Major Nexus update: models, API, and self-service tools¶

The August 15 update brings together changes to the model catalog, API, Telegram bot, top-ups, support, and documentation.

New capabilities¶

DeepSeek and GLM now have dedicated families in the model screens and API-key access settings. They appear alongside GPT / Codex, Claude, and Gemini when they are available to the specific key.
The new GET /v1/catalog returns current public models, usage formats, and final Nexus prices in RUB, USD, EUR, or CNY. The documentation uses the same source for its live price table.
The catalog can publish verified model capabilities for a specific endpoint, including streaming, tools, structured output, penalties, sampling, and other optional parameters. A missing entry remains unknown instead of being treated as automatically unsupported.
Declared context windows for the main model groups and a dedicated parameter matrix are now published so you can check a model and endpoint combination before sending a request.

On the first /start, the bot asks for the interface language and display currency in sequence, then creates the profile and shows its Nexus ID.
More now includes a safe way to move the entire positive available balance between two profiles. Keys, history, settings, and Nexus IDs are not moved.
When Free API trial is shown, a new user can confirm a news-channel subscription and receive a short-lived trial key without opening a support ticket. Leaving the channel revokes that key.

The top-up screen accepts an amount in RUB or the selected display currency and shows only currently available payment methods.
Before opening the payment page, the bot shows the amount, fee, amount-based bonus, promo code, and final balance credit. These values remain attached to that specific payment attempt.
A purchase made without a Nexus ID can be activated with the one-time code or link from the post-payment message.
After activation, the bot shows the paid amount, adjustments, final credit, resulting balance, and the available next steps.

Invite friends now includes a permanent link, invited-user list, progress, and values in the selected display currency. Qualification uses verified paid usage; the free trial and bonus credits do not replace that requirement.
After approval, the partner area provides campaigns, referrals, and reward history. Available actions and terms depend on the completed review; approval is not guaranteed.

A ticket is created from a category and asks only for information relevant to that issue. You can attach a photo or document, review the summary, and continue the saved draft after going back.
My tickets shows status, conversation, attachments, and an unread-event divider. A new user reply can automatically reopen a resolved ticket or one waiting for the user.
After resolution, you can say whether the answer helped, leave an optional rating, and reopen the ticket with a new comment.

The main menu, More, Keys, Models, History, top-up, support, and partner screens now use consistent paths, labels, back buttons, and icons.
Key cards are more compact. Filters preserve the current page, and access to all models, a full family, or one model is saved immediately after selection.
Models is split into family pages and shows IDs, input/output, cache read and write, per-request prices, and supported endpoints. The bot falls back to plain text when rich tables are unavailable.
History shows up to five events per page, separates API and balance events, expands the components of a confirmed charge, and provides a plain-text fallback for clients without rich-table support.
Model prices, key limits, trial balance, and referral values use the selected display currency. Balance storage and calculations remain in RUB.
Dates and custom history ranges now use UTC consistently. Previously stored absolute timestamps are not recalculated.

The public documentation has been rebuilt in English and Russian with a quick start, complete API reference, endpoint list, use cases, help, and search.
Dedicated setup guides now cover Codex CLI, ChatGPT / Codex Desktop, Claude Code, Claude Desktop, VS Code, Zed, T3 Code, CC Switch, Direct API, and custom integrations.
The Privacy Policy and Terms of Service are now published, with links from the bot's main menu and the documentation footer.
The update archive now has permanent English and Russian pages, categories, and tags. Every post separately lists capabilities, improvements, fixes, and compatibility requirements.

Models with the same display position no longer change order between catalog views; ordering is stable inside each family.
Models unavailable to a key no longer appear in public lists. A request for an unavailable model returns a safe error before any charge.
Variants of one model are no longer merged when their prices or usage formats differ, while identical rows are no longer duplicated.

An activated trial balance now uses the selected display currency instead of always showing RUB.
A temporary Telegram failure or unknown subscription status no longer revokes a valid trial. Revocation happens only after a confirmed unsubscribe.
Repeated actions and concurrent /start calls no longer create a second profile, second trial key, or duplicate credit.
Activation, balance-transfer, and invitation links remain available until language and currency selection is complete, then continue automatically.

Back buttons and duplicate transitions were fixed across support, referrals, language and currency selection, balance transfer, and model settings.
Stored structure markers from a guided ticket no longer appear in the user card; the localized category is shown once as readable text.
History details are split into separate lines again, and the current filter and page are preserved after opening an event or key card.
The status page's light theme no longer inherits a dark background and text; both palettes now use their own styling.

Existing API keys and base URLs for OpenAI-, Anthropic-, and Gemini-compatible clients remain valid; keys do not need to be reissued.
Continue using GET /v1/models with the actual key when selecting a model. Use GET /v1/catalog when the application also needs prices and verified parameter capabilities.
Account for UTC when entering a custom history range or comparing event timestamps.
Review the full amount, fee, bonuses, and final credit before paying. An already created payment attempt keeps its own terms.
Use the API reference, client guides, and Telegram bot guide for setup and diagnostics.
If you do not need the new capabilities, no mandatory action is required after the update.
