PROFILE
Cthomas
Over a 16-month period, contributed extensively to the letta-ai/letta repository, building and evolving a robust multi-agent orchestration platform for AI workflows. Leveraging Python, FastAPI, and SQLAlchemy, delivered features such as asynchronous agent loops, streaming APIs, and advanced observability with OpenTelemetry. The work included deep API design, backend development, and integration of LLM providers, focusing on reliability, scalability, and developer experience. Implemented concurrency-safe workflows, granular logging, and billing-aware telemetry, while modernizing the SDK and strengthening test automation. These efforts improved system throughput, reduced latency, and enabled safer, more auditable automation for multi-tenant, production-grade AI applications.

Mar 1, 2026March 2026 monthly summary for letta-ai/letta: Delivered end-to-end billing visibility and enhanced agent interactions, enabling cost analytics and attribution across telemetry and streaming. Implemented the BillingContext schema and propagated billing metadata through core, adapters, and streaming services, with ClickHouse updates to store billing fields. Extended SleeptimeMultiAgent V3/V4 streaming methods to accept billing_context, enabling end-to-end cost visibility. Launched Agent Direct Messaging Enhancement with agent_id support for default conversations. Completed internal reliability and API hygiene work (billing header propagation, test coverage, OpenAPI/public API boundaries, and SDK regeneration) to support these capabilities. Result: improved business value through cost insight, smarter billing-aware routing, and a stronger platform for billing-driven decision making.

May 1, 2025May 2025 LettA monthly summary focused on delivering business value and technical excellence in letta. Key features delivered include MCP support for sleeptime and BYOK 2.0, with Gemini integration in BYOK. There were substantial strides in async orchestration through a broad migration to asyncify across core paths, enabling higher concurrency and throughput. Observability and tracing were strengthened with user_id included in OpenAI requests and latency insights added to tracing, along with targeted improvements to LLm tracing. Also, notable improvements in traceability and reliability came from adding step IDs in LettA messages and other stability fixes across the stack.
