Rocktalk Lens — Semantic Coordinates

Map any text into a 22-dimensional universal information space. Every concept gets a coordinate. Compare semantic positions, find structural relationships, build new representations.

A Universal Information Space

Every concept has a position in a 22-dimensional semantic space. The dimensions are not arbitrary — each captures a distinct primitive category of meaning found across all domains of knowledge.

Rocktalk Lens encodes text into coordinates across 22 semantic primitives. You can compare positions, find clusters, measure how concepts relate structurally — not just by word overlap.

Works across languages, domains, and levels of abstraction. "The speed of light" and "the maximum constraint on information transfer" land near each other. "Democracy" and "shared decision structure" converge. Structure is meaning.

python — encode text
# Rocktalk Lens — encode any text
import requests

r = requests.post(
    "https://api.rocktalk.ai/v1/lens/encode",
    headers={"Authorization": "Bearer sk_rt_YOUR_KEY"},
    json={"text": "love is patient"}
)

data = r.json()
coords = data["results"][0]["coordinates"]
top    = data["results"][0]["top_dimensions"]

# coords → list of 22 floats
# top    → [{index, meaning, value}, ...]
Research use: cite as Rocktalk Labs Lens with the API endpoint URL. Lens output is deterministic — same input always returns the same coordinate.

Each dimension index maps to a universal semantic primitive.

OpenAI-Compatible API

Change one line of code. Point your existing OpenAI client at https://api.rocktalk.ai/v1 and use model qwen3.5.

python — openai sdk
from openai import OpenAI

client = OpenAI(
    base_url="https://api.rocktalk.ai/v1",
    api_key="sk_rt_YOUR_KEY"
)

response = client.chat.completions.create(
    model="qwen3.5",
    messages=[{
        "role": "user",
        "content": "Explain entropy briefly."
    }]
)

print(response.choices[0].message.content)
curl — streaming
curl https://api.rocktalk.ai/v1/chat/completions \
  -H "Authorization: Bearer sk_rt_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "qwen3.5",
    "stream": true,
    "messages": [{
      "role": "user",
      "content": "What is 2+2?"
    }]
  }'

Streaming uses server-sent events (SSE). The response format matches the OpenAI API spec exactly — including delta.content chunks.
