Pycharm plugin Continue 1.0.33 error using GPT-5

[stephanerey]

Hi there,

I've installed Continue v1.0.33 on pycharm community 2025.2.0.1 from the plugin manager.
I'm creating an agent connecting to my openai API key. It works fines with GPT-4o.

With GPT-5 I get the error :
400 Unsupported parameter: 'max_tokens' is not supported with this model. Use 'max_completion_tokens' instead.

my assistant YAML file is :

name: Agent
version: 1.0.0
schema: v1

models:

• name: gpt5
  provider: openai
  model: gpt-5
  roles: [chat, edit, apply]
  apiBase: https://api.openai.com/v1
  apiKey: ${{secrets.OPENAI_API_KEY}}

• name: gpt4o_autocomplete
  provider: openai
  model: gpt-4o
  roles: [autocomplete]
  apiBase: https://api.openai.com/v1
  apiKey: ${{secrets.OPENAI_API_KEY}}

contextProviders: [openFiles, gitDiff, repoMap]

Why can't I get the latest v1.4.x from pycharm plugin manager ?
Is it something wrong on my side or just not supported from Continue for PyCharm ?

Thanks & cheers
Stephane
