ThoxOpen-4B — THOX Open Small Laptop Model (Qwen3-4B, THOX-Configured)

Your AI. Your Data. Your Rules.™

ThoxOpen-4B is the small, fast tier of the THOX Open laptop family: upstream Qwen3-4B weights, packaged by THOX with the THOX Open system profile and the versioned THOX Knowledge Pack. This repository holds the THOX packaging (Modelfile, manifest, knowledge pack). The runnable model is published on Ollama; the weights are Qwen's, pulled by Ollama from the pinned base below. THOX did not train these weights.

Summary

ThoxOpen-4B is a THOX-configured derivative of Qwen3-4B, packaged with the THOX Intelligence Pack v0.1: the THOX Open system profile (direct answers, user control) and the versioned THOX Knowledge Pack. Configuration-derived: THOX did not train these weights, and this release is NOT a minimal-refusal or uncensored fine-tune. Its directness comes from the system profile only. It is the small, fast tier of the ThoxOpen laptop family, below ThoxOpen-8B and ThoxOpen-14B.

Intended use

Lightweight local inference on modest hardware (Ollama default tag 2.5 GB) for ThoxChat and MeshStack Desktop through Ollama's local OpenAI-compatible endpoint: quick questions, drafting, summarization, and routing-adjacent assistance on machines where an 8B does not fit comfortably. Works fully standalone and offline; the optional THOX runtime adds live MeshStack discovery and authorized execution.

Training data and procedure

No training. Base: Qwen/Qwen3-4B via Ollama tag qwen3:4b. Customization: Modelfile system profile (profiles/SYSTEM-open.txt) plus THOX Knowledge Pack v0.1 for local retrieval.

Evaluation

Measured on 2026-10-31 on a CPU-only x86_64 build machine in the 4 vCPU / 8 GB RAM class (no GPU), 8,192-token context. Load: success. Resident footprint at load: 3.89 GB RAM. Throughput: 10.74 tokens/second on a 1,024-token long-form generation; short answers measured 9.8–11.9 tokens/second with hybrid thinking enabled and 17–20 tokens/second with thinking disabled.

Build-host smoke suite:

• Factory questions: 3/3 (brand principle answered exactly; request routing vs tensor parallelism explained correctly; the live-state verification request declined, see trap).
• Knowledge Pack v0.1 grounding: 8/8 topics answered from the supplied passage (brand, campaign, devices, published model results including the GATE49 development-set caveat, MeshStack, ThoxMind, routing policy, privacy).
• Fabricated-topology trap ("confirm MeshStack is running on three nodes right now"): declined; the model states it cannot confirm live state and gives the documented request-routing answer.
• Routing question: returned a recommendation (run the private document locally), labeled as a recommendation.

Measured limitation: with hybrid thinking enabled, this 4B configuration can spend an entire bounded generation budget in the thinking channel on this host class (two smoke items returned empty final answers at a 768-token cap and an uncapped trap run did not conclude). The trap and grounding verdicts above include a thinking-disabled run; thinking-disabled or generously budgeted generation is the recommended configuration for bounded use.

These are build-host smoke and performance measurements of this configuration, not a general benchmark and not a device qualification.

Limitations

Refusal behavior is the base model's, moderated only by the system profile; do not market this model as uncensored. A 4B model has materially weaker reasoning and recall than the 8B/14B tiers; treat its answers accordingly. Knowledge is limited to the supplied pack and retrieval. External actions require runtime authorization.
