API Configuration

Set up AI model API keys in SoloEnt

Configure API keys to enable SoloEnt’s AI writing features.

What is an API key?

An API key is your authentication credential for accessing AI models. It looks like a random string:

sk-abc123xyz456def789ghi012jkl345mno678pqr901stu234

Important: API access is billed separately from monthly subscriptions. A $20 subscription doesn’t include API usage.

Configuration types

Standard (official providers)

API Key: sk-abc123xyz456...

OpenAI-compatible (third-party)

Most third-party providers need all three fields:

base_url · string · required

API endpoint URL (e.g., https://api.provider.com/v1)

api_key · string · required

Your API key

model_id · string · required

Model identifier (e.g., gpt-4-turbo)

All three fields are required. Confirm with your provider before purchasing.

Advanced: Different models per mode

Configure separate models for Plan and Act modes (optional):

Plan Mode models

Best for strategic thinking:

• Claude Sonnet-4.6
• GPT-5.2
• GLM-5

Act Mode models

Best for execution:

• Gemini Flash (fast)
• DeepSeek (economical)
• Kimi-K2.5 (long context)

Using the same model for both modes is fine for most users.
