## 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

## Semafind

Semafind works with organisations that face problems too specific to be solved by off-the-shelf software. The firm positions itself between academic research and applied engineering: it helps clients explore whether a novel algorithm or model can create a competitive edge, builds a working prototype, then integrates that technology into existing infrastructure with training and ongoing support. Its stated process runs through ideation, prototyping and integration, each stage aimed at reducing the risk of research-heavy projects.

The consultancy publishes a portfolio of applied projects that show the range of work it takes on, including a visual spare-part identification system for engineering maintenance, semantic CV matching that recommends roles from resumes and job descriptions, AI networking recommendations for events, behavioural anomaly detection for early disease identification in animals, a reverse dictionary for company terminology, and personalised e-commerce product recommendations.

Semafind also productises some of this research. SemaReader focuses on semantic reading and automatic knowledge-graph creation from documents, while SemaDB is its vector database offering for similarity search. Knotes is an additional knowledge tool. The company is a UK-registered limited company and invites prospective clients to a free initial consultation. Because engagements are scoped per project, pricing is quoted on contact rather than published as fixed public tiers.

**Pricing & Plans:** Pricing is quote-based: Semafind offers a free initial consultation and scopes consulting engagements per project. Its software products such as SemaReader and SemaDB have their own plans — check the official site for current figures.

- **Custom AI & ML engineering:** Bespoke algorithms and models built for problems that generic tools cannot solve, from computer vision to recommendation systems.
- **Research-to-production pipeline:** A structured ideation, prototype and integration process designed to de-risk research-heavy projects before full rollout.
- **Semantic knowledge tooling:** Products including SemaReader for semantic reading and knowledge-graph creation, and SemaDB, a vector database for similarity search.
- **Data science consulting:** Hands-on data analysis, anomaly detection and predictive modelling engagements shaped around specific business goals.
- **Training and ongoing support:** Integration includes team training and continued support so new technology is adopted rather than shelved.

**Strengths:** Genuine research depth rather than template implementation; Clearly documented portfolio of applied projects across industries; Combines consulting with owned products such as SemaReader and SemaDB; Free initial consultation lowers the barrier to starting a conversation

**Limitations:** No published price list, so budgeting requires a sales conversation; Project-based engagements may not suit very small, low-budget teams; Product documentation for SemaReader and SemaDB is comparatively light
