Smallest open-weight Base Labs decision model, 2B on Qwen3.5-2B, for high-volume calls

Joey-1 is an open-weight decision model from Baseten (Base Labs) (MIT, 2B parameters): it answers typed questions, such as yes or no, pick one or pick several, with probabilities instead of writing text. It costs $0.01 per million input tokens (Baseten Model APIs), and output is free. JevBench, the main independent benchmark, doesn't list it yet.

- Made by: Baseten (Base Labs)
- Weights: Open, MIT
- Size: 2B
- Where: Baseten Model APIs
- Images: Yes
- Context: 16,384 (max sequence length) on Model APIs; dedicated deployments allow 262K
- Fine-tuning: Available for post-training on Baseten Training Jobs
