Best LLM for Coding
Coding is where model quality is easiest to feel — a weak model wastes more of your time than it saves. But the strongest coding model is also the priciest, and for most day-to-day work a tier down is indistinguishable.
Best value pick
GLM-5.3-Flash
Z.ai (Zhipu AI) · Coding Arena 1607 · about $23.75/month at 100,000 calls. The top-ranked Kimi K3 costs $1,200.00/month — you save $1,176.25/month with GLM-5.3-Flash.

Intelligence scores are community Arena ratings from LMArena / arena.ai, used under CC BY 4.0. Snapshot last refreshed 18 September 2026. Scores are a relative signal, not an absolute measure of capability. A Measured score was voted on directly; an Estimated score is inherited from an identical base model (a regional/creator-prefixed hosting duplicate). See our methodology.
Why picking isn’t obvious
Code quality depends on more than a leaderboard: context window (for large files), tool/function calling (for agents and editors), and latency all matter. We rank on the coding Arena and require tool calling, then surface the cheapest model that still clears the bar.
FAQ
What is the best value LLM for coding?
GLM-5.3-Flash is the cheapest model that still clears our quality bar for this task, at about $23.75/month for 100,000 calls (1,500 in / 500 out). It scores 1607 on the Coding Arena.
Is the most expensive model worth it for this?
Kimi K3 tops the Coding Arena but costs about $1,200.00/month here — roughly $1,176.25/month more than GLM-5.3-Flash for 72 extra Arena points. For most workloads that gap is not worth the premium.
