Overview

ArgentOS supports multiple model providers, allowing you to mix local and cloud models across different tiers. Each provider has its own authentication, endpoint configuration, and model catalog.

Anthropic

Primary provider. Claude Haiku, Sonnet, and Opus.

Ollama

Local open-source models. Zero cost.

MiniMax

Alternative cloud provider with competitive pricing.

OpenRouter

Meta-provider routing to hundreds of models.

​
Anthropic

The primary provider for ArgentOS. Supports Claude Haiku, Sonnet, and Opus.
  • Endpoint: https://api.anthropic.com/v1
  • Auth: API keys (sk-ant-api...) or setup tokens (sk-ant-oat01-...)
  • Models: claude-haiku-4-20250514, claude-sonnet-4-20250514, claude-opus-4-20250514
  • Features: Streaming, tool use, prompt caching (API keys only)
Prompt caching only works with standard API keys, not with Max subscription setup tokens.

​
Ollama (Local)

Run open-source models locally with zero cost.
  • Endpoint: http://localhost:11434
  • Auth: None required
  • Models: Any model available in Ollama (Qwen3, Llama, Mistral, etc.)
  • Default: qwen3:30b-a3b for the LOCAL tier
# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Pull the default local model
ollama pull qwen3:30b-a3b

​
MiniMax

An alternative cloud provider with competitive pricing.
  • Endpoint: https://api.minimax.io/v1 (portal API)
  • Auth: Coding Plan key (sk-cp-...)
  • Models: MiniMax-M2.1 (general), M2-her (roleplay/character), MiniMax-VL-01 (vision)
MiniMax cannot handle mid-session fallback from Anthropic. Tool call history with Anthropic-format IDs (toolu_01...) causes HTTP 400 errors. MiniMax works best for fresh sessions or non-tool conversations.

​
Z.AI

GLM-series models from Zhipu AI.
  • Endpoint: Z.AI API
  • Auth: Z.AI API key
  • Models: GLM-4.7, GLM-4.7-FlashX, GLM-4.7-Flash

​
OpenRouter

A meta-provider that routes to many model providers.
  • Endpoint: https://openrouter.ai/api/v1
  • Auth: OpenRouter API key
  • Models: Access to hundreds of models from multiple providers

​
Provider Configuration

Providers are configured through auth profiles in: 
~/.argentos/agents/main/agent/auth-profiles.json
