A methodology for optimizing agent skills

We published our methodology for optimizing agent skills. It treats a skill's text as a hyperparameter and optimizes it. First it generates a synthetic dataset and then uses GEPA as the skill optimizer. The framework is domain agnostic and not tied to any Bauplan-specific construct.

Read the paper and browse the code.

Semantic annotations for models (alpha)

An alpha release adds semantic annotations that describe the inputs and outputs of your models, giving Bauplan, and the agents working on it, a richer understanding of how data flows through a pipeline.

Run logs in your own bucket

Job and run logs are now written to your own cloud bucket and retrieved through pre-signed URLs. This removes the previous 24-hour access limit.

Benchmarking data branching in OLAP systems

In benchmarks against Snowflake and Databricks - adapting Columbia's BranchBench to OLAP - Bauplan creates branches ~100x and ~250x faster, respectively. Our near-instant branch creation lets agents iterate on production data safely and efficiently, running many branches in parallel and looping through them with minimal branch-creation latency.

Read the benchmark post.

Cloudflare R2 support (preview)

A preview integration lets you Cloudflare R2, so you can import Parquet files stored in R2 as zero-copy external tables and run Bauplan pipelines on them.

See the R2 integration docs.

MCP server with OAuth for Claude Desktop

Bauplan's MCP server now supports a standard OAuth flow and works out of the box with Claude Desktop. Connect once and let agents query catalogs, run pipelines, and inspect data. Read about Bauplan's MCP server.

Quick start with bauplan init

A new bauplan init command scaffolds a ready-to-run project: the project config, a sample pipeline with a model and an expectation test, and its Python dependencies. See the quick start guide.

Read Snowflake and BigQuery tables

Bauplan models can now read from Snowflake and BigQuery through a connector, arriving in your Python code as Apache Arrow tables.
See the Snowflake and BigQuery integration docs.

Estuary CDC integration

Stream data from any Estuary source into Bauplan Iceberg tables. The Bauplan materialization connector merges row-level inserts, updates, and deletes in near real-time. See the Estuary integration docs.

BigQuery and GCS integration

Bauplan now works with Google Cloud in two directions: sync a GCS bucket into your lakehouse with AWS DataSync to run pipelines on GCS-landed data, and register Bauplan tables in BigQuery to query them with no data copy (read-only).
See the GCS and BigQuery integration docs.
