Agents

Choose the right agent for your workload. Each agent runs inside an isolated sandbox and connects to your LLM via your API key.

Why Deictic? Recommended

  • Any LLM provider: Use Anthropic, OpenAI, DeepSeek, Google, or any OpenAI-compatible endpoint (e.g., coding67.com, OpenRouter).
  • Custom tools: Define your own tool schemas. The agent will call them during execution.
  • Custom system prompt: Control agent behavior with your own instructions.
  • Model-agnostic: Switch between claude-sonnet-4-5, gpt-4, deepseek-v4-pro, etc. without changing your integration.
