About This Release

BigBang-v1-mtp-oQ3.5e is an independent, standalone MLX oQ quantization of endless-frontier/BigBang-v1. This repository contains exactly one complete oQ3.5e level, not a mixture of alternative tiers.

Selection: browse the BigBang-v1 MTP oQ Quantizations collection to compare the nine standalone levels.
Published artifact: 4 MLX Safetensors shards plus the exact model, tokenizer, prompt, and multimodal preprocessing assets required by this tier.
Maintainer transformation: oQ quantization only; no fine-tuning, merge, behavior edit, DFlash, DSpark, draft weights, or acceleration companion was added.

Notice

Important Notices

This is a community quantization, not an official Endless Frontier release.
A basic family-level smoke test was reported on a MacBook Pro with M4 Max and 128 GB unified memory. The exact oQ tier, macOS version, and MLX runtime version were not recorded.
No independent benchmark, reasoning, development, tool-use, thinking, vision, or long-context evaluation is claimed for this exact oQ3.5e artifact.
Results reported for the source model are not results for this quantization.

Model Details

Format	MLX Safetensors
Modality	Image-text-to-text, inherited from BigBang-v1
Architecture	Qwen3.5 MoE conditional generation, inherited through BigBang-v1
Quantization	oQ3.5e; 3-bit default affine configuration, group size 64, with 281 enhanced per-tensor overrides
Weights	4 shards, 17.436 GiB total repository size
Context	262,144 tokens configured upstream; not independently long-context tested

This page intentionally exposes one selectable quantization level. The Hub can therefore calculate its MLX footprint without summing the other eight alternatives.

Provenance and Lineage

Published artifact: this complete MLX oQ3.5e quantization, prepared by AmixDigital.
Direct source: endless-frontier/BigBang-v1 at revision fe313c9.
Technical ancestor: Qwen/Qwen3.6-35B-A3B, credited by the direct source. It is a technical ancestor, not this release's visual reference.

No fine-tuning, merge, behavior edit, or acceleration model was added by AmixDigital.

Transformation Details

This release was quantized with the oMLX engine through its graphical interface. It uses the oQ3.5e enhanced plan: a 3-bit default affine quantization, group size 64, and 281 recorded per-tensor precision overrides.

The local calibration report identifies oqe_code_multilingual and records 523 entries, 481 applied entries, two missing entries, no mismatches, and one zero-count expert. This is an allocation record, not a quality evaluation.

The machine-readable report is intentionally excluded because it contains a personal local path. The oMLX version and exact build procedure were not recorded.

Requirements and Compatibility

Reported family test environment: MacBook Pro with M4 Max and 128 GB unified memory; basic loading and operation were reported, but the exact tier and software versions were not recorded.
Platform: macOS on Apple Silicon only.
Runtime: an MLX-compatible local runtime supporting the inherited architecture and image/video preprocessing assets.
Memory: minimum unified memory is not independently measured. Disk size is not a safe proxy for memory requirements.
Not claimed: Windows, Linux, CUDA, GGUF, vLLM, or server-GPU compatibility.

Usage

Use this repository as one intact MLX model directory.
Keep its index, all shards, tokenizer, chat template, preprocessor, and video preprocessor configuration files together.
Load it in a compatible local MLX workflow on Apple Silicon.
Begin with short prompts and modest context, then observe memory pressure before increasing the workload.

Prompting, Thinking and Tool Use

The included chat template contains image, video, thinking, and tool-message formatting branches. No end-to-end thinking or tool-use result is claimed for this exact quantization.

Evaluation and Performance

No independent evaluation has been completed for this exact oQ3.5e release. A family-level basic smoke test was reported on a MacBook Pro with M4 Max and 128 GB unified memory, but neither the exact oQ tier nor a metric was recorded. Throughput, latency, memory, reasoning, development, generation quality, vision, tool use, thinking, and long-context behavior remain unmeasured. Upstream scores must not be attributed to this artifact.

08 / 15

Intended Uses

Local experimentation and evaluation on compatible Apple Silicon Macs.
Image-text-to-text research and development with human review.
Comparing oQ storage levels under the user's own controlled workload.

09 / 15

Out-of-Scope Uses

Unsupervised high-stakes medical, legal, financial, employment, safety, or infrastructure decisions.
Autonomous destructive tool execution without sandboxing, review, and recovery controls.
Claims of compatibility not documented in this card.

Risks, Biases and Limitations

Model outputs may be inaccurate, biased, unsafe, fabricated, or unsuitable for a particular context.
Quantization can introduce changes beyond the limitations of the direct source.
The calibration record has two missing entries and one zero-count expert; it is not an assurance of quality.
Minimum memory and functional behavior remain unmeasured.

Recommendations and Mitigations

Evaluate the exact oQ level and intended prompts before use.
Keep human review for consequential outputs and generated code.
Sandbox tool access and protect credentials, private data, and the filesystem.
Monitor memory pressure and stop before macOS memory compression or swapping compromises the workload.
