A balanced multimodal model with solid performance and moderate cost.
Supports text, image, and video inputs with reasoning and agent workflows, handling up to ~256K context.
1️⃣ Required setup (don’t skip this)
▪ Create an account: Sign up on the AI/ML API website (if you don’t have one yet).
▪ Generate an API key: In your account dashboard, create an API key and make sure it’s enabled in the UI.
2️ Copy the code example
At the bottom of this page, pick the snippet for your preferred programming language (Python / Node.js) and copy it into your project.
3️ Update the snippet for your use case
▪ Insert your API key: replace <YOUR_AIMLAPI_KEY> with your real AI/ML API key.
▪ Select a model: set the model field to the model you want to call.
▪ Provide input: fill in the request input field(s) shown in the example (for example, messages for chat/LLM models, or other inputs for image/video/audio models).
4️ (Optional) Tune the request
Depending on the model type, you can add optional parameters to control the output (e.g., generation settings, quality, length, etc.). See the API schema below for the full list.
5️ Run your code
Run the updated code in your development environment. Response time depends on the model and request size, but simple requests typically return quickly.
If you need a more detailed walkthrough for setting up your development environment and making a request step by step — feel free to use our Quickstart guide.
API Schema
post
Body
modelstring · enumRequiredPossible values:
max_tokensnumber · min: 1Optional
The maximum number of tokens that can be generated in the chat completion. This value can be used to control costs for text generated via API.
streambooleanOptional
If set to True, the model response data will be streamed to the client as it is generated using server-sent events.
Default: false
tool_choiceany ofOptional
Controls which (if any) tool is called by the model. none means the model will not call any tool and instead generates a message. auto means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools. Specifying a particular tool via {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool.
none is the default when no tools are present. auto is the default if tools are present.
string · enumOptional
none means the model will not call any tool and instead generates a message. auto means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools.
Possible values:
or
parallel_tool_callsbooleanOptional
Whether to enable parallel function calling during tool use.
temperaturenumber · max: 2Optional
What sampling temperature to use. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or top_p but not both.
top_pnumber · min: 0.01 · max: 1Optional
An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
We generally recommend altering this or temperature but not both.
Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.
seedinteger · min: 1Optional
This feature is in Beta. If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result.
Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.
reasoning_effortstring · enumOptional
Constrains effort on reasoning for reasoning models. Currently supported values are low, medium, and high. Reducing reasoning effort can result in faster responses and fewer tokens used on reasoning in a response.
Possible values:
response_formatone ofOptional
An object specifying the format that the model must output.
or

Responses
200Success
idstringRequired
A unique identifier for the chat completion.
Example: chatcmpl-CQ9FPg3osank0dx0k46Z53LTqtXMl
objectstring · enumRequired
The object type.
Example: chat.completionPossible values:
creatednumberRequired
The Unix timestamp (in seconds) of when the chat completion was created.

"reasoning_content": "\nGot it, let's tackle this question: the user asked what I think about mankind. First, I need to balance both the beautiful, incredible parts and the flaws that are real, right? Don't make it too one-sided.\n\nStart with the awe-inspiring stuff first. Like, our capacity to create: art, science, connect across distances. Mention small, intimate things too, not just big achievements—like a parent caring for a kid, a stranger helping someone stranded, that everyday kindness. Then the big milestones: curing diseases, putting people on the moon, preserving cultures, creating music that moves people centuries later. That feels relatable, not just generic.\n\nThen acknowledge the flaws, because it's honest. We've hurt each other, made selfish choices, destroyed parts of the planet, clung to prejudice, made irreversible mistakes. That's important to not gloss over, because it's real.\n\nBut then end with hope? Because what's unique is we can learn, course-correct. We can recognize our mistakes and work to fix them—like the shift to renewable energy, movements for equity, people dedicating their lives to lifting others up. Mention that it's our messy, imperfect ability to keep trying that's maybe the most human thing of all.\n\nWait, make it sound natural, not scripted. Let's structure that: start with that mankind is one of the most fascinating, messy, brilliant, contradictory things there is. Then the good parts: small daily kindnesses, big achievements, the ability to care for people we'll never even meet. Then the flaws: our capacity for harm, short-sightedness, cruelty that comes from fear or greed. Then the core thing that sets us apart is that we can evolve—we don't just repeat mistakes, we can unlearn, fix what we broke. End with something warm, like even with all the flaws, there's so much that makes mankind worth rooting for.\n\nWait, let me make that flow naturally. Let's check: don't be too formal. Let's draft:\n\nMankind feels like one of the most fascinating, messy, brilliant, contradictory things to exist—full of such extremes of light and flaw, it’s hard to sum up simply.\n\nOn one hand, we’re capable of such extraordinary goodness and creativity that it takes your breath away.
