Claude Haiku 4.5 - Starrise AI

Claude Haiku 4.5 is Anthropic’s fastest and most cost-effective model, available through Starrise AI via OpenAI-compatible interface. It responds to everyday tasks with ultra-low latency, making it ideal for high-throughput and latency-sensitive applications.

Key Capabilities

OpenAI-compatible — Drop-in replacement for the OpenAI SDK, no other code changes needed
Ultra-fast response — Optimized for low latency
Cost-effective — Far lower per-token cost than larger models
Streaming — Real-time token streaming via SSE
Capable — Excellent performance on coding, writing, and analysis tasks

Quick Example

curl https://ai.alad.com/v1/messages \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-haiku-4-5",
    "messages": [
      { "role": "user", "content": "Explain quantum entanglement in simple terms." }
    ]
  }'

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://ai.alad.com/v1"
)

response = client.chat.completions.create(
    model="claude-haiku-4-5",
    messages=[
        {"role": "user", "content": "Explain quantum entanglement in simple terms."}
    ]
)

print(response.choices[0].message.content)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://ai.alad.com/v1"
)

stream = client.chat.completions.create(
    model="claude-haiku-4-5",
    messages=[
        {"role": "user", "content": "Write a short poem about the ocean."}
    ],
    stream=True
)

for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")
