Some are not strong enough for production, but they are great for testing your setup. A few free ones are actually pretty capable, like Nvidia Nemotron and Google Gemma.\n\nYou can also pick paid models directly from providers or through OpenRouter.\n\nRight now, there are no free image/video generation models on OpenRouter. Hopefully that changes later.\n\nLimitation: free models may hit rate limits and get lower priority during busy times.\n\nA quick comparison chart is attached to show differences between Nvidia Nemotron, Google Gemma, and Claude’s current flagship model, Opus 4.7.\n\nThere is also a short explanation of reasoning vs completion at the end of this article.\n\nIn Hermes\n\nBackup your current config.yaml\n\n```\ncp ~/.hermes/config.yaml ~/.hermes/config.yaml.backup\n```\n\nShow current model configuration\n\n```\nhermes config show\n```\n\nYou should see any other configured model similar to this You should see a configured model similar to this:\n\n```\n◆ Model  Model:        {'default': 'elephant-alpha', 'provider': 'openrouter', 'base_url': 'https://openrouter.ai/api/v1', 'api_mode': 'chat_completions'}  Max turns:    90\n```\n\nSet the primary model\n\n```\nhermes config set model \"nvidia/nemotron-3-super-120b-a12b:free\"\n✓ Set model = nvidia/nemotron-3-super-120b-a12b:free in /home/jeff/.hermes/config.yaml\n```\n\nConfigure fallback models\n\n```\nhermes config edit\n```\n\nThen edit it manually:\n\n```\nmodel:  default: nvidia/nemotron-3-super-120b-a12b:free  provider: openrouter  base_url: https://openrouter.ai/api/v1  api_mode: chat_completionsproviders: {}fallback_providers:- provider: openrouter  model: openrouter/free- provider: openrouter  model: openrouter/elephant-alpha\n```\n\nNote: openrouter/free provides best available free models from OpenRouter\n\nRestart gateway\n\n```\nhermes gateway restart\n```\n\nOther free available models\n\nYou can also browse free and paid models from OpenRouter and NousResearch here:\n\nWhen using free model via OpenRouter, you may receive a warning:\n\n```\nAPI call failed after 3 retries: HTTP 429: Rate limit exceeded: free-models-per-day.

A completion model predicts the most likely next word from learned patterns, while a reasoning model works through steps before giving the final response.\n\nCore Definitions\n\nCompletion (Pattern Matching): The model predicts the next most likely word (token) from patterns in training data. It usually responds in a single pass, so it is often faster and more fluent, but less deep.\n\nReasoning (Logical Deliberation): The model goes through an internal thinking phase, breaks a problem into steps, explores options, and checks itself before replying.", "url": "https://wpnews.pro/news/hermes-connects-nvidia-nemotron-model-via-openrouter-for-free", "canonical_source": "https://blog.devgenius.io/hermes-connects-nvidia-nemotron-model-via-openrouter-for-free-50d53ecf6443?source=rss----4e2c1156667e---4", "published_at": "2026-07-07 12:32:05+00:00", "updated_at": "2026-07-07 13:03:53.154055+00:00", "lang": "en", "topics": ["large-language-models", "ai-tools", "ai-infrastructure"], "entities": ["Nvidia", "OpenRouter", "Hermes", "Google", "Nemotron", "Gemma", "Claude"], "alternates": {"html": "https://wpnews.pro/news/hermes-connects-nvidia-nemotron-model-via-openrouter-for-free", "markdown": "https://wpnews.pro/news/hermes-connects-nvidia-nemotron-model-via-openrouter-for-free.md", "text": "https://wpnews.pro/news/hermes-connects-nvidia-nemotron-model-via-openrouter-for-free.txt", "jsonld": "https://wpnews.pro/news/hermes-connects-nvidia-nemotron-model-via-openrouter-for-free.jsonld"}}
