Antigravity CodeMode: Gemini 4.0 Argon & Gemini 3.8 Flash

Antigravity CodeMode: Gemini 4.0 Argon + Gemini 3.8 Flash Architecture

Antigravity introduces an enterprise dual-engine execution harness built specifically for complex agentic engineering tasks. By decoupling high-order architectural planning from low-latency programmatic batch code execution, Antigravity eliminates conversational turn-churn and guarantees deterministic multi-file operations.

1. Dual-Tier Cognitive Architecture

• Gemini 4.0 Argon (Lead Architect): Anchors deep reasoning, repository-scale context synthesis, architectural design, intent validation, and safety verification.
• Gemini 3.8 Flash (High CodeMode Worker): Specialized high-speed worker executing structured OMP (One-Turn Programmatic Batch Execution). Dispatched to inspect, modify, test, and verify files in <= 2 tool turns.

2. Programmatic Tool Execution (OMP Pattern)

Traditional agents consume 10 to 30 conversational turns running sequential read/edit/bash steps. In Antigravity, Gemini 3.8 Flash generates consolidated Python scripts via the satrap_cm SDK, executing inspection, transformation, testing, and git operations in a single synchronous turn.

# Antigravity Programmatic Batch Execution Pattern
import satrap_cm as cm

# Step 1: Batch inspect & patch
patch_summary = cm.replace_in_files(
    directory="/workspace/repo",
    pattern="legacy_handler",
    replacement="argon_flash_handler"
)

# Step 2: Immediate verification
res = cm.run_cmd("pytest tests/ -q && git diff --stat")
print(f"Verified {len(patch_summary)} changes. Status: {res.exit_code}")

3. Strict Model Governance

Antigravity adheres to zero-hallucination model standards. The entire runtime environment, SDK bindings, and agent rules are locked to Gemini 4.0 Argon and Gemini 3.8 Flash.
