  • Fine-tuning on your data with one click.
  • Realtime voice and vision via API.

Picture this: You upload customer transcripts. OpenAI builds a support agent in hours. No PhD required.

But it’s not perfect. Vendor lock-in bites if you outgrow it.

Pros: Blazing fast iteration. Massive model quality. Global edge network for low latency.

Cons: Costs spike at scale—$20 per million tokens for GPT-4o. Limited governance for regulated industries.

Pricing: Pay-per-token. Starts free, scales to enterprise volume discounts. Expect $0.005–$0.06 per 1K tokens.

Choose OpenAI if you’re a startup racing to MVP. 70% of new AI apps start here, per Gartner 2026 data.

Here’s the thing most miss. Pair it with Vercel for frontend deployment. Instant magic.
