Pareto 26.9 API on ModelFold
Pareto 26.9 is an earlier release of Unbiased’s Pareto, a multimodal composite model built for research, coding and agentic workflows. Try Pareto 26.9 in the ModelFold Playground, then call it from your own code through an OpenAI-compatible chat completions API.
What Is the Pareto 26.9 API
Pareto 26.9 at a glance
Pareto 26.9 is a chat model from Unbiased. It accepts text and images as input and returns text, with a context window of up to 262K tokens.
Use it without hosting anything
On ModelFold you call Pareto 26.9 with a single API key — no model weights to download and no inference servers to run. The same key also works for the other chat, image, video and audio models on ModelFold.
Core Capabilities of Pareto 26.9
Up to 262K tokens of context
Keep long conversations, large documents and sizeable code in a single request, so the model can reason over the full material instead of fragments.
Understands images
Besides text, Pareto 26.9 accepts images as input, so a single request can combine instructions with visual or other media.
Function calling
Pareto 26.9 supports tool (function) calling: describe your functions in the request and the model returns structured calls your code can run — the basis for agents and integrations.
Structured outputs
Ask for JSON that follows a schema (response_format), which makes extraction, classification and system integrations more reliable.
How to Use Pareto 26.9 on ModelFold
- 1
Step 1: Try it in the Playground
Open the Playground at the top of this page, type a prompt and see how Pareto 26.9 responds before writing any code.
- 2
Step 2: Create an API key
Sign in to ModelFold and create an API key in the console. Keep it secret and send it as a Bearer token.
- 3
Step 3: Send a request
Call POST https://modelfold.ai/v1/chat/completions with "model": "pareto-26-9" and your messages. Existing OpenAI-compatible SDKs work by changing the base URL and key.
- ✓
Step 4: Ship and monitor
Integrate the response into your product and check token usage and spend for every call in the console logs.
What You Can Build with Pareto 26.9
Autonomous agents
Build agents that plan multi-step tasks, call your tools and APIs, and keep working toward a goal across long sessions.
AI coding assistants
Generate, explain, debug and refactor code, review pull requests and work through multi-file changes in developer tools and IDE plugins.
Analysis and complex reasoning
Work through research questions, data interpretation, planning and other problems that need careful step-by-step reasoning.
Screenshot and image understanding
Read screenshots, charts, diagrams and photos alongside text — for UI review, visual QA or turning images into structured data.
