Aircall just shipped 3 AI products: Outbound AI Agent, AI Actions, and Messaging AI Agent. The only platform unifying inbound voice, outbound voice, and SMS/WhatsApp — no stitching required.
AI Actions executes inside HubSpot, Zendesk, and Shopify mid-call — zero lines of code. Outbound AI Agent calls leads the moment intent signals. Messaging AI Agent handles SMS and WhatsApp 24/7. 250+ integrations, works on existing numbers. No infrastructure setup.
Today's AI headlines are stacked. Anthropic shipped its highest-capability public model yet, Cursor revealed a custom-trained model plus two entirely new products, and a well-funded stealth startup is betting that smarter organizational memory slashes token costs by up to 99%. Meanwhile, Google DeepMind is navigating a high-profile talent exodus as its transformer co-author and a Nobel laureate both defect to rivals.
Today's Top Stories
Anthropic Ships Claude Fable 5 — Its Most Capable Public Model YetAnthropic released Claude Fable 5 as part of a new "Mythos class" of models sitting above Claude Opus in capability. Fable 5 is broadly available, while its sibling Mythos 5 — identical under the hood but with cybersecurity guardrails removed — is restricted to government and security partners via Project Glasswing. Fable 5 was included free on Pro and Team plans through June 22; token-based pricing kicked in June 23, with Anthropic promising a return to subscription inclusion once capacity allows. Source →
Anthropic Launches Claude Tag — an Always-On AI Teammate for SlackClaude Tag is now in research preview for Enterprise and Team customers, adding a layer of persistent context and ambient intelligence to Slack that prior integrations couldn't match. Its standout feature is an ambient mode that proactively monitors assigned channels, flags relevant information from across the organization, and follows up on stalled tasks without being explicitly asked. Anthropic says it's working to bring Claude Tag to additional platforms in the coming weeks. Source →
Cursor Announces Its Own AI Model, a New Git Platform, and a Mobile AppAt a company event, Cursor's co-founders revealed their first fully custom-trained model — built from scratch using 10–20× the compute of prior Cursor models and targeting general availability within weeks. They also announced Origin, a Git platform engineered to handle thousands of simultaneous AI agent commits with automatic conflict resolution, and Cursor Mobile, an iOS beta for remotely managing and unblocking agents. The announcements mark Cursor's clearest push yet to become a full-stack development platform. Source →

Early partners include Microsoft (integrating with M365), Notion, and legal AI firm Harvey. Source →
Google DeepMind Loses Transformer Co-Author and Nobel Laureate to RivalsIn a striking week for AI talent movement, Noam Shazeer — co-author of the landmark 2017 "Attention Is All You Need" paper and the subject of Google's $2B+ acqui-hire of Character.ai — announced he is leaving for OpenAI. Days later, John Jumper, who shared the 2024 Nobel Prize in Chemistry for AlphaFold, said he is departing for Anthropic. The back-to-back defections are fueling questions about whether Google DeepMind can hold its position at the AI frontier as Anthropic and OpenAI approach IPOs. Source →
