Model Settings

Plandex gives you a number of ways to control the models and models settings used in your plans. Changes to models and model settings are version controlled and can be branched.

models and set-model

You can see the current plan's models and model settings with the models command and change them with the set-model command.

plandex models # show the current AI models and model settings
plandex models available # show all available models
plandex set-model # select from a list of models, model packs, and settings
plandex set-model planner openrouter/anthropic/claude-3.7-sonnet # set the main planner model to Claude Sonnet 3.7 from OpenRouter.ai
plandex set-model builder temperature 0.1 # set the builder model's temperature to 0.1
plandex set-model max-tokens 4000 # set the planner model overall token limit to 4000
plandex set-model max-convo-tokens 20000  # set how large the conversation can grow before Plandex starts using summaries

Model Defaults 

set-model updates model settings for the current plan. If you want to change the default model settings for all new plans, use set-model default.

plandex models default # show the default model settings
plandex set-model default # select from a list of models and settings
plandex set-model default planner openai/gpt-4o # set the default planner model to OpenAI gpt-4o

Model Packs

Instead of changing models for each role one by one, model packs let you switch out all roles at once. It's the recommended way to manage models.

You can list available model packs with model-packs:

plandex model-packs # list all available model packs

You can create your own model packs with model-packs create, list built-in and custom model packs with model-packs, show a specific model pack with model-packs show, update a model pack with model-packs update, and remove custom model packs with model-packs delete.

plandex set-model # select from a list of model packs for the current plan
plandex set-model default # select from a list of model packs to set as the default for all new plans
plandex set-model anthropic-claude-3.5-sonnet-gpt-4o # set the current plan's model pack by name
plandex set-model default Mixtral-8x22b/Mixtral-8x7b/gpt-4o # set the default model pack for all new plans

plandex model-packs # list built-in and custom model packs
plandex model-packs create # create a new custom model pack
plandex model-packs --custom # list only custom model packs
plandex model-packs show # show a specific model pack
plandex model-packs update # update a model pack
plandex model-packs delete # delete a custom model pack

Custom Models

Use models add to add a custom model and use any provider that is compatible with OpenAI, including OpenRouter.ai, Together.ai, Ollama, Replicate, and more.

plandex models add # add a custom model
plandex models available --custom # show all available custom models
plandex models delete # delete a custom model
