Occamy-1.0 APEX-I-MiniPlus-V2.1 GGUF

The Definitive Frontier MoE · Blistering +24 to 28+ tok/s with System RAM Offload · Full 256K Context on 24GB Workstations

🔓 LOOKING FOR THE UNCENSORED / ZERO-REFUSAL RELEASE?

If your workflow involves red-teaming, penetration testing, systems security research, or unrestricted generation, check out the official sister edition: 👉 Occamy-1.0-APEX-I-MiniPlus-V2.1-Abliterated-GGUF — authentic Heretic TPE directional abliteration with zero moralizing refusals, identical 14.75 GB footprint, and identical high-fidelity 6.2432 WikiText-2 perplexity.

THE DEFINITIVE SPECIFICATION IN THE 13–14 GB CEILING

This APEX-I-MiniPlus-V2.1 release represents the absolute technological limit of sparse Mixture-of-Experts quantization within the 13–14 GB envelope. Every single tensor of its 40 layers and 256 micro-experts has been mathematically audited to maximize reasoning precision, eliminate recurrence state drift, and prevent AVX2 CPU dequantization stalls.

🏆 THE QUANTIZATION SWEET SPOT: Q5–Q6 FIDELITY AT 3-BIT FOOTPRINT

Why APEX-I-MiniPlus V2.1 outperforms standard community quants:

  • Empirical WikiText-2 Perplexity: 6.2432 ± 0.1622 (evaluated directly on GGUF binary, 2048 ctx, 10 chunks) — near-zero loss (ΔPPL ≈ +0.06) from unquantized baseline.
  • Q5–Q6 Quality at 3-Bit Footprint: Delivers reasoning fidelity, complex instruction following, and multilingual coherence typical of Q5_K / Q6_K while occupying only approx. 14.7 GB (same featherweight footprint as Q3_K_M).
  • Zero Routing Drift: 100% of expert routing matrices (gate_inp) remain in uncompressed F32, guaranteeing zero routing distortion across all 256 MoE experts on every forward pass.

DO NOT CONFUSE APEX-I-MINIPLUS WITH GENERIC COMMUNITY APEX-I-MINI!

Regardless of release version (whether V1, V2, or V2.1), NEVER confuse handcrafted APEX-I-MiniPlus builds with generic community APEX-I-Mini releases:

  • Generic Community APEX-I-Mini: Uniformly compresses all core MoE experts down to aggressive 2-bit IQ2_S (dropping below the critical quality floor), leaves the sensitive token output head unarmored at 3-bit Q3_K_M, and compresses attention projections down to Q3_K. In deep reasoning models, this triggers severe perplexity spikes, syntax errors, and broken code brackets.
  • Handcrafted APEX-I-MiniPlus (All Editions by IsValorum): Every single MiniPlus release—from V1 and V2 to V2.1—is a custom tensor-by-tensor architecture that preserves uncompressed F32 router gates, armors the token output head in high-precision Q6_K, safeguards attention gates in Q8_0, and keeps core reasoning experts at or above calibrated 3-bit (IQ3_XXS/IQ3_S). Even our earlier builds vastly outperform generic community APEX recipes and flat 3-bit quants.

Optimization History & Transparency Notice

We maintain our previous releases publicly as a transparent engineering record of continuous optimization. Below is the exact evolutionary roadmap of our MiniPlus architectures:

Specification Core Experts (10–29) Edge Experts (0–9, 30–39) Shared Expert (shexp) Full Attention (L3, 7, 11, ...) Attention Gates (30 Layers) Output Head (output.weight) Routers (gate_inp) Size / Overhead Real-World Impact
Generic APEX Mini IQ2_S (2.50 bpw) Q3_K (only 5 layers) Q4_K / Q3_K Q3_K Compressed Q3_K_M Compressed Baseline (approx. 12.5 GB) Severe syntax errors, broken code indentation, high perplexity in <think>.
MiniPlus V2 (High Theoretical Armor) IQ3_XXS IQ3_S (10 layers) IQ4_NL Q3_K Q8_0 Q6_K F32 +1.2 GB vs generic Heavy theoretical edge envelope. In practice, virtually identical quality to V2.1 even at +160K context. Excellent for 100% VRAM offload.
MiniPlus V2.1 (CURRENT) IQ3_XXS Q3_K (10 layers) Q5_K (All 40 layers) Q4_K (q/k/v) + Q6_K (output) Q8_0 Q6_K F32 < 100 MB extra over V2 (approx. 13.74 GiB total) Zero AVX2 CPU stalls; +24 to 28+ tok/s streaming when offloading bulk of the model to system RAM (DDR4/DDR5). Only approx. 100 MB overhead over V2 (completely negligible in RAM). If 100% in VRAM, both perform identically.

