OpenAI

GPT models remain the reference point for instruction following, tool use and structured output, and the GPT-Image family covers text-to-image generation. Both are available through the same OpenAI-compatible endpoint as every other model on the platform.

When to use it

At $0.20 per 1M input tokens it sits below the catalogue median of $0.69 — a cost-first choice. Best for coding agents and repository-scale edits. Every model here is reachable with the same API key, so trialling it against a stronger sibling costs one line of code.

Code

from openai import OpenAI
client = OpenAI(
  base_url="https://starseaapi.com/v1",
  api_key="sk-your-key"
)
r = client.chat.completions.create(
  model="gpt-5.6-luna",
  messages=[{"role": "user", "content": "Explain prefix caching in one paragraph"}]
)
print(r.choices[0].message.content)
