# Qwen3.6 27B pricing, and a costly pairing > Qwen3.6 27B pricing on Groq is $0.60 per million input and $3.00 output. A reasoning-tuned model on a 5x spread with no cached rate to fall back on. URL: https://getculpa.com/qwen-qwen3-6-27b-pricing Last reviewed: 2026-08-01 Rates effective: 2026-07-02 ## Answer Qwen3.6 27B pricing on Groq is $0.60 per million input tokens and $3.00 per million output tokens, a five-to-one spread, and the price book records no cached rate for it. A model tuned to reason out loud on a five-times output spread with no cache is the most expensive combination here. Culpa, a local-first LLM cost, margin, and forecast ledger, meters output tokens per feature so the reasoning is priced. ## Why this happens Two facts about this model compound rather than add. The output spread is five to one, which is frontier territory rather than open-weight territory, so anything that lengthens a response is expensive. And there's no cached rate to soften the input side, so a repeated system prompt pays in full on every call. A reasoning-tuned model naturally produces long outputs, which is the behaviour the price shape punishes hardest, and the usual escape route of caching the repeated block is closed. ## What this usually looks like - Output tokens per call here run well above your other open-weight models. - A repeated system prompt goes out on every call with no cached rate to reduce it. - Reasoning was enabled once for quality and its cost was never separated from the answer's. - This model's bill is dominated by output while its call count looks unremarkable. ## Common mistakes - Treating this like the other open-weight models on cost shape. Why it hurts: Its five-to-one spread is closer to a frontier model than to the flat ratios beside it. Do instead: Price it on the output side and set a max token limit that reflects what you render. - Leaving reasoning on for tasks that don't need it. Why it hurts: Reasoning tokens bill as output at five times input and most of them never reach a user. Do instead: Enable it per task rather than globally, and measure the quality difference on each. - Planning around a cached rate that isn't there. Why it hurts: A forecast assuming a cached discount reads low by whatever share of your input repeats. Do instead: Price the repeated prefix at full input rate, then decide whether to shorten it instead. ## Self-check - Compare output tokens per call here against your other models on similar work. - Separate reasoning output from delivered answer length. Only one of them reaches a user. - Price your repeated prefix at full input rate, since no cached rate applies. - Test the same task with reasoning off and score the difference honestly. - Check whether a flatter-ratio model on the same platform would do this work. ## What reasoning costs on a five-to-one spread (illustrative) 12 million input tokens a month, of which 9 million is a repeated prefix, and 4 million output, on Qwen3.6 27B at real Groq rates. Volumes are modelled. Base month: (12 x $0.60) + (4 x $3.00) = $7.20 + $12.00 = $19.20 Output is already 63% of the bill on a quarter of the tokens The 9M repeated prefix bills at full rate, 9 x $0.60 = $5.40, with no cached rate available Turn reasoning on and output doubles to 8M: $7.20 + $24.00 = $31.20 That's a 63% increase in total spend from the output side alone Output is already most of the bill before reasoning, and enabling it adds another 63%. With no cached rate to work on the input side, the only lever left is how much the model says. ## Cost figures Every figure carries its confidence and its source.

A range because the token volumes are modelled. ## FAQ Q: How much does Qwen3.6 27B cost on Groq? A: $0.60 per million input tokens and $3.00 per million output, re-verified against Groq's pricing page on 2026-08-01. The price book records no cached rate for it and Groq's page lists none. Q: Why is this model's price shape awkward? A: Because a five-to-one output spread and no cached rate work against each other. Long responses are expensive and the usual fix of caching the repeated input isn't available, so both of the standard levers are weakened at once. Q: Do reasoning tokens count as output? A: On most providers, yes, and they bill at the output rate whether or not a user ever sees them. On a five-to-one spread that makes reasoning the single most expensive setting you can leave switched on by default. ## Sources - Groq pricing: https://groq.com/pricing Run the free Cost Leak Scan: https://app.getculpa.com/scan?source=pseo&slug=qwen-qwen3-6-27b-pricing&cluster=model_pricing Machine-readable index of every guide: https://getculpa.com/api/pages Human-readable index of every guide: https://getculpa.com/guides Site overview: https://app.getculpa.com/llms.txt Privacy: Culpa runs on your infrastructure.
