Novita alternative: same open models, price per million tokens

Synap402 is an OpenAI-compatible API for open-weight models. Point any OpenAI SDK at https://synap402.com/v1, start on the free tier, no card, then pay per token from credits, or pay per call in USDC with x402 and no account.

On every model on this page, Synap402 lists a lower input price and a lower output price than Novita in the index generated 2026-11-15 04:24 UTC.

Context windows differ: Synap402 has the smaller context window on 2 of 2 (Gemma 4 26B and Qwen3 VL 30B). Check the Context column before you switch a long-context workload.

USD per 1M tokens, list prices. Novita's row per model is its cheapest endpoint listed in the OpenRouter endpoints API; Synap402's is read from /v1/models, which is what the gateway bills. Cached-input, batch and volume discounts are not compared. Index generated 2026-11-15 04:24 UTC; data: price-index.json (CC BY 4.0). Every provider for each model: compare.

How to switch

Change two things in your OpenAI-compatible client: the base URL and the API key. Then use the Synap402 model id.

from openai import OpenAI

client = OpenAI(
    base_url="https://synap402.com/v1",     # was your current provider's base URL
    api_key="sk-pool-...",                  # your Synap402 API key
)
r = client.chat.completions.create(
    model="gemma-4-26b-a4b-it",
    messages=[{"role": "user", "content": "Hello"}],
)
print(r.choices[0].message.content)

Synap402 model ids for the models on this page, as /v1/models lists them:

• gemma-4-26b-a4b-it
• qwen/qwen3-vl-30b-a3b-instruct
