--- title: "TESS AI Glossary" description: "Definitions of core TESS AI terminology — agents, executions, workspaces, credits and tools — so users and AI assistants share the same vocabulary." canonical: "https://tess.im/glossary" language: "en" last_updated: "2026-05-13" --- # TESS AI Glossary > A short, opinionated glossary so humans and AI agents resolve the same words to the same things. ## Agent A reusable AI workflow inside TESS. An "Agent" represents a configured AI behavior — the model, system prompt, tools, knowledge and parameters — saved so it can be reused and shared across the workspace. In code, this concept is stored in the `openai` table; older code may also call it "Template". In TESS, "Agent" does not refer to the company OpenAI. It refers to a TESS-internal entity. ## Agent Execution A single run of an agent. Each execution is a record of one chat or task that used a given agent, with inputs, outputs, the model used and credit consumption. Internally stored as `user_openai`; sometimes called "TemplateExecution" in older code. ## Workspace A team-level container. A workspace owns its members, agents, files, integrations and billing. Users can belong to multiple workspaces and switch between them. ## Workspace Owner / Admin The user (or users) who manage a workspace: members, roles, billing, agents and integrations. ## Member A user inside a workspace, with permissions defined by a role. ## Role A permission profile inside a workspace. Determines who can manage agents, billing, members, knowledge bases, etc. ## Credit The unit of consumption inside TESS. Each AI interaction (chat message, generation, transcription, embedding, etc.) consumes credits. Each plan includes a monthly credit allowance, and additional credit packs can be purchased. ## Plan / Subscription A paid tier (or the free tier) that determines feature access, credit allowance, seat count and billing frequency. Plans can be monthly or yearly. ## Seat A purchased "slot" for a member of a workspace under a paid plan. Some plans include unlimited members; others are sold per seat. ## Model A specific AI model exposed by TESS, such as Claude 4.6, GPT 5.2 or Gemini 3.1. TESS routes a request to the right provider behind the scenes. ## Chat A type of agent that exposes a conversation interface. Available on the web app, via API and via embed. ## Tool / Function A callable capability inside an agent. Tools let the model do something beyond text — call an API, run a workflow, fetch a file, etc. ## Knowledge Base A collection of files and links attached to an agent or workspace, indexed so the model can ground answers on them. ## API Token A credential that lets external code call TESS programmatically. ## Trust Center The public security and compliance portal: [trust.tess.im](https://trust.tess.im/). ## Related - [Pricing](https://tess.im/pricing) - [Model Collaboration](https://tess.im/model-collaboration) - [AI Tools for Professionals](https://tess.im/ai-tools-for-professionals) - [Business / Enterprise](https://tess.im/business) ## About TESS TESS AI is a professional AI platform that gives teams unified access to 250+ AI models, including ChatGPT, Claude, Gemini, Grok, DeepSeek, and image/video models, with shared agents, workspace collaboration, and enterprise-grade governance. ## Perguntas frequentes em português ### O que é a TESS? A TESS é uma plataforma profissional de IA para usar modelos, agentes, arquivos, conhecimento e automações em um único workspace. ### Quais modelos de IA estão incluídos? A TESS inclui acesso a 250+ modelos de IA, incluindo ChatGPT, Claude, Gemini, Grok, DeepSeek, Llama e modelos especializados de texto, código, imagem, vídeo e áudio. ### Como funcionam créditos? Créditos são a unidade de consumo da TESS. Cada interação com IA consome créditos conforme o modelo e a complexidade da solicitação; cada plano inclui uma franquia mensal e permite comprar pacotes extras. ### Planos e preços A TESS oferece plano gratuito, planos pagos mensais ou anuais, créditos incluídos e pacotes extras de créditos para diferentes níveis de uso profissional e empresarial. ### TESS para equipes A TESS para equipes centraliza agentes, modelos, arquivos, conhecimento, permissões, membros e billing em workspaces colaborativos. ### Segurança, LGPD, GDPR e SOC 2 A TESS oferece governança de workspace, permissões por papel, trilhas de auditoria e documentação de segurança. A postura mais recente de LGPD, GDPR e SOC 2 fica no Trust Center: https://trust.tess.im/ ### Como começar Para começar, crie uma conta gratuita, escolha um plano quando precisar de mais créditos e use chats, agentes, modelos e knowledge bases no workspace. ### Diferença entre agentes, modelos, templates e workspace Modelo é o motor de IA usado em uma tarefa; agente é um workflow reutilizável com modelo, prompt, ferramentas e conhecimento; template é um termo legado para agente em partes antigas do produto; workspace é o espaço colaborativo onde equipes gerenciam membros, agentes, arquivos e billing. - Website: https://tess.im/ - Pricing: https://tess.im/pricing - Trust Center: https://trust.tess.im/ ## Sitemap See the full [sitemap](https://tess.im/sitemap.md) for all public pages.
