Common questions about SOPHIA XT.

SOPHIA XT is an operator-built AI implementation company in St. Louis, MO. We run technical service businesses (The Appliance Guys, HVAC Guys), ship the operational software those businesses need (DiagBuddy, Lead Leak Scanner, Sophia Key 3M), and publish underlying research as open releases (Cassandra T1 on GitHub under Apache 2.0).

St. Louis, Missouri, United States. We serve the United States and worldwide via remote engagement.

SOPHIA XT LLC was founded in 2024 by Thomas Garren.

We operate the same kinds of businesses we serve. Recommendations have to survive on our own dispatch board before being shipped to clients. Operator + builder + researcher under one roof is unusual in this market.

Yes. Our flagship service (AI Implementation Assurance) explicitly recommends skipping AI when a process change, dashboard, API integration, or simpler automation would be more cost-effective. We don't automate everything — we build only what makes operational sense.

Thomas Garren — Founder & Chief AI Architect. Operating partner Chris Becker (Becker Service Group). Both are based in St. Louis, MO.

Thomas runs SOPHIA XT alongside operating responsibilities at the Becker Service Group with Chris Becker. Operating background covers appliance repair and HVAC — exactly the customer profile SOPHIA XT serves. The combination of live service-business operator, shipping product owner, and public frontier-research contributor is the central reason SOPHIA XT exists.

Three core services. (1) AI Implementation Assurance — workflow audit, AI/automation readiness review, build-vs-skip recommendation per use case. (2) Automation Systems — workflow automation, API wrappers, routing/logistics, dashboards, custom stack applications, ongoing development retainers. (3) Custom Model Design & Training — when the business case justifies it. Plus a free Lead Leak Scanner conversion-audit tool.

A 48-Hour Workflow Audit is $297. A 7-Day Page Fix starts at $1,500. Monthly AI Operations Support starts at $500/month. Final pricing is set per engagement after a discovery call.

Yes. We build automation, API integrations, dashboards, simulators, routing systems, and custom applications when AI is not the right answer.

Cassandra T1 is an open-released masked-diffusion language model from SOPHIA XT, available at github.com/Chorozion/Casandra-t1-diffusion-edge-model under Apache 2.0. The repository ships a verified epoch-5 FP16 checkpoint (~2.66 GB), tokenizer, PyTorch architecture, and training/inference scripts. T1-Base is a 28-layer transformer with 2,048 hidden, 32,768 vocabulary, grouped-query attention (16 query / 4 KV heads), RoPE, RMSNorm, SwiGLU, and 12 default denoise steps.

No. SOPHIA XT does not publish benchmark numbers it has not measured publicly. The repository includes a captured 10-prompt qualitative coherence comparison and recorded training-loss values (epoch 1 loss 3.78 → epoch 5 loss 2.2561), but does not include MMLU, HumanEval, GSM8K, or similar standard-suite results.

No — it is positioned explicitly as a research-stage proof-of-concept. The architecture and training path work, the verified checkpoint is real and runnable, but output quality still needs more training and structured evaluation before any production use. Long-form generation is unstable; short factual answers are more reliable.
