As OLMO-2 is Totally Open Mannequin, Let’s see what’s the distinction between Open Weight Fashions, Partially Open Fashions and Totally Open Fashions:
Open Weight Fashions
Llama-2-13B, Mistral-7B-v0.3, Llama-3.1-8B, Mistral-Nemo-12B, Qwen-2.5-7B, Gemma-2-9B, Qwen-2.5-14B: These fashions share a key trait: their weights are publicly out there. This enables builders to make use of them for varied NLP duties. Nevertheless, important particulars about their coaching course of, reminiscent of the precise dataset composition, coaching code, and hyperparameters, are usually not absolutely disclosed. This makes them “open weight,” however not absolutely clear.
Partially Open Fashions
StableLM-2-128, Zamba-2-7B: These fashions fall right into a grey space. They provide some further data past simply the weights, however not the complete image. StableLM-2-128, for instance, lists coaching FLOPS, suggesting extra transparency than purely open-weight fashions. Nevertheless, the absence of full coaching knowledge and code locations it within the “partially open” class.
Totally Open Fashions
Amber-7B, OLMo-7B, MAP-Neo-7B, OLMo-0424-7B, DCLM-7B, OLMo-2-1124-7B, OLMo-2-1124-13B: These fashions stand out resulting from their complete openness. AI2 (Allen Institute for AI), the group behind the OLMo collection, has launched all the things crucial for full transparency and reproducibility: weights, coaching knowledge (or detailed descriptions of it), coaching code, the complete coaching “recipe” (together with hyperparameters), intermediate checkpoints, and instruction-tuned variations. This enables researchers to deeply analyze these fashions, perceive their strengths and weaknesses, and construct upon them.
Key Variations
Characteristic | Open Weight Fashions | Partially Open Fashions | Totally Open Fashions |
Weights | Launched | Launched | Launched |
Coaching Knowledge | Sometimes Not | Partially Obtainable | Totally Obtainable |
Coaching Code | Sometimes Not | Partially Obtainable | Totally Obtainable |
Coaching Recipe | Sometimes Not | Partially Obtainable | Totally Obtainable |
Reproducibility | Restricted | Greater than Open Weight, Lower than Totally Open | Full |
Transparency | Low | Medium | Excessive |
