GigaToken Accelerates BPE With Rust, SIMD, and Direct File I/O, Reaching 24.53 GB/s in a GPT-2 Tokenization Benchmark

The open-source GigaToken 0.9.0 project reoptimizes pre-tokenization, BPE merging, and the data input path, claiming a 989× speedup over Hugging Face Tokenizers on a dual-socket, 144-core AMD EPYC server. Its top result depends on the native API, an 11.9 GB corpus batch, and highly parallel hardware, and cannot be directly extrapolated to short online requests.

Solar Open 2 Supports a Million-Token Context with Hybrid Linear Attention, Activating Just 15B of Its 250B MoE Parameters per Token

South Korea’s Upstage has released Solar Open 2 for long-horizon agents, combining a 250-billion-parameter MoE, hybrid attention, and a 1-million-token context window in a single model. The company says the quantized model can be deployed on two NVIDIA H200 GPUs, though current evidence for its performance and long-context stability comes primarily from the team’s own testing.

SWE-Pruner Pro Reads Coding Models’ Hidden States Directly, Cutting Agent Tokens by Up to 39%

SWE-Pruner Pro replaces a separate classifier with a lightweight prediction head that uses a coding agent’s internal representations to decide whether to retain each line of tool output. Tests with two open MoE models across four multi-turn benchmarks showed token savings, but the method requires inference-server modifications, and some quality gains have yet to be reproduced.
