Tutorials, deep dives and product notes — built for developers.
GPT-5.5 dominates agentic coding (+14.2 Terminal-Bench, +4.4 SWE-bench Pro). Gemini 3.1 Pro wins on price (2.5× cheaper), reasoning (GPQA 94.3%), and multimodal breadth. Real benchmarks, pricing analysis, and a 9-point decision matrix for choosing the right enterprise model.
MiniMax M3 (59.0% Pro, $1.20/1M, 1M ctx) vs GLM 5.1 (58.4%, $4.40/1M, 200K ctx). Both Huawei Ascend, both MIT, both Chinese. 0.6 pts apart on Pro. M3 leads context + multimodal. GLM leads reasoning + CyberGym #1 + pure MIT + $3/mo plan. Full comparison.
MiniMax M3 (59.0% SWE-bench Pro, $1.20/1M) beats GPT-5.5 (58.6%, $30/1M) on the hardest coding benchmark at 25× less cost. But GPT-5.5 dominates Terminal-Bench (+16.7), OSWorld (+8.7), GPQA and HLE. 1M context, native video, MSA architecture, open-weight vs proprietary. Full comparison.
Anthropic's new Mythos-class Fable 5 (80.3% SWE-bench Pro, $50/1M) vs the outgoing flagship Opus 4.8 (69.2%, $25/1M). Fable 5 dominates every benchmark — but costs 2× more, hallucinates more, and sometimes falls back to Opus 4.8 anyway. Full 30-benchmark comparison.
AI can now generate UML class diagrams, flowcharts, ERDs, and architecture diagrams from your code in under 60 seconds. We break down the three approaches — diagrams-as-code, sandbox execution, and direct image generation — and show which actually produces accurate, production-ready diagrams. 90+ languages supported.
The complete Claude Fable 5 review. Mythos-class for everyone. 80.3% Pro, 88.0% Terminal-Bench, 93.9% Verified. Stripe's 50M-line migration in a day. Karpathy: "major-version-bump-deserving." Simon Willison: "a beast." Safety classifiers, $10/$50 pricing, and why this is the biggest step toward AGI yet.
Claude Fable 5 ($50/1M) vs GPT-5.5 ($30/1M). Fable 5 leads all 8 coding benchmarks (+11.8 avg). GPT-5.5 counters with lower price and Batch/Flex at $15. 5× better Pro value from Fable 5. The definitive head-to-head comparison.
Claude Fable 5 ($50/1M) vs GPT-5.5 Pro ($180/1M). Fable 5 leads all 8 coding benchmarks by +11.8 pts avg. GPT-5.5 Pro fights back on BrowseComp (90.1%) and FrontierMath (39.6%) via parallel compute — but has no published Pro coding scores. Updated with separate GPT-5.5 Pro benchmarks.
Claude Fable 5 leads every benchmark (80.3% Pro, 88.0% Terminal-Bench, ~87% Multi). Now the undisputed #1 for Go coding across all workflows. Updated June 9, 2026.

DeepSeek V4 Flash ($0.28/1M, MIT) vs Gemini 3 Flash ($3.00/1M). Flash leads Pro (+3.0), GPQA (+6.9), MCP Atlas (+7.0). Gemini leads OSWorld (65.1%), multimodal input, and Toolathlon. 10.7× price gap. Two Flash-tier models, zero overlap.
DeepSeek V4 Flash ($0.28/1M, MIT) vs GPT-5.4 Mini ($4.50/1M). Mini leads SWE-bench Pro (+1.8) & Terminal-Bench (+3.1). Flash leads LiveCodeBench (91.6%), HLE (+3.6), and is 16× cheaper. The budget coding tier has never been more competitive.
