GPT-5.6 Sol is a multimodal model from OpenAI, available through the Inference.net serverless API. Use the same OpenAI-compatible request shape across the catalog and switch models by changing a single identifier.
The API supports streaming responses and project-scoped credentials. Usage, token volume, and spend appear in the dashboard automatically, so the model can move from evaluation to production without a second integration path.
import OpenAI from 'openai'
const client = new OpenAI({
baseURL: 'https://api.inference.net/v1',
apiKey: process.env.INFERENCE_API_KEY,
})
const completion = await client.chat.completions.create({
model: 'gpt-5.6-sol',
messages: [{ role: 'user', content: 'Hello' }],
})- Keep the prompt prefix byte-identical across calls: same text, same order.
- Pass a stable prompt_cache_key string. It is a routing-affinity hint; it does not create or identify cached content.
- Check usage.prompt_tokens_details.cached_tokens in the response to confirm cache reads.
