Future AGI Platform

Skill by ara.so — Daily 2026 Skills collection.

Future AGI is an open-source, end-to-end platform for evaluating, observing, and improving LLM and AI agent applications. It provides tracing (OpenTelemetry-native), 50+ evaluation metrics, multi-turn simulations, guardrails/protect, an OpenAI-compatible gateway, and prompt optimization — all in one self-hostable platform with a closed feedback loop.

    base_url=f"{os.environ['FI_BASE_URL']}/gateway/v1",
    api_key=os.environ["FI_API_KEY"],
)

# Route to different providers transparently
response = client.chat.completions.create(
    model="gpt-4o",           # Routes to OpenAI

Common Patterns

Pattern 1: Full Agent Pipeline with Tracing + Evals

import os
from fi_instrumentation import register
from traceai_openai import OpenAIInstrumentor
from fi.evals import evaluate
from fi.evals.metrics import Hallucination, ResponseRelevance
from openai import OpenAI

# Setup once
register(project_name="production-agent")
OpenAIInstrumentor().instrument()
client = OpenAI()

def answer_question(query: str, context: str) -> dict:
    """Answer a question and evaluate the response."""
    response = client.chat.completions.create(
        model="gpt-4o",
        messages=[
            {"role": "system", "content": f"Use this context: {context}"},
            {"role": "user", "content": query},
        ],
    )
    response_text = response.choices[0].message.content
    
    # Evaluate the response
    eval_result = evaluate(
        metrics=[Hallucination(), ResponseRelevance()],
        query=query,
        response=response_text,
        context=context,
    )
    
    return {
        "response": response_text,
        "evaluation": eval_result,
        "safe_to_return": eval_result.get("hallucination", {}).get("score", 1.0) < 0.5,
    }

result = answer_question(
    query="What is the boiling point of water?",
    context="Water boils at 100 degrees Celsius (212°F) at standard atmospheric pressure.",
)
print(result)

Pattern 2: RAG Pipeline with Full Observability

from fi_instrumentation import register
from traceai_langchain import LangChainInstrumentor
from langchain_openai import ChatOpenAI, OpenAIEmbeddings
from langchain_community.vectorstores import FAISS
from langchain.chains import RetrievalQA
from langchain.schema import Document

register(project_name="rag-pipeline")
LangChainInstrumentor().instrument()

# Build vector store
docs = [
    Document(page_content="Python was created by Guido van Rossum in 1991."),
    Document(page_content="JavaScript was created by Brendan Eich in 1995."),
]
embeddings = OpenAIEmbeddings()
vectorstore = FAISS.from_documents(docs, embeddings)

# Create RAG chain — automatically traced
llm = ChatOpenAI(model="gpt-4o")
qa_chain = RetrievalQA.from_chain_type(
    llm=llm,
    chain_type="stuff",
    retriever=vectorstore.as_retriever(),
)

result = qa_chain.invoke({"query": "When was Python created?"})
print(result["result"])
# Entire chain is traced: retrieval spans, LLM spans, total latency, tokens

Pattern 3: Async Agent with CrewAI

from fi_instrumentation import register
from traceai_crewai import CrewAIInstrumentor
from crewai import Agent, Task, Crew

register(project_name="crewai-demo")
CrewAIInstrumentor().instrument()

researcher = Agent(
    role="Research Analyst",
    goal="Research and summarize topics accurately",
    backstory="Expert at gathering and synthesizing information",
    verbose=True,
)

writer = Agent(
    role="Content Writer",
    goal="Write clear, engaging content based on research",
    backstory="Skilled at turning research into compelling narratives",
    verbose=True,
)

research_task = Task(
    description="Research the history of artificial intelligence",
    agent=researcher,
    expected_output="A comprehensive summary of AI history",
)

writing_task = Task(
    description="Write a blog post based on the research",
    agent=writer,
    expected_output="A 500-word blog post about AI history",
    context=[research_task],
)

crew = Crew(agents=[researcher, writer], tasks=[research_task, writing_task])
result = crew.kickoff()
# Full multi-agent trace visible in Future AGI dashboard

Pattern 4: Evaluate a Dataset and Log Results

import json
from fi.evals import batch_evaluate
from fi.evals.metrics import Hallucination, Groundedness, ResponseRelevance
from fi.datasets import Dataset

# Load your test dataset
with open("test_cases.json") as f:
    test_cases = json.load(f)
# Expected format: [{"query": ..., "response": ..., "context": ...}, ...]

# Run batch evaluation
results = batch_evaluate(
    metrics=[Hallucination(), Groundedness(), ResponseRelevance()],
    data=test_cases,
    project_name="my-agent-v2",
    dataset_name="golden-test-set-v1",  # Saves to Future AGI datasets
)

# Analyze results
hallucination_scores = [r["hallucination"]["score"] for r in results]
avg_hallucination = sum(hallucination_scores) / len(hallucination_scores)
print(f"Average hallucination rate: {avg_hallucination:.2%}")
print(f"Cases with hallucination: {sum(1 for s in hallucination_scores if s > 0.5)}/{len(results)}")

---

Troubleshooting

Traces not appearing in dashboard

# 1. Verify env vars are set
import os
assert os.environ.get("FI_API_KEY"), "FI_API_KEY not set"
assert os.environ.get("FI_BASE_URL"), "FI_BASE_URL not set — defaults to cloud"

# 2. Force flush traces (important in short-lived scripts)
from fi_instrumentation import register
provider = register(project_name="test")
# ... your code ...
provider.force_flush()  # Ensure all spans are sent before exit

# 3. Enable debug logging
import logging
logging.basicConfig(level=logging.DEBUG)
logging.getLogger("fi_instrumentation").setLevel(logging.DEBUG)

Self-hosted: Services not starting

# Check all containers are running
docker compose ps

# View logs for a specific service
docker compose logs -f backend
docker compose logs -f gateway
docker compose logs -f frontend

# Restart a specific service
docker compose restart backend

# Full reset (WARNING: destroys data)
docker compose down -v
docker compose up -d

Evaluation returning unexpected results

from fi.evals import evaluate
from fi.evals.metrics import Hallucination

# Check metric configuration
metric = Hallucination(
    model="gpt-4o",          # Specify judge model explicitly
    threshold=0.5,           # Adjust sensitivity
    verbose=True,            # Get detailed reasoning
)

result = evaluate(
    metrics=[metric],
    query="test query",
    response="test response",
    context="test context",
)
# verbose=True returns explanation field
print(result["hallucination"].get("explanation", ""))

Gateway connection issues

# Test gateway health
curl ${FI_BASE_URL}/gateway/health

# Test OpenAI-compatible endpoint
curl ${FI_BASE_URL}/gateway/v1/models \
  -H "Authorization: Bearer ${FI_API_KEY}"

# Check gateway logs
docker compose logs -f gateway

SDK version compatibility

# Check installed versions
pip show ai-evaluation fi-instrumentation traceai-openai

# Update all Future AGI packages
pip install --upgrade ai-evaluation fi-instrumentation traceai-openai traceai-langchain

# Pin to stable versions in requirements.txt
# ai-evaluation>=0.1.0
# fi-instrumentation>=0.1.0
