Models

Cyclops Code uses LiteLLM to call any model. Switch providers by changing one string and setting the matching API key.

Providers

Anthropic

export ANTHROPIC_API_KEY="sk-ant-..."
cyclops --model anthropic/claude-opus-4-5
cyclops --model anthropic/claude-haiku-4-5-20251001

OpenAI

export OPENAI_API_KEY="sk-..."
cyclops --model gpt-4o
cyclops --model gpt-4o-mini

Groq

Groq offers a generous free tier and fast inference.

export GROQ_API_KEY="gsk_..."
cyclops --model groq/llama-3.3-70b-versatile
cyclops --model groq/llama-3.1-8b-instant

Google Gemini

export GEMINI_API_KEY="..."
cyclops --model gemini/gemini-2.0-flash
cyclops --model gemini/gemini-1.5-pro

Ollama (local)

No API key needed. Install Ollama, pull a model, then run:

ollama pull qwen2.5-coder:7b
cyclops --model ollama/qwen2.5-coder:7b

Good models for coding tasks: qwen2.5-coder:7b, qwen2.5-coder:14b, deepseek-coder-v2.

Together AI

export TOGETHERAI_API_KEY="..."
cyclops --model together_ai/meta-llama/Meta-Llama-3.1-70B-Instruct-Turbo

Switching models

Pass --model on any invocation to override the default for that run:

cyclops --model gpt-4o "review this PR"

Switch mid-session with /model in the REPL. Type the model name or use the interactive picker with search and autocomplete.

Setting a default

The default model is stored in ~/.cyclops/config.json:

{
  "model": "anthropic/claude-haiku-4-5-20251001"
}

On first launch Cyclops Code will prompt you to pick a default.

Model strings

LiteLLM model strings follow the pattern provider/model-name. See the LiteLLM provider docs for the full list of supported models and their string formats.
