Tips Pro
Use GPT-4o Mini for simple classification tasks
Reserve GPT-4o for complex reasoning and analysis
Optimize prompts to reduce token counts
Gunakan GPT-4.1 untuk tugasan konteks panjang yang memerlukan sehingga 1M token
Kesilapan Biasa
Not accounting for system prompt tokens
Using wrong model tier pricing assumptions
Lupa bahawa token penaakulan o-series menambah jumlah kos
Menganggap semua model mempunyai tetingkap konteks yang sama
Istilah Utama
GPT-4o: OpenAI flagship multimodal model
GPT-4o Mini: Lightweight cost-effective model
Token: Text unit processed by the model
Context window: Maximum tokens per request
o4-mini/o3: Model yang dioptimumkan untuk penaakulan
Token penaakulan: Token rantai pemikiran dalaman dalam o-series
Konsep Berkaitan
Token Pricing: OpenAI charges per 1,000 tokens, with separate rates for input and output — output tokens cost 3-6x more.
Context Window: The maximum number of tokens a model can process in a single request — GPT-4.1 supports up to 1M tokens.
Reasoning Tokens: Internal chain-of-thought tokens used by o-series models — they don't appear in responses but are charged.
Prompt Caching: Reusing cached prompt prefixes to reduce input token costs for repeated queries.
Model Tiering: Using different models for different task complexity levels to optimize cost.
Contoh
A chatbot sends 1,500 input tokens to GPT-4o and generates 300 output tokens. Cost: (1500/1000 × $0.0025) + (300/1000 × $0.01) = $0.00375 + $0.003 = $0.00675.
Mentafsir Hasil
Focus on output costs first — output tokens are typically 3-6x more expensive than input tokens, so optimizing response length has the biggest impact on total cost. A model that costs twice as much per input token but generates 50% shorter responses may actually be cheaper overall.
Compare models on cost-per-quality, not just cost-per-token. GPT-5.4 Mini is the sweet spot for most production workloads — it delivers 90%+ of GPT-5.5 quality at 85% lower cost. Reserve GPT-5.5 and o3 for tasks where the quality difference directly impacts user experience or business outcomes.
For high-volume applications, the per-request cost difference compounds rapidly. A $0.005 difference per request becomes $5,000/month at 1 million daily requests. Use this calculator to model your specific usage patterns across multiple models before committing to an architecture.
Soalan Lazim
Apa yang baharu dalam siri GPT-5.5?
GPT-5.5 ialah model utama terkini OpenAI dengan penaakulan yang dipertingkat pada $0.005/$0.03 setiap 1K token. GPT-5.4 menawarkan kualiti terkini pada separuh harga ($0.0025/$0.015). GPT-5.4 Mini ($0.00075/$0.0045) dan Nano ($0.0002/$0.00125) meliputi beban kerja pengeluaran dan ringan.
Apakah model penaakulan siri-o?
o4-mini ($0.0011/$0.0044) dan o3 ($0.002/$0.008) ialah model yang dioptimumkan untuk penaakulan oleh OpenAI. Mereka cemerlang dalam matematik, pengekodan, dan logik kompleks — mengenakan caj untuk token penaakulan dan token output yang kelihatan.
Seberapa tepat anggaran kos ini?
Costs are calculated using OpenAI's published API pricing as of 2026. Actual costs may vary based on caching, batching, and special pricing agreements.
Adakah OpenAI mengenakan caj untuk token input dan output?
Ya, OpenAI mengenakan bayaran berasingan untuk token input (prompt) dan token output (pelengkap). Token output biasanya lebih mahal. Model o-series juga mengenakan bayaran untuk token penaakulan dalaman.
