Add EMBEDDING_MODEL_CONFIG__DIMENSIONS_MODE (auto|always|never) controlling
whether the dimensions= parameter is forwarded on OpenAI embeddings.create
calls. auto (default) sends it when the operator explicitly set
EMBEDDING_VECTOR_DIMENSIONS and the configured model is not on the
known-rejecting allowlist (currently text-embedding-ada-002).
The provenance check (was VECTOR_DIMENSIONS explicitly set?) lives as
EmbeddingSettings.resolve_send_dimensions() because it needs access to
model_fields_set, which the standalone resolver does not have. The
resolved boolean is passed into _EmbeddingClient at construction time;
the client never inspects mode or provenance.
Also pins cloudevents <2.0 — 2.0.0 reorganized the package and dropped
cloudevents.conversion and cloudevents.http, which src/telemetry/emitter.py
imports. The original `>=1.12.0` constraint allowed the broken 2.0 resolve.
With the pin, the imports resolve cleanly and the basedpyright warning
cascade (37+ warnings about unknown types) disappears.
Drive-by cleanups (all unnecessary cast/ignore comments flagged by
basedpyright after the cloudevents downgrade):
- vector_store/lancedb.py, tests/conftest.py, and
tests/deriver/test_vector_reconciliation.py — drop dead pyright ignores
- sdks/python/src/honcho/http/{async_,}client.py — drop unnecessary
cast(datetime, ...) (parsedate_to_datetime already returns datetime)
- vector_store/turbopuffer.py — cast(Any, rows) for the upsert_rows
TypedDict that the SDK exposes but our row builder doesn't satisfy
- tests/test_datetime_parsing.py — ignore reportArgumentType on the
test that deliberately passes wrong types to assert raises

Honcho Python SDK
The official Python library for the Honcho conversational memory platform. Honcho provides tools for managing peers, sessions, and conversation context across multi-party interactions, enabling advanced conversational AI applications with persistent memory and theory-of-mind capabilities.
Installation
pip install honcho-ai
Quick Start
from honcho import Honcho
# Initialize client
client = Honcho(api_key="your-api-key")
# Create peers (participants in conversations)
alice = client.peer("alice")
bob = client.peer("bob")
# Create a session for group conversations
session = client.session("conversation-1")
# Add messages to the session
session.add_messages([
alice.message("Hello, Bob!"),
bob.message("Hi Alice, how are you?")
])
# Query conversation context
response = alice.chat("What did Bob say to the user?")
print(response)
Core Concepts
Peers
Peers represent participants in conversations.
# Create peers
assistant = client.peer("assistant")
user = client.peer("user-123")
# Chat with global context
response = user.chat("What did I talk about yesterday?")
# Chat with perspective of another peer
response = user.chat("Does the assistant know my preferences?", target=assistant)
Sessions
Sessions group related conversations and messages:
# Create a session
session = client.session("project-discussion")
# Add peers to session
session.add_peers([alice, bob])
# Add messages
session.add_messages([
alice.message("Let's discuss the project timeline"),
bob.message("I think we need two more weeks")
])
# Get conversation context
context = session.context()
Messages and Context
Retrieve and use conversation history:
# Get messages from a session
messages = session.messages()
# Convert to OpenAI format for further prompting
openai_messages = context.to_openai(assistant="assistant")
# Convert to Anthropic format for further prompting
anthropic_messages = context.to_anthropic(assistant="assistant")
Async Support
The SDK provides async access via the .aio accessor on any instance:
from honcho import Honcho
async def main():
client = Honcho(api_key="your-api-key")
# Async peer and session creation
peer = await client.aio.peer("user-123")
session = await client.aio.session("conversation-1")
# Async chat
response = await peer.aio.chat("What does this user prefer?")
# Async iteration
async for p in client.aio.peers():
print(p.id)
Metadata Management
# Set peer metadata
user.set_metadata({"location": "San Francisco", "preferences": {"theme": "dark"}})
# Session metadata
session.set_metadata({"topic": "project-planning", "priority": "high"})
Multi-Perspective Queries
# Alice's view of what Bob knows
response = alice.chat("Does Bob remember our discussion about the budget?", target=bob)
# Session-specific perspective
response = alice.chat("What does Bob think about this project?",
target=bob,
session=session)
