What is the best local LLM?
Local means you run the weights. This page still shows hosted API prices because most teams try a host first. Rank GPQA, HLE, and SWE-bench among open weights, then check whether your GPU can actually load the checkpoint.
Llama vs Qwen vs DeepSeek
Qwen vs Llama is the comparison people type. DeepSeek and Kimi belong in the same list. Closed GPT and Claude rows are filtered out here on purpose. Sort the table. Brand threads on Reddit go stale in a week.

Should I always pick the #1 GPQA model?
Not automatically. Kimi K3 leads GPQA, but a cheaper scored model can be the better production choice if the quality gap is small. Use the table to weigh GPQA against input/output price, context window, and related evals.
How often is the Open Source leaderboard updated?
Scores and API prices on this page are refreshed from published evals and provider rates. The snapshot is labeled August 20, 2026. Treat it as a current index, not a one-off blog post.
What is the best local LLM?
As of August 20, 2026, Kimi K3 ranks first among open-weight models on GPQA at 93.5%. Hosted API pricing is $3.00/M input and $15.00/M output. Local means you run the weights. The API still bills tokens.
Does open source mean free to run?
Weights can be free while the hosted API still bills tokens. This table uses the public API price we track, not your self-host electricity cost.
Are closed models hidden on this page?
Yes. GPT, Claude, and Gemini are filtered out so the ranking is only open-weight models.
Llama vs Qwen: which open source model is better?
Llama vs Qwen depends on the eval and the size. Qwen often leads public reasoning and coding tables in this index. Llama still wins on distribution and tooling. Sort this open-weight board instead of picking a brand.
Does open source mean the API is free?
No. Open weights can be free to download. Hosted Llama, Qwen, DeepSeek, and Kimi APIs still bill tokens. This table uses the public hosted rate, not your electricity bill.
Are GPT and Claude hidden here?
Yes. This ranking is open-weight only. Closed models stay on the overall and coding boards.
What is the best open source coding LLM?
Sort this board by SWE-bench or open the coding board and filter to open weights. DeepSeek, Qwen, Kimi, and Llama rotate. Confirm the host in the row. Same weights, different APIs, different bills.
