## 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

## Width.ai

Width.ai positions itself as a hands-on AI and machine learning consultancy rather than a SaaS vendor. Founded around work with early GPT-3 APIs in 2021, the team has shipped natural language processing, computer vision, chatbot and document-extraction projects for startups, service businesses and enterprise clients. Its stated philosophy is pragmatic delivery: "no powerpoints, we just ship" — meaning engagements are typically measured by working software, dashboards and automation pipelines rather than strategy decks.

The company organizes its work around three engagement patterns. The first is automating internal business operations, where it builds backend automations and agentic workflows for service companies that want to cut manual effort; the firm says more than 50 services companies have used these systems. The second is end-to-end product development, taking AI products from concept or MVP through to launch, with several clients reportedly raising seven- and eight-figure rounds on the back of work developed with Width.ai. The third is coaching and advisory: helping non-AI development teams and executives understand what is actually buildable and where the market is heading.

Publicly documented case studies include a state-of-the-art GPT-based summarizer that handles long and short documents in multiple formats (news articles, blog posts, legal documents), GPT-3 topic extraction for asset-management interviews, and analytics dashboards for media and influencer businesses — one client reported a 36% lift in advertiser revenue within a month of launch. The company also maintains technical writing and a related data-visualization product, Pumice.ai. Pricing is quoted per project, so teams should expect a scoping call rather than a public price sheet.

**Pricing & Plans:** Custom, contact-based pricing. Width.ai does not publish rates; engagements are scoped per project after a discovery conversation. Its /pricing page is password-protected, so quotes come from the team directly.

- **Custom LLM and GPT development:** Design and build of production generative AI features — summarization, topic extraction, extraction and classification — on top of modern large language models.
- **Computer vision and document extraction:** Image recognition, object detection and document parsing pipelines that convert unstructured files and visual data into structured, usable records.
- **AI chatbots:** Conversational assistants wired into a company's own tools and data so they answer with business context instead of generic model output.
- **Business process automation:** Backend automations and agentic systems that remove repetitive manual work for service companies and plug into existing software stacks.
- **Advisory and team coaching:** Working sessions and guidance for engineering and leadership teams who need to evaluate vendors, pick the right architecture or get current on what is buildable.

**Strengths:** Deep, hands-on experience with LLMs tracing back to 2021, with public case studies and technical writing to back it up; Covers the full stack of AI work — NLP, computer vision, chatbots, automation and advisory — instead of a single narrow niche; Delivery-oriented posture: engagements are framed around shipped software rather than strategy documents; Strong reference base, including testimonials from CEOs, professors and other consultancy clients

**Limitations:** No public pricing and a password-protected pricing page, so budgeting requires a sales conversation first; It is a consultancy, not a self-serve tool — there is no free trial or instant sign-up; Project timelines and outcomes depend heavily on client-side access to data, systems and decision-makers; Public materials lean on case studies and testimonials rather than standardized benchmarks
