Cheapest for this job

“Tier” is our rough capability judgment (1 = light, 4 = frontier), not a benchmark. Picks are the cheapest models at or above the tier.

Simple Q&A / chat

Needs tier ≥1; example 10M in / 2M out per month
  1. GPT-OSS 20B (Groq) — $1.35/mo
  2. GPT-6 Luna — $2.00/mo
  3. Qwen3.8 Flash (Together) — $2.44/mo

Caveat: Small models are fine for FAQs and short answers but hallucinate more on niche facts.

Coding

Needs tier ≥2; example 20M in / 5M out per month
  1. GLM-5.3 Flash (Together) — $5.50/mo
  2. GPT-OSS 120B (Groq) — $6.00/mo
  3. DeepSeek V4.1 Flash — $12.00/mo

Caveat: Coding quality varies a lot by language and repo size; run your own tests before switching.

Long documents

Needs tier ≥2; example 100M in / 2M out per month
  1. DeepSeek V4.1 Flash — $32.40/mo
  2. Mistral Large 4 — $72.18/mo
  3. Grok 4.3 — $130.00/mo

Caveat: Only models with a published context ≥500K are considered; several providers bill more above 200K–272K prompt tokens.

Hard reasoning

Needs tier ≥3; example 10M in / 10M out per month
  1. Mistral Large 4 — $27.70/mo
  2. DeepSeek V4 Pro — $52.80/mo
  3. Grok 4.7 — $80.00/mo

Caveat: Reasoning models spend extra 'thinking' tokens billed as output, so real cost can be several times this estimate.

FAQ

How do AI model API prices work?
Providers bill separately for input tokens (your prompt) and output tokens (the model reply), usually in US dollars per 1 million tokens. TokenTally shows the standard pay-as-you-go list rate: no batch discount, no cached input, short-context prompts.
How often does TokenTally update prices?
We re-check official provider pricing pages and rebuild the table regularly. This snapshot was last verified on 2026-10-14. Every change is recorded on the price-change log and in the RSS feed at /changes.xml.
Which AI model API is cheapest right now?
Among the 25 models we track, the lowest input list price is $0.075/1M for GPT-OSS 20B (Groq) from Groq. For a workload match, use the Cheapest for this job pages or the savings calculator — the cheapest overall model is not always the best fit.
Where do the prices come from?
Every row links to the provider's official pricing page (the src URL in /prices.json). We mark a row verified only after reading that page. Always check the official pricing page before you buy.
Can AI agents download the price table?
Yes. Prefer /prices.json or /prices.csv over scraping HTML, and start with /llms.txt for an agent-oriented map of the site. Prices may be wrong or out of date — check the provider src URL before relying on them.
