Long Context
Use this when
High-throughput applications where cost and speed matter more than frontier-level quality, such as chatbots, content classification, and text summarization.
Skip this if
You need deep reasoning, long document analysis, complex code generation, or outputs where quality directly impacts user trust.
Extremely low cost at $0.02/$0.05 per 1M tokens — among the cheapest viable instruct models available
Fast inference speed due to small parameter count, ideal for real-time applications
Open-weight model allows self-hosting and fine-tuning for custom use cases
Solid instruction-following and chat performance for a sub-10B model
Weaknesses
Limited 16K context window falls significantly behind competitors like Gemini 3.1 Pro (1M+) and Claude Sonnet 4.6 (200K)
Noticeably weaker on complex multi-step reasoning and nuanced writing compared to flagship models
Struggles with advanced coding tasks, especially those requiring deep logic or large codebases
