OpenAI API Review & Score

GPT-6 and GPT-5.6 API for developers

Editorial score from public sources · Updated Sep 26, 2026

How much does OpenAI API cost?

Per-token pricing, not a flat subscription. GPT-6 Astra: $10/$50 per million input/output tokens. GPT-5.6 Sol: $5/$30; Terra: $2/$12; Luna: $0.20/$1.20 (after an 80% cut on July 30, 2026). Cached input bills at 10% of the standard rate, and the Batch API halves most prices. Check platform.openai.com/pricing for the current table — this pricing moves every few months.

About OpenAI API

The OpenAI API gives developers programmatic access to OpenAI's model lineup for building AI applications. The current flagship is GPT-6 Astra (released September 3, 2026); the GPT-5.6 family (Sol, Terra, and the budget Luna tier) remains generally available and is still the workhorse for most production traffic, alongside DALL-E image generation, Whisper transcription, and TTS voice models. It's the most widely adopted AI API, with extensive documentation, SDKs, and community resources.

Pros & Cons

Pros

Widest selection of AI models (text, image, audio) under one API
Extensive documentation and SDK support
Largest developer community and ecosystem
Aggressive price competition has pushed budget-tier pricing down sharply in 2026

Cons

Pricing and model names change every few months — code and cost estimates need regular review
Token pricing can still get expensive at scale on the flagship tier
Model deprecation can break existing applications when older GPT-5.x models are retired
