DeepSeek V4.1 Flash is the best cheap AI for coding in October 2026. It costs about $0.30/$1.20 per million tokens on hosted APIs, its weights are MIT-licensed, and DeepSeek says it beats its own V4-Pro flagship on coding — a claim not yet independently verified. Cheaper still, Qwen 3.8 Flash ($0.15/$0.47) and GLM-5.3 Flash ($0.15/$0.50) are capable open-weight coders for simpler tasks. Every cheap coder needs review before its code ships.
The safest coding default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
DeepSeek V4.1 Flash is the strongest answer here for coding — pick it when quality of output matters more than the $0.30/1M/1M input you pay for it.
Claude Haiku 5.5 handles the same job for about 60% less per token. Start here and only move up if the output is not good enough.
Qwen 3.8 Flash is the fastest of these for coding — worth it when latency is what the reader notices, not the last few points of reasoning depth.
DeepSeek V4.1 Flash is the best cheap coding model, at about $0.30/$1.20 with open weights.
Qwen 3.8 Flash and GLM-5.3 Flash are cheaper still at about $0.15 per million input tokens.
Kimi K2.7 Code is a coding specialist built for token efficiency in agent loops.
Choose DeepSeek V4.1 Flash for budget engineering throughput on real codebases.
Choose Qwen 3.8 Flash or GLM-5.3 Flash for tests, boilerplate and simple scripts at the lowest price.
Choose Claude Haiku 5.5 when you want a closed model with predictable behaviour from a major lab.
Switch the scoring lens to see whether the coding answer changes when cost, speed, or long-document depth leads the decision.

Scores out of 100 — how we evaluate models. “Est. month” is 10M in / 2M out at list price: a ceiling, no discounts.
Why each one is on the shortlist for coding, what it is genuinely good at, and where we would steer you away from it.
Ranked first here for coding: 89/100 on coding, with the widest margin of anything in this line-up.
DeepSeek's September 10, 2026 release, now its top API model: a natively multimodal, MIT-licensed model with 1M context that DeepSeek says beats its own V4-Pro on coding and agent work — V4-Pro traffic has been routed to it since September 14.
You need long single outputs (32K cap) or independently verified scores before you commit.
DeepSeek's current flagship in practice, since V4-Pro requests now run on it. Cheap and open, with coding claims that still need independent confirmation. A strong pick for self-hosting or budget pipelines with review.

Here for latency: it answers fastest of anything listed for coding, at 84/100 on coding.
Alibaba's preview of the Qwen4 architecture — 125B parameters with only 6B active per token, at sixteen cents per million input.
You need Alibaba's maximum capability — that is Qwen 3.8 Max — or a SWE-bench Verified number.
One of the best coding-score-per-dollar picks in the catalog. Route volume work here and reserve Qwen 3.8 Max or a frontier model for the hard cases.

For coding, DeepSeek V4.1 Flash (DeepSeek) is our pick. DeepSeek's open, cheap new default — V4-Pro now routes to it. It costs $0.3/1M input and $1.2/1M output tokens, with a 1.048576M-token context window — enough headroom for all but the largest coding jobs. Qwen 3.8 Flash is the closest alternative if it doesn't fit your setup.
Because the work it is built for overlaps closely with coding: high-volume coding assistance where review catches what the model misses and self-hosted deployments — the weights are on Hugging Face under the MIT licence. DeepSeek's current flagship in practice, since V4-Pro requests now run on it. Cheap and open, with coding claims that still need independent confirmation. A strong pick for self-hosting or budget pipelines with review.
On a moderate month — 10M input and 2M output tokens — DeepSeek V4.1 Flash runs about $5.40 at list price, with no batch or caching discounts applied, so treat that as a ceiling. Claude Haiku 5.5 is the cheaper route at roughly $2.00 for the same volume, if coding is high-volume enough for price to lead the decision.
DeepSeek's coding claims are self-reported and not yet independently verified; it trails on hard reasoning by DeepSeek's own account. Price varies by host and by time of day — check the rate you will actually pay. Avoid it if you need long single outputs (32K cap) or independently verified scores before you commit. None of that rules it out for coding on its own — but if one of those limits maps onto how you actually work, take the alternative on this page seriously rather than defaulting to the top pick.
Claude Haiku 5.5 at $0.1/1M input is the budget option here. Anthropic's budget model, now with adjustable reasoning, at $0.10/$0.50. Expect a quality step down on the hardest cases — the usual pattern is to route routine coding volume to Claude Haiku 5.5 and keep DeepSeek V4.1 Flash for the work where a wrong answer is expensive.
Qwen 3.8 Flash, rated very fast against DeepSeek V4.1 Flash's fast. Speed matters most for interactive and high-volume work; if your coding runs in the background, the slower and more capable model is usually the better trade.
