GPT-5.6 Sol

OpenAI GPT-5.6 Sol is available in the Business API catalog.

openai/gpt-5.6-sol

Capabilities

GPT-5.6 Sol is a language model served through the Pika developer API. Send it a list of chat messages and it streams back a text reply, using the OpenAI-compatible chat-completions shape.

Authentication

api key header

The Pika API uses API keys to authenticate requests. Send your key in the X-API-Key header. Your API key is a secret. Don't expose it in browsers or other client-side code. Instead, call the API from your server. The signed-in playground uses a portal session and never sends your API key.

Request

curl -X POST https://api.dev.pika.art/v1/chat/completions \
-H "X-API-Key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "openai/gpt-5.6-sol",
"messages": [
{ "role": "user", "content": "Hello, who are you?" }
]
}'

Pass openai/gpt-5.6-sol as the model and a messages array of { role, content } turns. Set stream: true to receive tokens incrementally over server-sent events.

The Python and TypeScript examples use the official OpenAI SDK with its base URL pointed at https://api.dev.pika.art/v1 — no Pika-specific SDK is needed. Keep your Pika API key and existing OpenAI code works without a rewrite.

Errors

shared across calls

Errors use conventional HTTP status codes with a JSON body of the shape {"message": "..."}. A missing or invalid key returns 401.
