Model reference · open weights
gigaam-ctc is an open-weight audio or speech model from waveletdeboshir. AxForge deploys and operates it for you on dedicated EU-owned hardware — with the licence handled where one is required.
Available as managed deployment — configured and operated for you on dedicated EU hardware, quoted per deployment.

About
This is an unofficial Transformers wrapper for the original GigaAM-v2-CTC model released by SberDevices.
This is GigaAM-v2-CTC with transformers library interface.
File gigaam_transformers.py contains model, feature extractor and tokenizer classes with usual transformers methods. Model can be initialized with transformers auto classes (see an example below).
my lib versions:
torch 2.7.1torchaudio 2.7.1transformers 4.49.0accelerate 1.5.2Usage is same as other transformers ASR models.
from transformers import AutoModel, AutoProcessor
import torch
import torchaudio
# load audio
wav, sr = torchaudio.load("audio.wav")
# resample if necessary
wav = torchaudio.functional.resample(wav, sr, 16000)
# load model and processor
processor = AutoProcessor.from_pretrained("waveletdeboshir/gigaam-ctc", trust_remote_code=True)
model = AutoModel.from_pretrained("waveletdeboshir/gigaam-ctc", trust_remote_code=True)
model.eval()
input_features = processor(wav[0], sampling_rate=16000, return_tensors="pt")
# predict
with torch.no_grad():
logits = model(**input_features).logits
# greedy decoding
greedy_ids = logits.argmax(dim=-1)
# decode token ids to text
transcription = processor.batch_decode(greedy_ids)[0]

How it works
Using it via the API
Once AxForge deploys gigaam-ctc for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (gigaam-ctc below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \ -H "Authorization: Bearer $AXFORGE_API_KEY" \ -F model="gigaam-ctc" -F file=@audio.mp3
