LLM API pricing comparison (GPT, Claude, Gemini, Grok)

Static snapshot (May 2026): one combined table (input + output $/1M) for GPT, Claude, Gemini, and Grok; sorted by input then output; legacy models; official links below.

Published: 2026-05-01

Below is a manual static snapshot as of May 2026. One combined table lists Input ($/1M) and Output ($/1M) side by side; rows sort by input high → low, then by output high → low when input ties. The GPT, Claude, Gemini, and Grok columns list models with that exact pair (Standard / Paid→Standard). Batch / Flex / Priority and cached-input discounts are omitted unless noted.

Notes

  • GPT (OpenAI API) — Platform pricing → Standard, Flagship models (GPT‑5.5 / 5.4 / mini / nano / pro, GPT‑5.2 / 5.1 / 5 / mini / nano / pro, GPT‑4.1 / mini / nano, GPT‑4o / mini, GPT‑4 legacy, o1 / o3 / o4-mini / mini). Snapshot also aligns with openai.com/api/pricing for current flagship SKUs.
  • Claude (Anthropic) — Model pricing: Opus / Sonnet / Haiku rows (Haiku 3.5 retired on first-party API except Bedrock/Vertex).
  • Gemini (Google) — Gemini API pricing Paid → Standard text columns where split; Pro models use ≤200k vs >200k prompt tiers. gemini-3.1-flash-tts-preview is priced mainly on audio output ($20/M on Standard)—not included in the combined table below.
  • Grok (xAI) — Pricing: Grok 4.x chat rows; older Grok 3-era SKUs are not on this summary table (see console / language-models API if needed).

List price: input + output ($ / 1M tokens)

Rows are sorted by input price high → low. For the same input price, output is sorted high → low next. Each vendor column lists models with that exact (input, output) pair (Standard / Paid→Standard as in the Notes).

Haiku 3.5 is retired on the first-party Claude API except Bedrock/Vertex. Gemini Pro / Flash long-context rows use ≤200k vs >200k prompt token cutoffs. OpenAI gpt-4o default list price differs from gpt-4o-2024-05-13. Re-check official pages before production budgets.
