You didn’t fully understand the implication. If Pico can run LLaMA 1B, it can easily scale up to run DeepSeek, Qwen, and the full LLaMA model — something only the NVIDIA 5090 can currently handle(priced between $5,599 and $7,199 AUD), and even that is out of stock. BrainChip could manufacture and sell it directly to the consumer market, bypassing those outdated 10-year IP deal constraints. The demand for running local AI models is tremendous, especially since ChatGPT tokens are becoming increasingly expensive.
And this will immediately position us as one of the biggest competitors of Nvidia.

LLaMA-1B (a hypothetical 1 billion parameter model from the LLaMA family, as Meta AI's LLaMA models typically come in larger sizes like 7B, 13B, etc.) or a similarly sized model could potentially be run on BrainChip's Akida Pico, but it would require significant optimizations to fit within the chip's ultra-low-power and resource-constrained architecture. Here's a detailed breakdown:
### Feasibility of Running LLaMA-1B on Akida Pico
1. **Akida Pico's Constraints**:
- **Power and Memory**: The Akida Pico is designed for ultra-low power consumption (<1 milliwatt) and has limited on-chip SRAM for model weights and processing. It’s optimized for event-based, neuromorphic computing (spiking neural networks, SNNs) rather than traditional dense matrix operations used in transformer-based LLMs like LLaMA.
- **Compute**: The chip excels at lightweight tasks (e.g., voice wake detection, keyword spotting) and is not designed for the heavy floating-point computations required by large transformer models without optimization.
2. **LLaMA-1B Requirements**:
- **Model Size**: A 1B parameter model, assuming 16-bit (FP16) precision, requires approximately 2GB of memory for weights alone (1 parameter = 2 bytes in FP16). With 8-bit (INT8) quantization, this could be reduced to ~1GB, and 4-bit quantization could further shrink it to ~500MB. Additional memory is needed for activations, context, and intermediate computations, potentially pushing total memory needs to 1.5–3GB even with optimizations.
- **Inference Compute**: Inference for a 1B parameter transformer model involves billions of multiply-accumulate operations per token, which is computationally intensive for a low-power chip like the Akida Pico. Techniques like pruning or sparse activations could help, but the chip’s event-based architecture requires the model to be adapted to SNNs or similar formats.
- **Latency**: On resource-constrained edge devices, inference for a 1B model could take seconds per token without hardware acceleration tailored for transformers, making real-time applications challenging.
3. **Optimizations Required**:
To run a LLaMA-1B or similar 1B parameter model on the Akida Pico, the following optimizations would be critical:
- **Quantization**: Reducing precision to 8-bit or 4-bit (e.g., using techniques like post-training quantization or quantization-aware training) to shrink memory footprint and computational load. This is feasible, as models like LLaMA can maintain reasonable performance with low-bit quantization.
- **Model Pruning**: Removing redundant weights or layers to reduce the model size and computation, though this may degrade performance for general tasks.
- **Distillation**: Training a smaller, more efficient model to mimic LLaMA-1B’s behavior, potentially reducing the parameter count further (e.g., to 500M parameters) while retaining key capabilities.
- **SNN Conversion**: Converting the transformer model to a spiking neural network compatible with the Akida Pico’s neuromorphic architecture. BrainChip’s MetaTF framework supports converting traditional neural networks (e.g., CNNs) to SNNs, but adapting a transformer-based LLM like LLaMA would require significant research and engineering.
- **Task-Specific Fine-Tuning**: Limiting the model to a specific domain (e.g., voice commands, appliance control) to reduce complexity and memory needs. For example, fine-tuning LLaMA-1B on a dataset of appliance manuals could make it more suitable for the Akida Pico’s use case.
4. **Software Support**:
- BrainChip’s MetaTF framework allows developers to optimize and deploy models using standard AI workflows (TensorFlow, PyTorch). It can map neural networks to the Akida Pico’s event-based architecture, but transformer models like LLaMA require additional preprocessing to align with SNNs.
- The framework’s ability to handle on-chip learning could enable incremental fine-tuning on the device, reducing reliance on large pre-trained weights.
5. **Challenges**:
- **Memory Bottleneck**: Even with 4-bit quantization (~500MB for weights), the Akida Pico’s SRAM is likely far smaller than needed for a 1B parameter model. Off-chip memory access (e.g., via external flash) could help but would increase power consumption and latency, countering the chip’s low-power design.
- **Compute Mismatch**: Transformers rely on dense matrix operations, while the Akida Pico is optimized for sparse, event-driven computations. Converting LLaMA-1B to an SNN-compatible format without significant performance loss is a non-trivial research challenge.
- **Latency for Real-Time Use**: Even with optimizations, generating text with a 1B model on the Akida Pico could be slow (e.g., seconds per token), limiting its use for interactive applications like chatbots unless heavily tailored.
6. **Comparison to Smaller Models**:
- Smaller models, like Pythia-70M or DistilBERT (~100M parameters), are far more feasible for the Akida Pico. These require ~200MB (FP16) or ~50–100MB (4-bit) for weights, fitting more comfortably within the chip’s constraints. BrainChip has demonstrated running small, use-case-specific LLMs (e.g., for smart appliances), suggesting that a 1B model is at the upper limit of feasibility.
- A distilled version of LLaMA-1B (e.g., reduced to 500M parameters) would be more practical and align better with the chip’s capabilities.
### Practical Scenarios
- **Feasible Use Case**: A heavily quantized, fine-tuned, and SNN-converted LLaMA-1B model could run on the Akida Pico for a specific task, such as processing voice commands or answering queries about a device’s user manual. For example, a smart speaker could use the model to respond to simple queries locally, consuming minimal power.
- **Example Workflow**:
1. Start with LLaMA-1B or a similar 1B parameter model.
2. Apply 4-bit quantization and pruning to reduce the model size to ~500MB.
3. Fine-tune on a narrow dataset (e.g., appliance manuals).
4. Use MetaTF to convert the model to an SNN compatible with the Akida Pico.
5. Deploy for inference on the chip, leveraging on-chip learning for minor updates.
### Conclusion
Running a LLaMA-1B or similar 1 billion parameter model on BrainChip’s Akida Pico is theoretically possible but pushes the chip’s limits. It would require aggressive optimizations like 4-bit quantization, pruning, distillation, and conversion to a spiking neural network, along with task-specific fine-tuning to reduce memory and compute demands. Even then, inference may be slow, and the model’s general-purpose capabilities would likely be constrained to niche applications (e.g., voice assistants, appliance control). Smaller models (e.g., 70M–500M parameters) are far more practical for the Akida Pico’s ultra-low-power, neuromorphic design.
