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
- Qwen3.8 Flash (Together) — $2.44/mo
Caveat: Small models are fine for FAQs and short answers but hallucinate more on niche facts.

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
