A meta-model analyzes incoming prompts and routes requests to the optimal model from a pool of dozens of language models, vision models, and multimodal models. The routing decision is made server-side based on prompt characteristics, task type, and model capability profiles, abstracting model selection from the user. This enables cost-optimization and quality-optimization without requiring explicit model selection in the API call.
Unique: Uses a meta-model to perform intelligent routing across dozens of heterogeneous models (text, vision, audio, video) in a single unified endpoint, rather than requiring developers to manually select models or maintain multiple API integrations. The routing is dynamic and server-side, enabling OpenRouter to rebalance the model pool without client-side changes.
vs alternatives: Unlike manually calling specific models via OpenRouter or competing APIs, Auto Router eliminates model selection friction and enables automatic cost-quality optimization across the entire model ecosystem without code changes.
The meta-model analyzes prompt content and structure to detect the primary task type (text generation, image generation, code generation, summarization, translation, image analysis, audio processing, etc.) and routes to a model optimized for that specific task. This involves parsing prompt semantics, detecting embedded images or media, and matching against a capability matrix of available models.
Unique: Performs semantic task detection on incoming prompts to classify intent (code vs. creative writing vs. image generation vs. analysis) and routes to specialized models rather than generic ones. This is distinct from simple load-balancing or round-robin routing — it matches task semantics to model capabilities.
vs alternatives: More intelligent than basic load-balancing and more flexible than fixed model selection, enabling a single endpoint to handle diverse tasks without explicit routing logic in application code.
The meta-model considers pricing tiers and model costs when routing, selecting the cheapest model capable of handling the task while maintaining quality thresholds. This enables automatic cost optimization without sacrificing output quality, by leveraging cheaper models for simpler tasks and premium models only when necessary.
Unique: Incorporates real-time pricing data and cost-per-token metrics into routing decisions, selecting models that minimize cost while meeting quality thresholds. This is a cost-aware variant of capability-based routing, distinct from quality-only or speed-only optimization strategies.
vs alternatives: Provides automatic cost optimization without requiring developers to manually compare model pricing or implement their own cost-aware routing logic, reducing operational overhead for cost-sensitive applications.
The meta-model prioritizes output quality and capability when routing, selecting the most capable model for a given task regardless of cost. This involves evaluating model performance benchmarks, capability matrices, and task-specific quality metrics to route to the best-performing model available.
Unique: Explicitly optimizes for output quality and model capability rather than cost or speed, routing to the highest-performing models available. This is the inverse of cost-optimization, prioritizing capability matrices and benchmark performance in routing decisions.
vs alternatives: Ensures access to the best available models without requiring developers to research and manually select premium models, providing automatic quality assurance through intelligent routing.
The meta-model routes requests to the fastest-responding models available, minimizing end-to-end latency by considering model inference speed, server response times, and network proximity. This enables low-latency applications without sacrificing too much quality, by selecting models that balance speed and capability.
Unique: Incorporates inference speed and response time metrics into routing decisions, selecting models that minimize end-to-end latency. This is distinct from cost or quality optimization, focusing on speed as the primary optimization criterion.
vs alternatives: Automatically routes to the fastest models without requiring developers to benchmark model latencies or implement custom speed-aware routing logic, enabling low-latency applications without manual optimization.
Auto Router provides a single, unified API endpoint that abstracts away the complexity of multiple underlying model providers (OpenAI, Anthropic, Mistral, Cohere, etc.). Developers call a single endpoint with a standard request format, and the meta-model handles provider-specific API translation, authentication, and response normalization internally.
Unique: Provides a single, standardized API endpoint that abstracts away provider-specific implementation details (authentication, request formats, response structures) for dozens of models across multiple providers. This enables true provider-agnostic application development without managing separate integrations.
vs alternatives: Eliminates the need to maintain separate integrations for OpenAI, Anthropic, Mistral, and other providers, reducing code complexity and enabling dynamic provider switching without application-level changes.
Auto Router provides metadata in API responses indicating which specific model was selected for each request, enabling developers to track model usage patterns, audit routing decisions, and understand which models are being used for which tasks. This transparency is critical for cost analysis, performance monitoring, and debugging routing behavior.
Unique: Exposes model selection decisions in API responses, enabling developers to see which model was routed to and build custom analytics on top. This transparency is essential for understanding routing behavior and optimizing application-level decisions.
vs alternatives: Provides visibility into routing decisions that competing services may hide, enabling developers to audit, analyze, and optimize their usage patterns without relying on opaque black-box routing.

Provides keypoint annotations for all people in images using a standardized 17-joint skeleton model (head, shoulders, elbows, wrists, hips, knees, ankles) with (x, y, visibility) tuples per joint. Visibility flag indicates whether keypoint is annotated (1), occluded (0), or outside image bounds (0). Keypoints are linked to parent person instances via instance ID, enabling pose estimation evaluation at both individual and crowd-level scales. Annotations follow COCO Keypoints task specification with consistent coordinate system across all 330K images.
Unique: Standardized 17-joint skeleton with explicit visibility flags enables robust evaluation of pose estimation under occlusion; linked to instance segmentation masks allows joint-level accuracy analysis within person bounding boxes
