Total breakdown on how to take your OPUS 5 to a GOD-MODE level that works as an army of teammates x.com/i/article/2080…

We removed ~80% of the Claude Code system prompt for our newest models, this is what we've learned about writing system prompts, skills and Claude.MDs for them. x.com/i/article/2080…





claude opus 5 vs fable 5 vs gpt 5.6 sol vs kimi k3 @AnthropicAI released claude opus 5 today. per the announcement, it's "a thoughtful and proactive model that comes close to the frontier intelligence of claude fable 5 at half the price." key facts from the release: • priced at $5/mtok input, $25/mtok output – unchanged from opus 4.8 • anthropic reports it as state-of-the-art on frontier-bench v0.1 (43.3%), gdpval-aa v2 (1861), arc-agi-3 (30.2%), zapier automationbench (26%) and osworld 2.0 (70.6%) • per the same release, it stays behind mythos 5 on cybersecurity, and behind fable 5 on parts of agentic coding (deepswe 68.8 vs sol's 72.7, frontiercode 53.4 vs fable's 53.5) • runs at max thinking effort by default; a fast mode is offered at ~2.5x speed for 2x the price. our runs used the standard setting our test – 3 prompts, single-file html, @threejs, fully procedural, no assets. each has a small fire button (web audio gunshot + muzzle flash + recoil + ejected brass) and a disassemble toggle that explodes the gun into labelled parts and rebuilds it: 1. 5.56 m4 carbine – collapsible stock, safe·semi·burst lower, quad-rail with r14–r28 panel numbers, aimpoint red-dot, vertical foregrip, folding bipod, a2 flash hider, breaks into 10 parts 2. glock 18c – select-fire machine pistol, ported 18c compensator slots, "glock 18c / austria 9x19" roll-marks, extended 33-round mag, field-strips into slide, ported barrel, recoil spring, frame, mag 3. steyr tmp – ribbed polymer housing, threaded barrel, integral forward vertical foregrip, canted translucent 30-round mag ran on @aimlapi results: - cost #1 gpt 5.6 sol – $1.26 #2 kimi k3 – $3.60 #3 opus 5 – $6.22 #4 fable 5 – $8.12 - tokens #1 gpt 5.6 sol – 36,554 #2 fable 5 – 120,203 #3 opus 5 – 137,093 #4 kimi k3 – 196,596 - lines of code #1 opus 5 – 2,738 #2 gpt 5.6 sol – 2,432 #3 kimi k3 – 1,907 #4 fable 5 – 1,764 - generation time #1 gpt 5.6 sol – 7.8 min #2 fable 5 – 23.5 min #3 opus 5 – 24.8 min #4 kimi k3 – 93.8 min observations: • opus 5 wrote the most code and shipped the best-looking guns – the two go together. 2,738 lines, almost no boilerplate, and it beat fable at 3/4 of fable's price. all 3 models render, all 3 disassemble reliably • it is the only model that respected the black-on-black problem. its studio env is a narrow overhead strip with a comment explaining why ("narrow + long beats big + square here"), and parts separate by roughness, not colour – slide 0.44, ribs 0.52, grip 0.86. that is why the lighting reads like a product shot • the steyr ribbing and m4 proportions are the best in the test. the ribs are real half-buried cylinders merged into one geometry, each catching a single specular line – not a bump map. thin barrel, slim quad-rail, correct 84cm scale, all computed from named stations, not eyeballed • price per 100 shipped lines – gpt sol $0.052, kimi $0.189, opus $0.227, fable $0.460. opus buys frontier-grade detail for half of fable's per-line rate opus 5's code quality: upsides: - it engineers instead of eyeballing. everything is built to real-world scale (m4 = 84cm), the rail teeth sit at the exact 1cm pitch a real picatinny rail uses, and the steyr's ribbing is actual 3d geometry catching a specular line, not a bump texture faking it - it caught a classic three.js trap the others didn't – the bevel on extruded shapes quietly inflates the silhouette, so it pre-corrected every surface constant so decals and ribs sit flush instead of floating or z-fighting downside: - one systemic bug: every left-side engraving renders mirrored. roll-marks, the safe·semi·burst selector, the mag numbers – all reversed. single cause, but it hits all three guns opus 5 is the strongest engineer in this field – it saw traps the others walked into and reasoned about physics constants, real-world scale, and sequences instead of guessing follow @thehypedotnews for 24/7 ai news, analysis and breakdowns
