Swarmauri Measurement Token Count Estimator

Token-count measurement plugin for Swarmauri pipelines. Uses OpenAI's tiktoken library to estimate how many tokens a piece of text will consume given a specific tokenizer (default cl100k_base).

Features

• Implements the MeasurementBase API to slot into Swarmauri observability flows.
• Wraps tiktoken encoders for quick token-count estimation ahead of LLM calls.
• Configurable tokenizer name so you can match counts to different model families.

Prerequisites

• Python 3.10 or newer.
• tiktoken installed (pulled in automatically as a dependency).
• If you use custom encodings, ensure they are registered with tiktoken before invoking the measurement.

Installation

# pip
pip install swarmauri_measurement_tokencountestimator

# poetry
poetry add swarmauri_measurement_tokencountestimator

# uv (pyproject-based projects)
uv add swarmauri_measurement_tokencountestimator

Quickstart

from swarmauri_measurement_tokencountestimator import TokenCountEstimatorMeasurement

measurement = TokenCountEstimatorMeasurement()
text = "Lorem ipsum odor amet, consectetuer adipiscing elit."
count = measurement.calculate(text)
print(f"Tokens (cl100k_base): {count}")

Switching Encodings

from swarmauri_measurement_tokencountestimator import TokenCountEstimatorMeasurement

text = "Swarmauri agents coordinate over shared memory"
measurement = TokenCountEstimatorMeasurement()

for encoding in ["cl100k_base", "o200k_base", "p50k_base"]:
    print(encoding, measurement.calculate(text, encoding=encoding))

Use this to check token budgets across different model families before dispatching a request.

Handling Unknown Encodings

from swarmauri_measurement_tokencountestimator import TokenCountEstimatorMeasurement

measurement = TokenCountEstimatorMeasurement()
invalid_count = measurement.calculate("Hello", encoding="not-real")
print(invalid_count)  # Returns None and prints an error message

Wrap the call if you prefer structured error handling:

try:
    count = measurement.calculate("Hello", encoding="not-real")
    if count is None:
        raise ValueError("Unsupported encoding")
except ValueError:
    # fallback logic
    pass

Tips

• Token counts can change as tokenizers evolve; pin tiktoken to a known version for stable measurements.
• Normalize whitespace if your prompt assembly adds or strips spaces—tokenizers are sensitive to exact byte sequences.
• For batch estimation, combine this measurement with Pandas or list comprehensions to preprocess entire prompt sets before sending them to an LLM.