Architecture & Edition Guide — Choosing Between Editions

  • Full GPU VRAM Offload (24GB+ VRAM, -ngl 99): Both V2 and V2.1 run blistering fast on GPU tensor cores with virtually identical top-tier quality.
  • In Practical Long-Context (+160K tokens): Although V2 provides higher theoretical protection on paper, real-world benchmarks show virtually zero perceptible quality difference compared to V2.1 even across deep +160K contexts.
  • System RAM Streaming Specialist (DDR4/DDR5 & Massive Context): V2.1 is specially engineered to run either partially or entirely out of system RAM across large or full (+160k to 256k) context windows. By replacing non-linear codebooks with linear SIMD-optimized Q3_K edge experts and upgrading shared foundation experts to Q5_K across all 40 layers, AVX2 CPU dequantization stalls are completely eliminated (+24 to 28+ tok/s). Depending on your processor architecture and memory bandwidth (dual-channel DDR4 or high-speed DDR5 6000+ MT/s), streaming generation speeds in system RAM can approach speeds remarkably close to full VRAM execution, allowing the dedicated Q8_0 multimodal vision projector (mmproj) to be loaded explicitly in GPU VRAM for instant, zero-latency visual document parsing and OCR while the vast language weights stream economically from system RAM. The approx. 100 MB difference over V2 is completely negligible when running in system RAM.

Both editions are handcrafted and vastly outperform flat 3-bit quants and generic community APEX-I-Mini releases.

Standard Q6_K 6.56 bpw approx. 30 GB approx. +0.02 to +0.05 Near-lossless FP16 fidelity; requires multi-GPU or 32GB+ VRAM setups.
🏆 APEX-I-MiniPlus V2.1 (IsValorum) 3.40 bpw 14.75 GB (13.74 GiB) approx. +0.06 (PPL: 6.2432 vs FP16 approx. 6.18) Near-lossless Q5_K / Q6_K quality tier at an 80% VRAM reduction. Full native 256K context on standard 24GB workstations.
Standard Q5_K_M 5.50 bpw approx. 25 GB approx. +0.05 to +0.10 Commercial transparent threshold; exceeds standard single 24GB GPU limits.
Standard Q4_K_M 4.50 bpw approx. 20 GB approx. +0.15 to +0.25 Standard industry trade-off; requires context offload compromises.
Standard Q3_K_M / Q3_K_S 3.44 bpw approx. 15.5 GB approx. +0.40 to +0.85 Noticeable syntax drop, bracket corruption, and tokenizer classification noise.
Standard IQ2_S / Generic APEX Mini 2.50 bpw approx. 12.5 GB approx. +1.50 to +3.00+ Severe reasoning breakdown, high perplexity spikes in <think> chains.

🏅 Independent Benchmark of the APEX-I-MiniPlus Family (Occamy V2 Reference)

The benchmark below was performed on Occamy-1.0 APEX-I-MiniPlus V2, not on this specific V2.1 model. It is included as independent evidence of the broader MiniPlus quantization approach.

An extensive independent evaluation of Occamy APEX-I-MiniPlus was conducted by AI researcher zephel01 (CoolZero) on an NVIDIA RTX 5090 (32GB) testbed running llama.cpp CUDA b11027 with FlashAttention and FP16/Q8 cache (-fa on -ctk q8_0 -ctv q8_0 -ngl 99). The model was evaluated across 348 unseeded trials on SWE-bench style multi-file Python bug fixes with hidden pytest suites (llmbench):

  • L6 Multi-File Code Generation (60 tasks):
    • Context 32,768 (32K): 93.3% Resolved (46/60 tasks passed 5/5 consecutive trials; 20/20 on Easy–Hard).
    • Context 65,536 (65K): 90.0% Resolved (45/60 tasks passed 5/5 consecutive trials).
    • Match with 25–28 GB Models: Matches or exceeds the resolution rate of full 25–28 GB models (such as Ornith-1.5 and Tiel-Coder 35B-A3B) while consuming over 10 GB less VRAM (14.6 GB vs approx. 26 GB).
  • Extreme Context VRAM Scaling (The Hybrid DeltaNet SSM Advantage):
    • 32K Context: 14.6 GB total VRAM allocation.
    • 65K Context: 15.1 GB total VRAM allocation (only +0.5 GB VRAM added when doubling context!).
    • Architectural Explanation: Because 30 of the 40 layers utilize Linear Attention / DeltaNet SSM ($O(1)$ constant recurrence memory), only the 10 full-attention anchor layers expand the KV cache. This proves empirically that 65,536 context runs 100% in VRAM on consumer 16GB GPUs (RTX 4080 / RTX 5080) without offloading to system RAM.
  • Measured Real-World Throughput: Sustained single-stream generation of approx. 247 – 251 tok/s on NVIDIA RTX 5090.

