## 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

## Scorecard

Scorecard describes itself as the simulation platform for agent self-improvement. Its premise is that you cannot QA your way to the frontier: as agents grow more complex, every change has to be tested against exponentially more scenarios, and reviewing production logs by hand does not scale. The platform replaces that backlog with a fast feedback loop by running your agent through thousands of realistic scenarios and returning scored results in minutes.

The product spans the full agent lifecycle. A simulation lab lets teams run structured experiments and try ideas quickly. A prompt space handles creation, testing and versioning so the best-performing prompts are stored with a history and shared as a single source of truth. A validated metric library provides industry benchmarks that can be customized or extended with custom metrics, which the company frames as helping teams avoid metrics they cannot trust.

Beyond testing, Scorecard also covers deployment: agents can be managed and shipped to production without touching an IDE, and real-world usage issues can be identified and addressed as they appear. The company targets teams building reliable AI agents and promotes the idea that continuous, simulation-driven evaluation is how frontier labs build best-in-class agents.

**Pricing & Plans:** Scorecard uses a freemium-to-enterprise model. The site does not publish concrete price points; instead it offers a free or low-commitment way to start alongside paid and enterprise tiers, with a book-a-demo flow and contact-for-pricing for teams. Exact plan details should be confirmed directly with the vendor.

- **Fast feedback loop:** Run your agent through thousands of realistic scenarios and get scored feedback in minutes instead of waiting weeks for expert log review.
- **Experiment and simulation lab:** Create structured experiments and test ideas quickly in an AI laboratory before committing to a change.
- **Trustworthy metric library:** Start from a validated metric library of industry benchmarks, customize proven metrics, or build your own to track what matters.
- **Prompt versioning and storage:** Create, test and track your best-performing prompts in one place, keeping a history and a single source of truth for the team.
- **Production deployment:** Manage and deploy agents to production without touching an IDE, and identify real-world usage issues as they surface.

**Strengths:** Feedback in minutes rather than weeks of manual log review; Validated metric library with industry benchmarks you can customize; Prompt versioning keeps a history and a single source of truth; Covers the full lifecycle: experiment, evaluate, then deploy

**Limitations:** No public self-serve pricing shown — enterprise and team plans require a demo; Value depends on being able to define realistic scenarios for your agent domain; Scenario-based testing adds setup work before the fast feedback loop pays off; Small teams with a single simple prompt may not need a dedicated platform
