GLM 5.1 API
GLM 5.1 API.
$0.90/M input, $3.00/M output (FP8). OpenAI-compatible, no contracts, no minimums.
Point your OpenAI SDK at api.getlilac.com/v1 and request zai-org/glm-5.1.
Model pricing
Pay per token. No commitments.
0.58s TTFT on shared warm endpoints. Competitive with aggregator listings at a lower per-token price.
25% off all tokens above 1B/month for 3 months. That is $0.30/M input and $1.50/M output above the threshold.
More models are coming soon and will be added as they go live.
Integration
One base URL change.
Keep the OpenAI SDK and point it at Lilac. Your existing code just works.
from openai import OpenAI
client = OpenAI(
base_url="https://api.openai.com/v1",
api_key="sk_...",
)
response = client.chat.completions.create(
model="openai/gpt-5.4",
messages=[{"role": "user", "content": "Hello!"}],
)
# Same code. Same SDK. Fraction of the price.
Standard OpenAI client — just change the base URL.
Visible pricing. No aggregator markup.
Shared warm endpoints, no cold starts.
