GPT-5.1 and Nous Hermes Are Now Available in Puter.js
We're excited to announce that Puter.js now supports GPT-5.1 and Nous Research's Hermes, giving developers free, unlimited access to OpenAI's latest iterative update and Nous Research's powerful instruction-following models.
GPT-5.1
GPT-5.1 brings meaningful improvements to the GPT-5 family with new chat, codex and mini models.
// Deep reasoning for complex problems
puter.ai.chat("Write a Python function to sort a list", {
model: 'gpt-5.1'
});
// Fast, conversational responses with adaptive reasoning
puter.ai.chat("Explain quantum computing in simple terms", {
model: 'gpt-5.1-chat-latest'
});
Hermes
Nous Research's Hermes models are renowned for their ability to follow instructions precisely. The latest Hermes 4 family includes models ranging from 70B to 405B parameters, all trained on high-quality datasets for superior performance on reasoning, coding, and general conversation tasks.
What makes Hermes special is its focus on alignment and instruction adherence—the models excel at understanding exactly what you want and delivering it without unnecessary verbosity or deviation.
// Complex reasoning with Hermes 4 70B
puter.ai.chat("Analyze the ethical implications of artificial general intelligence from multiple philosophical perspectives", {
model: 'nousresearch/hermes-4-70b'
});
// Maximum capability with Hermes 4 405B
puter.ai.chat("Create a detailed technical specification for a distributed database system", {
model: 'nousresearch/hermes-4-405b'
});
