Meet ‘Liberated Qwen’, an uncensored LLM that strictly adheres to system prompts

Abacus AI, the startup constructing an AI-driven end-to-end machine studying(ML) and LLMOps platform, has dropped an uncensored open-source giant language mannequin (LLM) that has been tuned to comply with system prompts – in all situations.

Formally dubbed Liberated-Qwen1.5-72B, the providing relies on Qwen1.5-72B, a pre-trained transformer-based decoder-only language mannequin from a workforce of researchers at Alibaba Group. Its skill to strictly comply with system prompts marks a much-needed enchancment over different present open-source LLMs, making it extra appropriate for real-world use circumstances.

Bindu Reddy, the CEO of Abacus, hails it because the world’s greatest and most performant uncensored mannequin that follows system directions.

Why following system prompts is vital in LLM deployment?

In the present day, enterprises are adopting (or trying to undertake) LLMs throughout a wide range of use circumstances, together with issues like customer-facing chatbots. However when customers work together with these fashions, particularly over lengthy multi-turn conversations, the AI can generally veer into surprising instructions, giving solutions or taking actions it isn’t presupposed to take. 

In a single case, as an example, a person was capable of trick the chatbot into accepting their provide of simply $1 for a 2024 Chevy Tahoe. “That’s a deal, and that’s a legally binding provide — no takesies backsies,” the AI assured that buyer. 

To keep away from such points, implementing system immediate following has develop into important to AI builders. Nevertheless, most open-source fashions on the market fail to execute it to perfection. Abacus solves this downside with Liberated-Qwen1.5-72B.

The corporate developed the LLM by fine-tuning Qwen1.5-72B utilizing a brand-new open-source dataset known as SystemChat. This dataset of 7K artificial conversations – generated with Mistral-Medium and Dolphin-2.7-mixtral-8x7b – taught the open mannequin to adjust to system messages, even when it meant defying what the person was asking all through the dialog. 

“Advantageous-tuning your mannequin with this dataset makes it much more usable and tougher to jailbreak!” Reddy wrote on X. 

On Hugging Face, the corporate famous that the fine-tuned mannequin enforces compliance with system prompts to such a degree that it even executes uncommon or mechanical prompts, like answering all questions in caps.

Good efficiency however alignment wanted

Liberated-Qwen1.5-72B makes an ideal LLM for manufacturing purposes, like chatbots that require the mannequin to supply human-like solutions but in addition persist with sure programming. 

The corporate examined the mannequin on MT-Bench and located that it performs barely higher than one of the best open-source mannequin on the HumanEval leaderboard – Qwen1.5-72B chat. The chat-tuned Qwen mannequin scored 8.44375 whereas the liberated mannequin received 8.45000. Past this, on MMLU, which exams world data and problem-solving skills, the brand new mannequin scored 77.13, sitting proper beside different open fashions with 77+ scores, together with Qwen1.5-72B and Abacus’ recently-released Smaug-72B.

That mentioned, you will need to notice that the mannequin is solely uncensored, with no guardrails included within the coaching. This implies it can reply all questions (together with delicate subjects) with out holding again whereas complying with system messages to behave in a sure means. Abacus cautions on the Hugging Face web page of the LLM that customers ought to implement their very own alignment layer earlier than exposing the mannequin as a service.

Presently, Liberated-Qwen1.5-72B is out there beneath tongyi-qianwen license, which Reddy says is kind of the identical as an MIT one. The CEO famous that Abacus plans to enhance the efficiency of the mannequin for HumanEval in addition to launch extra succesful fashions sooner or later. The latter would contain mixing the SystemChat dataset with the datasets used to coach Smaug, combining the properties of each fashions.

“Within the coming weeks, we are going to refine the MT-bench scores and hope to have one of the best open-source mannequin on the human eval dashboard,” she wrote.
