What is ElevenLabs?

ElevenLabs is turning voice agents into versioned software, with weekly API surface to prove it.

The changelog is dominated by ElevenAgents, shipped as dense weekly API digests rather than feature posts. Agents now have branches, merges, rebases and version filters, plus procedures that compile into workflows, knowledge-base crawl jobs and per-agent sentiment analysis. Alongside that, the core model lines keep advancing: Music v2, Speech Engine, and now Dubbing v2 through the API.

What is SigNoz?

SigNoz makes LLM traces readable with a conversation-style Thread view.

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

ElevenLabs is turning voice agents into versioned software, with weekly API surface to prove it.

◆ Current state

The changelog is dominated by ElevenAgents, shipped as dense weekly API digests rather than feature posts. Agents now have branches, merges, rebases and version filters, plus procedures that compile into workflows, knowledge-base crawl jobs and per-agent sentiment analysis. Alongside that, the core model lines keep advancing: Music v2, Speech Engine, and now Dubbing v2 through the API.

◆ Where it's heading

Two arcs run in parallel. The agent platform is acquiring the mechanics of source control, which points at teams operating many agent versions in production rather than one hand-tuned assistant. The model lines are being rebuilt one at a time and exposed API-first, with older v1 models given explicit removal dates. Dubbing is the newest line to make that jump.

◆ Prediction

The v1 deprecation pattern suggests dubbing_v1 gets a removal date next, and the branch tooling looks close to gaining an approval or promotion step given merge previews already exist.

5.0

SigNoz makes LLM traces readable with a conversation-style Thread view.

◆ Current state

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

◆ Where it's heading

SigNoz is moving into LLM observability from both sides: August's plugin put it inside AI coding agents, and the Thread view now makes it a place to debug AI apps. Underneath, the alerting API keeps migrating on fixed, repeatedly announced dates. Alert channels into incident tools fill out the operational side.

◆ Prediction

Expect more AI-specific views on top of the Thread view, such as token or cost breakdowns per conversation, and the v1 rules removal to ship on November 11 as announced.
