StrataRealLowVRAM v0.1.35 — Extreme Low-VRAM & Mobile GPU Edition

Empirically verified on NVIDIA GeForce RTX 3050 Laptop (4 GB GDDR6) + AMD Ryzen 5 5500U + 32 GB DDR4 on Windows 11.
Full 65,536 context (--max-context 65536) with zero memory eviction or WDDM driver clamps.


⚡ Highlights of This Release

This release synchronizes official Upstream Engine v0.1.35 with our custom StrataRealLowVRAM low-VRAM optimizations, pre-tuned model configurations, and developer tools.

🛠️ StrataRealLowVRAM Key Features in v0.1.35

  1. WDDM 4GB Expert Cache Patch (patched: true):
    • Eliminates Windows WDDM driver clamp where prior memory overcommit falsely zeroes out the expert cache.
    • Restores full 700-slot (Q2_0) and 600-slot (Coder) GPU residency on 4GB cards.
  2. Upstream v0.1.35 Integration:
    • Fix Niko1221#467 (Windows 32GB Working Set Trimming): Restores +1.86 GiB of available physical RAM on startup via SetProcessWorkingSetSize, allowing the full resident cache complement to lock cleanly in RAM.
    • Fix Niko1221#448 (Multi-GPU Prompt Chunking): Intelligent handling of asymmetric VRAM cards.
    • Fix Niko1221#460 (JSON API Resilience): Graceful decoding of double-encoded message strings.
    • Fix Niko1221#457 (Speculative Metrics): Cumulative /metrics counters for draft acceptance.
    • Fix Niko1221#459 (Atomic Configs): Safe atomic config writes via temporary files.
  3. Pre-Tuned Champion Configurations:
    • strata-q2_0.json: 700 expert cache slots, 6 pool workers, adaptive swaps 4/8, Direct I/O queue depth 256, prefill chunk 2048.
    • strata-coder-iq1_m.json: 600 expert cache slots, 6 pool workers, adaptive swaps 4/8, Direct I/O queue depth 256, prefill chunk 2048.
  4. Antigravity Model Context Protocol (MCP) Server:
    • Official stdio MCP server (tools/strata_mcp.py) and CLI bridge (tools/mcp_cli.py) for AI assistants (Antigravity, Claude Code, Cursor).
  5. Engine Auto-Update Shield:
    • setup.py protects custom compiled and patched local binaries from being overwritten by vanilla upstream downloads.

📦 Release Assets

  • StrataRealLowVRAM-v0.1.35-full-windows-x64.zip: Complete ready-to-run installation bundle. Just extract and double-click START-HERE.bat or run-q2_0.bat.
