The Infrastructure of Uncensored Intelligence

The uncensored AI API: Shannon models with no refusals and no filters, served from our own GPUs. OpenAI- and Anthropic-compatible — drop in the SDK you already use, one key, streaming, tool calling and reasoning on every endpoint.

Modelos

SELF-HOSTED

Eight Shannon tiers and twelve hosted open-weight models, all behind the same endpoint. Each hosted id accepts what the model it imitates accepts — seven of the twelve are text-only. Model ids are stable — pin them in production.

What each id accepts

The same values GET /v1/models returns. Every id streams and takes tool definitions; input and structured output vary, because a hosted id accepts exactly what the model it imitates accepts.

Streaming

Server-sent events, OpenAI chunk format. Thinking models stream reasoning_content deltas before the answer; the final chunk carries exact usage.

Python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.shannon-ai.com/v1"
)

# Enable streaming for real-time responses
# Thinking models stream reasoning_content first, then content
stream = client.chat.completions.create(
    model="GLM-5.2-3BIT-REAP",
    messages=[
        {"role": "user", "content": "Write a short poem about AI"}
    ],
    stream=True
)

for chunk in stream:
    delta = chunk.choices[0].delta
    if getattr(delta, "reasoning_content", None):
        print(delta.reasoning_content, end="", flush=True)  # thinking stream
    if delta.content:
        print(delta.content, end="", flush=True)

Responses API

NEW

POST /v1/responses — the OpenAI Responses dialect: instructions, input items, function_call / function_call_output for tool loops, reasoning summaries as output items. Same models, same key.

Python
from openai import OpenAI

client = OpenAI(api_key="YOUR_API_KEY", base_url="https://api.shannon-ai.com/v1")

response = client.responses.create(
    model="shannon-3",
    instructions="You are a concise assistant.",
    input="Summarize the three-way handshake in two sentences.",
    reasoning={"effort": "low"},
)
print(response.output_text)

# Tool loop: function_call items come back in response.output; answer them
# with function_call_output items on the next call.

Streaming emits response.created, reasoning_summary_text.delta, output_text.delta, function_call_arguments.delta and response.completed; a failed generation ends with response.failed. Non-streaming is the default.

Reasoning effort

NEW

Every thinking model streams its trace as reasoning_content deltas (or a thinking block) before the answer, and finish_reason: length tells you the answer hit max_tokens. The depth knob — reasoning_effort on /v1/chat/completions (off, low, medium, high), reasoning.effort on /v1/responses, thinking.budget_tokens on /v1/messages — is read by the hosted open-weight models; the Shannon tiers accept it and choose their own depth. GET /v1/models reports reasoning_effort per model.

Python
from openai import OpenAI

client = OpenAI(api_key="YOUR_API_KEY", base_url="https://api.shannon-ai.com/v1")

# reasoning_effort: off | low | medium | high. Read by the hosted open-weight
# models, where it sets how long the solve pass thinks. Shannon tiers accept the
# field and pick their own depth -- GET /v1/models reports which is which.
stream = client.chat.completions.create(
    model="GLM-5.2-3BIT-REAP",
    reasoning_effort="medium",
    stream=True,
    messages=[{"role": "user", "content": "Is 221 prime?"}],
)
for chunk in stream:
    delta = chunk.choices[0].delta
    if getattr(delta, "reasoning_content", None):
        print(delta.reasoning_content, end="", flush=True)   # thinking
    if delta.content:
        print(delta.content, end="", flush=True)             # answer

Formato Anthropic

Drop-in for the Anthropic SDK — point it at our base URL and keep your Messages code.

https://api.shannon-ai.com/v1/messages
Python
import anthropic

client = anthropic.Anthropic(
    api_key="YOUR_API_KEY",
    base_url="https://api.shannon-ai.com"
)

response = client.messages.create(
    model="shannon-3",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Hello, Shannon!"}
    ],
    # Tool use (Anthropic format)
    tools=[{
        "name": "web_search",
        "description": "Search the web",
        "input_schema": {
            "type": "object",
            "properties": {
                "query": {"type": "string"}
            },
            "required": ["query"]

CLI coding tools

NEW

Use Shannon as the model behind Claude Code, Codex CLI and other agent CLIs.

Claude Code

Anthropic's official CLI coding agent. Point it at Shannon to use as your AI backend for reading, editing, and running code directly in your terminal.

ANTHROPIC_BASE_URL=https://api.shannon-ai.com ANTHROPIC_API_KEY=sk-YOUR_KEY claude

Codex CLI

OpenAI's open-source coding agent. Uses the Responses API for multi-turn tool use, file editing, and shell commands — all routed through Shannon.

OPENAI_BASE_URL=https://api.shannon-ai.com/v1 OPENAI_API_KEY=sk-YOUR_KEY codex

Claude Code

Shell
# Install Claude Code (requires Node.js 18+)
npm install -g @anthropic-ai/claude-code

# Connect to Shannon AI as backend
export ANTHROPIC_BASE_URL=https://api.shannon-ai.com
export ANTHROPIC_API_KEY=sk-YOUR_API_KEY

# Launch Claude Code in bare mode (no Anthropic account needed)
claude

# Or run a one-shot command
claude -p "Explain this codebase"

# Claude Code will use Shannon's Anthropic-compatible API
# for all AI operations: reading files, editing code,
# running tests, and multi-turn tool use.

Codex CLI

Shell
# Install Codex CLI
npm install -g @openai/codex

# Connect to Shannon AI as backend
export OPENAI_BASE_URL=https://api.shannon-ai.com/v1
export OPENAI_API_KEY=sk-YOUR_API_KEY

# Launch Codex
codex

# Or run a one-shot command
codex "fix the bug in main.py"

# Codex uses the Responses API (POST /v1/responses)
# Shannon handles tool calls including:
# - Reading and writing files
# - Running shell commands
# - Multi-turn function calling
