Mistral: Devstral Small 1.1
By Mistralai
Released: 2025-07-10
Mistralai Devstral Small, developed by Mistral AI, features 24B parameters and 131k-token context window. Devstral Small 1.1 is a 24B parameter open-weight language model for software engineering agents, developed by Mistral AI in collaboration with All Hands AI. Finetuned from Mistral Small 3.1 and released under the Apache 2.0 license, it features a 128k token context window and supports both Mistral-style function calling and XML output formats. Designed for agentic coding workflows, Devstral Small 1.1 is optimised for tasks such as codebase exploration, multi-file edits, and integration into autonomous development agents like OpenHands and Cline. It achieves 53.6% on SWE-Bench Verified, surpassing all other open models on this benchmark, while remaining lightweight enough to run on a single 4090 GPU or Apple silicon machine. The model uses a Tekken tokenizer with a 131k vocabulary and is deployable via vLLM, Transformers, Ollama, LM Studio, and other OpenAI-compatible runtimes. Available at $0.1/1M tokens.

Claude Opus 4.8
Claude Opus 4.8 is Anthropic's June 2026 flagship model, succeeding Opus 4.7. It posts a headline score of 81 on the hardest agentic coding and reasoning suites, holds long-horizon tool-use plans together across far more steps, and is notably more candid about its own uncertainty - refusing to fabricate rather than confidently pressing on. It is the default choice for serious agentic and software-engineering workloads.
Anthropic Mythos 1
Mythos 1 is the full release of Anthropic's specialised, security-focused system, graduating from the guarded Claude Mythos Preview. Built around Project Glasswing, it pairs frontier reasoning with defensive security tooling - vulnerability analysis, triage and incident response - deployed with heavy oversight and auditability. It runs alongside the general-purpose Claude family rather than replacing it.
