A roundup of mid-tier open-weight model releases around April Fools 2026, headlined by Arcee's Trinity-Large-Thinking — a 400B/13B-active MoE model with Apache 2.0 weights, strong agentic benchmarks (#2 on PinchBench behind Opus 4.6), and explicit developer/enterprise distillation support. Also covers Z.ai's GLM-5V-Turbo vision-coding model and other releases. Most major labs held back launches given the date.
