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 Ollama?

Ollama v0.40.16 adds the 65B Ripple Preview coding model and cuts Qwen3.8 Flash memory on Macs.

Ollama keeps a weekly rhythm of model additions plus agent-host plumbing. v0.40.16 adds Ripple Preview, a 65B dense model for agentic coding, cuts Qwen3.8 Flash Next memory use on Apple silicon by about 27 GiB, makes `ollama launch claude` always route Claude Code to the selected model, and stops /v1/responses from silently truncating. A v0.40.17 candidate has started with an MLX version bump.

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.

Ollama v0.40.16 adds the 65B Ripple Preview coding model and cuts Qwen3.8 Flash memory on Macs.

◆ Current state

Ollama keeps a weekly rhythm of model additions plus agent-host plumbing. v0.40.16 adds Ripple Preview, a 65B dense model for agentic coding, cuts Qwen3.8 Flash Next memory use on Apple silicon by about 27 GiB, makes `ollama launch claude` always route Claude Code to the selected model, and stops /v1/responses from silently truncating. A v0.40.17 candidate has started with an MLX version bump.

◆ Where it's heading

Each release pairs a new open coding model with fixes for how Ollama behaves behind other agents, from Claude Code routing to OpenAI-compatible endpoints. The MLX runner keeps getting attention, which points at Apple silicon as a priority platform.

◆ Prediction

Expect v0.40.17 within a week with another model addition and more MLX runner work.
