What is Telnyx?

Telnyx is racing to be the voice-AI layer for autonomous agents, model by model

Telnyx's release cadence is dominated by its Inference and Voice AI stack. Recent notes are a near-weekly drumbeat of new open-weight LLMs (GLM-5.2, Minimax M3, Kimi K2.6) on Telnyx-owned GPUs, plus STT/TTS providers (Inworld, Soniox, Deepgram, Rime) and orchestration features like Conversation Workflows. The telecom substrate is now a delivery vehicle for AI assistants.

What is Superhuman?

Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.

Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

Telnyx is racing to be the voice-AI layer for autonomous agents, model by model

◆ Current state

Telnyx's release cadence is dominated by its Inference and Voice AI stack. Recent notes are a near-weekly drumbeat of new open-weight LLMs (GLM-5.2, Minimax M3, Kimi K2.6) on Telnyx-owned GPUs, plus STT/TTS providers (Inworld, Soniox, Deepgram, Rime) and orchestration features like Conversation Workflows. The telecom substrate is now a delivery vehicle for AI assistants.

◆ Where it's heading

The platform is layering a full conversational-AI pipeline on top of its network: owned inference infrastructure, swappable best-of-breed speech models, multi-step workflow design, and persistent conversation memory. The newest move — letting AI agents self-provision accounts with their own inbox — points toward agents, not humans, as a customer class.

◆ Prediction

Expect the model menu to keep expanding as new open-weight releases land, and the agent-as-customer thread to deepen: more self-service, programmatic onboarding and memory/RAG features that let autonomous agents run end-to-end voice workflows on Telnyx without a human in the loop.

S6.3

Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.

◆ Current state

Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

◆ Where it's heading

Superhuman is positioning itself as the email client AI agents operate, not just one humans use — its MCP, Draft Sync with Gmail and Outlook, and now a Codex plugin all point the same way. In parallel it keeps sharpening Split Inbox (reorder, hide-empty, a Reminders split) and mobile flow. The bet is agent-operability plus opinionated triage as the wedge against Gmail and Outlook.

◆ Prediction

Expect more agent surface — additional MCP hosts and agent-drivable actions — alongside continued Split Inbox personalization. The entries point to agentic email as the primary investment line.
