Google vs OpenAI: Token Pricing, Speed & Intelligence
Full comparison of Google and OpenAI — live token pricing, latency, throughput, context window, strengths, weaknesses, and best use cases. Rates sourced from public APIs — verify before use.
Gemini 3.8 Flash — plus Veo 3.1 video, Lyria 3.5 music, and Gemini Omni
Google DeepMind's Gemini 3.x family spans Gemini 3.8 Flash (latest, promotional pricing until Dec 31 2026), Gemini 3.7 Flash, Gemini 3.6 Flash, Gemini 3.5 Flash, and Gemini 3.1 Pro Preview. The platform has expanded far beyond text: Veo 3.1 for video generation, Lyria 3.5 for music generation, Gemini Omni for video generation, and Gemini Embedding 2 for multimodal embeddings. Gemma 4 open-weight models are free via the API. Check the live table for current per-token rates.
OpenAI
GPT-6 Astra, GPT-5.6 Sol/Terra/Luna — plus image, voice, and realtime APIs
OpenAI's September 2026 API lineup spans GPT-6 Astra (flagship frontier), GPT-5.6 Sol (promotional), GPT-5.6 Terra (balanced), and GPT-5.6 Luna (everyday). Beyond text, the platform includes GPT-Image-2.5 (Sunburst and Flare), GPT-Live-1 voice, GPT-Realtime-2.1 for low-latency voice agents, and transcription/translation models. Batch API saves 50% on all models. Check the live table for current per-token rates.

OpenAI FAQs
What are the latest OpenAI models as of 2026?
OpenAI's current lineup includes GPT-6 Astra (flagship frontier), GPT-5.6 Sol (promotional), GPT-5.6 Terra (balanced), and GPT-5.6 Luna (everyday). The o-series reasoning models remain available for complex multi-step tasks. Check the live table or platform.openai.com/docs/pricing for current rates.
How much does the OpenAI API cost?
OpenAI uses tiered per-token pricing across its model lineup. The Batch API cuts all prices by 50% for async workloads, and prompt caching reduces input costs by 50% on eligible requests. Check platform.openai.com/docs/pricing for current rates.
Does OpenAI support prompt caching?
Yes. Prompt caching is available on GPT-6 Astra, GPT-5.6 Sol, and other major models. Cached input tokens are billed at 50% of the standard input price, making long-context and repeated-system-prompt workloads significantly cheaper.
