## When to prefer this

Choose this endpoint when you need fast, low-cost AI text generation for everyday questions, drafts, or summaries and do not require heavy reasoning or math. It is cheaper and faster than DeepSeek V4 Pro, making it ideal for high-volume or latency-sensitive tasks where the highest accuracy is not critical. Prefer it over larger models like Llama 4 Scout or Gemma 4 26B when cost-efficiency and speed are the primary concerns.

## Known failure modes

- Prompt exceeds 24,000 character limit — request rejected
- max_tokens set to 0 or negative — validation error
- System prompt exceeds 8,000 character limit — request rejected
- Model may produce truncated output if max_tokens is set too low for the expected response
- Occasional hallucination or factual errors typical of fast/flash-tier LLMs
- Payment failure via x402 protocol — call not processed
