avelin-fast

Model Positioning

avelin-fast is AVELIN's low-latency, high-throughput tier — optimized for speed and cost efficiency in routine, high-volume work. Built with AVELIN's Cross-Model MoE technology in our AI Lab, it fuses multiple model architectures into a single trained system optimized for speed behind a single endpoint.

Context window: 256K tokens input, 65K tokens output

Pricing: $0.30 input / $1.20 output per 1M tokens (cache read $0.03, cache write $0.38) — see Pricing

Vision support: When your request contains images, avelin-fast automatically routes to a vision-capable model behind the scenes. You send to avelin-fast — we handle the rest. No special model selection needed.

Choose this tier when you need quick, dependable answers at scale.

Cross-Model MoE

Our Cross-Model MoE uses a prompt-vector classifier trained on 1 year of production data to predict the optimal specialist with 90% accuracy. It applies difficulty-based cascading (simple tasks → fast models, complex tasks → multi-expert fusion) and cost-aware routing (same quality, cheapest path). This is not a router — routers pick one model via if/else rules. We cascade across trained experts and synthesize output quality above any single expert. Built with AVELIN's Cross-Model MoE technology in our AI Lab. Cross-Model MoE is a trained meta-model — not a router — that fuses knowledge from multiple model architectures into a single unified model. You call avelin-fast and get fast output based on task type and latency requirements. For image requests, vision capabilities are engaged automatically. No model selection needed.

Self-improving platform: As new frontier models are released, AVELIN integrates them within 48 hours. Your avelin-fast endpoint gets faster and smarter over time — automatically, with zero code changes.

Enterprise licensing: AVELIN models are available for sovereign deployment on customer GPUs. Request a POC for enterprise licensing — run AVELIN on your own infrastructure with full data sovereignty.

Best-Fit Workloads

  • High-volume drafting and rewriting
  • Classification, extraction, and tagging
  • Chat and assistant interactions where latency matters
  • Batch processing of routine requests

When to Choose avelin-fast

  • The task is routine and well-defined
  • You are processing many requests and care about cost and speed
  • Deep multi-step reasoning is not required

For ambiguous or high-stakes work, escalate to avelin-pro or avelin-ultra.
