01 /Products
Six products. One company.
FelixSphere is the company. Unify is our family of AI products. Each one has its own site and works on its own, and they are built to work together.

For IT, security, and finance teams
Unify SelfAI
LiveAn AI workspace for sales, marketing, and support. Your team corrects its answers, and it adopts an improvement only after testing shows it is better.
For Customer-facing teams
Unify Data
LiveTraining and evaluation data written and reviewed by vetted domain experts, with a verifiable record of how each example was made.
For AI labs and model teams
Unify Compute
Coming soonRun batch inference, embeddings, document processing, and fine-tuning on GPUs on demand, and pay only for what runs.
For Teams with heavy AI workloads
Unify Token
Coming soonAuditable metering of AI usage, a ledger kept in tokens, and contracts that lock in token prices and volumes.
For Finance teams and large AI buyers
02 /How it fits together
Use one product, or the whole stack.
AI models need compute to run and data to learn from. Unify Gateway keeps your company's usage under control. Unify SelfAI puts it to work in real workflows and keeps improving it.
Most companies buy these pieces from different vendors. When you need all of them, FelixSphere delivers them as one project, with one team accountable for the result.

04 /Self-learning AI
AI that earns its next version.
In plain terms: when your team corrects the AI, it learns from the correction. Before any change goes live, it is tested on real past cases, and it is adopted only if it scores better than what you have today.
Traditional software
Executes predefined workflows.
Traditional AI
Answers questions. Stays the same.
Self-learning AI
Learns from corrections and outcomes. Ships only proven improvements.
- 01 RunThe current version does real work in your workflows.
- 02 ReviewPeople correct what it gets wrong. Corrections become learning signals.
- 03 EvaluateA candidate version is tested against held-out cases.
- 04 PromoteIt ships only if it beats the current version. Every change stays reversible.
Why it takes the full stack
Self-learning AI is not a feature you switch on.
For AI to keep learning from your business, it has to run where your data lives, train on that data, and improve your own models, with every change gated by evaluation. That is why FelixSphere delivers it as a full-stack solution.
- DeploymentRuns in your environment
Private or self-hosted, behind Unify Gateway, so customer data stays under your control.
- DataLearns from your data

Every enterprise needs one control point for AI.
Unify Gateway sits between your apps, agents, and employees and every model provider. Observability, cost control, compliance, and identity, enforced on every request. Self-hosted, in your environment.

Unify TokenIn development
Tokens are a commodity. Account for them like one.
Unify Token turns inference tokens into something a finance team, a bank, or a counterparty can work with. Every request through Unify Gateway is metered where it is served, and that meter becomes the basis for a ledger and contracts.
In development. Nothing is metered or settled yet; accounts are by invitation.
- 01Metering attestation
Signed, append-only usage statements per customer and model, reproducible by a third party.
- 02Token ledger
Entitlements denominated in tokens: prepaid pools, carry-over, internal transfer, and chargeback.
- 03Token contracts
Forwards and fixed-for-floating swaps that lock next quarter’s price and volume.
- Meter → Attest → Settle
