Standalone agent-first platform with CLI, SDK, and managed agents
AI-powered IDE built as a fork of Visual Studio Code, designed with an 'agent-first' paradigm where autonomous AI agents plan, execute, and validate code. Features two primary views: Editor View (traditional IDE with agent sidebar) and Manager View (control center for orchestrating multiple parallel agents across workspaces). Agents generate verifiable 'Artifacts' including task lists, implementation plans, screenshots, and browser recordings. Supports multiple AI models including Gemini 3 Pro, Gemini 3 Deep Think, Gemini 3 Flash, Claude Sonnet 4.5, and open-source GPT variants. Agents have direct access to editor, terminal, and integrated browser, and learn from previous interactions.
Why: Antigravity 2.0 is Google's most credible bid for the agentic IDE seat. The new CLI and SDK make it competitive with Cursor, Claude Code, and Codex for terminal-first and automation workflows.

Anthropic's frontier model, currently first on the Artificial Analysis Intelligence Index
Claude Opus 5 is Anthropic's flagship model, released 24 July 2026 with a 1M-token context window and five selectable effort levels (low, medium, high, xhigh, max). Effort is the main control: output token spend runs roughly 8x from low to max, and Artificial Analysis measures a 407-Elo spread in task quality across that range, so the same model behaves like several different price and capability tiers. API pricing is $5 per million input tokens and $25 per million output, with cache writes at $6.25 and cache hits at $0.50. It leads the Intelligence Index at 60.7 and tops the Coding Agent Index, scoring 89 percent on Terminal-Bench v2.1 at max effort and 53 percent on Humanity's Last Exam.
Why: It is the current number one on the independent Artificial Analysis Intelligence Index, and it got there while costing less per task than the model it displaced: $2.03 average per index task against Fable 5's $2.75. The effort dial is the reason to pick it over a fixed-tier model, because one integration covers cheap high-volume calls and expensive long-horizon agent runs.

OpenAI's top-tier model for complex professional work
GPT-5.6 Sol is the highest-capability model in OpenAI's GPT-5.6 family, released July 9, 2026 after a limited preview starting June 26. It has a 1.05M-token context window with up to 128K output tokens, and is positioned for complex professional work: advanced coding, scientific and technical reasoning, long-document analysis, computer use, and multistep agent workflows. It sits alongside the cheaper Terra and Luna tiers in the same family: Sol is $5 input and $30 output per million tokens, Terra $2.50 and $15, Luna $1 and $6, and on July 30, 2026 OpenAI cut Luna's price by 80% and Terra's by 20%. Free and Go users of ChatGPT get Terra; paid users choose any of the three and set effort per model.
Why: Sol ranks third overall on the Artificial Analysis Intelligence Index at 58.9, behind Claude Opus 5 and Claude Fable 5, a genuine top-tier frontier model rather than an incremental update, and OpenAI's clear flagship pick for the hardest professional-grade tasks.

Anonymous 1M-context reasoning model available free through OpenRouter
Ox Alpha is a stealth AI model that appeared on OpenRouter and OpenCode on 20 August 2026. Its creator is unidentified, and OpenRouter routes requests to an anonymous third-party provider. The model accepts text, images and video, outputs text, and supports a 1,048,576-token context window with up to 131,072 tokens of output. Independent serving-layer forensics published on 22 August 2026 point to Zhipu AI's GLM-5.x infrastructure as the leading theory — a Java stack trace naming Zhipu's internal API classes, matching error-code dialects, 30/30 tokenizer alignment with GLM-5.3, and identical video-encoder behaviour to GLM-5V-Turbo. Zhipu has not confirmed this.
Why: The combination of a one-million-token context window, multimodal inputs, free pricing during the preview, and rapid adoption by coding-agent builders makes it worth tracking even before its creator is known. Within a day of launch, coding agents had pushed billions of tokens through it, suggesting real production interest rather than curiosity traffic. Preliminary independent DeepSWE testing also places it ahead of Claude Fable 5 and GPT-5.6 Sol on a small task subset.

Google's coding workhorse, three weeks after 3.6 Flash
Gemini 3.7 Flash is Google's Flash-tier model, released 13 August 2026 — three weeks after Gemini 3.6 Flash and ahead of the still-delayed Gemini 3.5 Pro. Google calls it its most capable Flash model, built for complex coding, agentic workflows and reliable multi-step execution, and it ships as model ID gemini-3.7-flash. On every benchmark Google published it improves on 3.6 Flash: DeepSWE v1.1 65.3% against 49.0%, FrontierCode 1.1 Main 43.6% against 34.4%, GDP.pdf 34.0% against 22.0%, AutomationBench 30.4% against 17.0%, and WebDev Arena 1588 Elo against 1538.
Why: It is the cheapest route to a current-generation Google coding model. Introductory pricing runs at half the standard Flash rate until the end of 2026, and the published jump over 3.6 Flash is large enough to matter on exactly the agentic and web-development work Flash-tier models are usually bought for.

