KeyError: 'claude-opus'

[lsc64]

Originally everything worked but at some point Devon got stuck and wouldn't restart, giving only the following error message (in tui with --debug)

It seems somewhere the model is set to claude-opus but it's expected to be claude-3-5-sonnet (

Devon/devon_agent/agents/conversational_agent.py

Lines 33 to 36 in 2c39a91

	default_models = {
	"gpt4-o": OpenAiModel,
	"claude-3-5-sonnet": AnthropicModel,
	}

)

Even manually adjusting .devon.config as follows

{
  "modelName": "claude-3-5-sonnet"
}

says it would use sonnet, but still gives the same error

╰─$ devon-tui --debug
Using model name: claude-3-5-sonnet

KeyError: 'claude-opus'

@lsc64 you're right. Looks like somewhere in the tui code it didn't update to 3.5 sonnet. Thanks for raising this issue! In the meantime, let me know if the electron app is working for you

It’s the same for the GUI (electron), I just used the TUI for debugging. (Does —debug work with GUI?)

[ObjectJosh]

@lsc64 Hmm... interesting. Have you tried a clean reinstall of both? Haven't gotten this issue with the electron app yet.

[ObjectJosh]

Meaning, clean install of devon_agent since that's one of the common factors rn
