What is Hex?
Hex is moving its agent out of the notebook and onto programmable surfaces.
Hex ships a fortnightly digest, and the through-line across the last ten is agent reach. The agent now runs from a CLI and API, appears inside Codex, acts as an MCP client against the user's own apps, can search the web, and can see the generative apps it builds. Alongside that, the model layer has become a customer-facing control: a picker, an admin-set default, Auto with visible attribution, and a rotating roster including Fable 5, Kimi K2.7, Claude Opus 5 and GPT-5.6.
What is PySCF?
Quantum chemistry package adding whole method families every release.
PySCF is a Python-based quantum chemistry toolkit, and its release cadence is unusually feature-dense: each version lands multiple new electronic-structure methods rather than polishing existing ones. Recent releases have built out the GW/BSE excited-state stack, k-point RPA for periodic systems, higher-order coupled cluster, and multi-state PDFT with analytical gradients. Platform work runs alongside — Windows DLL compatibility, GPU4PySCF interfacing, and configurable einsum backends.

Hex
6.3ANALYTICS
Hex is moving its agent out of the notebook and onto programmable surfaces.
◆ Current state
Hex ships a fortnightly digest, and the through-line across the last ten is agent reach. The agent now runs from a CLI and API, appears inside Codex, acts as an MCP client against the user's own apps, can search the web, and can see the generative apps it builds. Alongside that, the model layer has become a customer-facing control: a picker, an admin-set default, Auto with visible attribution, and a rotating roster including Fable 5, Kimi K2.7, Claude Opus 5 and GPT-5.6.
◆ Where it's heading
Hex is positioning the agent as a component other systems call rather than a feature users visit. Governance is being built out in parallel — spend limits, credit usage controls, enterprise role-request controls, signed embedding — which is the pattern of a product preparing for programmatic usage it does not directly supervise. The generative-app surface is drifting the same way, from generated output toward editable, brandable, embeddable artifacts.
◆ Prediction
Expect the CLI and API surface to deepen before the notebook UI gains much, with more of Context Studio and app management reachable programmatically, and expect the spend and role controls to keep pace as headless usage grows.
PySCF
2.5ANALYTICS
Quantum chemistry package adding whole method families every release.
◆ Current state
PySCF is a Python-based quantum chemistry toolkit, and its release cadence is unusually feature-dense: each version lands multiple new electronic-structure methods rather than polishing existing ones. Recent releases have built out the GW/BSE excited-state stack, k-point RPA for periodic systems, higher-order coupled cluster, and multi-state PDFT with analytical gradients. Platform work runs alongside — Windows DLL compatibility, GPU4PySCF interfacing, and configurable einsum backends.
◆ Where it's heading
Two arcs are visible. The methods arc is pushing toward periodic (PBC) parity with molecular calculations — PBC GW, PBC RPA, SOC-ECP for PBC DFT, QM/MM for periodic systems all landed in this window. The infrastructure arc is about getting PySCF to run where it previously did not: Windows, GPUs, alternative tensor-contraction backends.
◆ Prediction
The PBC catch-up should continue, since each release closes another gap between molecular and periodic implementations of the same method; the entries do not indicate which gap is next.
