SHANNON LAB LLC

Keep paying — Shannon's proprietary models, curated adversarial benchmark (DarkEval), and compliance posture are durable advantages that a solo developer cannot realistically replicate.

On cash alone, building overtakes the subscription at 18 seats.

The code exists. It is not what you are paying for.

These 2 projects are real, published, and do the core job — and this page still says keep paying. What the subscription buys is proprietary models, proprietary data and compliance and regulation, and none of that ships in a repository. Fork one anyway if you want to. Go in knowing what it does not carry. What stays hard ↓ · All SHANNON LAB LLC alternatives, with the arithmetic →

What a replacement has to do

  • Provide a chat UI that proxies user messages to an LLM API, store short-term memory, surface web-search citations, and support function-calling/tool hooks for agentic workflows.

What it still won’t have

  • Shannon 2 proprietary model and performance
  • DarkEval proprietary adversarial benchmark and exploit coverage
  • Enterprise compliance guarantees (SOC 2 Type II, custom compliance mapping)
  • Built-in web search with integrated source citations and their token-quota model
  • Any gated access to constraints-relaxed red-team models and audit tooling

What remains hard

  • Proprietary modelsOur new flagship, built on the Kimi K2.7 trillion-parameter foundation — frontier-distilled on 30K curated reasoning examples and served in FP8 for professional red-team and security work.
  • Proprietary dataPost-trained on 30,000 curated frontier-grade reasoning and instruction examples for sharper, more reliable answers.
  • Compliance and regulationWe're SOC 2 Type II compliant.

Runnable build prompt

Not run yet
Build a minimal Shannon-like chat+API service using Next.js for the frontend, Node/Express (or Next API) backend, Postgres for memory, Redis for rate-limits/queues, and the OpenAI API (or a hosted open-model) as the LLM. Scope in-scope: streaming chat UI, authenticated API key proxy, token accounting, persistent short-term memory (lookup + store), web-search integration (call a search API and attach top-3 citations), basic function-calling adapter to invoke HTTP tools, and server-side logging. Out of scope: reimplementing Shannon proprietary models, DarkEval benchmark, enterprise SOC2 attestation, and a multi-tenant billing portal. Include error handling, retries, unit tests for API adapters, and end-to-end test for the chat flow.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
