DeepSeek

DeepSeek models are the default choice for high-volume workloads: strong reasoning, long context and a price point that makes them viable as an always-on backbone. On StarSeaAPI every DeepSeek variant is served through multiple independent upstream routes, so a single provider incident does not take the model offline.

When to use it

At $0.15 per 1M input tokens it sits far 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="deepseek-v4-flash-0731",
  messages=[{"role": "user", "content": "Explain prefix caching in one paragraph"}]
)
print(r.choices[0].message.content)
