Opal Zero

Want to use LLMs but you're not an AI engineer?
OpalZero is the AI engineer — you just write 5 lines of code.

Putting AI into your product normally means learning prompt engineering, context windows, tool-calling schemas, retries, model trade-offs, and how to wrangle messy model output into data you can actually use. That's a full-time job — an AI engineer's job.

OpalZero does that job for you. Run one container, send a plain-English intent (and, optionally, the exact shape of the answer you want), and get back clean, structured data. No prompts. No model wiring. No output parsing. You keep writing your app.

OpalZero is the AI engineer you don't have to hire.

import{OpalZeroClient}from"opal-zero";constoz=newOpalZeroClient({baseUrl: "http://localhost:8000"});forawait(consteofoz.execute("Compare the top 3 EVs under $60k"))if(e.type==="mission_complete")console.log(e.mission_state);

Five lines. Behind them, OpalZero planned the work, ran live web searches, analysed the findings, quality-checked the result, and handed back structured data.

🔭 OpalGlimpse — our first product, built on OpalZero (launching soon)

If OpalZero is the engine, OpalGlimpse is the first thing we're building with it: autonomous monitoring that watches markets, competitors, prices, or any signal on a schedule — and shows you exactly what changed, as structured diffs, not noise. Watch the world change while you sleep.

It launches as a hosted SaaS, and we deploy it once there's enough interest. Want early access?

What you don't have to do

The work of an AI engineer — handled by the kernel, so you never write it:

You'd normally have to…	OpalZero does it
Write and tune prompts for every task	The Planner generates them from your intent
Pick a model, then rewrite when you switch	Swap OpenAI / Claude / local with one env var
Wire up tools — web search, code, files, APIs	Agents call them from a built-in registry
Add retries, validation, and quality control	The Governor scores every result and re-runs the gaps
Parse freeform text into usable fields	Declare a schema; get exactly that shape back
Stand up and babysit AI infrastructure	One self-hosted container — your keys, your data

---

What it does

You send one sentence. OpalZero takes it from there:

1. Planner breaks the intent into a dependency-ordered task graph
2. Dispatcher assigns each task to a specialist agent (WebSearcher, Analyst, Coder, …)
3. Governor scores every result across five quality criteria — and injects new tasks if the bar isn't met
4. ContextBus aggregates all outputs into a typed, structured MissionState
5. Everything streams back to your app over SSE, event by event

intent ──▶ Planner ──▶ Dispatcher ──▶ Agents
│
Governor ◀── quality gate
│
ContextBus
│
your app ◀── SSE stream ◀───────┘

The result is not a chat response. It is a structured data payload — a map of named values (metrics, tables, timelines, images) that your frontend can render directly, export as CSV/Markdown/HTML, or feed into the next operation.

Five minutes to first result

1. Start the server:

With OpenAI:

docker run \
-e OPENAI_API_KEY=sk-... \
-e TAVILY_API_KEY=tvly-... \
-p 8000:8000 \
ghcr.io/albertobarnabo/opalzero-server:latest

Or fully local with Ollama (no API key required):

ollama pull llama3.1:8b # any model that supports tool calling
docker run \
-e OPALZERO_PROVIDER=ollama \
-e OPALZERO_MODEL=llama3.1:8b \
-p 8000:8000 \
ghcr.io/albertobarnabo/opalzero-server:latest

2. Install the SDK:

npm install opal-zero

3. Run a mission:

import{OpalZeroClient}from"opal-zero";constclient=newOpalZeroClient({baseUrl: "http://localhost:8000"});forawait(consteventofclient.execute("Compare the top 3 EVs under $60k")){if(event.type==="task_completed")console.log(`✅ ${event.slug}:`,event.result);if(event.type==="mission_complete")console.log("Result:",event.mission_state);}

Or with React:

import{useOpalZero}from"opal-zero/react";const{ run, status, cards, activeAgent }=useOpalZero({ client });// cards is BentoCard[] — typed, ready to render, no parsing needed

---

Bring your own schema

The promise — clean, structured data, not a wall of text — comes down to one feature: declare the shape you want, and the kernel is contractually bound to return exactly that. The Governor enforces it. No hallucinated fields, no missing keys, nothing to post-process.

forawait(consteofoz.execute("Financial brief for Apple",undefined,// model — omit for the server default{// schema — your contractprice_usd: "number",market_cap_usd: "number",competitors: "array",},)){if(e.type==="mission_complete")console.log(e.mission_state?.data_payload);}

To the kernel, every task is the same task: an intent and the shape of its answer. That's what lets you delegate any AI feature — not just the ones someone shipped a template for. Python (oz.execute(intent, schema=...)) and plain curl accept the same schema field.

