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.
2026¶
API behavior is more consistent and pricing is clearer
This update makes API contracts more predictable for OpenAI-, Anthropic-, and Gemini-compatible clients and clarifies how a request and its usage are handled.
Long support histories open reliably
Long support requests now open reliably: message and status history is split into pages and no longer runs into Telegram's message-length limit.
Anthropic cache prices are calculated correctly
We corrected the price calculation for POST /v1/messages with Anthropic
prompt caching so response usage, history, and the final debit agree.
Broader API compatibility and model catalog
This major Nexus API release adds model families, expands compatible-client scenarios, and improves the handling of long-running requests.
Model availability and prices display correctly
This urgent fix synchronizes the API, Telegram bot, and documentation catalog so you see only models and prices that your key can actually use.
Claude compatibility and model access restored
This urgent correction restored requests after the previous update and synchronized the available-model view in the API and Telegram bot.
More self-service tools and notifications
This update gives you more control over the account and makes daily API work more transparent: key access can be narrowed, and important balance events are visible without manual checks.
More account actions in Telegram
The Telegram bot became a fuller Nexus account area: actions that previously needed manual help are now available in one conversation.
Clearer model prices in the bot
We redesigned the model screen in the Telegram bot so you can compare available models and their prices before connecting a project, without scanning a long list of technical identifiers.
