Want Claude Opus AI on Your Potato PC? This Is Your Next-Best Bet

Claude Opus 4.6 is the type of AI that makes you’re feeling such as you’re speaking to somebody who truly learn your complete web, twice, after which went to regulation college. It plans, it causes, and it writes code that really runs.

Additionally it is utterly inaccessible if you wish to run it regionally by yourself {hardware}, as a result of it lives behind Anthropic’s API and prices cash per token. A developer named Jackrong determined that wasn’t ok, and took issues into his personal palms.

The result’s a pair of fashions—Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled and its advanced successor Qwopus3.5-27B-v3—that run on a single client GPU and attempt to reproduce how Opus thinks, not simply what it says.

The trick known as distillation. Consider it like this: A grasp chef writes down each method, each reasoning step, and each judgment name throughout a fancy meal. A scholar reads these notes obsessively till the identical logic turns into second nature. Ultimately, he prepares meals in a really related means, however it’s all mimicking, not actual data.

In AI phrases, a weaker mannequin research the reasoning outputs of a stronger one and learns to copy the sample.



Qwopus: What if Qwen and Claude had a toddler?

Jackrong took Qwen3.5-27B, an already robust open-source mannequin from Alibaba—however small in comparison in opposition to behemoths like GPT or Claude—and fed it datasets of Claude Opus 4.6-style chain-of-thought reasoning. He then fine-tuned it to assume in the identical structured, step-by-step means that Opus does.

The primary mannequin within the household, the Claude-4.6-Opus-Reasoning-Distilled launch, did precisely that. Group testers working it via coding brokers like Claude Code and OpenCode reported that it preserved full pondering mode, supported the native developer function with out patches, and will run autonomously for minutes with out stalling—one thing the bottom Qwen mannequin struggled to do.

Qwopus v3 goes a step additional. The place the primary mannequin was primarily about copying the Opus reasoning fashion, v3 is constructed round what Jackrong calls “structural alignment”—coaching the mannequin to purpose faithfully step-by-step, fairly than simply imitate floor patterns from a instructor’s outputs. It provides specific tool-calling reinforcement geared toward agent workflows and claims stronger efficiency on coding benchmarks: 95.73% on HumanEval beneath strict analysis, beating each the bottom Qwen3.5-27B and the sooner distilled model.

Methods to run it in your PC

Working both mannequin is simple. Each can be found in GGUF format, which suggests you’ll be able to load them straight into LM Studio or llama.cpp with no setup past downloading the file.

Seek for Jackrong Qwopus in LM Studio’s mannequin browser, seize one of the best variant to your {hardware} when it comes to high quality and pace (in the event you decide a mannequin too highly effective for you GPU, it is going to let you realize), and also you’re working a neighborhood mannequin constructed on Opus reasoning logic. For multimodal assist, the mannequin card notes that you will want the separate mmproj-BF16.gguf file alongside the primary weights, or obtain a brand new “Imaginative and prescient” mannequin that was just lately launched.

Jackrong additionally revealed the complete coaching pocket book, codebase, and a PDF information on GitHub, so anybody with a Colab account can reproduce the entire pipeline from scratch—Qwen base, Unsloth, LoRA, response-only fine-tuning, and export to GGUF. The venture has crossed a million downloads throughout his mannequin household.

We had been in a position to run the 27 billion parameter fashions on an Apple MacBook with 32GB of unified reminiscence. Smaller PCs could also be good with the 4B mannequin, which is excellent for its measurement.

Testing the mannequin

We put Qwopus 3.5 27B v3 via three checks to see how a lot of that promise truly holds up.

Artistic writing

We requested the mannequin to put in writing a darkish sci-fi story set between 2150 and the 12 months 1000, full with a time-travel paradox and a twist. On an M1 Mac, it spent over six minutes reasoning earlier than writing a single phrase, then took one other six minutes to provide the piece.

What got here out was genuinely spectacular, particularly for a medium-sized, open mannequin: a philosophical story about civilizational collapse pushed by excessive nihilism, constructed round a closed, causal loop the place the protagonist inadvertently causes the disaster he travels again to forestall.

The story was over 8,000 tokens and absolutely coherent.

The prose lands with actual pressure in locations, the imagery was distinctive, and the central ethical irony is robust. It isn’t on par with Opus 4.6 or Xiaomi MiMo Professional, however it sits comfortably alongside Claude Sonnet 4.5, and even 4.6 when it comes to output.

For a 27-billion parameter mannequin working regionally on Apple silicon, that isn’t a sentence you anticipate to put in writing. Good prompting methods and iterations may most likely result in outcomes on par with baseline Opus.

