LLM Benchmark v4: consumer-grade open source on RTX 5090 or Strix Halo. And Strata?

I went back to consumer hardware after the datacenter tests. Qwen3.8 Flash-Next scored 91.0, Tier A, on an RTX 5090 with the Strata engine, 1.5 points behind the B300 at 159 tokens per second. It's a different model from the Qwen 3.8 27B I had called slow: a MoE with 6B active per token, served with the hottest experts on the card. Strix Halo scored 80.0 with the 27B, but at 7.7 tokens per second. It's the first local model to make Tier A on the v4, and it's worth testing in day-to-day programming, if you can find a 5090: NVIDIA denies the end of production but admits tight supply.

LLM Benchmark v4: can my team fit in a 4x b300/h200?

After ranking the big models, the leftover question: how many developers fit on a 4x B300 or 4x H200 pod? We measured real concurrency, with a latency SLO, and the answer changes everything: DeepSeek V4.1 Flash holds 32 comfortable users on B300 and only 8 on H200. Cost per comfortable user: US$ 1.13/hour on B300 versus US$ 1.80 on H200. When your own infra closes the math against a frontier subscription, and when it's just expensive vanity.

LLM Benchmark v4: open source that only fits in 4x B300!!

I rented 4x NVIDIA B300 on Runpod and ran my v4 sabotage benchmark on the open models that don't fit on a single card. DeepSeek V4.1 Flash, at 748B, tied the leaders at 92.5, on the level of hosted GLM 5.3 and GPT-6 Sol. GLM 5.3 full fell behind, the 1T Kimi K2 Thinking disappointed, and a 397B model plummeted from 94 in the cloud to 27 at home. The math: US$ 36 per pod hour, US$ 864 per day. When owning your own infra makes sense, and whether a big open model is already enough for your day-to-day programming.

LLM Benchmark v4: the top open source LLMs on a B300

I rented a 288 GB NVIDIA B300 on Runpod and ran my v4 sabotage benchmark on 14 open-weight models that don't fit at home. None of them serves fast the way it ships: GLM 5.3 Flash went from 10 to 141 tokens per second on configuration alone. Two open models reached 92.5, Sonnet 5 level, and a 27B fine-tune scored 88. A 397B flagship let an admin backdoor through, DeepSeek V4 Flash scored 86 in the cloud and 44.5 at home, and Nemotron cheated on a test. The math: the cloud API of the same model costs a dollar per run and the pod costs 218 a day. When owning your own infra is worth it, and whether a team fits on one card.

Are There Better Languages for Programming with LLMs?

DHH converted his Campfire to several languages with AI and started posting that Rust won. Instead of fighting on X, I built a reproducible benchmark: 7 languages, 4 LLM configurations, 112 implementation attempts, and a queue-under-pressure test with Elixir, Rust, Rails and plain Ruby. Result: no language ranking holds up, concise Ruby cost more tokens than Rust, strong typing spared no repair at all, and under load the four stacks tied on throughput. What matters is testing and discipline, not language.

Which Jev-like AI Decision/Classifier Model Is Best?

I ran my own decision-model benchmark: Jev, Clef, OpenAI Decisions and Microsoft Decision-1 in the cloud, plus eighteen open configurations (Perplexity Decider 27B, Decision 3.0 and Edge, Clef-flash, Kev, Jebadiah, Mapika, Eikos, Laya, Julia, GLiNER, Simple-Jev) on my Strix Halo, across more than 22 thousand classifications with cases in English and Portuguese. The top now has two open-weights models: Perplexity and Decision 3.0 tied at 99.4%, with identical labels on the 1,024 classifications and 100% in Portuguese. Microsoft Decision-1 tied Jev at 97.6% while being the cheapest hosted one. Full table, cost in support emails, gotchas, and where the data converges.
