Model overview

openchat_3.5 is published by openchat as a text-generation fine-tune. Captured configuration identifies MistralForCausalLM with a mistral model type under Apache-2.0. According to the model card, it is a 7B conversational model trained with C-RLFT on mixed-quality instruction data.

Recorded capabilities

C-RLFT mixed-quality tuning

According to the model card, the model is fine-tuned with C-RLFT on mixed-quality instruction data without preference labels.

Documented vLLM serving path

The model card documents an OpenAI-compatible API server using vLLM, listening on localhost:18888, with a 24GB consumer-GPU note and tensor-parallel option.

Chat and coding request modes

The model card provides separate chat and coding request examples, including a Code condition for code-oriented prompts and a conversation template.

Apache-2.0 distribution

Captured metadata and the model card both record Apache-2.0 licensing for the model and code.

Use cases in the source record

  • Conversational text-generation work through the publisher-documented OpenAI-compatible API server and Web UI.
  • Code-oriented prompts using the card's documented Code condition and chat-completion request format.

Limitations and unknowns

  • No parameter count was extracted from structured metadata.
  • Provider state is historical snapshot data and should be refreshed before being presented as current availability.
  • MT-bench and ChatGPT-comparison statements come from the publisher model card and have not been independently verified by Ethen.
  • No pricing, VRAM beyond the publisher's 24GB serving note, latency, or knowledge-cutoff values were extracted.
