Product announcements, model updates, company news, and launch notes from the Cyrus team for teams adopting AI development agents.

Anthropic says Commerce has lifted export controls on Claude Fable 5 and Mythos 5, and that it will begin restoring access on July 1. Here's what changed and what to watch next.

Fable, a Mythos-class model, is now available on Cyrus as a Claude model option. Teams can choose it from Behaviours or try it on individual Linear issues with the fable label before assigning the issue to Cyrus.

Every company runs on knowhow trapped in heads, Slack threads, and Notion pages. Skills are how you make that knowhow legible to your Cyrus, with a curated library, custom skills, and per-session scope so each session only loads what's relevant. AI isn't bolted on; it's how your team already works.

The strongest coding model just got stronger. Opus 4.7 sharpens the agentic judgment, code review, and planning that made 4.6 great — and it's now the default on every Cyrus agent. Here's what it means for your team.

You're in a Slack thread. You type @cyrus. It answers. Instantly. In the thread. Because it's already connected to your Linear, your GitHub, your repos. No new tools. No new workflows. It just plugs in.

Your PRs shouldn't sit for days waiting for a review. You can now @mention Cyrus directly on any GitHub pull request and get an instant, thorough code review — edge cases caught, architectural trade-offs questioned, concrete improvement suggestions.

That feature that was going to wait till next week? It ships before lunch. Cyrus now runs Cursor Composer (250 tokens/sec) and OpenAI Codex (77.3% Terminal-Bench accuracy) — giving you the speed and flexibility to choose the right model for each task.

Anthropic's most capable coding model is here. Opus 4.6 brings a 1M token context window, agent teams, and adaptive thinking - and it's now the default for every Cyrus agent. Here's what it means for your team.

Security has always been foundational to how we build Cyrus. Today, we're proud to announce SOC 2 Type I compliance, independently verified by Prescient Security. Here's what this means for our users.
