The Problem
With the flurry of new LLMs published almost daily, it may be
confusing for developers to keep track of which exact models are
available through various API services at any given time. When Gemini 3 was released a couple of days ago, I could not find the correct model name for a while (turned out to be "gemini-3-pro-preview")
The Solution
I built (with Claude Code help) a simple CLI app to list available models for the major providers.
Usage
CODE
$ ./llm_models.py -h
usage: llm_models.py [-h] -p {OpenAI,Anthropic,xAI,GoogleAI,VertexAI} [-r REGION]
List available LLM models from various providers
options:
-h, --help show this help message and exit
-p {OpenAI,Anthropic,xAI,GoogleAI,VertexAI}, --provider {OpenAI,Anthropic,xAI,GoogleAI,VertexAI}
The LLM provider backend.
- 'GoogleAI': Google AI Studio (API Key). Global/Auto-routed.
- 'VertexAI': Google Cloud Vertex AI (IAM Auth). Region-specific.
-r REGION, --region REGION
Google Cloud region (e.g., 'us-central1').
*Required* if provider is VertexAI. Ignored for other providers.
$ ./llm_models.py -p Anthropic
Listing available Anthropic models...
