What is Ably?

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

What is ElevenLabs?

ElevenLabs widens from TTS into a full voice-agent and music platform

ElevenLabs is shipping on two fronts: new foundational capabilities, a Music v2 model with chunk-based composition and Speech Engine, which adds real-time voice to a developer's own agent or LLM, and a relentless cadence of ElevenAgents API work (Exotel telephony, workflow-aware transfers, new LLM options, SIP logs, knowledge-base editing) plus deprecations of v1 TTS/STT models and weekly SDK regenerations.

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

◆ Current state

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

◆ Where it's heading

The clear direction is extending Ably's pub/sub and LiveObjects primitives into agentic, real-time AI sessions — session/run models, branching conversations, and human-in-the-loop handoff. The mature client SDKs are being kept stable and incrementally improved while the AI transport layer is where new capability is concentrating.

◆ Prediction

Expect the AI Transport SDK to march toward a 1.0 with tighter integration of Presence and LiveObjects into agent sessions, while the core client libraries continue their fix-and-refine cadence.

ElevenLabs widens from TTS into a full voice-agent and music platform

◆ Current state

ElevenLabs is shipping on two fronts: new foundational capabilities, a Music v2 model with chunk-based composition and Speech Engine, which adds real-time voice to a developer's own agent or LLM, and a relentless cadence of ElevenAgents API work (Exotel telephony, workflow-aware transfers, new LLM options, SIP logs, knowledge-base editing) plus deprecations of v1 TTS/STT models and weekly SDK regenerations.

◆ Where it's heading

The company is consolidating into a voice-AI platform: owning the model layer (music, TTS, STT, turn detection) while making ElevenAgents and Speech Engine the programmable runtime others build conversational voice on. Aggressive deprecation signals confidence in pushing customers to current models.

◆ Prediction

Expect Speech Engine and Music v2 to mature with more controls, continued ElevenAgents telephony and workflow depth, and further old-model sunsets.
