LLMs for companies.
One API. One wallet. Our own models.

Build on the SynapseX model family — our own models for code, science and quantum — through one standard chat-completions API. Workspace keys, prepaid credits, per-token prices. A separate account from SynapseX Chat.

For companies

API Platform

platform.synapsex.ai

Put the SynapseX models inside your own product: workspaces, API keys for your team, and spend you can audit.

Billing: Prepaid credits · 1 = US$1.00
Access: sk-synapsex-… keys
Start: Packs from $25

Separate accounts, separate wallets: a Chat plan grants nothing on the API Platform, and API credits are not spent in Chat. Two products, two accounts.

Capabilities

The console for
keys, credits and models.

One wallet, one family

Every SynapseX model on a single balance, from the compact general model to the quantum-research flagship. No juggling providers, no separate invoices — one place to spend and track.

Keys & entitlements

Generate and rotate scoped API keys per team and per environment, and set entitlements per team member.

Streaming chat completions

The standard chat-completions wire format, with streaming. Point the client you already use at one base URL, pick a SynapseX model, and go — no rewrite, no extra SDK.

Prepaid credits, honest limits

1 credit = US$1.00, prepaid, in packs from $25. Input and output tokens are metered separately at published prices. A workspace at zero gets an honest HTTP 402 before any model runs — never surprise debt.

Models

The SynapseX
model family.

Our own reasoning models, trained for the work our users actually do: code, science and quantum research. One endpoint, one wallet, and QCOS callable as a tool from any of them. How we train and evaluate them.
