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- GPT-OSS 20B (Groq) — $1.35/mo
- GPT-6 Luna — $2.00/mo
- Claude Haiku 5.5 — $2.00/mo
Caveat: Small models are fine for FAQs and short answers but hallucinate more on niche facts.
Full ranking for simple q&a / chat →Coding
Needs tier ≥2; example 20M in / 5M out per month- GLM-5.3 Flash (Together) — $5.50/mo
- GPT-OSS 120B (Groq) — $6.00/mo
- DeepSeek V4.1 Flash — $12.00/mo
Caveat: Coding quality varies a lot by language and repo size; run your own tests before switching.
Full ranking for coding →Long documents
Needs tier ≥2; example 100M in / 2M out per month- DeepSeek V4.1 Flash — $32.40/mo
- Mistral Large 4 — $72.18/mo
- 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.

Needs tier ≥3; example 10M in / 10M out per month- Mistral Large 4 — $27.70/mo
- DeepSeek V4 Pro — $52.80/mo
- 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 2026-10-15. 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 30 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.
