Qwen 3.5-27B Just Built Complete Backends from Scratch — 100% Compilation, 25x Cheaper
Qwen 3.5-27B generated complete backends with 100% compilation at 1/25th the cost of Claude Opus 4.6 — and the output quality is nearly identical. The benchmark proves it.
AutoBE vs. Claude Code: 3rd-gen coding agent developer's review of the leaked source code
We learned a great deal from the leaked Claude Code source code. What separates a 2nd-generation agent (Claude Code) from a 3rd-generation one (AutoBE), and where do they converge—this is a story of coexistence, not replacement.
Function Calling Harness: From 6.75% to 100%
6.75% first-try function calling success becomes 100% compilation via type schemas, compilers, and structured feedback. Dissecting the harness engineering behind AutoBe and Typia.

[AutoBe] We Built an AI That Writes Full Backend Apps — Then Broke Its 100% Success Rate on Purpose
How we rebuilt AutoBE from a one-shot prototype builder to a modular development platform, recovering from 40% to near-100% compilation success through RAG optimization, weak-model testing, and type-driven validation.

[AutoBe] Hardcore function calling benchmark in backend coding agent
AutoBE leverages LLM function calling throughout every phase rather than relying on plain text generation, including compiler AST structures with infinite depths — establishing the most extreme function calling benchmark ever.

[AutoBe] Built full-level backend applications with "qwen-next-80b-a3b" model
The AutoBE team has successfully tested the qwen3-next-80b-a3b-instruct model to generate three complete backend applications: To Do List, Reddit Community, and Economic Discussion Board.
Succeeded to build full-level backend application with "qwen3-235b-a22b" in AutoBE
AutoBE successfully generated a complete backend application without compilation errors using qwen3-235b-a22b model, consisting of 10 API functions and 37 DTO schemas.

[AutoBe] Qwen3-80B suddenly wrote doomsday AI mythology while generating a TODO app
During testing, the Qwen3-80B model unexpectedly generated approximately 3,000+ words of apocalyptic poetry instead of documentation while building a simple TODO application.
Built Reddit like community with AutoBe and AutoView (gpt-4.1-mini and qwen3-235b-a22b)
AutoBE demonstrated the ability to generate increasingly sophisticated backend applications beyond basic todo implementations using open-source and commercial AI models.
