Run or Rent

Is it cheaper to run the model, or rent the API?

For people who use Ollama, LM Studio or llama.cpp, and for small firms deciding whether to buy a GPU or keep paying the API. The sums are in pounds, and every number has a source or is labelled an estimate.

Model and card

No shop price on file for this card.

Ofgem price cap, average electricity unit rate for a Direct Debit customer in England, Scotland and Wales on a single-rate default tariff. No VAT on electricity in this period, per Ofgem. The daily standing charge is not included. Your region and payment method can differ. Ofgem, 1 October 2026 to 31 December 2026.

Speed and power

Filled when a sourced run exists. Otherwise type the speed you see in Ollama, LM Studio or llama.cpp.

Starts at the card's maximum rated power. Lower it if you measured the draw.

Not enough yet

The API comes to £0.53 a month for this job. There is no speed for running it locally, so the electricity and the break-even are left blank.

Memory. Google: Gemma 3 27B against Radeon RX 7900 XTX's 24 GB, estimated from the Hub's published weight size across the common quants: BF16 54.9 GB no · Q8_0 29.1 GB no · Q6_K 22.6 GB yes · Q5_K_M 19.5 GB yes · Q4_K_M 16.6 GB yes · IQ4_XS 14.6 GB yes · Q3_K_M 13.4 GB yes · Q2_K 10.3 GB yes. At Q6_K, about 22.6 GB, 1.4 GB of the card's 24 GB is left for the context cache. Rule of thumb, not a measured file size.

Needs a speed
  • API cost is input tokens and output tokens, priced per million, times jobs per month. No caching, batch discount, or free tier.
  • Pound figures use the stored exchange rate. They are not a quote from the company that trained the model.
  • No tokens-per-second figure, so the electricity line is blank. Type one in if you have measured it.
  • API price: £0.0596 in and £0.335 out per million tokens, from $0.0800 and $0.450 at 0.74501 dollars to the pound on 2026-11-10. OpenRouter feed 2026-11-11.
  • Radeon RX 7900 XTX: 24 GB GDDR6. Typical board power (desktop): 355 W. Specs read 2026-11-11.
  • No sourced speed for this pair, and none was typed in.
  • Upper estimate, based on the official typical board power (desktop) of 355 W.
