Available models

alcf-proxy forwards to whatever models ALCF serves. This page mirrors ALCF's official catalog; run alcf-proxy models for the live, authoritative list (ids differ per cluster).

Recommended: ⭐ openai/gpt-oss-120b

openai/gpt-oss-120b is the recommended default for coding CLIs — it's a large reasoning model, always hot (low latency), supports tool calling, reasoning, and batch, and is available on both Sophia (openai/gpt-oss-120b) and Metis (gpt-oss-120b). It is alcf-proxy's built-in default and failover chain.

Flag Meaning
B Batch processing enabled
T Tool calling enabled
R Reasoning enabled
H Always hot (kept loaded → low latency)

Embedding models

mistralai/Mistral-7B-Instruct-v0.3-embed, Salesforce/SFR-Embedding-Mistral, and the genslm-test/genslm-esmc-* family (300M/600M, aminoacid/codon variants). Use the /v1/embeddings endpoint directly against ALCF for these.

Image segmentation

facebook/sam3 (promptable segmentation) — see ALCF's alcf-ai toolkit; not exposed through alcf-proxy's chat/responses/messages routes.

Metis cluster (metis/api, SambaNova)

Metis limitations

Batch processing and tool calling are not supported on Metis. Model ids on Metis have no openai/ prefix (e.g. gpt-oss-120b, not openai/gpt-oss-120b).

Notes

  • Coming soon (per ALCF): Cerebras CS-3 and GH200 Nvidia clusters.
  • The catalog changes over time — alcf-proxy models and ALCF's official docs are the source of truth.
  • Feature flags (B/T/R/H) are ALCF's; alcf-proxy passes tool-calling and reasoning through, so a model marked T/R works for agentic coding CLIs.
