Use Inkling Small from the API

OpenAI-compatible. Same Faceb.ai tokens cover chat and API. Drop-in replacement for the OpenAI SDK.

curl https://api.faceb.ai/v1/chat/completions \
  -H "Authorization: Bearer sk-faceb-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "thinkingmachines/inkling-small",
    "messages": [{"role": "user", "content": "Hello!"}],
    "stream": true
  }'
from openai import OpenAI

client = OpenAI(
    base_url="https://api.faceb.ai/v1",
    api_key="sk-faceb-YOUR_KEY",
)

stream = client.chat.completions.create(
    model="thinkingmachines/inkling-small",
    messages=[{"role": "user", "content": "Hello!"}],
    stream=True,
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="", flush=True)
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.faceb.ai/v1",
  apiKey: "sk-faceb-YOUR_KEY",
});

const stream = await client.chat.completions.create({
  model: "thinkingmachines/inkling-small",
  messages: [{ role: "user", content: "Hello!" }],
  stream: true,
});
for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content || "");
}

Also works for image generation (image-output model slugs return image_url content parts) and web search (add "web_search": true to the payload). Same endpoint, same wallet.

Frequently asked — Inkling Small

What is Inkling Small?

Inkling Small is a chat/completion model served by Thinkingmachines and accessed through Faceb.ai. Try it without signing up — guest users get a small pool of session tokens to experiment.

Is Inkling Small free on Faceb.ai?

You get 30,000 tokens free every day — usually enough for a handful of messages a day on this model. Need more? Pro is $14.99/month for 15M tokens, or top-ups from $5.

What's Inkling Small's context window?

524,288 tokens. Paste your source material in, no need to truncate.

Can I call Inkling Small from the API?

Yes. Any API key from /account/api/ works with model slug `thinkingmachines/inkling-small`. The OpenAI SDK works with base_url=https://api.faceb.ai/v1.

How does Inkling Small compare to GPT-4o or Claude?

Depends on the task. Faceb.ai lets you switch models per message — benchmark side-by-side by asking both the same prompt, which is more reliable than abstract comparisons.

How much does Inkling Small cost per message here?

Around 1,038–2,594 tokens per typical message. 15M Pro tokens buy roughly 5,782–14,450 messages.

Does Faceb.ai train on my Inkling Small prompts?

No. We contractually request that upstream providers not train on content routed through us. Your chat history lives only on your account.

Is Inkling Small good for coding?

It depends on the model size and training mix. For serious code work the developer favourites are Claude 3.5 Sonnet and DeepSeek V3; for quick edits, most capable models work fine.

Can I use Inkling Small on the API with the OpenAI SDK?

Yes — point your SDK at https://api.faceb.ai/v1 and use this model's slug as the model parameter. Everything else works as normal.

Does Inkling Small support image inputs?

Check the model catalog — multimodal models are marked in the picker. If it accepts images, you can drop screenshots and diagrams straight into the chat.

Can I switch from Inkling Small to another model mid-chat?

Yes — the picker is always at the top of the chat. Previous context carries over.

Will newer versions of Inkling Small show up here automatically?

Yes. Our catalog auto-fetches from the upstream aggregator, so provider updates and new versions appear in the picker as soon as they're available.
