assort 2.0.0

Using AI to sort lists of unstructured text through iterative batches.

assort

Text clustering and sorting with an LLM that discovers categories, classifies items, optionally merges overlapping themes, and cleans up labels. Designed for quick drop in use with a single function call and clear cost tracking.

Highlights

• Discovers category names from your data
• Sorts each item with calibrated confidence per category
• Merges overlapping themes when the model judges a high likelihood of overlap
• Refines the miscellaneous bucket when it is too large
• Optionally renames categories to be clearer and more specific
• Tracks tokens and final cost in USD
• Simple one function API that returns results and rich stats

Install

pip install assort

You also need an OpenAI API key available to the runtime, for example

export OPENAI_API_KEY=sk_your_key_here

Quick start

from assort import assort

texts = [
    "Build a responsive landing page in React",
    "How to index a Postgres table",
    "Cognitive behavioral therapy exercises",
    "Vector search with Azure AI Search",
    "Tailwind utility classes for layouts",
    "Managing anxiety before a big presentation",
]

results, stats = assort(
    texts,
    min_clusters=3,
    max_clusters=6,
    description="Short notes that mix software topics and mental health topics",
)

print(results["sorted_results"])

Example shape of sorted_results

{
    "Front End Engineering": [
        "Build a responsive landing page in React",
        "Tailwind utility classes for layouts"
    ],
    "Data and Search": [
        "Vector search with Azure AI Search",
        "How to index a Postgres table"
    ],
    "Anxiety and CBT": [
        "Cognitive behavioral therapy exercises",
        "Managing anxiety before a big presentation"
    ],
    "Miscellaneous": []
}

API

assort

results, stats = assort(
    batch,
    min_clusters=2,
    max_clusters=5,
    description="",
    model=None,
    rename_final=True,
    show_progress=False,
)

Parameters

• batch List of strings to categorize. Empty or blank strings are ignored.

• min_clusters and max_clusters Bounds for initial category discovery.

• description Optional corpus context. Helps the model choose better category boundaries and names.

• model Optional model name to override the default. If omitted, a capable multimodal GPT model is used by default.

• rename_final If true, the library proposes clearer category names at the end based on samples from each group.

• show_progress If true, displays progress while items are assorted.

Returns

• results Dict with key sorted_results. Values are lists of the original items per category. A Miscellaneous bucket is always present.

• stats Dict with detailed run information

  • model
  • items_total
  • initial_categories_count
  • final_categories_count
  • miscellaneous_count
  • calls with counts for internal steps
  • retries for API retries with backoff
  • tokens with input and output counts
  • combination_attempts and combined_merges
  • elapsed_seconds
  • cost_usd calculated from token counts and the internal price table
  • category_sizes mapping category to item count

How it works

• Category discovery The model reads a sample of your corpus and proposes a set of category names between your bounds.

• Sorting Each item is scored for every discovered category with confidences high, medium, low. High confidence categories win. Ties are broken by simple rules.

• Combining overlapping themes When items frequently score high for the same pairs or sets of categories, the library asks the model if they should be combined. On a high decision, a single concise name is requested and the merge proceeds.

• Refining miscellaneous If Miscellaneous grows larger than a data guided threshold, the same discovery and sorting routine runs on that subset. Items are pulled out into new focused categories when possible.

• Renaming for clarity At the end, the library proposes clearer names that preserve meaning using a small sample from each category. Names are deduplicated.

Cost and tokens

• Token accounting uses tiktoken with an encoder chosen for the active model.
• The final cost_usd is calculated from token counts and an internal price table.

Advanced examples

Run and keep original names

from assort import assort

texts = [...]
results, stats = assort(
    texts,
    min_clusters=4,
    max_clusters=8,
    description="Product feedback notes",
    rename_final=False,
)

Inspect stats for simple analytics

results, stats = assort(texts)

sizes = stats["category_sizes"]
by_size = sorted(sizes.items(), key=lambda kv: kv[1], reverse=True)
for name, count in by_size:
    print(name, count)

Behavior notes

• Non deterministic sampling is used during corpus selection, so runs can vary.
• The module keeps a single OpenAI client and encoder in module scope. In process concurrency is not recommended. Use separate processes for parallel work.
