I tried to run the first LLM example “Your first LLM agent” in LiveBook. Firstly I got a weird Setup block:

Mix.install([
  {{mix_dep:jido}},
  {{mix_dep:jido_ai}},
  {{mix_dep:req_llm}}
])

which I could easily sort out. I set my OpenAI API key as directed as a secret in LiveBook which the block reported true as expected. However when I tried to run the “Ask the Agent” block I get the following;

10:49:25.330 [warning] Jido.AI.Reasoning.ReAct using ephemeral token secret (no configured :react_token_secret); checkpoint tokens expire on VM restart

No idea why its using Claude/Anthropic? Apart from if I do the following in the LiveBook;

Jido.AI.model_aliases()

it returns

%{
  image: "openai:gpt-image-1",
  thinking: "anthropic:claude-sonnet-4-20250514",
  embedding: "openai:text-embedding-3-small",
  reasoning: "anthropic:claude-sonnet-4-20250514",
  planning: "anthropic:claude-sonnet-4-20250514",
  fast: "anthropic:claude-haiku-4-5",
  capable: "anthropic:claude-sonnet-4-20250514"
}

which shows :fast as configured to be "anthropic:claude-haiku-4-5"

What am I doing wrong?

Thanks in advance