Cognition's Devin-exclusive coding model, RL-trained on top of Kimi K3
SWE-2 is Cognition's flagship coding model, released September 12, 2026 and built by reinforcement-learning post-training on top of Moonshot AI's 2.8-trillion-parameter open-weight Kimi K3. Cognition reports it matches Claude Fable 5.1 on FrontierCode 1.1 Main (both around 50%) at roughly 64% lower inference cost, scores 73.0% on DeepSWE 1.1 and 92.8% on Terminal-Bench 2.1, but trails Fable 5.1 and GPT-6 Astra by around 30 points on the harder Terminal-Bench 4. It ships with no open weights and no self-serve public API: it is exclusive to Devin's desktop app and CLI, with a Devin Web and Fusion rollout planned. Usage inside Devin is free through mid-October 2026; after that it requires a paid Devin plan, and separate enterprise credit-based API access is priced at $3.00 per million input...
Why: SWE-2 is a genuine data point in the trend of labs fine-tuning open-weight Chinese base models to compete with closed frontier coding models on price, and it is the model Cognition is betting Devin's entire value proposition on. The catch is access: every benchmark above is Cognition's own, unverified independently, and there is no way to use the model outside Devin's ecosystem.

Z.ai's post-trained coding and agentic model on the GLM-5.2 base
GLM-5.3 is Z.ai's flagship coding and agentic model, released 14 August 2026. It uses the same 743B-parameter mixture-of-experts base as GLM-5.2, with Z.ai attributing the gains to scaled post-training rather than a new pre-training run. It targets long-horizon agentic coding, business-process automation, defensive security work and tasks that span many steps. The model supports three reasoning-effort levels and a 1M-token route for coding plans.
Why: The Terminal-Bench 3.0 score moved from 4.6% to 28.3%, DeepSWE v1.1 from 46.2% to 66.9%, and CyberGym from 77.2% to 84.5% — all on the same base as GLM-5.2. That is a real signal about post-training returns, even if most numbers are vendor-run and weights are not yet released. It is also reported as one of the fastest models in its class, at roughly 115 tokens per second.

Alibaba's 2.4-trillion-parameter flagship, currently in preview
Qwen 3.8-Max is Alibaba's largest model yet, announced July 19, 2026, at 2.4 trillion total parameters using a sparse Mixture-of-Experts design. It's multimodal (text, images, video, documents) with a context window in the ~1M-token range (983,616 tokens per Qwen Cloud metadata) and a 131,072-token max output. It's live now as qwen3.8-max-preview through Alibaba's Token Plan, Qoder, and QoderWork at 10% of eventual standard pricing, targeting coding, agentic workflows, and long-horizon 'professional cowork' tasks. Alibaba says open weights are coming but hasn't published a date, license, model card, or full benchmark table yet; the independent number available is Artificial Analysis, which places the preview at 53.4 on its Intelligence Index, rank 11.
Why: Qwen 3.8-Max is Alibaba's answer to the current wave of massive open-weight-adjacent models from Chinese labs, and the discounted preview pricing makes it worth evaluating early even before the full release details land.

753B open-weight MoE coding model with a 1M-token context, MIT licensed
GLM-5.2 is Zhipu AI's (Z.ai) flagship open-weight model, released 13 June 2026 under an MIT licence with weights published on Hugging Face at zai-org/GLM-5.2. It is a 753B-parameter mixture-of-experts model activating roughly 40B parameters per token, with a 1M-token context window and 128K maximum output. The headline architectural change is IndexShare, which reuses the same indexer across every four sparse attention layers; Z.ai reports this cuts per-token compute by about 2.9x at full 1M context. It targets long-horizon agentic coding, multi-file refactors, terminal work, and tasks that run for many steps rather than single completions.
Why: The strongest open-weight coding model published to date: 62.1 on SWE-bench Pro against GPT-5.5's 58.6, and 81.0 on Terminal-Bench 2.1, at roughly a sixth of GPT-5.5's API price. The MIT licence carries no regional restrictions, so the weights can genuinely be self-hosted commercially, which is the reason to choose it over a closed model of similar strength.

HOW TO CHOOSE
What actually decides between AI coding tools:
- Autocomplete, chat, or agent: Three different products. Completion speeds up typing, chat speeds up thinking, and an agent takes a task and runs. Agents save the most time and require the most review.
- Which model is underneath: Most of these tools are a harness around someone else's model. Ask which one, whether you can change it, and whether you can bring your own key — it decides both quality and cost.
- How it reads your codebase: On a large repository, retrieval quality matters more than model quality. A tool that indexes well and pulls the right three files beats a stronger model given the wrong ones.
- What it does with your code: Check whether code is retained, trained on, or leaves your machine at all. Zero-retention terms and local execution are available and are usually the deciding factor for work under NDA.
- Review and undo: An agent that edits fifteen files is only usable if you can see and stage each change. Diff review, checkpoints and clean git integration are what make agentic editing safe.
- Cost model: Flat seat pricing is predictable; usage-based pricing tracks the frontier but can surprise you. Agentic runs burn far more tokens than chat, so measure on your real workload.
