AILANG: AI-First Programming Language

Makes AI-generated code cheaper to debug, replay, and fix. Built on 12 design axioms for deterministic, traceable execution.

Why AILANG?

AI coding agents write code fast, but debugging is slow.

  • Deterministic Replay: Same input, same output—replay any execution for debugging
  • Effect Boundaries: Side effects explicit in types, preventing hallucinated operations
  • AI Agent Integration: Works with Claude Code, Gemini CLI, and other coding agents
  • 66 Examples: Comprehensive examples and interactive playground

Performance Benchmarks

AILANG vs Python Performance Comparison

AILANG demonstrates competitive performance across major LLM models, with Claude Haiku 4.5 showing only a 23.8% accuracy gap compared to Python

Deterministic Execution

Every execution is replayable. Debug AI-generated code by stepping through exactly what happened.

Capability Security

Permissions are statically visible. AI can't generate code that exceeds its authority.

Structured Traces

Execution logs organized by effect type for clear visibility into what operations occurred.

Sunholo Python Library

A comprehensive Python framework for building production-grade AI applications, used by developers worldwide.

pip install sunholo

from sunholo import create_agent

# Build production-ready AI agents
agent = create_agent(
    name="assistant",
    llm="gemini-2.5-pro",
    tools=["web_search", "document_qa"]
)

response = agent.run("Analyze Q4 reports")

Simple, intuitive API for complex AI workflows
