Google Gemini Flash Latest is one of Google's models. Put "~google/gemini-flash-latest" in the model field and the rest of your code stays as it is. Google Gemini Flash Latest keeps 1,048,576 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 65,536 tokens. On price it sits in the "mid-range" band — cheaper than 257 and dearer than 149 of the other paid models in the catalogue.
What it can do beyond plain text: it reads images directly, which makes it a real option for invoices, forms and screenshots; it takes files such as PDFs as input; it accepts audio input; it supports tool calling, so it can invoke your own functions with valid arguments; it returns schema-valid JSON through response_format, ready to hand to your code; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.
Pricing is 217,594 toman per 1M input tokens and 1,087,969 per 1M output tokens. A 1,000-word round trip on Google Gemini Flash Latest lands near 1,697 toman. It supports cached input: repeated context is billed at 21,759 toman per 1M, which matters a lot if your system prompt is long. Each input image is billed separately at about 0.22 toman. You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.
The closest alternative with the same capabilities from a different provider is Mistral Medium 3.5 (batch): Google Gemini Flash Latest works out roughly 1× more expensive, and its context window is larger. Both run on the same key and the same code, so trying the other one is a single string change.
To make the figure concrete: 100,000 toman of credit buys roughly 59 thousand-word requests on Google Gemini Flash Latest, and every 1,000 toman is about 589 words of round trip. A job with one million input tokens and one million output tokens comes to 1,305,563 toman in total. Filling this model's 1,048,576-token window costs 228,164 toman on the input side alone, which is the real reason to keep conversation history short.
Its nearest relative in the catalogue is "google/gemini-3.6-flash", and choosing between those two is where most people hesitate. Both land at nearly the same price on a thousand-word request (1,697 and 1,697 toman).
Google has 45 models in our catalogue; the cheapest is Gemma 3 4B at 57 toman per thousand words and the dearest Google Gemini Pro Latest at 5,280. Among the less common parameters it accepts reasoning_effort — all through the standard request body. By context size the nearest option from another provider is DeepSeek V4 Flash 0423 at 1,048,576 tokens.
Good fits: product chatbots and internal assistants, where cost and quality have to balance, logic puzzles and code review, pulling text and fields out of images, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
This model always redirects to the latest model in the Google Gemini Flash family.
