Deepgram is widening language coverage while quietly replacing its diarization core.
Deepgram shipped a new batch speaker diarization architecture as an opt-in diarize_model parameter, then made it the default in the May self-hosted release. Alongside it, profanity filtering rolled out to 50+ monolingual languages and then to all multilingual models, numerals support reached Russian, Romanian, and Hebrew, and Gemini 3.1 Flash Lite replaced its preview version in the Voice Agent API.
Superhuman gives team admins a console and Enterprise a usage report that counts MCP.
Superhuman is a premium email client building a calendar, team comments and AI around its mail core. October's mobile batch added Compact Mode, swipe actions and attachment-aware AI, and the iOS app now fits iPhone Duo. The newest release adds a team admin console on all plans and an Enterprise-only Team Activity page.

Two tracks run at once. The model track is a genuine architecture replacement in diarization, moved from opt-in to default inside a week and a half, which is a fast promotion for a core speech component. The coverage track is unglamorous breadth — languages, filters, numerals — that determines whether the platform can be adopted outside English-first markets. The Voice Agent work is managed-model plumbing rather than a direction of its own.
Diarization v2 should reach streaming after landing in batch and self-hosted, since that is where the earlier architecture is weakest for live agents. Expect the language-coverage releases to continue at the same steady cadence.

The product is moving from a single-user power tool toward something a company buys and administers. Seat counts, join approvals, billing and role changes now live in one place, and Team Activity reports which members use desktop, mobile or the MCP and whether they touch AI and collaboration features. That is the reporting a buyer needs to justify renewals.
Expect more Enterprise-gated controls built on Team Activity, such as usage-based seat management or policy settings for AI and MCP access. The entries do not show pricing changes, so the timing of any upsell is unclear.
