Published 2026-07-20 · NovAI Team

Picking a coding model in 2026 comes down to quality, latency, and cost. Here are the top options — all callable from one OpenAI-compatible endpoint.

Top coding models (per 1M tokens)

Model	Input	Output	Why pick it
kimi-k2.7-code	$1.036	$4.305	Dedicated coding model
kimi-k2.7-code-highspeed	$2.073	$8.61	Lowest latency for IDE/agents
deepseek-v4-pro	$0.503	$1.007	Best price/performance
deepseek-v4-flash	$0.168	$0.336	Cheapest for high volume
doubao-seed-2.0-code	$0.448	$2.24	Cheap code-tuned option

How to choose

Best overall value: DeepSeek V4-Pro — strong coding at a fraction of the cost.
Dedicated coding model: Kimi K2.7 Code; use the highspeed variant for interactive IDE/agent latency (temperature is fixed at 1).
Tightest budget: Doubao-Seed-2.0-Code ($0.448 input) or DeepSeek V4-Flash.

Same code, swap the model

from openai import OpenAI

client = OpenAI(
    api_key="nvai-your-key",
    base_url="https://aiapi-pro.com/v1"
)

resp = client.chat.completions.create(
    model="kimi-k2.7-code",
    messages=[{"role": "user", "content": "Hello!"}]
)
print(resp.choices[0].message.content)
