Background

What does this PR do?

This PR will add support for the RedPill API to gain access to top LLM providers without having an account for each service. This PR aims to support the text generation support in the first implementation.

What kind of change is this?

Features (non-breaking change which adds functionality)

Why are we doing this? Any context or related work?

Reason to support RedPill is to reduce the management of multiple LLM API accounts and allow for a seamless approach to use top LLMs interchangeably with a shared memory state.

Documentation changes needed?

Documentation changes would be adding RedPill to the list of Model Providers available to use.

Testing

Executed in developer environment with pnpm dev.

• Logs of calls to the agent found here https://red-pill.ai/shares/dfcf1de5-e7df-449e-a92e-283fcda7dbf8
• Tested with both Open AI and Anthropic models

Where should a reviewer start?

Reviewer can start by requesting a RedPill API Key from me or the Phala Network team. Which is all that is needed before testing.

Detailed testing steps

• Add the RedPill API Key to secret variable
• Add other environment variables for enabled features
• Set the models to use in ./core/src/core/models.ts
• Spin up agent to test live pnpm dev

love this.

Whenever RedPill has support for image and voice generation, I'll add those features. One part i didn't end up changing was the image inspection that uses gpt-4o-mini. The serverUrl uses the openai API & key by default, but if it uses red-pill API, it will also work. I didn't want to break anything unintentionally there, so I didn't put a fix there.

We don't have a good image provider abstraction yet-- badly needed.
