agentic.no Qwen2.5-3B Chat Completion

Choose this endpoint when you need a low-cost, fast OpenAI-compatible chat completion and are comfortable with a smaller 3B parameter quantized model (Qwen2.5-3B-Instruct-Q4). It is ideal for high-volume or cost-sensitive pipelines where GPT-4-class quality is not required, and when you want to pay per call via x402 micropayments rather than a subscription. Prefer it over larger model endpoints when latency and cost are the primary constraints.

• Payment not received or x402 micropayment fails — returns 402 Payment Required
• Messages array is empty or missing — returns 400 Bad Request
• max_tokens set below 1 — returns 400 validation error
• Model overloaded or host unavailable — returns 503 Service Unavailable
• Request timeout for very large max_tokens values
• Streaming requested but client doesn't handle SSE — partial or broken response
