to 750 tokens/second on Cerebras.
Why it matters: A budget tier (Luna) finally puts near-frontier intelligence within reach for high-volume content and outreach workflows; Sol's "ultra" subagent mode is the first official multi-agent runtime from OpenAI.
SpaceXAI's latest goes public with a 500K context window, trained alongside Cursor, priced at $2/$6 per million tokens vs. Opus 4.8's $5/$25 — accessible immediately to all Cursor plan tiers.
Why it matters: Grok 4.5's Cursor integration makes it instantly available to dev teams already in the IDE, and its pricing sharpens the cost case for agentic coding workflows.
Superhuman merged Coda's flexible doc surface with a rebuilt AI layer on July 8 — describe a tracker, brief, or status update in plain language and AI builds it inside the doc; a new private-beta Databases layer handles up to 1M rows.
Why it matters: For marketing ops teams already on Coda/Superhuman, the integrated AI layer removes the friction of exporting to a separate tool for analysis, proposals, and structured tracking.
