Grok 4.5 and 4.6, catalog expansions, and the move to nexus-hub.tech¶

The regular Nexus update of September 3 adds the Grok family, expands familiar model lines, moves the service to nexus-hub.tech, and makes the API more reliable.

New capabilities¶

Grok family: 4.5 and 4.6¶

The catalog now has a dedicated Grok family alongside GPT / Codex, Claude, Gemini, DeepSeek, and GLM.
Grok 4.5 and Grok 4.6 are available in the API and in the Telegram bot Models screen.
In API-key settings you can allow the whole Grok family or individual models, just as with the other families.

Expansions in existing families¶

New models are available in families you already use:

Claude Fable 5.1 in the Claude family;
Gemini 3.8 Flash in the Gemini family;
GLM 5.3 Flash in the GLM family;
DeepSeek V4 Flash Vision in the DeepSeek family — a vision-capable option.

See the current list, prices, and routes on the bot Models screen and on Models and prices. The set of models depends on the specific key.

Improvements¶

Move to nexus-hub.tech¶

The canonical service addresses are now:
API: https://api.nexus-hub.tech;
documentation: https://docs.nexus-hub.tech;
status: https://status.nexus-hub.tech.
The previous nexus-hub.ru addresses still work during a transition period.
Please update the base URL in clients, scripts, and bookmarks by 15 October 2026. After that date the old domain will stop working.

Reliability¶

We expanded the Nexus network infrastructure. The service should stay available more consistently and depend less on a single point of failure.
For you this means steadier API, documentation, and status-page access. Keys and settings stay the same except for the address.

Support and documentation¶

The Help and FAQ pages, as well as the documentation footer, now include an extra contact for when the Telegram bot is unavailable. The bot remains the main support channel.
The bot guide lists the Grok family in the same order as the catalog.

Existing API keys, balances, and selected models remain valid. You do not need to reissue a key.
If a client still uses https://api.nexus-hub.ru, change it to https://api.nexus-hub.tech or https://api.nexus-hub.tech/v1, depending on the format the program expects. Do this before 15 October 2026.
To use the new models, open Models in the Nexus Hub bot or request the current catalog for your key.
If Telegram is unavailable, use the contact on the Help page.
If you do not need the new models and your base URL already points to nexus-hub.tech, no further action is required.
