The Anthropic Console is where developers build with Claude. Features include the Workbench for prompt engineering, evaluation tools for testing outputs, and API key management. The prompt caching and batch API features reduce costs significantly.

Bonsai-8B is PrismML's latest model in their BitNet-inspired lineage — an 8.2B parameter language model that has been quantized end-to-end to true 1-bit precision (weights stored as -1 or +1), compressing the entire model to just 1.15 GB. That's roughly 12-14x smaller than a standard FP16 equivalent. Unlike post-training quantization hacks that lose substantial quality, PrismML trained Bonsai-8B with 1-bit arithmetic baked into the forward pass from the start. Benchmark results are competitive for the size class: 63.8 on MMLU, 72.1 on HellaSwag, and 54.2 on GSM8K — while running at 131 tokens/sec on an M4 Pro MacBook and 44 tokens/sec on an iPhone 17 Pro Max. That makes it the fastest locally-runnable 8B model in its weight class on Apple Silicon. The MLX-optimized weights are available on Hugging Face today under Apache 2.0. The significance goes beyond benchmarks. Getting a capable open-weight model to run at interactive speeds on consumer hardware — with no API key, no GPU, no cloud dependency — is a meaningful step toward truly private, offline AI. This follows PrismML's earlier "Ternary Bonsai" (1.58-bit) but represents a cleaner binary architecture that's easier to accelerate on custom silicon.
Reviewer scorecard
“The Workbench is the best prompt engineering environment available. Test prompts, compare models, and see token counts in real-time. Essential for any Claude API project.”
“131 tokens/sec on M4 Pro at 1.15 GB is genuinely impressive — I can embed this in a macOS app without any cloud dependency, no rate limits, no privacy concerns. The Apache 2.0 license means I can ship commercial products on top of it. This is the edge AI story I've been waiting for.”
“Clean, functional, does what it needs to. The evaluation tools are underrated — most developers ship prompts without testing. This makes testing easy.”
“63.8 on MMLU is respectable but it's still noticeably behind mid-range cloud models on reasoning tasks. The GSM8K score of 54.2 means it'll fumble multi-step math that users expect to just work. Until 1-bit gets to 70B scale, it's a neat demo that falls short in production use cases where quality matters.”
“Anthropic is building the developer platform, not just the model. Console + Claude Code + Agent SDK — they want developers building on Claude, not just chatting with it.”
“The trajectory here is what matters: 1-bit models are getting faster to train and competitive faster than expected. When custom Apple Neural Engine kernels land for BitNet-style weights, we'll see 200+ tokens/sec on a phone. Bonsai-8B is the proof-of-concept that makes that future feel real.”
“I've been looking for something I can embed in a creative writing or brainstorming app that doesn't require an internet connection. At 44 tokens/sec on iPhone, Bonsai-8B is finally fast enough to not break the creative flow. The 'no account required' angle is a genuine selling point for privacy-conscious users.”
