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 silx?
silx 3.0 moved its default Qt binding to PySide6 — a migration for everyone embedding it.
silx releases a couple of times a year and reached 3.0.0 in April 2026, which raised the Python floor to 3.10 and switched the default Qt binding to PySide6. The same release reworked the viewer's data views: 3D scatter support, dedicated RGB(A) image views, the composite ImageView split into Plot2dView and ComplexImageView, and NXdata stacks displayed as images. 3.1.0 has since added asinh axis scaling, the twilight colormaps, and dark-theme icons.

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.
silx
2.5ANALYTICS
silx 3.0 moved its default Qt binding to PySide6 — a migration for everyone embedding it.
◆ Current state
silx releases a couple of times a year and reached 3.0.0 in April 2026, which raised the Python floor to 3.10 and switched the default Qt binding to PySide6. The same release reworked the viewer's data views: 3D scatter support, dedicated RGB(A) image views, the composite ImageView split into Plot2dView and ComplexImageView, and NXdata stacks displayed as images. 3.1.0 has since added asinh axis scaling, the twilight colormaps, and dark-theme icons.
◆ Where it's heading
The project is doing a generational refresh of its GUI layer: modern Qt binding, modules broken out of the composite widgets that had accumulated responsibilities, and the theming work that a desktop application needs to look current. Underneath, the recurring fixes are about HDF5 behavior in real facility environments — file locking, NFS refresh, Windows display paths — which is where a synchrotron toolkit actually gets stressed. Feature growth is concentrated in silx view rather than the library API.
◆ Prediction
Expect the 3.1.x line to keep filling in plotting options and theming, with the PySide6 default flushing out binding-specific bugs from downstream applications over the next few releases.
