Base And Instruction Tuned Model Variants

via “instruction-tuned variant for aligned task performance”

Meta's multimodal 11B model with text and vision.

Unique: Instruction-tuned variant available as separate model checkpoint, enabling users to choose between raw language modeling and task-optimized behavior. Approach avoids RLHF complexity while providing instruction-following improvements through supervised fine-tuning on curated datasets.

vs others: Instruction-tuned variant provides task alignment without RLHF complexity, while remaining smaller and faster than larger instruction-tuned models (70B+). Separate checkpoint allows users to experiment with both variants without retraining.

via “instruction-following and task-specific fine-tuning”

Compact 3B model balancing capability with edge deployment.

Unique: Instruction-tuned variant integrated with torchtune framework enabling parameter-efficient fine-tuning on consumer GPUs (16GB VRAM) without full model retraining — most 3B competitors either lack instruction-tuning or require expensive full fine-tuning pipelines

vs others: Smaller parameter count than Mistral 7B enables faster fine-tuning iterations and cheaper GPU requirements while maintaining instruction-following capability comparable to larger models

via “instruction-tuned multimodal generation with alignment”

Meta's largest open multimodal model at 90B parameters.

Unique: Provides both base and instruction-tuned variants, allowing users to choose between raw model capability and aligned behavior, with torchtune framework enabling custom fine-tuning on proprietary instruction datasets

vs others: Open-weight instruction-tuned variants enable custom alignment without relying on proprietary API providers, though fine-tuning infrastructure requirements are higher than using managed APIs

via “base and instruction-tuned model variants”

Mistral's 12B model with 128K context window.

Unique: Dual-variant release strategy provides both pre-trained base model for custom fine-tuning and instruction-tuned variant for immediate deployment, enabling flexibility for different use cases without requiring downstream alignment

vs others: More flexible than single-variant models like Llama 3, offering choice between base and instruction-tuned without forcing users to fine-tune or accept pre-aligned behavior

via “base model raw generation for fine-tuning and domain adaptation”

DeepSeek's 236B MoE model specialized for code.

Unique: Provides base model variants without instruction-tuning, enabling full fine-tuning flexibility while maintaining the sparse MoE architecture and 128K context, allowing organizations to create domain-specific variants

vs others: Offers open-source base models for fine-tuning unlike proprietary APIs (GPT-4, Claude), enabling full control over model adaptation and proprietary data handling

via “foundation model for downstream fine-tuning and specialized adaptation”

01.AI's bilingual 34B model with 200K context option.

Unique: Designed as a foundation model for downstream specialization, as evidenced by its role in creating Yi-1.5 and subsequent 01.AI models. Strong base performance (76.3% MMLU, competitive coding/math) provides a robust starting point for fine-tuning without requiring full pretraining.

vs others: Enables faster specialization than training from scratch while maintaining competitive base performance, reducing time-to-market for domain-specific models compared to full pretraining or using smaller foundation models.

via “instruction-tuned-variant-for-chat-and-tasks”

Mistral's mixture-of-experts model with 176B total parameters.

Unique: Instruction-tuned variant achieves 90.8% on GSM8K through explicit training on mathematical reasoning tasks, demonstrating that instruction-tuning improves task-specific performance. This variant is optimized for following user instructions vs the base model's general language modeling.

vs others: Better instruction-following than base model; comparable to GPT-3.5-turbo on chat tasks (specific benchmarks unknown); open-source licensing enables fine-tuning for custom instructions vs closed-source models.

via “no-built-in-safety-guardrails-base-model”

Mistral's mixture-of-experts model with efficient routing.

Unique: Base model has no built-in safety guardrails and will follow any instruction without refusal, prioritizing capability and flexibility over safety by default. Differs from Instruct variant which has learned safety behavior through DPO, and from commercial models with built-in content filtering.

vs others: Provides unconstrained base model for research and fine-tuning without safety-induced refusals, whereas commercial models (GPT-3.5, Claude) have built-in safety guardrails that may interfere with capability assessment or domain-specific applications.

via “model versioning and fine-tuning infrastructure”

Run ML models via API — thousands of models, pay-per-second, custom model deployment via Cog.

Unique: Replicate's fast-booting fine-tunes avoid idle billing by using a specialized deployment mode that only charges for active inference, reducing the cost of frequently-accessed custom models. This differs from standard private model deployments which bill for idle time.

vs others: Simpler than managing fine-tuning infrastructure on AWS SageMaker or Hugging Face, but less documented and with unclear feature parity across model types.

text-generation model by undefined. 1,93,69,646 downloads.

Unique: Qwen3-0.6B-Base provides a clean pre-trained foundation optimized for efficient fine-tuning through careful layer design and initialization. The model supports both LoRA (parameter-efficient) and full fine-tuning, with LoRA adapters as small as 10MB enabling rapid iteration and deployment of multiple specialized variants.

vs others: Smaller base model than Phi-3-mini-base (3.8B) enables faster fine-tuning and deployment of multiple domain-specific variants on resource-constrained infrastructure, while maintaining competitive downstream task performance.

via “fine-tuning and instruction-tuning adaptation”

text-generation model by undefined. 1,00,18,533 downloads.

Unique: Qwen3-8B's instruction-tuned variant provides a strong baseline for further adaptation, reducing the data requirements for domain-specific fine-tuning compared to starting from a base model. The 8B size enables LoRA fine-tuning on consumer hardware (RTX 4090) with acceptable training times (hours vs. days).

vs others: Smaller than Llama 70B, enabling LoRA fine-tuning on single 24GB GPUs with 2-3x faster training, while maintaining instruction-following quality comparable to larger models

via “base model fine-tuning with instruction-aligned weights”

text-generation model by undefined. 51,86,179 downloads.

Unique: Qwen3-1.7B represents a specific instruction-tuning checkpoint derived from Qwen3-1.7B-Base, with explicit versioning and reproducibility through safetensors format. The model is positioned as a direct alternative to base-model-only deployment, offering immediate instruction-following without requiring users to perform their own SFT.

vs others: More instruction-aligned than Qwen3-1.7B-Base with minimal parameter overhead; more efficient than fine-tuning a base model from scratch for teams with limited compute resources.

Hunyuan-A13B is a 13B active parameter Mixture-of-Experts (MoE) language model developed by Tencent, with a total parameter count of 80B and support for reasoning via Chain-of-Thought. It offers competitive benchmark...

Unique: Achieves competitive benchmark performance through MoE specialization rather than parameter scaling, allowing different experts to optimize for different task types; Tencent's instruction-tuning approach balances performance across diverse benchmarks within the sparse architecture

vs others: Competitive with Llama 2 13B and Mistral 7B on benchmarks while using MoE for efficiency; likely underperforms dense 70B+ models on complex reasoning benchmarks but offers better cost-performance ratio

via “dual-variant model selection (instruct vs pre-trained base)”

Meta's Llama 3 — foundational LLM for instruction-following

Unique: Ollama distribution includes both instruct and base variants in the same model registry, allowing single-command switching between them without re-downloading or managing separate model files

via “model variant selection with performance-capability trade-offs”

Dolphin-tuned Mixtral — enhanced instruction-following on Mixtral

Unique: Provides two explicit model variants with documented size and context differences, enabling hardware-aware selection; no automatic scaling or model selection logic, requiring manual user choice

vs others: Clearer variant strategy than some models (e.g., Llama 2 with many undocumented variants), but with less guidance than managed services that automatically select model size based on workload

via “base model selection and catalog browsing”
