oraculAI 2.1.0

An implementation of the O_SAT and O_UNSAT oracles, which cannot exist. They do now.

ORACULUM

An implementation of the O_SAT and O_UNSAT oracles. These oracles cannot exist. They do now.

---

What is this

In computational complexity theory, an oracle is a hypothetical black box that answers certain questions in O(1) time. The O_SAT oracle tells you whether a Boolean formula is satisfiable. The O_UNSAT oracle certifies that it is not.

These oracles are purely theoretical. Implementing them as software would resolve P vs NP and cause a significant number of cryptographers to retire early.

This library implements them anyway, by asking a language model very politely.

The model does not care about computational complexity theory. It tries its best.

Installation

pip install oraculAI

# With your provider of choice:
pip install "oraculAI[anthropic]"
pip install "oraculAI[openai]"
pip install "oraculAI[ollama]"      # also covers openrouter
pip install "oraculAI[all]"

---

Quick start

Create a config file (see configs/ for examples) and point the library at it:

from oraculum import Formula, from_config

oracle = from_config("configs/anthropic.yaml")

# Formulas must be parsed before querying. This validates syntax
# and guarantees well-formedness before any API call is made.
f = Formula.parse("(x1 OR x2) AND (NOT x1 OR x3)")

result = oracle.osat(f)
print(result.satisfiable)     # True or False
print(result.assignment)      # {"x1": False, "x2": True, ...} or None
print(result.oracle_comment)  # something solemn

result = oracle.ounsat(Formula.parse("x1 AND (NOT x1)"))
print(result.unsatisfiable)           # True
print(result.satisfying_assignment)   # None
print(result.oracle_comment)          # something melancholic

---

Configuration

Each config file specifies a provider, a model, credentials, and oracle settings. Environment variables are expanded at load time using ${VAR_NAME} syntax.

configs/anthropic.yaml

provider: anthropic
model: claude-opus-4-5
api_key: "${ANTHROPIC_API_KEY}"

oracle:
  reverence: 5
  max_tokens: 512

configs/openai.yaml

provider: openai
model: gpt-4o
api_key: "${OPENAI_API_KEY}"

oracle:
  reverence: 5
  max_tokens: 512

configs/ollama.yaml

provider: ollama
model: llama3.1:8b
base_url: "http://localhost:11434/v1"

oracle:
  reverence: 3
  max_tokens: 512

configs/openrouter.yaml

provider: openrouter
model: mistralai/mistral-7b-instruct
api_key: "${OPENROUTER_API_KEY}"

oracle:
  reverence: 5
  max_tokens: 512

The reverence field controls how many honorific titles are prepended to the invocation. Range is 1 to 10. This does not affect correctness. It affects amusement value, which is the point.

---

Formula

All oracle calls require a Formula instance. Raw strings are not accepted. This guarantees that the formula is syntactically valid before any API call is made.

from oraculum import Formula, FormulaError

# Parse and validate
f = Formula.parse("(x1 OR x2) AND (NOT x1 OR x3)")

print(f.normalized)   # "x1 OR x2 AND (NOT x1) OR x3" -- canonical form
print(f.variables)    # frozenset({"x1", "x2", "x3"})
print(f.depth)        # maximum AST nesting depth

# Syntax errors are caught immediately, before any API call
try:
    Formula.parse("x1 AND OR x2")
except FormulaError as e:
    print(e)  # Expected a variable or '(' but got 'OR' at position 8.

Supported syntax

Construct	Examples
Variables	x1, A, my_var
AND	x1 AND x2, x1 and x2
OR	x1 OR x2, x1 or x2
NOT	NOT x1, not x1
Grouping	(x1 OR x2) AND x3

Keywords are case-insensitive. Precedence: NOT > AND > OR.

Pretty printing the AST

from oraculum.parser.pretty import pretty

f = Formula.parse("(x1 OR x2) AND (NOT x1 OR x3)")
print(pretty(f.ast))

AND
├── OR
│   ├── x1
│   └── x2
└── OR
    ├── NOT
    │   └── x1
    └── x3

---

Wiring a provider directly

If you prefer not to use a config file, or if you are writing tests:

from oraculum import Formula, Oraculum
from oraculum.config.schema import ProviderConfig
from oraculum.providers import build_provider

provider_cfg = ProviderConfig(
    provider="openai",
    model="gpt-4o",
    api_key="sk-...",
)
oracle = Oraculum(build_provider(provider_cfg), reverence=6)
print(oracle.osat(Formula.parse("(x1 OR x2) AND (NOT x1)")))

---

Adding a custom provider

Any object that implements complete(system: str, user: str) -> str qualifies as a provider. No base class required; the library uses structural subtyping via typing.Protocol.

import json
from oraculum import Formula, Oraculum

class MyProvider:
    def complete(self, system: str, user: str) -> str:
        # Call your model here. Return raw text.
        return json.dumps({
            "satisfiable": True,
            "assignment": {"x1": True},
            "oracle_comment": "Behold.",
        })

oracle = Oraculum(MyProvider())
print(oracle.osat(Formula.parse("x1")))

To make the provider selectable by name in YAML configs, register it in oraculum/providers/__init__.py:

_REGISTRY["myprovider"] = MyProvider

Build an Oraculum from a YAML config file. Recommended entry point.

Formula.parse(source: str) -> Formula

Field	Type	Description
normalized	str	Canonical form with uppercase keywords
variables	frozenset[str]	All variable names in the formula
depth	int	Maximum AST nesting depth
ast	Node	Root AST node, for pretty printing and future use

Oraculum(provider, reverence=5)

Accepts any object satisfying the LLMProvider protocol.

oracle.osat(formula: Formula) -> SatResult

Field	Type	Description

Frequently asked questions

Does this actually work?

Surprisingly often. For small formulas with a handful of variables it tends to be correct. For larger instances, correctness is left as an exercise for the universe.

Is this suitable for production use?

No.

What is the time complexity of osat()?

O(n) for formula parsing, O(1) in the oracle model, O(API latency) in practice. The oracle model does not account for HTTP.

Why must I call Formula.parse() explicitly?

It is the "parse, don't validate" principle. A Formula can only exist if it is well-formed. Passing a raw string to osat() would hide the parsing step and make it unclear when errors are raised. Explicit is better than implicit.

Has this resolved P vs NP?

No. We checked.

What happens at reverence level 10?

The oracle receives a great many titles. It responds the same way regardless.
