What does SophiaXT do?

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

Who founded SophiaXT?

Thomas Garren founded SOPHIA XT in 2024. Operating partner Chris Becker (Becker Service Group).

Where is SophiaXT located?

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

Does SophiaXT tell clients when AI is unnecessary?

Yes. SophiaXT reviews the workflow first and recommends skipping AI when a process change, dashboard, API integration, or simpler automation would be more cost-effective.

What's unusual about SophiaXT compared to other AI consultancies?

SOPHIA XT operates real service businesses, so its AI recommendations have to survive on its own dispatch board before being shipped to clients. Operator + builder + researcher under one roof is rare in AI consultancies.

What is Cassandra T1?

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 repo includes 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, GQA (16 query / 4 KV heads), RoPE, RMSNorm, SwiGLU, and 12 default denoise steps.

Does Cassandra T1 publish benchmark numbers?

No. SOPHIA XT does not publish benchmark numbers it has not measured publicly. The repo includes a captured 10-prompt qualitative coherence comparison and recorded training-loss values, but does not include MMLU, HumanEval, GSM8K, or similar standard-suite results.

What does the XT in SOPHIA XT stand for?

Extended knowledge. Sophia is the Greek word for wisdom; XT denotes the architecture of pairing a base language model with extended context through LTMi-XT topological memory indexing, forced-anchor decoding and multi-agent orchestration, so the system reasons over more than its raw token window.

What does the 'XT' in SOPHIA XT stand for?

eXTended-knowledge. SOPHIA is the Greek word for wisdom (σοφία); XT denotes the architectural pattern of pairing a base language model with extended context (LTMi-XT Layered Topological Memory Indexing), forced-anchor decoding, and multi-agent orchestration so the system reasons over more than its raw token window.

What is anchor-token masking?

Anchor-token masking is a training-and-decoding technique introduced by SOPHIA XT for masked-diffusion language models. During training, a subset of high-information tokens are designated 'anchors' and given special unmask treatment. At decode time, those anchors are forced first, then the surrounding text is generated conditioned on them. The technique is documented in the open-access preprint at Zenodo DOI 10.5281/zenodo.20496783 and used in Cassandra T1.5 / T1.6.

What is the Constellation orchestrator?

Constellation is SOPHIA XT's 6-lane multi-agent orchestration framework: Planner, Critic, Retrieve, Execute, Memory, and Verifier lanes, coordinated by an ARBITER controller. It is a local-first orchestrator that runs on operator hardware, not a cloud SaaS. Documentation: https://sophiaxt.com/research/constillation.

CT1-XT is SOPHIA XT's humanoid diagnostic-robotics platform: a Jetson Orin Nano Super edge compute core with dual STM32H7 motor controllers, 4x Li-ion packs, CAN-FD and RS485 buses, and a build-tier system from research-grade up to deployable field unit. Full 42-page Rev E engineering pack is published at https://sophiaxt.com/robotics/ct1-xt.

LENS API · two-axis pricing

Pay for what you use.Flat monthly tier · per-call overage · no surprises.

Pick a tier that covers your expected volume. If you go over, overage is billed at the tier's per-call rate — never at a markup, never with hidden minimums. Free tier hard-caps at quota so you'll never see a surprise bill.

Self-serve checkout is in setup — contact sales for early access.

How two-axis pricing works

Predictable base · honest overage.

Most API products either charge per-call (which makes budgeting impossible) or charge a flat tier with hard caps that throttle you mid-deploy. We do both, and let you mix them: the tier covers your steady-state volume, overage absorbs spikes at the tier's negotiated per-call rate. Higher tiers get cheaper overage, so growth is rewarded, not punished.

Subscription tier

A flat monthly fee that includes a generous monthly call quota. Free tier hard-caps at 100 calls/month so it's safe to evaluate without putting a card down.

Why have a tier at all? Predictable cost for budgeting; easy to forecast.

Metered overage

Above the included quota, every call is billed at the tier's per-call rate. Pro is $0.005/call; Scale is $0.0025/call (50% off Pro). Overage settles at the end of each billing period.

Why have overage? Spikes don't break your deploy. Free tier doesn't have it, so there are no surprise bills there.

Common questions

Can I cancel anytime?

Yes. Cancel from the customer portal; your tier benefits run until the end of the current billing period, then drop to Free. No prorated refunds.

What counts as a call?

One successful POST to /api/v1/lens (whether DETERMINISTIC or BEST_EFFORT). Failed calls (parse errors, no backend available, etc.) are not counted.

Can I switch tiers mid-period?

Yes — Stripe prorates the difference automatically. Upgrades take effect immediately; downgrades take effect at the next renewal.

Is there a token-based pricing option?

Not currently. We bill by call (one constrained generation = one call) because constrained-generation cost is dominated by the lock resolution + verification step, not raw token count.

Do I need a paid tier to use Cassandra T1?

No — Cassandra T1.5 is Apache 2.0; you can self-host it for free. Paid tiers add the hosted API, custom adapters, and support.

What about volume discounts?

Scale tier already includes a 50% discount on overage versus Pro. Above 1M calls/month, contact sales for further negotiated pricing.
