AVELIN Model Families

AVELIN is an AI Laboratory that builds and trains Cross-Model MoE — a proprietary Mixture-of-Experts meta-model architecture with difficulty-based cascading. We fuse open-weight models into 9 specialist families across 3 categories, producing trained intelligence that exceeds any single model:

CategoryFamiliesCost Advantage
Intelligencefast, pro, ultraup to 85% cheaper than frontier alternatives
Codingcoding-fast, coding-pro, coding-ultraup to 86% cheaper than frontier alternatives
Agenticagentic-fast, agentic-pro, agentic-ultraup to 87% cheaper than frontier alternatives

Cross-Model MoE is not routing or pass-through — it is a trained meta-model, not a router. A prompt-vector classifier (trained on 1 year of production data, 90% accuracy) classifies each request and applies difficulty-based cascading and cost-aware routing across specialist layers. Routers pick one model via if/else rules. We cascade across trained experts and synthesize. The platform is continuously self-improving: new models are evaluated and integrated within 48 hours of release.

Our models are available via enterprise licensing (sovereign deployment on your GPUs — request a POC) or cloud API (usage-based, $0.285–$12.50 per 1M tokens).

Renamed models: avelin-coding, avelin-coding-plus, avelin-coding-architect, avelin-agentic, and avelin-agentic-high are legacy names for avelin-coding-fast, avelin-coding-pro, avelin-coding-ultra, avelin-agentic-pro, and avelin-agentic-ultra. The old names keep working as server-side aliases. See the Model Catalog.


Intelligence Family

Frontier reasoning and multimodal intelligence — up to 85% cheaper than frontier alternatives.

The Intelligence family is built for analysis, strategy, knowledge work, research synthesis, and customer-facing assistants where answer quality, reasoning depth, and multimodal understanding come first. Through Cross-Model MoE, these models deliver frontier-tier intelligence under a single API with difficulty-based cascading for resilience and SLA-grade uptime.

avelin-proHigh-efficiency reasoning256K tokens65K$1.40 / $4.40
avelin-fastLow-latency, high-throughput256K tokens65K$0.30 / $1.20

Why 256K context matters: Process entire codebases, lengthy documents, or extended conversations in a single request. No chunking, no context loss, no compromises.

Key Capabilities

  • Deep multi-step reasoning for complex problem solving
  • Multimodal understanding (text, images, charts, documents)
  • Vision support on all three tiers for image analysis and document understanding
  • System messages for custom behavior and context
  • Function calling for structured outputs and tool integration
  • Streaming for real-time applications

When to use the Intelligence family

  • Strategic planning and executive decision support
  • Complex document analysis and synthesis
  • Customer-facing assistants requiring high quality
  • Research and knowledge work
  • Multimodal tasks involving images, charts, or documents
  • Tasks where accuracy and reasoning depth are critical

Coding Family

Enterprise coding agents — up to 86% cheaper than frontier alternatives.

The Coding family is purpose-built for software development workflows — from live debugging and root-cause analysis to multi-file refactors and whole-system design. These models are optimized specifically for software engineering, with tool use throughout; thinking is on by default on the pro and ultra tiers and off by default on the fast tier for latency. They're built for IDE plugins, autonomous coding agents, code-review pipelines, and engineering productivity platforms.

Models in this family

ModelPositioningContext WindowMax OutputThroughputInput/Output $/M

avelin-coding-ultraDeep architecture1M tokens65K~50 tps$2.50 / $12.50

Why 1M context is a game-changer: Load entire repositories into context. Understand cross-file dependencies, trace execution paths across modules, and refactor with complete codebase awareness. This isn't just a large context window — it's whole-repository intelligence.

Key Capabilities

  • Whole-repository understanding with 1M-token context windows
  • Multi-file refactoring with cross-cutting impact analysis
  • Live debugging and root-cause analysis
  • Code generation across multiple languages and frameworks
  • Test generation and code review
  • Security analysis and vulnerability detection
  • Architecture design and system planning
  • Tool use for IDE integration and automation

When to use the Coding family

  • Software development and engineering tasks
  • Code generation, refactoring, and optimization
  • Bug fixing and debugging
  • Code review and security analysis
  • System architecture and design decisions
  • IDE plugin development
  • Autonomous coding agents
  • CI/CD pipeline integration

Agentic Family

Purpose-built for autonomous agents — up to 87% cheaper than frontier alternatives.

The Agentic family is optimized for cost-effective agent workflows that fire thousands of model calls per workflow. Through Cross-Model MoE, these models maintain frontier reasoning quality while keeping per-step economics low, making them ideal for agent teams, research pipelines, RAG systems, and orchestration layers. They support on-prem deployment for data sovereignty and air-gapped environments.

Models in this family

avelin-agentic-fastCost-optimized256K tokens65K$0.285 / $1.14

The agentic advantage: Purpose-built for autonomous workflows that think, plan, and execute across hundreds of steps. With 256K context, your agents can maintain coherent state across complex, long-running tasks without losing track of goals or context.

Key Capabilities

  • Long-horizon planning across multiple steps and tools
  • Reliable tool calling with structured outputs
  • Parallel task orchestration for agent swarms
  • Configurable reasoning effort for cost optimization
  • On-prem deployment for regulated industries
  • High throughput for volume workloads

When to use the Agentic family

  • Autonomous and semi-autonomous agents
  • Multi-tool workflows requiring planning and execution
  • Research pipelines with iterative refinement
  • RAG systems with retrieval and synthesis
  • Orchestration layers managing multiple agents
  • High-volume classification and extraction
  • Regulated industries requiring data sovereignty
  • Cost-sensitive agent backends
