The Nyquest App is the primary product. Around it: a public REST API for developers, a self-hosted engine for air-gapped deployments, and a browser extension. Pick what fits how you work.
// Primary Product
Nyquest App — app.nyquest.ai
LIVE
A full AI workspace. Talk to models from every major provider through one interface. Smart routing across tiers, model pinning, web grounding, persistent memory with vector recall, agent mode, artifacts (14 file types), audio + image generation, and ten distinct visual chassis — all in one place.
Free has access to BYOK plus whichever models are currently no-cost in the catalog. Pro unlocks every model — Sonnet 4.6, Opus 4.7, GPT-5.5, and the rest. Circuit breakers fail over between tiers automatically; you always know which model handled which request.
Model Pinning
Lock any conversation to a specific model. Your pinned model handles every message in that thread — no routing surprises, no model switching mid-conversation.
BYOK
Bring your own API keys for OpenAI, Anthropic, Google, xAI. Keys are AES-256-GCM encrypted at rest and used for direct provider calls. Your rates, your billing.
Web Grounding
Live web search and full-page fetch injected into context before the model responds. No Tavily key required — built in. Responses cite the URLs they used.
Memory + Recall
Conversations persist. A separate memory system extracts facts across sessions, sanitizes PII, and recalls relevant ones via vector search at chat time. Confidence-scored.
Agent Mode
Multi-step planner that decomposes a request, runs tools (search, fetch, artifact creation, memory query), and streams steps over SSE. Per-run guardrails on cost, time, and steps.
// Chassis & Customization
Ten chassis. Same workspace, different soul.
Same data, same flows, ten radically different aesthetics. Each chassis is a complete visual identity — its own typography, palette, copy, and ambient effects. Switch any time. All chassis are included.

Same data, different surface
Every chassis renders the same conversations, the same memory, the same artifacts. Switching is purely visual — no state migration, no settings to re-enter.
Per-chassis copy + ambience
Each chassis ships its own templates and ambient overlays — quant has the live ticker, matrix has scanlines, apsis has a starfield. Beyond palette, the workspace feels different.
WCAG-AA throughout
Every chassis is contrast-tuned for readability. Even matrix and studio meet AA on body text. No theme is for show only.
All ten chassis included on every account. Switch any time from the chassis modal.
// BYOK — Bring Your Own Keys
Use your own API keys. Pay provider rates directly.
BYOK is a first-class feature. Plug in your API keys for any supported provider and your requests go directly to that provider under your billing. No token resale. No middleman markup. No surcharge.
🔐
AES-256-GCM at rest
Keys are encrypted the instant you paste them. Per-key nonce stored alongside ciphertext. Decrypted in memory only at dispatch. Never logged, never cached in plaintext, never sent anywhere except the provider you chose.
🔀
Direct provider passthrough
With BYOK, your request goes directly from Nyquest to the provider's API using your key. You pay the provider's published rate — or whatever volume discount you've negotiated. Nyquest adds zero token markup.
⚙️
Per-provider adapters
Each provider gets its own adapter handling auth, request shape, and streaming quirks. You can mix BYOK for one provider with hosted billing for others — the dispatcher routes accordingly.

Supported providers
OpenAI (GPT-5.5, GPT-5.5 Pro, GPT-5.4 Mini, GPT-5.4 Nano) · Anthropic (Claude Opus 4.7, Sonnet 4.6, Haiku 4.5) · Google (Gemini 3.1 Pro, 3 Flash) · xAI (Grok-3) · Any compatible endpoint via custom base URL.
Enterprise-friendly
Already have enterprise API agreements with volume pricing? BYOK preserves your negotiated rates. Committed-use discounts, reserved capacity, org-level billing — all stay intact.
Key management
Add, rotate, or remove keys any time in Settings → Providers. Each key is scoped to its provider. Mix and match BYOK and hosted billing per provider.
// Public API
Public REST API — api.nyquest.ai
LIVE
Same routing, same models, same wallet — accessible programmatically. Issue an API key from your account and integrate Nyquest directly into your apps, agents, or scripts.
OpenAI-compatible
POST /v1/chat/completions with streaming SSE. Drop-in replacement for any OpenAI-compatible client — just point base_url at https://api.nyquest.ai and pass your nq-v1-... key.
Stateless by design
API-key requests skip memory recall and conversation persistence. Each call is independent — no surprising prior-context bleed. Mirrors industry-standard developer-API behavior.
Same wallet, same routing
API requests draw from your wallet balance and route through the same dispatcher tiers as the app. Pin a model with model=... or let the router choose. BYOK works here too.
Manage keys in Settings → API Keys. Per-key usage and rate-limit tracking. Revoke any time.
// Self-Hosted
Compression Engine — Open Source, MIT/Apache-2.0
v3.2.0
The compression engine that powers the platform is open-source. Run it on your own infrastructure, behind your own firewall. Prompts never leave your network. Built for privacy-sensitive and air-gapped environments. v3.2.0 adds a published Docker image — pull from GHCR or build from source.
Identical to what runs behind app.nyquest.ai. Six-stage pipeline: normalize, OpenClaw agent mode, cache reorder, regex compression (532 rules across 19 categories with RegexSet prefilter and bounded LRU cache), local LLM semantic stage, auto-scale + forward. Sanitized for public release.
Docker or bare metal
Multi-stage Dockerfile (Rust builder + Debian-slim runtime, non-root user, tini PID-1) auto-published to ghcr.io/nyquest-ai/nyquest-engine on every release tag. Or build the single Rust binary from source with the one-shot installer. Runs on a Raspberry Pi (rules only) or with GPU for the semantic stage.
Open source
MIT/Apache-2.0 dual license. Nyquest-ai/nyquest-rust-fullstack-3.2.0. GitHub Actions CI · 47 / 47 tests passing · Docker auto-publish on tag. Privacy mode by default — no telemetry, no phone-home, prompts never logged.
Chrome extension that intercepts prompts on Claude, ChatGPT, Gemini, and Grok. Applies 281 compression rules locally before send — no proxy, no server, no account required.
