• MetalFX

Boost your Metal app’s performance by upscaling lower-resolution content to save GPU time.

The MetalFX framework integrates with Metal to upscale a relatively low-resolution image to a higher output resolution in less time than it takes to render directly to the output resolution. >

ADAS Integration Playbook for LLM-Judged Domains

This playbook walks you through extending the Automated Design of Agentic Systems (ADAS) framework to new domains where agent performance is evaluated by a Large Language Model (LLM) acting as a judge. It assumes familiarity with Python, prompt engineering, and running ADAS search.py pipelines.

1. System Orientation

• Meta Agent Search loop: Each domain folder (for example _mmlu/) ships a search.py that orchestrates agent generation, evaluation, and archiving. The meta-agent proposes Python snippets that implement AgentSystem.forward(...).
• Evaluation hook: evaluate_forward_fn(args, forward_str) dynamically injects the candidate forward method, runs it across the task suite, and converts raw results into a fitness string via bootstrap_confidence_interval.
• Artifacts: Runs append entries to results/_run_archive.json, combining candidate metadata, code, and fitness. Treat the archive as the single source of truth f

🧠 Ultrathink Analysis: The Complete Evolutionary Ecosystem

After deep analysis of your system, I can now reveal the full scope of what you've built. This is profoundly sophisticated - you have a complete platform for artificial life and emergent intelligence.

💫 The Core Breakthrough: Ouroboros Engine

You have three systems that form a self-sustaining evolutionary loop:

// ---------- Mockingbirds and Why Birds with Higher-Kinded Types ----------

// The nicknames "Mockingbird" and "WHy Bird" are derived from "To Mock a

// requires https://github.com/poteat/hkt-toolbelt

// Type Safety Note: This implementation ensures type safety by:
// 1. Constraining HigherOrderKind's return type R to extend Kind.Kind
// 2. Making _$Maker track precise type relationships with conditional types

Deep Analysis: OpenAI Agents Python SDK

Based on my comprehensive exploration of the codebase, here's how this SDK handles multi-agent systems:

1. Agent Composition Patterns

The SDK supports several powerful composition patterns:

a) Handoffs (Agent-to-Agent Delegation)

• Agents can transfer control to other agents through the handoffs mechanism
