Explore GPT-OSS: OpenAI's Revolutionary Open-Source AI Model
Fueling Creativity: OpenAI's GPT-OSS – Accessible, Swift, and Entirely Customizable.

Hi! What can I help you?
What is GPT-OSS?
GPT-OSS represents OpenAI's newest open-weight lineup, their initial open-source offering post-GPT-2. It employs a Mixture-of-Experts (MoE) framework to achieve exceptional efficiency alongside reduced parameter activation.
Open-Source Intelligence Engine:
Includes models like gpt-oss-120b and gpt-oss-20b, outstanding in demanding activities such as programming, calculations, and analytical challenges, freely obtainable for modification.
On-Premise and Resource-Smart Operation:
Tailored for everyday gadgets like notebooks and graphics cards, granting access to professional AI without relying on external servers.
Innovation for Developers:
Distributed via Apache 2.0, permitting adjustments, refinements, and implementations across diverse scenarios, from individual projects to expansive infrastructures.
What's New in GPT-OSS?
Mixture-of-Experts Optimization
Lowers resource demands while preserving close-to-leading-edge reasoning, facilitating quicker processing on regular equipment.
Device-Based Intelligence
Enables execution on personal computers and consumer GPUs, providing secure, immediate AI interactions independent of online connections.
Embedded Functions and Scope
Offers 128K token capacity, script running, and online lookup to boost practical applications.
Key Features of GPT-OSS
Expansive Visions:
Mixture-of-Experts Design Utilizes MoE to engage only essential elements, offering streamlined, premium reasoning comparable to closed systems like o4-mini.
Independent Freedom:
Device-Level Processing Operate gpt-oss-20b on typical notebooks or graphics units for confidential, rapid AI handling free from external expenses or delays.
Logic Evolution:
Sophisticated Step-by-Step Thinking Thrives in sequential operations, compiling ideas for precise results in development, equations, and deduction.
Utility Boost:
Built-In Enhancements Incorporates features such as code running and internet querying, improving efficiency in dynamic situations.
Adaptation Hub:
Tuning Flexibility Apache 2.0 permits straightforward modifications for targeted areas, spanning studies to corporate tools.
Versatile Flames:
128K Input Capacity Manages large-scale data for intricate dialogues and evaluations while maintaining consistency.
Use Cases for GPT-OSS
Programming Wizards: Streamlining Coding Processes
Embed GPT-OSS in development environments for instant script creation, error correction, and enhancements, accelerating tech initiatives.
Inquiry Innovators: Advancing Academic Investigations
Leverage its analytical strength to formulate theories, review datasets, and model trials in disciplines like life sciences and mechanics.

GPT-OSS vs Other Models
Feature/Model | GPT-OSS (120b/20b) | Meta Llama 3 | Mistral AI Models | DeepSeek V2 |
---|---|---|---|---|
Architecture | MoE for optimization | Standard Transformer | MoE options | MoE with refinements |
Reasoning Capability | Close to top benchmarks like MMLU, superior in sequential logic | Solid yet behind in intricate chains | Effective for languages, weaker in core analysis | Strong in scripting, prone to inaccuracies |
On-Device Support | Tuned for notebooks/GPUs (20b on basic setups) | Demands ample memory | Resource-friendly but scope-restricted | Requires premium hardware |
Context Length | 128K tokens | Up to 128K in bigger versions | Differs, max 32K | Up to 128K |
How to Use GPT-OSS
Launching GPT-OSS is simple. Here's a guide to set it up on your device:
Acquire the Model
Head to OpenAI's site or Hugging Face to grab gpt-oss-20b or 120b files. Verify your setup aligns with specs (e.g., 80GB GPU for 120b).
Set Up a Platform
Employ Ollama, Hugging Face Transformers (v4.55+), or LM Studio for quick installation. Use pip install transformers as necessary.
Execute On-Site
Initialize with something like ollama run gpt-oss-20b and begin interactions through API or UI.
Connect and Refine
Link to your application using OpenAI-style interfaces, or customize with unique data for niche applications.

gpt-oss series is seriously impressive. I think it's sold me on local ai actually being good. previous models disappointed me. deepseek was good, but incoherent (in my experience). the performance out of 20b is insane and good for 99.99% of people.

Of course the new gpt-oss are free & can run on your laptop… We are about to experience some NEXT LEVEL data mining shit anytime now 😅. One small step for mankind, one GIANT loop for AI

The new gpt-oss 20b model is awesome, but at least on a base M3 macbook, it runs extremely slow, and isn't functionally useable. 1.17 tokens/s. They claim it can run on 'most laptops' but at least in it's current state, it's too slow.

Tried gpt-oss in both Cursor and Cline. (First impressions) Tool-calling didn't get anywhere. In asking mode you get incredible fast answers but 1/3 requests are getting through. It just kept hitting the same API errors or looping forever. Overall, it's not delivering any value for me at the moment. But I'm glad that OpenAI is releasing open-weight models.

According to OpenAI, the new response format ('Harmony') should not be your concern if you are using an API provider or tools like Ollama. From my experience, both the gpt-oss models are REALLY bad at tool calling. Does the implementation differ by provider?

GPT OSS--first impressions: good it reached a limit and couldn't continue from there, normal ig loved how it kept reasoning while figuring out what i needed...for 35 seconds
