OpenAI & ChatGPT
inside Sevantia

Access ChatGPT and all OpenAI models with enterprise features that standalone ChatGPT doesn't offer — multi‑engine workspace, smart file understanding, superior streaming & team governance.

Unlike regular ChatGPT, Sevantia gives you ChatGPT Plus capabilities and more: broader model coverage (reasoning • code • vision • audio • image) with enterprise controls. Seamlessly switch between OpenAI, Anthropic or Gemini based on your specific needs — something standalone ChatGPT can't provide.

Models

Breadth of model families

Access advanced reasoning models, multimodal models (text + vision + audio), lightweight efficient models for cost savings, specialized reasoning engines for deep chain‑of‑thought, plus speech recognition and image generation capabilities.

Interface

Intuitive conversation controls

Navigate your AI workspace effortlessly with intelligent conversation organization, one-click model switching, persistent chat history with automatic naming, contextual helper prompts, and drag-and-drop file processing for images, documents, and audio.

Performance

Ultra-responsive streaming

Experience minimal wait times with rapid first-token delivery, smooth continuous streaming, and resilient connections that maintain flow even during network fluctuations, tab switching, or background use — creating a natural, uninterrupted conversation flow.

Management

Enterprise-grade controls

Gain complete visibility and control with role-based access permissions, customizable system instructions per conversation, adjustable history depth settings, and detailed usage metrics — ensuring predictable costs and consistent experiences across your organization.

Why OpenAI stands out

OpenAI delivers the best balance of versatility and reliability among AI engines. With industry-leading multimodal capabilities, proven reasoning strength, and a well-documented ecosystem, it excels as your primary AI engine. When specialized needs arise—Anthropic for nuanced analytical tasks or Gemini for efficient long-context processing—Sevantia lets you instantly switch without losing your workflow.

Strengths
Industry-leading multimodal processing • Strongest general-purpose reasoning • Most mature ecosystem • Highest developer adoption • Regular feature releases
Ideal For
Code generation, content creation, image analysis, audio transcription, and most everyday AI tasks where balanced performance matters more than extreme specialization.

Why choose OpenAI through Sevantia

Our chat workspace amplifies OpenAI with multi‑engine fallback, attachment synthesis (text extraction, vision analysis, transcription), streaming resiliency & contextual model governance.

Pick fast modes or dive into advanced model selection. Apply dynamic system instructions and tune conversation memory depth to sculpt reasoning. Stop, continue, retry & compare outputs without losing context.

Helper prompts accelerate structured tasks (summaries, refactors, translations) while like / dislike feedback guides quality tracking. Credits ensure predictable spend with optional role gates for premium models.
