Frequently asked questions
Can I use o3 for free?
Yes. o3 is available on the Quad Chat Free plan, which needs no credit card and includes 100 monthly credits shared across every model. Larger requests use more credits, and paid plans from $8/month raise the allowance.
What is the context window of o3?
Context windows differ by variant: o3 200K, o3 Mini 200K tokens, according to the model catalog Quad Chat routes through. Files, pasted text and earlier messages all count toward the window.
Does o3 support images, tools and reasoning?
o3 accept images as input; the other variants are text-only. It supports tool calling. It can reason before it answers, with adjustable effort (low, medium and high). You can switch to another model in the same conversation at any time.
Is o3 private in Quad Chat?
o3 runs on the Quad Chat Private Lane, routed to providers under Zero Data Retention terms. Quad Chat does not train models on your conversations, encrypts chats in transit and at rest, and lets you export or delete them at any time.
How much does o3 cost in Quad Chat?
Quad Chat plans have a flat monthly price and draw usage from shared credits, not a per-token bill. The model picker shows an estimate before you send. For reference, the provider's API list price is from $1.10 to $2.00 per million input tokens across variants.
Can I compare o3 with other models?
Yes. Send one prompt to o3 and one or two other models, such as GPT-6.1 Sol, GPT-6 and GPT-5.6, and compare the answers side by side in the same thread. You can also switch models mid-conversation without losing your files or context.
