## Arize AI

Arize is an AI engineering platform built for teams that run generative AI in production. It is split into two products: Arize AX, a managed environment for agent observability, evaluation, and experimentation, and Phoenix, an open-source tracing and evaluation library that teams can self-host when they need full data control. Both rely on OpenInference, the open-source semantic convention for generative AI tracing that the Arize team founded and that is built on OpenTelemetry.

The workflow follows three questions. Observe answers what an agent actually did by capturing every span, trace, and session; Evaluate answers whether quality is improving or regressing using span-level, trace-level, and session-level evals; Learn answers whether a proposed change will help by letting teams test prompts and harnesses before rollout. A datastore for GenAI traces (ADB) keeps data in open formats that connect to warehouses such as BigQuery, Databricks, and Snowflake, and an in-app AI engineering agent named Alyx surfaces issues and drafts review-ready fixes.

The platform integrates with dozens of models, frameworks, and tools, including OpenAI, Anthropic, Google, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and DSPy. Arize publishes compliance certifications including SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, and GDPR, and supports cloud, hybrid, and self-hosted deployment.

**Pricing & Plans:** Arize uses a paid model with a free entry point: teams can start free or book a demo, while enterprise-scale usage, deployment options, and support are quoted through a contact-sales process. The open-source Phoenix project is free to self-host.

- **End-to-end tracing:** Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
- **Scalable evaluation framework:** Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
- **Alyx AI engineering agent:** An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
- **Phoenix open-source toolkit:** Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
- **Warehouse-native trace storage:** ADB stores traces in open formats that connect natively to BigQuery, Databricks, or Snowflake for joint analytics with business data.

**Strengths:** Covers the full loop of observe, evaluate, and improve rather than stopping at dashboards; Backed by OpenInference and OpenTelemetry standards, limiting vendor lock-in on trace formats; Strong enterprise posture with SOC 2, ISO 27001, HIPAA, and GDPR coverage plus self-hosting options; Integrates with a very wide set of models, frameworks, and agent SDKs

**Limitations:** Self-serve pricing is not published, so cost requires a sales conversation; The breadth of features can be overwhelming for small teams shipping their first LLM feature; Full value depends on disciplined instrumentation across the whole application

## Hex

Hex starts from a simple observation: dashboards tell you what happened, but they rarely answer the follow-up question. Its core is the Hex Agent, a conversational interface that plans a query, reasons over your organisation's context and returns an answer with the charts, tables and code that produced it. Because every answer is grounded in a semantic model and the underlying warehouse tables, users can inspect the SQL, check assumptions and trust the number before acting on it. The agent is reachable from the web workspace, from Slack, and from developer tools such as Claude and Codex via CLI and integrations.
Underneath the conversational layer sits a genuine notebook and app-building environment. Analysts write SQL, Python and R in the same project, chain cells into reproducible pipelines, and then turn selected cells into polished, parameterised data apps and dashboards that stakeholders can interact with. Hex 4.0 pushes this further with generative dashboards, AI app building and a Context Engine that keeps the company's definitions, metrics and semantics in one place. A Context Studio surfaces where the agent lacked grounding, and an Evals framework lets teams run graded test suites against the agent to measure accuracy over time.
That governance angle is what separates Hex from raw chat-with-your-data tools. Instead of an unsearchable answer in a side panel, you get a shareable, versionable artefact with lineage, plus a feedback loop that compounds context quality. It is used by data teams at a wide range of companies for self-serve exploration, executive reporting, embedded dashboards and operational analytics, with free, paid and enterprise tiers covering individuals through to regulated organisations needing SSO and advanced security.

**Pricing & Plans:** Freemium with a free tier to get started, paid plans for growing teams, and enterprise pricing (quoted on request) that adds governance, SSO and advanced security. A free trial is available for paid tiers.

- **Conversational Hex Agent:** Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
- **Notebooks and app builder:** Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
- **Context Engine and Context Studio:** Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
- **Evals for agent accuracy:** Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.
- **Generative dashboards and governance:** Produce dashboards from natural language, embed them where teams work, and manage access with enterprise-grade permissions and security.

**Strengths:** Unifies exploration, notebooks, dashboards and app building so teams stop paying for four overlapping tools; Answers are grounded in a semantic model and warehouse tables, and stay inspectable rather than opaque; Slack, CLI and developer-tool integrations meet users where they already work; Context Studio and Evals turn context quality into something measurable and improvable

**Limitations:** The full value depends on having a reasonably well-modelled warehouse, so it is heavier to adopt than a simple chat tool; The notebook-plus-agent surface is feature-rich enough to need onboarding for non-technical users; Governance and advanced security features are reserved for higher-priced and enterprise plans
