What is anySQL?

anySQL is an open-source SQL analytics engine for AI systems. It lets engineers query LLM responses, agent traces, and RAG pipelines with standard SQL — powered by DuckDB in-memory, persisted to SQLite, with zero configuration.

AI engineers debug with print() statements, JSON log files, and pre-built dashboards that show what the tool designer thought you'd want to see. What's missing is raw SQL over normalized AI telemetry data — specifically the cross-layer JOIN that lets you ask whether your RAG pipeline is failing at retrieval or generation.

Quick Start

# Install
pip install anysql-sdk

# Install with provider support
pip install "anysql-sdk[openai]"
pip install "anysql-sdk[anthropic]"
pip install "anysql-sdk[all]"        # OpenAI + Anthropic + LangChain

import anysql

# Initialize (in-memory by default, or pass a file path for persistence)
db = anysql.init()

# Wrap your OpenAI client — all calls are auto-logged
client = anysql.openai(openai_client)

# Wrap your Anthropic client
client = anysql.claude(anthropic_client)

# Tag pipeline runs for cost attribution
@anysql.context(feature="search", version="v2")
def run_search(query):
    ...

# Query anything with standard SQL
df = db.query("SELECT model, AVG(cost_usd) FROM llm_responses GROUP BY model")

# Or use built-in analytics methods
df = db.model_comparison()       # UC1: multi-model comparison
df = db.prompt_regressions()     # UC2: regression detection
df = db.cost_by_feature()        # UC3: cost attribution
df = db.tool_failure_rates()     # UC4: agent debugging
df = db.rag_failure_modes()      # UC5: RAG forensics

How It Works

User Code
    │
    ├── @anysql.context(feature="x")     ← Python contextvars, sync+async safe
    ├── OpenAI/Claude wrapped client      ← transparent proxy, one-line swap
    ├── AgentTracer (LangChain callback)  ← manual or callback-based
    └── RAGTracer.after_retrieval()       ← auto-detects LangChain/LlamaIndex/dict
              │
              ▼ insert()
    AnySQL engine
    ├── in-memory buffer (dict lists per table)
    ├── SQLite persistence (JSON blobs, cross-session)
    └── DuckDB (Arrow views, SQL at query time)
              │
              ▼ query()
    6 PyArrow tables as DuckDB views:
    llm_responses, eval_results, pipeline_runs,
    agent_tool_calls, agent_trace, rag_chunks

Key design decisions:

• Schema enforcement at Arrow layer — SQLite stores raw JSON, validation happens at query time
• Dot-namespace tables (llm.responses) map to flat SQL view names (llm_responses)
• Contextvars for thread-safe and async-safe tagging — no manual pass-through required

The 6 Canonical Tables

Table	Use Cases	Join Keys
llm_responses	UC1, UC2	response_id
eval_results	UC1, UC2, UC5	response_id, run_id, query_id
pipeline_runs	UC3	run_id, session_id
agent_tool_calls	UC4	session_id
agent_trace	UC4	session_id
rag_chunks	UC5	query_id ← cross-layer join key

---

The 5 Use Cases

UC	Name	Key Methods	What It Answers
UC1	Multi-Model Comparison	model_comparison(), model_by_task()	Which model performs best on my task?
UC2	Prompt Regression Detection	prompt_regressions(), eval_debt(), silent_degradation()	Did my last prompt change break something?
UC3	Cost Attribution	cost_by_feature(), cost_anomalies()	Which feature is burning my LLM budget?
UC4	Agent Debugging	tool_failure_rates(), loop_detector(), session_diff(), human_intervention_points()	Where is my agent getting stuck?
UC5	RAG Forensics	rag_failure_modes(), chunk_quality_ranking(), similarity_calibration()	Is my RAG failing at retrieval or generation?

The cross-layer join (UC5) is the killer feature — query_id threads RAG retrieval to eval results, enabling retrieval vs. generation failure classification.

Installation

From PyPI

pip install anysql-sdk

Provider extras

pip install "anysql-sdk[openai]"      # + openai>=1.0.0
pip install "anysql-sdk[anthropic]"   # + anthropic>=0.25.0
pip install "anysql-sdk[langchain]"   # + langchain>=0.2.0

CLI Usage

# Run a SQL query against a persisted database
anysql query "SELECT model, COUNT(*) FROM llm_responses GROUP BY model"

# Show table row counts and basic stats
anysql stats

# Query a specific database file
anysql query "SELECT * FROM eval_results LIMIT 10" --db ./myproject.db

Examples

Three runnable demos are included in examples/. All auto-detect missing API keys and fall back to mock mode — no downloads required.

Demo	Dataset	Models
realtime_openai_demo.py	BBC News (2004–05), 12 articles	gpt-4o, gpt-4o-mini
realtime_claude_demo.py	AG News, 15 articles	claude-sonnet-4-6, claude-haiku-4-5
realtime_combined_demo.py	Reuters R8, 20 articles	All 4 models head-to-head

# Run combined demo (works without API keys)

Adapter Usage

OpenAI

import openai
import anysql

db = anysql.init()
client = anysql.openai(openai.OpenAI())

# All calls now logged automatically
response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Summarize this article..."}]
)

Anthropic

import anthropic
import anysql

db = anysql.init()
client = anysql.claude(anthropic.Anthropic())

response = client.messages.create(
    model="claude-sonnet-4-6",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Classify this text..."}]
)

Agent Tracing

tracer = anysql.agent_tracer()

# Manual tracing
tracer.trace_tool_call(
    session_id="sess-001",
    tool_name="web_search",
    input_data={"query": "latest news"},
    output_data={"results": [...]},
    success=True,
    latency_ms=320,
)

# LangChain callback (automatic)
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(callbacks=[tracer])

RAG Tracing

rag = anysql.rag_tracer()

query_id = rag.before_retrieval(query="What is anySQL?")
chunks = retriever.get_relevant_documents(query)
rag.after_retrieval(query_id=query_id, chunks=chunks)

# Record eval result with cross-layer join key
rag.record_eval(
    query_id=query_id,
    score=0.92,
    passed=True,
    eval_type="faithfulness",
)
