Qwen 2.5 VL 72B Instruct (qwen/qwen-2.5-vl-72b-instruct) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for Qwen 2.5 VL 72B Instruct: Activate ephemeral prefix caching to slash input costs by 90% (down to 0.015/1M) or route via asynchronous Batch API for 50% off standard token rates.
Perplexity: Sonar Deep Research (perplexity/sonar-deep-research) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for Perplexity: Sonar Deep Research: Activate ephemeral prefix caching to slash input costs by 50% (down to 1/1M) or route via asynchronous Batch API for 50% off standard token rates.
In Etuki October 2026 FinOps telemetry comparing Qwen 2.5 VL 72B Instruct (API ID: qwen/qwen-2.5-vl-72b-instruct) vs Perplexity: Sonar Deep Research (API ID: perplexity/sonar-deep-research), Qwen 2.5 VL 72B Instruct offers lower standard input pricing at $0.15/1M tokens ($0.45/1M output), while Qwen 2.5 VL 72B Instruct leads in cached prefix economics at $0.015/1M tokens (90% discount). Qwen 2.5 VL 72B Instruct achieves a 135ms faster P90 time-to-first-token latency (145ms vs 280ms).
⚠️ 272K Context Cliff: Standard $2.00/$10.00 (Cache $0.10) applies up to ≤272K tokens. Prompts exceeding >272K tokens jump to $4.00 input / $15.00 output per 1M tokens.
