- Use provider model ID "accounts/fireworks/models/openchat-3p5-0106-7b", not the LLMReference slug "openchat-3.5-0106".
- Fireworks model IDs use "accounts/fireworks/models/{model-name}" format, e.g. "accounts/fireworks/models/llama4-scout-instruct-basic" or "accounts/fireworks/models/deepseek-r1".
- The examples expect FIREWORKS_API_KEY; rename it only if your application config maps the new variable.

About OpenChat 3.5 (0106)
OpenChat 3.5 is an open-source large language model renowned for delivering performance on par with ChatGPT despite having just 7 billion parameters compared to ChatGPT's 70 billion. Built on a transformer architecture, this model uses C-RLFT (Constrained Reinforcement Learning from Trajectories) to learn from mixed-quality data without requiring explicit preference labels. It adeptly handles tasks such as text and code generation, including languages like HTML5 and JavaScript, and excels in multi-turn conversations. OpenChat 3.5 is open-source, making it an appealing choice for developers and researchers, and it is optimized to run efficiently on consumer-grade GPUs with 24GB of RAM.
