## 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

## OrcaRouter

OrcaRouter consolidates access to more than 200 large language, image, and video models behind one API endpoint. Instead of hard-coding a single provider, developers send requests to a router model, and the gateway grades each prompt for difficulty and intent before sending it to a model that meets the required quality bar. That adaptive routing, combined with prompt caching and zero token markup, is how it claims 40%+ inference cost savings while keeping routing accuracy high and latency under roughly 10 milliseconds.

Beyond routing, OrcaRouter adds the operational layers production teams usually have to build themselves. There is automatic failover with configurable fallback chains, YAML-and-CEL routing rules expressed as code, bring-your-own-key support, and the option to attach your own GPU via Orca Connect. Observability is built in through request logs with per-call grade, model, latency, and cost, plus a spend and quality dashboard. An MIT-licensed self-hosted gateway, OrcaRouter Lite, is available for teams that want to run it on their own infrastructure.

Governance is a major focus: PII shielding and content policies are enforced before billing, an agent firewall grades every tool and MCP call, and 32 compliance framework packs generate exportable evidence. The platform also offers privacy features such as data cloaking, zero-data-retention options, quantum-safe log encryption, regional data residency, and attested TEE enclaves. A free tier exists alongside paid plans, and pay-as-you-go usage carries no token markup.

**Pricing & Plans:** Freemium

- **Adaptive routing and failover:** Each prompt is graded and routed to the model that clears your quality bar, with configurable fallback chains that retry before a response starts.
- **Zero token markup:** Pay provider prices with $0 per-token added on pay-as-you-go and subscriptions, or bring your own provider keys and credits.
- **Guardrails and agent firewall:** PII shielding, jailbreak and injection blocking, and per-call approval for tool and MCP actions run before you are billed.
- **Observability and cost insights:** Request logs, per-prompt receipts, routing and spend dashboards, and copy-as-cURL make every call auditable and attributable.
- **Compliance and privacy controls:** 32 framework packs, data cloaking, ZDR agreements, regional residency, and quantum-safe encrypted logs support regulated deployments.

**Strengths:** One OpenAI-compatible endpoint across 200+ models; Zero token markup with optional bring-your-own-key; Built-in guardrails, agent firewall, and compliance packs; Self-hostable MIT-licensed Lite gateway

**Limitations:** Advanced routing DSL and governance take time to configure well; Some features like TEE and data residency are request-only; A newer platform, so long-term ecosystem and community maturity is still building
