Frequently asked questions
Can I use Mercury 2.5 for free?
Yes. Mercury 2.5 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 Mercury 2.5?
Mercury 2.5 accepts up to 260K tokens of context and can write up to 64K tokens in one reply, according to the model catalog Quad Chat routes through. Files, pasted text and earlier messages all count toward that window.
Does Mercury 2.5 support images, tools and reasoning?
Mercury 2.5 works with text input only; pick a vision model in the same chat when you need to attach images. It supports tool calling. It can reason before it answers, with adjustable effort (instant, low, medium and high). You can switch to another model in the same conversation at any time.
Is Mercury 2.5 private in Quad Chat?
Mercury 2.5 runs on the Standard Lane because no Zero Data Retention route is available for it, so the provider may retain prompts under its own policy. Quad Chat asks you to confirm before first use and never trains models on your chats.
How much does Mercury 2.5 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 $0.04 per million input tokens and $0.15 per million output tokens.
Can I compare Mercury 2.5 with other models?
Yes. Send one prompt to Mercury 2.5 and one or two other models, such as GPT-6.1 Sol, Gemini 3.8 Flash and Claude Opus 5.5, and compare the answers side by side in the same thread. You can also switch models mid-conversation without losing your files or context.