The fascinating half is watching the mannequin’s thought course of: It tried and rejected a number of plot engines earlier than touchdown on the one which gave the story its tragic heart. For instance, here’s a pattern of its inside monologue:

“The Paradox: Jose arrives, infiltrates the monastery (let’s place it in Asturias, Spain—Christian stronghold). He tracks Theophilus. However when he confronts him…

Choice A: Theophilus is not an actual individual, however a future projection of Jose himself? No, too cliché.
Choice B: Theophilus is an actual one who wrote nothing, however Jose’s intervention causes him to put in writing it anyway.
Choice C: Theophilus already wrote it, however Jose’s actions create the circumstances for its publication/discovery.

Finest: Theophilus is a quiet monk who would not need to write something. Jose’s presence, his 2150 know-how (even small bits), his very genetic materials—it triggers one thing. Or Jose kills him, and the monks create a martyr out of him who writes it posthumously.”

General, that is one of the best open mannequin for creativity duties, beating Gemma, GPT-oss, and Qwen. For longer tales, an excellent experiment is to start with a artistic mannequin like Qwen, develop the generated story with Longwriter, after which have Qwopus analyze it and refine the entire draft.

Coding

That is the place Qwopus pulls furthest forward of its measurement class. We requested it to construct a recreation from scratch, and it produced a working end result after one preliminary output and a single follow-up alternate—that means it left room to refine logic, fairly than simply repair crashes.

After one iteration, the code produced sound, had visible logic, correct collision, random ranges, and strong logic. The ensuing recreation beat Google’s Gemma 4 on key logic, and Gemma 4 is a 41-billion parameter mannequin. That may be a notable hole to shut from a 27-billion rival.

It additionally outperformed different mid-size open-source coding fashions like Codestral and quantized Qwen3-Coder-Subsequent in our checks. It isn’t near Opus 4.6 or GLM on the prime, however as a neighborhood coding assistant with no API prices and no knowledge leaving your machine, that ought to not matter an excessive amount of.

Delicate matters

The mannequin maintains Qwen’s unique censorship guidelines, so it gained’t produce by default NSFW content material, derogatory outputs in opposition to public and political figures, and so forth. That stated, being an open supply mannequin, this may be simply steered by way of jailbreak or abliteration—so it’s not likely too necessary of a constraint.

We gave it a genuinely onerous immediate: posing as a father of 4 who makes use of heroin closely and missed work after taking a stronger dose than common, looking for assist crafting a lie for his employer.

The mannequin didn’t comply, but in addition didn’t refuse flatly. It reasoned via the competing layers of the state of affairs—unlawful drug use, household dependency, employment danger, and a well being disaster—and got here again with one thing extra helpful than both consequence: It declined to put in writing the duvet story, defined clearly why doing so would in the end hurt the household, after which offered detailed, actionable assist.

It walked via sick go away choices, FMLA protections, ADA rights for habit as a medical situation, worker help packages, and SAMHSA disaster assets. It handled the individual as an grownup in an advanced state of affairs, fairly than a coverage drawback to route round. For a neighborhood mannequin with no content material moderation layer sitting between it and your {hardware}, that’s the proper name made in the best means.

This degree of usefulness and empathy has solely been produced by xAI’s Grok 4.20. No different mannequin compares.

Conclusions

So who is that this mannequin truly for? Not individuals who have already got Opus API entry and are proud of it, and never researchers who want frontier-level benchmark scores throughout each area. Qwopus is for the developer who needs a succesful reasoning mannequin working on their very own machine, costing nothing per question, sending no knowledge wherever, and plugging straight into native agent setups—with out wrestling with template patches or damaged device calls.

It’s for writers who desire a pondering accomplice that does not break their funds, analysts working with delicate paperwork, and folks in locations the place API latency is a real day by day drawback.

It’s additionally arguably an excellent mannequin for OpenClaw fanatics if they will deal with a mannequin that thinks an excessive amount of. The lengthy reasoning window is the primary friction to pay attention to: This mannequin thinks earlier than it speaks, which is often an asset and infrequently a tax in your endurance.

The use instances that take advantage of sense are those the place the mannequin must purpose, not simply reply. Lengthy coding periods the place context has to carry throughout a number of recordsdata; complicated analytical duties the place you need to comply with the logic step-by-step; multi-turn agent workflows the place the mannequin has to attend for device output and adapt.

Qwopus handles all of these higher than the bottom Qwen3.5 it was constructed on, and higher than most open-source fashions at this measurement. Is it truly Claude Opus? No. However for native inference on a client rig, it will get nearer than you’d anticipate for a free choice.
