Model index · 15 models · October 2026
Every model in the index, by vendor.
Each entry lists the SayGM price, the OpenRouter price with its top-up fee, and the workload the model suits. Open a model for its full spec sheet.

§ 01
How the prices spread
The same models on one chart. The gap is widest on Gemini and narrowest on Claude, and it reverses on input for two open-weight models.

§ 02
Confidential open-weight models
Two models in the index also come as a sealed -tee variant that runs inside an Intel TDX enclave, so prompts are decrypted only there.
- Kimi K3
The largest discount in the SayGM catalogue: 67.5 percent below Moonshot's list price on the open tier. A sealed -tee variant runs inside a TEE for prompts that must stay confidential.
- DeepSeek V4.1 Flash
40 percent below DeepSeek's list price on SayGM's open tier. OpenRouter's cheapest provider is cheaper still, but not confidential. The sealed -tee variant runs inside an Intel TDX enclave.
§ 03
Beyond this index
The index tracks ten widely used models. SayGM lists about 65, including the full Claude, GPT and Gemini lines and more open-weight options. OpenRouter lists several hundred, so check both catalogues if a niche or legacy model matters.
