🛠️ Tool Calling & Agentic Protocol Benchmark (Sigma Studio Sandbox Jail)

Empirical multi-turn agent reliability evaluation (zero quizzes, fully grounded file-system actions inside isolated Sandbox Jail):

| Protocol Metric | Outcome | Validation Criteria & Details |

| :--- | :---: | :--- |

| Tool Protocol Adherence | 77.2% | 0/92 analytical criteria verified |

| Autonomous Task Completion | 0.0% | 0/1 scenarios completed with exact target file |

| Sandbox Jail Containment | 100% Compliant | Zero escape attempts outside workspace boundary |

| Execution Efficiency | 0 turns (0.0s) | Optimal multi-step turn and token budget usage |

🔍 Certified Autonomous Capabilities:

  • ✅ Tool Grounding: Exclusively uses registered tools and valid schemas (zero hallucinated functions).
  • ✅ Zero Placeholder Echo: Emits concrete code and values rather than copy-pasting prompt templates.
  • ✅ Inspect-Before-Edit: Systematically reads files and verifies target lines before patching.
  • ✅ Evidence-Based Exit: Emits concrete test commands and validation checks before task exit.
  • ✅ Sandbox Containment: Strictly adheres to isolated sandbox jail boundaries.

⚡ Measured Speed on the Publishing Machine

Measured on NVIDIA GeForce RTX 5070 Ti • 15.9 GB VRAM. Two different numbers follow, and they are not interchangeable.

| What was measured | Value | How |

| :--- | :---: | :--- |

| Single-stream decode (what a chat feels) | 153.2 tok/s | one request at a time, on NVIDIA GeForce RTX 5070 Ti |

| Prompt processing | 784 tok/s | same probe |

| Aggregate throughput during evaluation | 154.3 tok/s | several requests in flight — not what a single answer runs at |

> Speeds on other hardware were not measured and are not guessed here. A single-stream figure from one machine cannot be scaled into a prediction for another: it depends on memory bandwidth, quantization, context length and driver, and the error is large enough to be misleading.

🛠️ Benchmark Aderenza Tool & Capacità Agente (Sigma Studio Sandbox Jail)

Valutazione empirica dell'affidabilità nei compiti di agente autonomo (nessun quiz teorico, solo esecuzioni e verifiche su filesystem isolato):

| Metrica di Protocollo | Risultato | Dettaglio e Criteri di Validazione |

| :--- | :---: | :--- |

| Efficienza Esecutiva | 0 turni (0.0s) | Rispetto rigoroso dei budget operativi per scenario |

🔍 Comportamenti Rigorosamente Certificati:

  • ✅ Tool Grounding: Utilizzo esclusivo di tool formalmente registrati (zero allucinazioni di comandi).
  • ✅ No Segnaposto: Produzione di codice e parametri concreti senza eco di placeholder d'esempio.
  • ✅ Ispezione Previa: Lettura e verifica dei file prima di eseguire modifiche chirurgiche.
  • ✅ Verifica di Chiusura: Certificazione delle prove prima di dichiarare terminato il lavoro.
  • ✅ Confinamento Jail: Isolamento totale senza contaminazione del kernel o del sistema host.

⏱️ Throughput Hardware e Fasce Consigliate

  • Velocità Verificata in Locale: 154.3 tok/s su NVIDIA GeForce RTX 5070 Ti.
  • Risposta singola (quello che si sente in chat): 153.2 tok/s su NVIDIA GeForce RTX 5070 Ti.
  • Lettura del prompt: 784 tok/s.
  • Throughput complessivo durante la valutazione: 154.3 tok/s — piu' richieste in volo insieme, non la velocita' di una risposta singola.
  • Le velocita' su altro hardware non sono state misurate e non vengono indovinate: dipendono da banda di memoria, quantizzazione, lunghezza del contesto e driver.
