KALINGA - Experiment No. 02 (GGUF)

One language. Done properly. Measured honestly.

Kalinga-02 is a continued-pretrained sarvamai/sarvam-1 (2.5B) with a custom Odia-optimized tokenizer, trained on ~1.13B tokens of Odia. This repo hosts community-friendly GGUF quants.

File Quant Size
kalinga-02-Q4_K_M.gguf recommended daily use ~1.5 GB
kalinga-02-Q5_K_M.gguf higher fidelity ~1.7 GB
kalinga-02-Q8_0.gguf near-lossless ~2.7 GB

Converted with llama.cpp convert_hf_to_gguf.py (f16) + llama-quantize.

Run it

ollama create kalinga-02 -f Modelfile   # Modelfile: FROM ./kalinga-02-Q4_K_M.gguf
ollama run kalinga-02
llama-cli -m kalinga-02-Q4_K_M.gguf -p "ଓଡ଼ିଆରେ ଗୋଟିଏ ବାକ୍ୟ ଲେଖ" -n 128

The receipts

Same harness, both models, no cherry-picking.

Held-out perplexity, 2,000 docs, bits-per-char (tokenizer-fair):

Task sarvam-1 (base) kalinga-02
overall 1.96 2.91
qa 1.45 2.64
generation 2.48 2.62
translation 1.07 3.70

Multiple-choice accuracy, 64,031 rows, logprob-scored (no generation):

Model Accuracy
sarvam-1 (base) 40.82%
kalinga-02 38.55%

What the numbers say: this training recipe degrades the base on fluency and task accuracy, and English ability collapses. This quant release exists so the community can reproduce, probe, and build on a documented result - the next experiment starts from evidence.

License / lineage

Base: sarvamai/sarvam-1 (non-commercial terms flow downstream). This is an experiment, tagged accordingly - use with eyes open.
