What is Arize AI?

Arize doubles down on agent observability: managed agents land in AX, traces flow to Databricks

Arize is building out its AI-observability platform around agents. The headline product move is Arize AX adding managed agents, full-agent experimentation, multimodal support, and Harness-as-a-Judge. It also connected Data Fabric to Databricks so teams can govern agent traces in their own Unity Catalog. The rest of the feed is research and community content.

What is Gladia?

Gladia ships a new flagship speech-to-text model and edges into the meeting-bot stack.

Gladia sells speech-to-text as an API, competing with Deepgram and AssemblyAI. Its recent work centers on model accuracy — the new Solaria-3 model and an open benchmark — alongside developer ergonomics (an official async SDK, a multilingual normalization library) and enterprise trust signals. A new Attendee integration pushes it toward live meeting transcription.

Arize doubles down on agent observability: managed agents land in AX, traces flow to Databricks

◆ Current state

Arize is building out its AI-observability platform around agents. The headline product move is Arize AX adding managed agents, full-agent experimentation, multimodal support, and Harness-as-a-Judge. It also connected Data Fabric to Databricks so teams can govern agent traces in their own Unity Catalog. The rest of the feed is research and community content.

◆ Where it's heading

Arize positions as the place to observe, evaluate, and improve production agents end to end, pairing platform features with a research drumbeat (trace analysis, evals over fine-tuning, OpenInference standards) that frames its worldview. The Phoenix open-source project remains the community on-ramp.

◆ Prediction

Expect more agent-lifecycle features in AX (evaluation, experimentation, judging) plus continued investment in OpenInference as a shared trace standard to entrench its observability position.

Gladia ships a new flagship speech-to-text model and edges into the meeting-bot stack.

◆ Current state

Gladia sells speech-to-text as an API, competing with Deepgram and AssemblyAI. Its recent work centers on model accuracy — the new Solaria-3 model and an open benchmark — alongside developer ergonomics (an official async SDK, a multilingual normalization library) and enterprise trust signals. A new Attendee integration pushes it toward live meeting transcription.

◆ Where it's heading

Two threads run through the changelog: advancing the core STT model on real-world, multilingual audio, and positioning Gladia inside the meeting-assistant ecosystem it mapped publicly in May. The Attendee integration, multilingual normalization, and async SDK all lower the friction of wiring Gladia into voice and meeting products.

◆ Prediction

Expect continued Solaria model iteration and more meeting-platform integrations — or first-party bot tooling — as Gladia leans into the meeting-transcription use case it keeps signaling.
