Best LLM APIs in 2026
Top general-purpose AI models available via API today.
How we picked these
- We exclude finetunes and derivative variants — only canonical models from each vendor.
- We require text-in / text-out modalities and a published per-token price.
- Models are ranked by how widely they are offered (provider count) — popularity is a proxy for production maturity.

Recommended stack by tier
Same shortlist sliced four ways — pick the tier that matches your budget and constraints.
Budget
OpenAI$0.030 in / $0.170 out · 128K ctx
Lowest total per-1M-token cost in this list ($0.20).
Lowest-cost option that still meets the use case. Pick this when you have high volume or strict unit-economics.
Balanced
Moonshot AI$0.950 in / $4.00 out · 262K ctx
Median price ($4.95) — typically the safest default.
Good-enough quality at a mid-tier price. The default choice for most production apps.
Premium
OpenAI$5.00 in / $30.00 out · 1.05M ctx
Highest-priced pick in the list ($35.00) — usually the flagship.
Highest-capability model in this list. Pick when accuracy or reasoning matters more than cost.
Open-weight
DeepSeek$0.140 in / $0.280 out · 1M ctx
Open weights and the cheapest in that subset ($0.42).
Open weights — self-host on your own GPUs, fine-tune on private data, run offline. Pricing here reflects the cheapest API host.
Frequently asked questions
Which AI model is the best for general-purpose API use in 2026?
Right now we put GLM-5.2 from Z.AI / Zhipu at the top, primarily because it is offered on the most providers and consistently exposes a clean text-in / text-out API at predictable pricing. Rankings are recomputed from live model metadata — see "How we picked these" above for the exact rule.
What is the cheapest option in this list?
gpt-oss-120b (OpenAI) is the lowest-priced pick at $0.030 per 1M input tokens and $0.170 per 1M output tokens. Costs from other entries scale up from there.
How are these rankings generated?
Each pick comes from a programmatic rule defined in our use-case-rules config: a hard filter (e.g. tool calling required, context ≥ 100K) plus a numeric score combining capability, context window and price. We never hand-curate the order, but we do hand-curate the rule. Underlying model metadata is refreshed daily from a normalised canonical catalogue.
How often is this page updated?
The underlying model data is refreshed once per day, and the static page is rebuilt when the data changes. The 'Last updated' date below shows the most recent rebuild.
Are 'Unknown' priced models excluded?
Yes. We only rank models with a published per-million-token price. 'Unknown' here means the provider does not publish a public rate card — it is not the same as 'free', so showing them at $0 would mislead.