Key capabilities

Capability	Description
Autonomous planning	The Planner determines the task graph from your intent — no templates, no predefined flows
Specialist agents	WebSearcher, Analyst, Coder, and custom agents implemented as WASM modules
Live quality gate	The Governor validates every agent result and expands the plan mid-run if coverage is insufficient
Structured output	Results come back as typed data (MissionState), not unstructured text
Mission refinement	Deepen any completed mission with a follow-up intent; new data merges into the existing result
Human-in-the-loop	Agents can pause and ask for clarification; your app answers and execution resumes
File context	Upload CSV, JSON, PDF, or images; agents can reference them during execution
Export	Any mission can be exported as Markdown, CSV, or HTML
Multi-provider	Run on OpenAI, Anthropic Claude, Ollama local models, or any OpenAI-compatible endpoint (Groq, Mistral, Together…)
Self-hosted	Runs as a single Docker container; your data never leaves your infrastructure

The agent tool belt

Agents have access to a registry of composable tools, compiled to WASM:

Tool	What it does
web_search	Real-time web search via Tavily
fetch_page	Fetch and parse any URL
rss_reader	Read RSS/Atom feeds
vision	Analyse images (via OpenAI Vision)
python_interpreter	Execute sandboxed Python
calculator	Evaluate mathematical expressions
read_csv	Parse and summarise CSV files
sqlite_query	Run SQL against an in-memory SQLite DB
extract_pdf_text	Extract text from uploaded PDFs
http_request	Make arbitrary HTTP calls
diff	Compare two text blocks
send_email	Send SMTP email
memory / memory_persist	Short-term and persistent agent memory
get_price_history	Stock price history (Alpha Vantage)
get_income_statement	Company financials (Alpha Vantage)
get_news_sentiment	Market news sentiment (Alpha Vantage)
get_company_overview	Company overview (Alpha Vantage)
generate_document	Produce structured document output
build_dynamic_ui	Emit layout hints and design tokens for the frontend
finalize_mission_state	Write the final typed result payload
feedback	Pause execution and request human input

New tools are added as WASM modules — no server recompilation needed.

Provider backends

OpalZero supports multiple AI backends. Switch with OPALZERO_PROVIDER — no code changes required.

OpenAI (default)

OPALZERO_PROVIDER=openai OPALZERO_MODEL=gpt-4o-mini OPENAI_API_KEY=sk-... cargo run --bin opalzero-server

Ollama — fully local, no API key

ollama pull llama3.1:8b
OPALZERO_PROVIDER=ollama OPALZERO_MODEL=llama3.1:8b cargo run --bin opalzero-server

OpalZero requires a model that supports tool calling. Recommended:

Model	Size	Notes
llama3.1:8b	4.7 GB	Best balance of speed and quality
mistral-nemo	7.1 GB	Strong reasoning, great for Analyst tasks
qwen2.5:7b	4.7 GB	Fast, reliable tool-call support

Anthropic Claude

OPALZERO_PROVIDER=claude OPALZERO_MODEL=claude-sonnet-4-5 ANTHROPIC_API_KEY=sk-ant-... cargo run --bin opalzero-server

Haiku is automatically used for cheaper sub-tasks while your selected model handles planning and analysis.

Any OpenAI-compatible endpoint (Groq, Together, Mistral, LM Studio…)

OPALZERO_PROVIDER=compatible \
OPALZERO_BASE_URL=https://api.groq.com/openai/v1 \
OPALZERO_MODEL=llama-3.3-70b-versatile \
cargo run --bin opalzero-server

Self-hosting

OpalZero is designed to run on your own infrastructure. The server is a single Rust binary wrapped in a minimal Docker image — no external database, no telemetry, no callbacks home. Missions and uploads persist to local volumes you control.