Hardware Throughput & Offload Benchmarks (RTX 30 / 40 / 50 & RAM Streaming)

Empirically verified in Unsloth Studio & llama.cpp:

Hardware Target Offload Mode Generation Speed (Est.) Prompt Prefill Speed (Est.) Highlights
NVIDIA RTX 5080 / 5090 (Blackwell) Full GPU (-ngl 99) approx. 247 – 251 tok/s 2,800 – 3,900+ tok/s Empirically verified on RTX 5090 by zephel01
NVIDIA RTX 4090 (24GB GDDR6X) Full GPU (-ngl 99) 90 – 115+ tok/s 2,000 – 2,800+ tok/s Linear attention layers slash prefill latency
NVIDIA RTX 3090 (24GB GDDR6) Full GPU (-ngl 99) 72 – 88+ tok/s 1,500 – 2,200+ tok/s Full 256k native window in VRAM
Workstation / Laptop (DDR4 / DDR5 RAM) Hybrid Offload (Few layers in VRAM) 24.25 – 28.37 tok/s 385 – 410+ tok/s Zero AVX2 CPU stalls; fast streaming from system RAM
  • Aggressive Hybrid Offload Profile: Sustained 24.25 to 28.37 tok/s generation with reasoning enabled, even when only approx. 4.2 GB VRAM is available and the rest of the 13.74 GiB model streams from system RAM.

Empirical Testbed Architecture & Desktop/Server Scaling

  • Empirical Benchmark Hardware: The hybrid offload and system RAM streaming figures documented above (sustaining 24.25 to 28.37 tok/s) were measured on a consumer laptop powered by an Intel 12th Gen Alder Lake architecture featuring a hybrid design of Performance Cores (P-Cores) and Efficient Cores (E-Cores) paired with dual-channel system RAM and constrained laptop power/thermal envelopes.
  • Thread Scheduling & E-Core Contention: In hybrid architectures like Alder Lake, OS thread scheduling across background E-Cores and lower single-core mobile power limits introduce memory bandwidth and thread synchronization overhead during CPU dequantization.
  • Dramatic Scaling on Higher-End Processors: When running on desktop or server processors (such as modern AMD Ryzen 7000 / 9000 Zen 4/5 series or high-TDP Intel desktop platforms with dedicated performance cores, large L3 caches, and high-bandwidth dual- or quad-channel DDR5 running at 6000+ MT/s), streaming generation speeds and prefill throughput will scale dramatically higher, substantially exceeding these measured mobile numbers.

The 24GB Miracle: Full 256K Context Runs In VRAM!

Occamy-1.0 APEX-I-MiniPlus-V2.1 fits the entire 256K context window within 24GB VRAM:

Context Length Model Weights (Est.) KV Cache (q8_0, 4 slots) Compute Buffers Total GPU VRAM (Est.) Feasibility
32,768 (32k) 13.74 GiB 0.58 GiB 1.80 GiB 16.12 GiB Full offload on 24GB; partial on 16GB
65,536 (64k) 13.74 GiB 0.92 GiB 1.95 GiB 16.61 GiB Effortless fit on 24GB GPUs
131,072 (128k) 13.74 GiB 1.58 GiB 2.22 GiB 17.54 GiB Effortless fit on 24GB GPUs
262,144 (256k) 13.74 GiB 2.92 GiB 2.80 GiB 19.46 GiB FULL 256K NATIVE IN VRAM!

Note: Leaves comfortable headroom for display drivers and compute buffers on standard 24GB GPUs (RTX 3090, RTX 4090, RTX 5090).

💡 Empirical 16GB GPU Verification (Single Stream / Desktop)

While theoretical multi-slot server buffers estimate approx. 16.5 GiB, independent hardware testing by zephel01 on an RTX 5090 confirmed that single-stream desktop inference consumes only 14.6 GB at 32,768 ctx and only 15.1 GB at 65,536 ctx (-ctk q8_0 -ctv q8_0 -fa on). This empirically proves that full 65K context runs completely in VRAM on 16GB cards (RTX 4080 / RTX 5080) without system RAM offload!

🔍 Model Inherent Behavior vs. Quantization Fidelity Notice

Any behavioral limitations, stylistic habits, or syntactic oversights (such as occasional omitted standard library imports in automated zero-shot scripts, e.g., missing from decimal import ROUND_HALF_UP or @dataclass) stem entirely from the original unquantized base model weights and pre-training distribution, NOT from the APEX-I quantization process. Handcrafted APEX-I-MiniPlus strictly preserves mathematical tensor fidelity—keeping 100% of expert routing matrices (gate_inp) in uncompressed F32 (zero router drift), armoring the token output head in Q6_K, and safeguarding attention gates in Q8_0. Empirical verification confirms near-zero perplexity loss (ΔPPL ≈ +0.06), ensuring that token logits, routing decisions, and reasoning trajectories are mathematically faithful to the original base model.

💡 Developer Tip for Autonomous Coding & CI Agents (Import Discipline)

In third-party evaluations, reasoning and architectural code generation scored a remarkable 90%–93.3% resolution rate on multi-file SWE benchmarks. Any rare failures observed were not reasoning flaws, but occasional omitted standard library imports in zero-shot scripts (e.g. from decimal import ROUND_HALF_UP or @dataclass). When deploying in autonomous coding agents, include in your system prompt: "Always declare complete, explicit import statements at the beginning of the file" or pair with an automated linter (ruff).
