Psi4 vs Sanity

Psi4 vs Sanity: at a glance
What is Psi4?
Psi4 is closing the gap with ORCA on the methods that decide which code a lab installs
Psi4 ships a major version roughly annually with a trail of conda-compatibility patch releases behind each one. The 1.11 cycle is the most competitively pointed in the window: DLPNO-CCSD and DLPNO-CCSD(T) become callable methods, with cutoffs deliberately tuned to match ORCA, and ZORA arrives for scalar-relativistic core Hamiltonians. Around the science, the project spends heavily on Python-ecosystem plumbing — QCSchema v2, Python 3.14 support, and the QCArchive dependency chain that most of its patch releases exist to unbreak.
What is Sanity?
Studio stops being a plugin host and starts being an SDK host.
Sanity ships from many independently versioned packages into one feed: Studio across three live major branches (4.x, 5.x, 6.x), Media Library on date-stamped releases, the MCP server, and the JavaScript client. The last two weeks are consolidation rather than new surface area. Studio 6.10.0 now provides the App SDK out of the box so custom tools call @sanity/sdk-react hooks without wiring their own providers, while the CLI picks up asset uploads and token expiry dates.

Psi4 is closing the gap with ORCA on the methods that decide which code a lab installs
◆ Current state
Psi4 ships a major version roughly annually with a trail of conda-compatibility patch releases behind each one. The 1.11 cycle is the most competitively pointed in the window: DLPNO-CCSD and DLPNO-CCSD(T) become callable methods, with cutoffs deliberately tuned to match ORCA, and ZORA arrives for scalar-relativistic core Hamiltonians. Around the science, the project spends heavily on Python-ecosystem plumbing — QCSchema v2, Python 3.14 support, and the QCArchive dependency chain that most of its patch releases exist to unbreak.
◆ Where it's heading
Two things are being built at once. Scientifically, the code is filling in the local-correlation and relativistic methods that users otherwise leave for commercial packages, plus external-potential and embedding machinery that makes Psi4 usable as a QM engine inside larger workflows. Structurally, it is betting on the QCArchive stack — qcelemental, qcengine, qcmanybody, optking, qcfractal — which delivers interoperability but also means a Python packaging change downstream can force a release, as 1.10.1 and 1.10.2 both did.
◆ Prediction
The DLPNO work landed as energies only, so analytic gradients for DLPNO-CCSD are the natural next step. Expect at least one more 1.11.x patch driven by the QCFractal and pydantic constraints that the 1.11 notes flag as still unresolved for Python 3.14.
Sanity

Studio stops being a plugin host and starts being an SDK host.
◆ Current state
Sanity ships from many independently versioned packages into one feed: Studio across three live major branches (4.x, 5.x, 6.x), Media Library on date-stamped releases, the MCP server, and the JavaScript client. The last two weeks are consolidation rather than new surface area. Studio 6.10.0 now provides the App SDK out of the box so custom tools call @sanity/sdk-react hooks without wiring their own providers, while the CLI picks up asset uploads and token expiry dates.
◆ Where it's heading
Two tracks run in parallel. One is a housekeeping migration - ESM-only packages, Node 22.12 floors, and the same bugfix backported across 4.x and 5.x in the same afternoon - which is cost being paid down, not capability being added. The other is the agent surface: the MCP server keeps accreting tools, moving from project administration to content operations with asset upload and schema discovery. The Studio/SDK merge points at a single data layer under both custom Studio tools and standalone Sanity apps.
◆ Prediction
Expect the MCP server to keep adding tools at roughly one release a week, and the App SDK integration to shed its listed limitations - the single shared workspace instance and unregistered named multi-resource lookups are called out as known gaps rather than design choices.
