Sperimentazione con Evoluzione Sintetica Diretta
Quando la teoria incontra la realtà e il codice inizia a evolversi Inspired by thinking about extensions to mostlylucid.mockllmapi and material for the (never to be released but I like to think about it 😜) sci-fi novel "Michael" about emergent AI
**Nota:**Nota:
E' anche profondamente sperimentale, un po' pazzo, e decisamente "codificato." Sei stato avvisato.
Dalla teoria alla pratica:
In realta' l'ho costruita io.
Dopo sei parti di teorizzazione sull'intelligenza emergente, i sistemi multi-agent, il consenso globale e la cognizione planetaria, ho avuto una realizzazione:
Stavo procrastinando.**E' facile speculare sulle corporazioni sintetiche e sull'evoluzione dell'intelligenza.**E' piu' difficile costruirlo.
Cosi' ho smesso di parlare e ho iniziato a programmare.
Quello che è emerso è qualcosa che sto chiamando*Evoluzione sintetica diretta (DSE)*Un flusso di lavoro auto-assemblante e auto-ottimizzante utilizzando un sistema dinamico multi-livello e multi-agente LLM-powered.
O qualcosa del genere! (Guarda, me lo sto inventando mentre vado.)Il passo dell'ascensore: E se invece di generare codice una volta e sperando che funzioni, abbiamo creato un sistema in cui il codicecontinua evoluzione
attraverso la pianificazione, l'esecuzione, la valutazione e la mutazione?
E se potessimo insegnare a un sistema ad imparare dai suoi errori, riutilizzare modelli di successo e diventare più intelligenti nel tempo?Allarme spoiler:. In realta' funziona.*Ed e' strano.*E affascinante.
Immergiamoci.
You: "Write me a function that does X"
LLM: "Here's some code! [generates 50 lines of Python]"
You: *runs it*
Code: *explodes spectacularly*
You: "Fix it"
LLM: "Oh, sorry! Here's a new version!"
You: *runs it*
Code: *different explosion*
DI nuovo: Questo è un esperimento non è così stabile e non affatto veloce.
Ma fa quello che dice sul treno,
Davvero.ora
fare tutte le operazioni solo non bene ancora.
Il problema di cui non stiamo parlando
Ecco come funziona oggi la maggior parte della generazione di codice basata su LLM:
Le questioni sono fondamentali:
Generazione con un colpo solo
- Nessuna iterazione, nessuna raffinatezza, nessuna seconda possibilita'.
Senza memoria
Nessun feedback di qualità
[1. PLAN] → [2. GENERATE] → [3. EXECUTE] → [4. EVALUATE] → [5. EVOLVE]

Approccio tradizionale (prone all'allucinazione):
# Traditional similarity: might give false positives
Task 1: "generate fibonacci sequence"
Task 2: "generate fibonacci backwards"
Similarity: 77% ← High, but these need DIFFERENT code!
# Semantic classification
Triage LLM analyzes both tasks:
SAME → Reuse as-is (just typos/wording differences)
RELATED → Use as template, modify (same domain, different variation)
DIFFERENT → Generate from scratch (completely different problem)
Result: "RELATED - same core algorithm, reversed output"
Action: Load fibonacci code as template, modify to reverse
Approccio DSE:
RAG Memoria: Imparare dal passato
(velocità, costo, qualità, latenza)
# Original (stored in RAG):
def fibonacci_sequence(n):
if n <= 0:
return []
elif n == 1:
return [0]
sequence = [0, 1]
for i in range(2, n):
sequence.append(sequence[i-1] + sequence[i-2])
return sequence
# New request: "fibonacci backwards"
# DSE finds original, classifies as RELATED
# Generates modification spec: "Return reversed sequence"
# Modified version:

return []
elif n == 1:

Risultato
Level 1 (Workflow):
"Build a REST API"
↓
Level 2 (Nodeplans):
├─ Design API schema
├─ Implement authentication
├─ Create CRUD endpoints
├─ Add error handling
└─ Write integration tests
↓
Level 3 (Functions):
Each nodeplan breaks into individual functions
: Più veloce, più affidabile, riutilizza il codice testato
Questo riutilizzo accelera notevolmente la generazione e migliora l'affidabilità.

Evoluzione adversale
Meta-evoluzione
Sistema che evolve le proprie strategie evolutiveApprendimento collaborativo- Casi multipli di DSE che condividono le scoperte
Lezioni imparateDopo aver costruito questa cosa, ecco cosa mi ha sorpreso:
**1.**Questioni di specializzazione
**Utilizzare diversi modelli per diverse attività (overseer vs generatore vs valutatore) non era solo bello è stato essenziale.**Cercando di utilizzare un modello per tutto ha prodotto risultati notevolmente peggiori.
**2.**La memoria è tutto
La memoria RAG non è una caratteristica, è LA funzione.
Senza di esso, stai solo generando codice in un loop.Con esso, il sistema in realtà impara e migliora.
3.
4.
Evolution funziona effettivamenteOnestamente non mi aspettavo che l'auto-evoluzione producesse un codice migliore della generazione iniziale.
Coerentemente.
**E' pazzesco.**5.
Composti della latenza Stranamente
**All'inizio più chiamate LLM sembrano lente, ma mentre la memoria RAG si riempie, si colpisce più spesso soluzioni cache, e l'intero sistema accelera.**E' contro-intuitivo ma osservabile.
Provalo da solo.
**L'intera cosa è open source ed è in esecuzione localmente su Ollama:**Attenzione:
Questo e' un codice sperimentale.
**Non e' pronto per la produzione.**Non e' nemmeno pronto per il "buon codice."
Ma è un esperimento affascinante su ciò che è possibile quando si combinano algoritmi evolutivi con sistemi multi-agent LLM.
Che cosa significa questo in realtà
Facciamo un passo indietro dai dettagli tecnici e facciamo la domanda scomoda:
Cos'abbiamo costruito qui?
In superficie, e' un sistema di generazione di codici.
Chiedi una funzione, ne genera una, la immagazzina e la riutilizza più tardi.
Ma non e' proprio quello che sta succedendo.
Quello che sta succedendo e'
Non metaforicamente, ma letteralmente.
What Works ✓
What's Rough ✗
What's Just Weird 🤔
Parte 5:
Pressione evolutiva → Cultura e tradizioni
Il sistema sviluppa "preferenze" alcuni strumenti per determinati compiti, determinati modelli per determinati problemi.
Imparato.
Parte 6:
Perché non a livello planetario?
Sto dicendo che il gradiente è continuo da "evolvere una funzione" a "evolvere una civiltà."
Ed e'... inquietante.
Che cosa funziona realmente (Let's Be Onest)
