REAP-pruned BF16 variant of MiniMaxAI/MiniMax-M2.7. Uses Cerebras's REAP methodology with a 6-dataset agentic calibration mix to preserve tool-use, code-generation, and reasoning capabilities while reducing expert count by 25%.
This is the intermediate BF16 artifact — the REAP'd model before quantization. Use this if you want to apply your own quantization scheme. For direct single-Spark deployment on NVIDIA DGX Spark (GB10) and Blackwell-family hardware, use the NVFP4 variant: saricles/MiniMax-M2.7-REAP-172B-A10B-NVFP4-GB10.
"Which experts survive pruning depends on which activations the calibration data triggers." If you calibrate on pure chat, experts specialized for code / tool-calling / math get scored low and pruned — the resulting model loses those capabilities. This mix is chosen to preserve capabilities for agent-framework deployment (OpenClaw, Aider, Claude Code-style assistants):
At 340 GB this does not fit on a single consumer GPU. For serving, either run multi-GPU tensor-parallel or apply a quantization (NVFP4, AWQ, GPTQ, etc.). For GB10 / Blackwell deployment, consider the NVFP4 variant.
When to choose this BF16 variant vs. full MiniMax-M2.7
Use this REAP BF16 if: you want a 25%-smaller MoE model with preserved agentic/coder capabilities, or you plan to apply your own quantization (AWQ, GPTQ, GGUF, different NVFP4 recipe).
Use MiniMaxAI/MiniMax-M2.7 if: you need the full 256-expert model and can afford the larger deployment footprint.
Target Hardware
This is BF16 — hardware-agnostic. Any inference stack supporting custom transformers modeling code + BF16 safetensors (transformers, vLLM, TGI, etc.) can load it, given enough aggregate GPU memory.
Calibration notes (2026-04-17 correction)
During the REAP scoring pass that produced this artifact, the dataset extractor silently dropped texts from SWE-bench/SWE-smith-trajectories because that dataset stores the messages field as a JSON-encoded string (not a list-of-dicts, as several other datasets in the mix). Our extractor iterated the string as characters, found no dict entries, and collected zero usable texts from SWE-smith.
Net effect on this artifact: 5 of the 6 documented calibration datasets contributed to expert-importance scoring — evol-codealpaca, xlam-function-calling, and the three Mixture-of-Thoughts configs (code, math, science). SWE-smith-trajectories did NOT contribute, contrary to the original claim in this card.
Fix: the recipe script reap-bf16-agentic.py has been updated to json.loads() string-encoded messages fields, plus a per-dataset assertion that fails the run if any dataset yields zero texts. Future REAP variants will include SWE-smith as originally intended.
Practical implication: agentic tool-use preservation still benefited from xlam-function-calling. What's missing is the specific activation pattern from multi-turn SWE-agent trajectories (long-horizon read→run→patch→verify chains). If you run this model in long-chain SWE-style agents and see activation-clipping artifacts, that's why — please file an issue.
Calibration-mix design: in the spirit of the multi-domain calibration mix Cerebras recommends for REAP — the specific configs (MoT code/math/science split, SWE-smith tool split) are optimized for agentic workloads
