Closed-frontier reference (May 2026)
What "API-grade" actually scores right now. Use this as the ceiling — anything local will lag here by some margin, and that's fine for most workflows.
Gemini 3.1 Pro
- HLE44.7%
- Terminal-Bench 280.2%
- SWE-Bench Pro54.2%
- SWE-Bench Ver80.6%
- Aider Polyglot—
- LiveCodeBench91.7%
- GPQA Diamond94.3%
- MMLU-Pro91.0%
Coding: Coding-strong, especially repo-level work with 2M context. Less of a Cursor/Cline default than Claude — Gemini Code Assist users prefer it. Top of leaderboards on GPQA + LCB. Now #7 on OpenRouter coding by volume (120B tokens) — Gemini 3.5 Flash will displace it next month.
Agent: TB2 80.2 makes it agent-grade. Used widely on Google's Agent Builder; less common in Open-Claude/Hermes. Reliable in long Vertex-AI Agent runs (multi-hour).

- MMLU-Pro—
Coding: Codex CLI + GPT-5.5 is the top of Terminal-Bench. r/ChatGPTCoding has shifted to it for daily coding; Cursor users mixed (some prefer Claude Sonnet 4.6 for diff quality).
Agent: Strongest published agent score (TB2 82.0%, re-verified 2026-05-14). Widely used in OpenAI Assistants, AutoGPT-style swarms, and Open-Claude routing. Reliable in 4-8h autonomous sessions.

Coding: Anthropic's 2026-06-30 release: near-Opus intelligence at the old Sonnet price. Terminal-Bench 2.1 jumps to 80.4 (from Sonnet 4.6's 53.4), putting it in the top tier of agentic coders next to GPT-5.5 (82) and Gemini 3.1 Pro (80.2). 1M context, adaptive thinking on by default; the daily workhorse for Cursor / Zed / Cline users who want closed-model diff quality.
Agent: TB2 80.4 makes Sonnet 5 a top-tier agent driver (Sonnet 4.6 was mid-tier at 53.4). SWE-Bench Pro 63.2 lands between GPT-5.5 (58.6) and Opus 4.7 (69.2). Anthropic's tool-use SDK keeps it the most reliable closed model for hand-rolled agent loops.

- MMLU-Pro—
Coding: Cursor / Cline / Zed power-user pick when budget allows. SWE-Pro 69.2 and TB2.1 74.6 say it all — best closed model for real software engineering. Simon Willison describes it as 'a modest but tangible improvement' over Opus 4.7 (simonwillison.net/2026/May/28/claude-opus-4-8/). 4x less likely to miss code flaws vs predecessor.
Agent: Top closed agent with SWE-Pro 69.2 and new 'dynamic workflow' tooling (Claude Code 2.1.154). Powers production Hermes / Open-Claude setups. TB2.1 74.6 per Anthropic self-report — TB2.0 leaderboard not yet updated. Fast mode at $10/$50 reduces agentic cost vs standard rate.
Our picks for this build
Sourced from the State of Local AI snapshot — the model + quant + backend we'd actually deploy on this hardware today, with the recipe in the setup guide below.
Qwen 3.6 27B (dense)
Apr 22 2026. Dense 27B that hits 77.2% SWE-Bench Verified — beats much larger MoEs on coding. Vision-capable, 262 K native context. Best single-24 GB-card coder right now.
- HLE24.0%
- TB259.3%
- SWE-Pro53.5%
- SWE-Ver77.2%
Coding: The new local-coding king under 200B on r/LocalLLaMA — matches Claude Opus 4.5 on TB2 per Qwen's launch claims, beats Qwen3.5-397B-A17B on every coding eval. Daily-driver pick for Cline at Q4_K_M on a single Pro 6000 or M3 Ultra. Confirmed running ~160 tok/s with MTP on RTX 6000 per dzombak.com vLLM recipe.
Agent: Genuinely useful in Open-Claude / Claude Code routing — community reports 30-min+ sessions completing without derail. Still trails closed frontier on the very longest loops. Caps at agents:3 per site rule (sub-200B, TB2 59.3 below 65% threshold).
Qwen 3.6 35B-A3B (MoE)
Apr 2026 release. 35B / 3B active MoE — beats Gemma 4-31B on agentic coding, matches Sonnet on most vision tasks. Native 262 K context (extensible to 1 M), ~18 GB at Q4. The new local-coding king under 200 B.
- HLE21.4%
- TB251.5%
- SWE-Pro49.5%
- SWE-Ver73.4%
Coding: r/LocalLLaMA's pick for fast local coding on a 24 GB card at Q4_K_M — 3B active so it's snappy. Vibes-codes 'perfectly fine' in OpenCode/Claude Code per multiple weekly-megathreads. Simon Willison's pelican test (April 2026): 'Qwen3.6-35B-A3B on my laptop drew me a better pelican than Claude Opus 4.7' — still resonating in the community.
Agent: Solid in 5-15 tool-hop loops in Cline. Long-horizon (60+ min) Open-Claude sessions still lose thread — 3B active is a ceiling on planning. Note: Qwen-self-reported TB2 51.5 vs community 23-24% — gap is harness-driven (Terminus-2 vs little-coder agent).
Mistral Medium 3.5 128B
Apr 30 2026. Western 128B dense with vision + 256 K context. 77.6% SWE-Bench Verified; first credible mid-tier open-weight from Mistral in months. Modified MIT.
- SWE-Ver77.6%
Coding: Apr 30 2026 launch with built-in PR-opening coding agent. Western 128B-dense with vision + 256K — early r/LocalLLaMA reports treat it as a credible Cline driver but trailing Qwen 3.6-27B on real refactors.
Agent: Mistral's agent SDK is OK; in Open-Claude it handles ~20-min sessions reliably. Long-horizon ceiling still unclear pending community evals.
