How much does Gemini 3.5 Flash cost on ATP Token?

List rates for Gemini 3.5 Flash (API id gemini-3-5-flash): input $1.50 / output $9.00 per 1M tokens. Billing uses credits (1 USD = 100 credits), debited from the project balance per completed request. There is no monthly platform fee; see Pricing for the minimum top-up.

How do I call Gemini 3.5 Flash via API?

Create a project API key, enable the API id gemini-3-5-flash (not the display name) on that project’s allowlist, point an OpenAI-compatible SDK at https://api.atptoken.ai/v1, and set model to "gemini-3-5-flash". See the Quickstart on this page and the docs.

What are the context and capabilities of Gemini 3.5 Flash?

Vendor documentation lists a context window of about 1,048,576 tokens. Capability flags (thinking, tools, vision) follow the gateway model catalog — treat the catalog visible to your key as operational truth. Vendor: Google.

Who can use Gemini 3.5 Flash on ATP?

Only models on a project’s allowlist can be called with that project’s key (match the API id). Organization → workspace → project governance, per-request logs, and credit budgets are managed in the ATP Console.

Gemini 3.5 Flash

Google

Gemini 3.5 Flash is Google's high-efficiency multimodal workhorse — the generally available Flash tier that Google positions for sustained agentic execution at Flash-tier cost and speed. It is particularly strong at iterative coding cycles, deploying sub-agents at scale, high-volume assistants, and multimodal processing across text, image, video, audio, and PDF inputs. It defaults to medium thinking effort with full support for thinking levels (minimal, low, medium, high) and automatically preserves reasoning across multi-turn conversations, over a documented 1M-token input window with up to 65K output. On ATP Token it is project-allowlisted and billed in credits at the list rates below.

Where it fits

Good fit

Iterative coding cycles, prototyping, and sub-agent fleets
High-volume assistants and extraction on a Flash budget
Multimodal pipelines mixing text, image, video, audio, and PDF inputs
Multi-turn agents that benefit from automatic thought preservation

Usually not ideal

Peak-difficulty reasoning where a Pro-class model is required
Post-January-2025 knowledge without search grounding (documented cutoff)

On ATP

The same governance applies to every model on the gateway:

Project API key — spend and revocation bound to one project
Model allowlist — only enabled models may be called
Credits — 1 USD = 100 credits, debited per completed request
Per-request logs — model, key, project, credits for audit

Cost estimator

A list-price estimate for a month of traffic. Actual spend follows each completed request.
