cRia-LM-75M is an open-weight model for text generation from Shreyan Mohanty, released under Apache License 2.0. It has 76M parameters and a 4,096-token context. At 16-bit it needs about 0.2 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index. It draws 6.9k downloads a month.

cRia-LM-75M is a 75.7M-parameter base language model built as a Relaxed Recursive Transformer (RRT). It uses a shared 11-layer recurrent block evaluated twice, with pass-specific LoRA parameters on the second traversal.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Oct 13, 2026.

Model Card

By Shreyan Mohanty, published under apache-2.0, revision a424901d152c.

Cria (noun): a baby llama, alpaca, vicuña, or guanaco. Pronounced ˈkrē-ə.

~ Merriam-Webster

cRia-LM-75M is a 75.7M-parameter base language model built as a Relaxed Recursive Transformer (RRT). It uses a shared 11-layer recurrent block evaluated twice, with pass-specific LoRA parameters on the second traversal.

Training was carried out in three stages. Stage 1 established the 2K base model over 10B tokens. Stage 2 continued training with a 2B-token budget and a capability-focused data curriculum; the released Stage 2 checkpoint is step 10,000, corresponding to about 1.31B continuation tokens. Stage 3 extended the context window from 2,048 to 4,096 tokens with a 50M-token run on codelion/sutra-1B. The released checkpoint continues from that long-context stage with 35 learned residual-gain scalars and one epoch over the HellaSwag, ARC-Easy, ARC-Challenge, PIQA, SciQ and SWAG training splits.

Questions About cRia-LM-75M

How much GPU memory does cRia-LM-75M need?

About 0.2 GB at 16-bit and 0 GB at 4-bit: the weights (76M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run cRia-LM-75M on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use cRia-LM-75M commercially?

Yes. cRia-LM-75M is released under Apache License 2.0. The Apache License 2.0 is a permissive open-source license. It permits commercial use, modification and redistribution. It requires keeping the license and copyright notices and any NOTICE file, stating significant changes, and it includes an express patent grant from contributors.

What is cRia-LM-75M's context length?

4,096 tokens, from the maximum position embeddings in its published configuration.

Inferno-Exp-1.0

AlgoDriveAI

Inferno-Exp-1.0 is a 76.2M-parameter decoder-only base language model trained from scratch by AlgoDriveAI. It is a math-first model: its training data centers on arithmetic and math word problems, and it is geared toward the AxiomicLabs small-language-model benchmarks used in SLM challenges, ArithMark 3.0 and ArithMark 2.0 (results below). Future versions will build on this math foundation with improvements aimed at broader language understanding and logical reasoning. This is a base model (no instruction tuning). The model code ships in the repo, so load it with trustremotecode=True. All scores are zero-shot on the checkpoint in this repo. The ArithMark benchmarks were scored with…

Discovery

Convergent Intelligence

A 70M parameter causal language model built on the Mixture-of-Attentions (MoA) architecture — distance-based metric attention that respects the triangle inequality by construction, not approximation. Every attention head operates in a proper metric space. The geometry is enforced, not hoped for. Standard transformers compute attention as a dot product: Q·Kᵀ. This has no geometric meaning — it's a bilinear form, not a distance. Two tokens can be "close" by dot product while violating basic metric properties. MoA replaces this with negative squared distance under a learned diagonal Mahalanobis metric, then enforces the triangle inequality through a regularizer over random triples sampled…
