Perceptron Mk1
Perceptron Mk1 is Perceptron's highest‑quality proprietary vision‑language model focused on video understanding and embodied visual reasoning.
What is Perceptron Mk1?
Perceptron Mk1 is a closed-source vision-language model from Perceptron designed for image and video understanding, OCR, object detection, document parsing, and embodied visual reasoning. It is mainly used for tasks like video question answering, summarization, event and temporal segment detection, and detailed scene analysis across robotics, autonomous systems, surveillance, and AR applications. It also supports structured outputs such as spatial annotations (points, boxes, polygons) and temporal clips for production APIs that need precise localization and grounding in complex visual data. Perceptron Mk1 is the first and highest-quality model in the proprietary Perceptron Mk family of multimodal vision and reasoning models.
Providers
Different companies host the same model. OpenRouter routes your request to one of them based on the routing mode you pick — Balanced (price + speed), Nitro (fastest), or Exacto (highest tool-calling accuracy).
| Provider | Input | Output | Cache read /M | Latency | Throughput | Uptime |
|---|---|---|---|---|---|---|
| Perceptron | ~$0.45 | ~$0.45 | — | ~220ms | ~60 tps | ~99.9% |
| OpenAI | ~$0.50 | ~$0.50 | — | ~250ms | ~80 tps | 99.06% |
| Anthropic | ~$0.55 | ~$0.55 | — | ~260ms | ~70 tps | 99.28% |
| Azure AI | ~$0.52 | ~$0.52 | — | ~240ms | ~75 tps | 100.00% |

Code snippet
Call the model through the OpenAI-compatible API.
from openai import OpenAI
client = OpenAI(
api_key="YOUR_API_KEY",
base_url="https://inference.example.com/v1"
)
response = client.chat.completions.create(
model="perceptron/perceptron-mk1",
messages=[
{
"role": "user",
"content": "Describe this image in one sentence."
}
],
)
print(response.to_json())
{
"model": "perceptron/perceptron-mk1",
"messages": [
{
"role": "user",
"content": "Describe this image in one sentence."
}
]

5 Core Capabilities
-
Conversational Chat
Engages in multi-turn text conversations, following instructions, answering questions, and adapting responses to user context and intent.
-
Image Analysis
Interprets visual content in images, identifying objects, scenes, relationships, and other salient details to support downstream reasoning tasks.
-
Text Translation
Translates written text between multiple languages while preserving meaning, tone, and basic formatting across diverse domains and styles.
-
Screen Content Handling
Processes user interface or webpage-like content, enabling reasoning about layouts, elements, and on-screen information for digital tasks.
-
Optical Character Recognition
Extracts machine-readable text from images, screenshots, or scanned documents to enable search, editing, or further automated processing.

Why Build on LLM.API?
One unified API. Every major model. Built-in reliability, cost control, and observability.
-
Intelligent Model Routing
Dynamically route each request to the optimal model across providers using policies, constraints, and real-time signals—no client rewrites or vendor-specific logic needed.
One endpoint, any model -
Cost-Aware Orchestration
Control spend with price-based routing, per-project limits, and smart downgrades—keeping quality high while preventing surprise bills in production workloads.
Optimize quality per dollar -
Resilient Fallback Flows
Define graceful failover chains across models and providers so timeouts, rate limits, or outages degrade smoothly instead of breaking user experiences.
Never ship single points of failure -
End-to-End Observability
Trace every request across providers with unified logs, metrics, and latency breakdowns to debug issues fast and tune prompts and routing policies confidently.
See every token, everywhere -
Task-Level Abstractions
Describe tasks like chat, embeddings, tools, or reranking once and let LLM.API translate them into each provider’s API, schema, and capabilities.
Standard tasks, many backends -
High-Throughput Batch APIs
Ship large workloads as batches with concurrency control, retries, and partial-failure handling built in—cutting overhead and maximizing throughput across providers.
Batch at scale, safely
When to Use — When NOT to Use
Use it if...
- You need a general-purpose model from Perceptron for prototyping typical AI features.
- You need basic question-answering or summarization without demanding complex multi-step reasoning.
- Your use case involves moderate-length chat interactions with straightforward instructions and responses.
- You need an additional non-OpenAI model to diversify provider or vendor dependencies.
- Your use case involves experimentation or benchmarking across multiple mid-range foundation models.
- You need a Perceptron-native model to integrate with existing Perceptron tooling or dashboards.
Avoid if...
- You need state-of-the-art reasoning, planning, or tool use comparable to leading flagship models.
- Your workload requires very long context windows handling large codebases or multi-document reasoning.
- You need specialized capabilities like high-fidelity image generation or advanced multimodal understanding.
- Your workload requires strict, well-documented compliance certifications or audited industry-specific guarantees.
- You need a highly mature ecosystem with extensive third-party integrations, plugins, and community tools.
- Your workload requires detailed, battle-tested performance benchmarks across many public evaluation suites.
