Spark 5M model closes 350M gap

Spark v4 is a 4.98M-parameter Llama model trained with HF Transformers that the author says comes surprisingly close to the older Apex 350M baseline on a small benchmark set. The research page shows steady gains from earlier Spark versions, but the smaller model still trails the larger one on the listed evals.

// ANALYSIS

This is a real efficiency result, not a magic-size victory. The data suggests Spark is getting much more out of training quality and scale discipline, but it still does not overturn the basic advantage of a 350M model.

  • Spark v4 reaches 4.98M parameters and ~50 MB FP16 inference RAM, so the deployment story is genuinely attractive
  • The benchmark table still favors Apex 350M on PIQA, HellaSwag, final loss, and overall output quality
  • Training on 500k docs and 0.7B tokens shows how much data matters when a model is this small
  • The biggest takeaway is compression discipline: a tiny Llama can become unexpectedly capable, but it remains a specialized research demo rather than a broad replacement
  • The "Spark v5 coming soon" note suggests this is still an active iteration cycle, not a finished product
