glm-5.1 API — compare providers
The same model (glm-5.1) is served by 15 providers; Baidu is the cheapest at $3.764/1M blended — the priciest (Venice) costs 70% more. On quality, glm-5.1 scores 1466 on the LMArena (Chatbot Arena) — so the cheapest endpoint is also the best value per dollar here.
Quality and intelligence scores are attached to the model itself — identical whichever provider serves it. Verified 2026-09-04.

Value = model Elo ÷ blended price per 1M tokens. Since the model's quality is identical across providers, the cheapest endpoint is also the best value per dollar.
Prices are per 1M tokens (USD). "Blended" = input + output, for coarse ranking. Same underlying model, 15 serving providers, 70% spread top to bottom. Context window: 204,800 tokens (131,072 max output) — see how it ranks in biggest context windows.

Cost per 1,000 requests by workload
What each provider actually bills for a representative job, not just the sticker price.

Self-host / quantized builds
Open weights under MIT — you can run glm-5.1 on your own hardware instead of paying per token. Quantized builds lower the memory footprint; whether it fits your GPU or Mac depends on the model's size. Formats: GGUF for llama.cpp / Ollama / LM Studio, AWQ and GPTQ for GPU serving, MLX for Apple silicon.
- GGUF builds llama.cpp · Ollama · LM Studio
- AWQ builds GPU serving (vLLM)
- GPTQ builds GPU serving
- MLX builds Apple silicon
- Ollama library one-command local run
Links search the live model hubs (Hugging Face, Ollama) so they track new builds as they appear — we don't host weights. Which formats exist depends on what the model owner and community have published.
