Gemini API support, new models, streaming, and public status page

This major Nexus API release significantly broadens the ecosystem of supported protocols: introducing native Gemini API compatibility, new GPT-5.6 and Gemini 3 model lines, streaming for Chat Completions, connection stability standards, and a public service status page.

New capabilities

Native Gemini API support and model family

  • Added native Gemini API endpoints: text generation (POST /v1beta/models/{model}:generateContent), stream generation (POST /v1beta/models/{model}:streamGenerateContent), token counting (POST /v1beta/models/{model}:countTokens), and model discovery via GET /v1beta/models and GET /v1beta/models/{model}.
  • Added the Gemini model family to the catalog and Telegram bot: Gemini 3 Flash, Gemini 3.5 Flash, Gemini 3.1 Pro Preview, and Gemini 3.1 Flash Image Preview.
  • Grouped the Gemini family in the Models menu and key permission settings.

New OpenAI-compatible models and streaming

  • Added next-generation flagship models: GPT-5.6 Luna, GPT-5.6 Terra, and GPT-5.6 Sol.
  • Implemented real-time Server-Sent Events (SSE) streaming support for POST /v1/chat/completions, enabling token-by-token streaming responses.
  • Added support for Legacy Completions (POST /v1/completions) and compact chat aliases for integration with older development tools.
  • Added a direct single-model lookup endpoint: GET /v1/models/{model_id}.

Public service status page

  • Launched the official status page at status.nexus-hub.tech monitoring latency and availability across all supported endpoints.
  • Added a direct button in the Telegram bot main menu to inspect service health.

Connection stability and standardized error handling

  • Established long-running connection policies: graceful handling of pauses between streaming chunks to prevent false timeouts.
  • Safe client disconnect handling: early connection drops do not leave dangling resources or trigger incorrect balance deductions.
  • Standardized JSON error response envelopes with a unique request_id for efficient support diagnostics.

Improvements

Price reductions and bonus credits

  • Implemented an across-the-board 5–15% base rate reduction for major models.
  • Automatically credited bonus balances to users registered prior to the release.
  • Streamlined bot price tables: hidden unpriced companion endpoints and consolidated multi-endpoint models into clean single rows.

Developer tooling compatibility

  • Improved compatibility for developer tools: Codex CLI, Claude Code, VS Code, Zed, JetBrains, OpenCode, and custom AI agents.

Fixed issues

API and protocols

  • Fixed empty responses and format discrepancies in Legacy Completions and compact model responses.
  • Stopped forwarding client User-Agent headers to preserve client environment privacy.
  • Fixed token usage reporting in Chat Completions streaming mode.

Catalog and bot interface

  • Fixed non-deterministic model sorting during concurrent catalog requests.
  • Fixed keyboard button bindings for the status page in the Telegram bot.

Compatibility and user actions

  • Existing API keys and base URLs remain fully compatible with all new features; no key reissuance is needed.
  • To connect tools to the Gemini API, use the standard /v1beta/ base URLs and endpoints with your Nexus Hub API key.
  • Review the API reference and client setup guides for configuration details.
