**Axion1.5-0.3B-Base**
|
| 9 |
+
|
| 10 |
+
🧠 Axion1.5-0.3B-Base is a base language model with approximately 300 million parameters, trained purely for next-token prediction.
|
| 11 |
+
|
| 12 |
+
No instruction tuning.
|
| 13 |
+
No reinforcement learning.
|
| 14 |
+
No forced reasoning chains.
|
| 15 |
+
|
| 16 |
+
Just raw language modeling.
|
| 17 |
+
|
| 18 |
+
This model exists with a clear goal: to act as a clean, transparent baseline for future experiments focused on explicit reasoning and structured thinking.
|
| 19 |
+
|
| 20 |
+
What this model is
|
| 21 |
+
|
| 22 |
+
A foundation / base model
|
| 23 |
+
|
| 24 |
+
Trained only with next-token prediction
|
| 25 |
+
|
| 26 |
+
Not optimized for chat or instruction-following
|
| 27 |
+
|
| 28 |
+
Designed as a reference point for research and comparison
|
| 29 |
+
|
| 30 |
+
A functional “blank mind” before reasoning specialization
|
| 31 |
+
|
| 32 |
+
What this model is not
|
| 33 |
+
|
| 34 |
+
❌ Not a chatbot
|
| 35 |
+
|
| 36 |
+
❌ Not instruction-tuned
|
| 37 |
+
|
| 38 |
+
❌ Not aligned for safety or helpfulness
|
| 39 |
+
|
| 40 |
+
❌ Not optimized for long conversations
|
| 41 |
+
|
| 42 |
+
❌ Not a reasoning model (yet)
|
| 43 |
+
|
| 44 |
+
If you are looking for a model that follows instructions or explains its thoughts, this is not it.
|
| 45 |
+
|
| 46 |
+
Why release a base model?
|
| 47 |
+
|
| 48 |
+
Releasing the base model publicly allows:
|
| 49 |
+
|
| 50 |
+
Transparent evaluation of raw language modeling quality
|
| 51 |
+
|
| 52 |
+
Fair comparison with future Axion reasoning variants
|
| 53 |
+
|
| 54 |
+
Reproducibility and honest benchmarking
|
| 55 |
+
|
| 56 |
+
A clear separation between language competence and reasoning behavior
|
| 57 |
+
|
| 58 |
+
Many projects hide their base models.
|
| 59 |
+
Axion does the opposite.
|
| 60 |
+
|
| 61 |
+
Intended use
|
| 62 |
+
|
| 63 |
+
Research and experimentation
|
| 64 |
+
|
| 65 |
+
Fine-tuning for instruction-following or reasoning tasks
|
| 66 |
+
|
| 67 |
+
Studying the effects of reasoning-oriented datasets
|
| 68 |
+
|
| 69 |
+
Serving as a backbone for Axion1.5-Reasoning variants
|
| 70 |
+
|
| 71 |
+
Limitations
|
| 72 |
+
|
| 73 |
+
Because this model is trained only for next-token prediction:
|
| 74 |
+
|
| 75 |
+
It may produce incoherent or incomplete responses
|
| 76 |
+
|
| 77 |
+
It does not reliably follow instructions
|
| 78 |
+
|
| 79 |
+
It does not reason step-by-step
|
| 80 |
+
|
| 81 |
+
It may hallucinate or contradict itself
|
| 82 |
+
|
| 83 |
+
These limitations are expected and acknowledged.
|
| 84 |
+
|
| 85 |
+
Future work
|
| 86 |
+
|
| 87 |
+
This release is part of a broader project:
|
| 88 |
+
|
| 89 |
+
Axion1.5-Reasoning – fine-tuned for structured reasoning
|
| 90 |
+
|
| 91 |
+
Axion-Critic – models focused on evaluation and self-critique
|
| 92 |
+
|
| 93 |
+
Experiments with short, verifiable reasoning traces
|
| 94 |
+
|
| 95 |
+
The base model will remain unchanged to preserve its value as a reference.
|
| 96 |
+
|
| 97 |
+
Philosophy
|
| 98 |
+
|
| 99 |
+
Scale is not intelligence.
|
| 100 |
+
Structure matters.
|
| 101 |
+
|
| 102 |
+
Axion explores whether smaller models, trained with the right constraints, can develop more meaningful reasoning behaviors.
|
| 103 |
+
|
| 104 |
+
This is an experiment.
|
| 105 |
+
And experiments are allowed to fail.
|
| 106 |
+
|
| 107 |
+
Acknowledgements
|
| 108 |
+
|
| 109 |
+
Created as an independent research project focused on understanding how reasoning emerges in language models.
